Specialty medications are typically covered on the fourth tier and/or require the use of a preferred specialty pharmacy 20mg tadacip visa impotence nasal spray. Oral specialty medications may be covered diferently than injectable specialty medications order tadacip with mastercard erectile dysfunction treatment chennai. Below are The Patient Protection and Afordable Care Act, answers to some of the most commonly asked commonly referred to as “health care reform,” questions about the prescription drug list.

If your tiers or is no longer covered, you may have to doctor feels a currently covered medication pay a diferent amount for that medication. How can i save money on my prescription Some high-cost medications have clinically medications? Meaning, they work the same or similar to another covered prescription You may be able to save money by switching medication or over-the-counter (available to a lower-cost medication. To help lower to see if a medication in a lower-cost tier may your overall health care costs, these high-cost work for you. If your doctor feels an alternative medication isn’t right for you, he or she can ask Cigna to consider approving coverage of your medication. So, a generic medication the same as a brand name medication in dosage form, active ingredient, strength, route of administration, quality, performance characteristics and intended use. Generics typically cost much less than brand name medications – in some cases, up to 80%–85% less. If your plan provides coverage for certain preventive prescription drugs with no cost-share, you may be required to use an in-network pharmacy to fll the prescription. If you use a pharmacy that does not participate in your plan’s network, the prescription may not be covered. Certain drugs may require prior authorization, or be subject to step therapy, quantity limits or other utilization management requirements. Your plan may cover additional medications; please refer to your enrollment materials for details. Cigna does not take responsibility for any medication decisions made by the doctor or pharmacist. Cigna may receive payments from manufacturers of certain preferred brand medications, and in limited instances, certain non-preferred brand medications, that may or may not be shared with your plan depending on its arrangement with Cigna. Depending upon plan design, market conditions, the extent to which manufacturer payments are shared with your plan and other factors as of the date of service, the preferred brand medication may or may not represent the lowest-cost brand medication within its class for you and/or your plan. In accordance with Texas and Louisiana state law, customers with afected beneft plans who receive coverage for medications that are removed from the prescription drug list during the plan year will continue to have those medications covered at the same beneft level until their plan renewal date.

We have answers We are the Asthma Society of Canada and we care about your lung health. The goal of asthma management is to keep asthma symptoms under control by reducing inflammation in your airways. You can help control your symptoms by avoiding asthma triggers and by using your asthma medications as prescribed. It will assist you in understanding what your medication does, how to take it properly and why an action plan is important. This booklet is for adults with asthma or parents with a child with asthma, and will address the following questions: What is good asthma control? Good asthma management includes education, avoiding triggers, using asthma medications properly and following a written action plan © 2007 Asthma Society of Canada, 4950 Yonge Street, Suite 2306, Toronto, Ontario Canada M2N 6K1. Use these steps to guide your discussions with your doctor, pharmacist and asthma educator. Step 3 Medication Step 1 Your doctor may prescribe Diagnosis Asthma controller medication Talk to your doctor about Learn what your your breathing difficulty medication does and Your doctor confirms you have how to take it properly asthma and may do tests Learn how a written Find out about asthma, what action plan can help you it is and how it can be controlled manage your asthma This step is discussed in the This step is discussed in booklet called Diagnosis this booklet called Medications Step 2 Triggers Find out what makes your asthma worse by keeping a diary and getting allergy tests Once you know what your allergic and non-allergic triggers are, you learn how to avoid them This step is discussed in the booklet called Triggers 2 © Asthma Society of Canada Step 4 Education Learn as much as possible. Ask your pharmacist and doctor lots of questions Read informational materials and visit www. Good asthma control means being able to participate in strenuous activity 4 © Asthma Society of Canada Reasons for poor asthma control If your asthma is poorly controlled, it might be because: You are not using your inhalers properly. Show your doctor or pharmacist how you use your inhalers You are being exposed to a trigger. Read the Asthma Basics Booklet called Triggers for information about things that can make your asthma worse. Talk to your doctor about allergy tests You are not using your controller medication regularly. Use your controller medication every day You may have something other than asthma, such as an infection, and you may need another different medication, in addition to your asthma medication One indicator of poor asthma control = needing your reliever inhaler 4 or more times a week because of breathing problems 5 Medications: Asthma Basics Booklet Controller medications Having asthma means having long-term inflammation in your airways. Avoiding your asthma triggers by modifying your environment is the best way to help reduce this swelling (see the Asthma Basics Booklet called Triggers), but it is often not enough to achieve and maintain good asthma control. Regular use of a controller medication, will treat the persistent inflammation of the airways. Inflamed airway and mucus Regular use of controller medicine Normal airway = normal function 6 © Asthma Society of Canada Controllers: Inhaled Corticosteroids Inhaled corticosteroids have an anti-inflammatory effect on the airways. When used regularly, inhaled corticosteroids reduce inflammation and mucus in the airways, making the lungs less sensitive to triggers. Everyone with asthma, including mild asthma, benefits from regular use of inhaled corticosteroids. When your asthma is poorly controlled, your doctor may prescribe an inhaled corticosteroid. It can take days or weeks for the inhaled corticosteroid to reduce the inflammation in your airways, so be patient. The longer you are using it, the less you will need to use your reliever medication.
We do this for one of the major inputs in the provision of medical care: prescription drugs cheap 20mg tadacip amex are erectile dysfunction drugs tax deductible. While one ultimately wants to measure the output of the health sector as the marginal improvement to health status from all goods and services (Abraham and Mackie 2005) purchase tadacip 20 mg overnight delivery erectile dysfunction zinc deficiency, there are nonetheless important uses of price indexes for the individual inputs, such as measuring productivity growth for the drug industry and parsing out the drivers of growth in spending. We begin with a discussion of two definitional issues that turn out to be numerically important. Section 3 discusses the relative merits of different aggregation methods as they relate to the drug industry. A review of what is known about the issue of quality change is given in Section 4 and Section 5 concludes with a summary of the issues. Definitional Issues We begin with a discussion of how the “product” provided by the drug industry should be defined and how quantity and price should be measured. The particular price that one pays for a drug depends importantly on the attributes of the drug: for example, active ingredient (sometimes called the “molecule”), strength (e. An important issue in this regard is how price indexes should handle the entry of generic drugs: should branded and generic versions of the same drug be considered the same or separate drugs? One landmark contribution of this literature was the demonstration that this distinction is numerically important for several prominent medications: Berndt, Cockburn and Griliches (1996) for antidepressants and Griliches and Cockburn (1994) for antibiotics. For price index purposes, one wants to define a homogeneous product, so that tracking its price over time does not reflect any changes in the good’s attributes. The issue is very similar to the problem of defining the market in antitrust cases: should the market be defined as aluminum foil or as all wrapping materials—foil, wax paper, saran wrap, etc. Consider a simple example where a branded antidepressant sells for $1 a day and its price stays constant. At some point, the branded drug loses patent protection and a generic version is introduced at 70 cents per day, with its price also remaining constant. As patients switch to the less-expensive generic drug, overall revenues received by the drug industry fall. Because price indexes are typically some function of weighted averages of price change, a price index that 4 considers the two drugs as separate products (i. This means that the reduction in revenues will be attributed to a drop in quantities, even if the number of patients or prescriptions did not change. At the other extreme, one can define the branded and generic versions as the same product (i. With this definition, the decline in revenues will translate into a decline in the average revenue, or the price. One caveat, however, is that the inert ingredients are often different for branded and generic drugs. The data are from Pharmetrics and are described in more detail in Aizcorbe and Nestoriak (2008). In our data, prices for generic drugs are, on average, 30% lower than the prices of their branded counterparts, suggesting that how one handles switches from branded to generic drugs could be numerically important. In our sample, the number of prescriptions filled for generic drugs grew from about 58% of all oral prescriptions in 2003 to over 60% in 2005. The literature has provided some methods for better folding generics into price indexes but some problems still remain. Even if these methods could, in principle, provide suitable first-order approximations to the problem, subsequent studies that attempted to implement these methods had difficulties: …. Future research should focus on the conditions under which the Feenstra, the Griliches and Cockburn or some other method is more likely to yield robust and plausible findings. Defining units of “quantity” How one defines the unit of measurement also has empirical implications for price measurement. Among the definitions for price that are typically used are 1) price per day of treatment, 2) price per prescription, and 3) price per package. Price per day of treatment is a widely used definition, used both in studies of cost decompositions and hedonic studies, but 6 requires information on the number of days of treatment associated with each prescription, as found in claims data. Of these two, health economists typically view the price per day as the superior choice (Crown, Ling and Berndt 2002) because price per prescription confounds changes in utilization and price (increases in the number of days per prescription are represented as an increase in price per prescription, for example). This is the definition underlying the Producer Price Index for drugs and the price index used in the pharmaceutical components of the Federal Reserve Board’s Industrial Production Index. Because tracking the price of each package holds constant the number of medications (e. For this comparison, we use only claims where all three pieces of information are available. Consistent with the discussion in Merlis (2000), price indexes based on price per day tend to show slower price growth than those based on price per prescription. Indexes based on price per package also grow faster than the preferred price per day definition, but the differences are less pronounced. To the extent that price per day of treatment is the preferred 7 definition, it is also unfortunate that the necessary data to measure it this way are not as readily available as data on number of prescription or packages sold. Aggregation Issues Once the product and unit of measurement are defined, one needs a formula to aggregate price changes across the individual products to obtain an aggregate statistic. The Fisher formula is a superlative index number formula that has been shown to be superior to other aggregation formulas (Diewert 1992). As discussed below, “chaining” indexes provides a way to bring new goods into the indexes more rapidly and, thus, more closely track the composition of goods sold in the market. We also discuss the Laspeyres index, as it is often used in official price indexes and cost decompositions. Price Indexes Price indexes provide a way to measure aggregate price change over some period by comparing the cost of purchasing a market basket at different points in time. The simplest formula is the familiar Laspeyres index, which is usually written: L I 0,1= [Σi Pi,1 Qi,0/ Σi Pi,0 Qi,0 ] (1) where 0 and 1 denote two periods in time, a base and current period, respectively, and i indexes goods that are sold in both periods. The Laspeyres tracks the cost of buying the Qi,0 basket at period 0 prices with the cost of buying it at period 1 prices. The index can also be written as a weighted average of price change: L I 0,1 = Σi wi,0 Pi,1 / Pi,0 (2) where the weights, wi,0, are the base period expenditure shares and the price relatives, Pi,1 / Pi,0 measure the price changes for individual drugs. The weights, or shares, are often called “relative importances” and have been the focus of much of the work in the literature. Written this way, it is easy to see that products in the base period market basket are only included in the index if they are sold in both periods (i. That is, the index does not include price change for new goods— 8 goods that entered the market between the two periods—or for goods that exited the market after the base period. Moreover, for goods that were sold in both periods, the Laspeyres fixes the relative importance of these goods at the base period levels and therefore does not reflect any changes in the composition of goods sold over time. A Fisher Ideal index provides relative importances that are more closely aligned with the composition of goods sold over time.

Kennedy’s research focuses primarily on access barriers to prescription medicines, medical care, rehabilitation, and long-term services, with particular emphasis on at-risk groups, including persons with disabilities, older adults, and the uninsured. Aminosalicylates can be used in Crohn’s disease or ulcerative colitis, however they are often more effective in ulcerative colitis. Aminosalicylates have been shown to independently induce and maintain remission in mild to moderate ulcerative colitis. However, recent research suggests that they often need to be used in conjunction with other therapies to adequately control inflammation and prevent complications in Crohn’s disease. Sulfasalazine is still used, however, some patients experience side effects due to the sulfa component (see below). Approximately 90% of those with intolerance to sulfasalazine can tolerate mesalamine. These agents all use the same mesalamine, but differ in terms of the medication coating. Mesalamine must be coated or placed in special capsules to ensure drug delivery to the intestine or colon. The difference in coating affects where the medication is released in the intestine or colon and how frequently the medication needs to be taken (once, twice, or three times daily). Rectal administration permits delivery of high dose therapy (targeted exactly where it is needed) and avoids systemic (body wide) exposure. In many cases, rectal therapies are used in conjunction with oral therapies for additional symptom improvement: Suppositories (Canasa®) deliver mesalamine directly to the rectum. A high proportion of patients with proctitis (inflammation in the rectum) will respond to mesalamine suppositories. These are usually given in single or twice- daily doses and can provide substantial relief from the urgency and frequency of bowel movements. A combination of rectal and oral therapies may be more effective than pills alone. Up to 80 percent of patients with left-sided colon inflammation benefit from using this therapy once a day. Side Effects and Special Considerations Overall, aminosalicylates are well tolerated and safe. While few medications have been thoroughly evaluated in pregnancy, these medications are considered generally safe to use during pregnancy. Specific issues with individual agents include: Sulfasalazine: A decrease in sperm production and function in men can occur while taking sulfasalazine. Rare side effects are hair loss, pancreatitis, or inflammation of the tissue surrounding the heart (pericarditis). Drug Interactions People taking several different medicines, whether prescription or over-the-counter, should always be on the lookout for interactions between drugs. Drug interactions may decrease a medication’s effectiveness, intensify the action of a drug, or cause unexpected side effects. Be sure to tell your doctor about all the drugs you are taking (even over-the-counter medications or complementary therapies) and any medical condition you may have. Even during times of remission, it is important to continue taking your medications as prescribed to prevent asymptomatic inflammation and future flares.

A c When feasible, care systems should support team-based care, community in- volvement,patient registries, and decisionsupport tools to meet patient needs. Thus, efforts to improve population health will require a combination of system-level and patient-level approaches. Practice recommendations, whether based on evidence or expert opinion, are intended to guide an overall ap- proach to care. The science and art of medicine come together when the clinician is faced with making treatment recommendations for a patient who may not meet the eligibility criteria used in the studies on which guidelines are based. Recognizing that one size does not ﬁt all, the standards presented here provide guidance for when and how to adapt recommendations for an individual. This has been accompanied by improvements in cardiovascular out- comes and has led to substantial reductions in end-stage microvascular complications. Nevertheless, 33–49% of patients still do not meet targets for glycemic, blood pressure, or cholesterol control, and only 14% meet targets for all three measures while also avoiding smoking (2). Evidence suggests that progress in cardiovascular risk factor control (particularly tobacco use) may be slowing (2,3).

Initially (a long time ago) people agreed on an order in which mathematical operations should be performed discount tadacip 20 mg amex erectile dysfunction without pills, and this has been universally adopted 20 mg tadacip fast delivery natural treatment erectile dysfunction exercise. E Next, any exponentiation (or powers) must be done – see later for a fuller explanation of exponentiation or powers. It is important to know how to multiply and divide fractions and decimals, as well as to be able to convert from a fraction to a decimal and vice versa. Fractions Before we look at fractions, a few points need to be defined to make explanations easier. Definition of a fraction A fraction is part of a whole number or one number divided by another. Thus in the above example, the whole has been divided into 5 equal parts and you are dealing with 2 parts of the whole. To reduce a fraction, choose any number that divides exactly into the numerator (number on the top) and the denominator (number on the bottom). A fraction is said to have been reduced to its lowest terms when it is no longer possible to divide the numerator and denominator by the same number. This process of converting or reducing fractions to their simplest form is called cancellation. Remember – reducing or simplifying a fraction to its lowest terms does not change the value of the fraction. If you have a calculator, then there is no need to reduce fractions to their lowest terms: the calculator does all the hard work for you! Equivalent fractions Consider the following fractions: 1 3 4 12 2 6 8 24 Each of the above fractions has the same value: they are called equivalent fractions. If you reduce them to their simplest forms, you will notice that each is exactly a half. Now consider the following fractions: 1 1 1 3 4 6 If you want to convert them to equivalent fractions with the same denominator, you have to find a common number that is divisible by all the individual denominators. For each fraction, multiply the numbers above and below the line by the common multiple. So for Fractions and decimals 27 the first fraction, multiply the numbers above and below the line by 4; for the second multiply them by 3; and the third multiply them by 2. So the fractions become: 1 4 4 1 3 3 1 2 2 × and and 3 4 12 3 4 12 6 2 12 1 1 1 4 3 2 , and equal , and , respectively. For example: 14 7 4 14 +7 – 4 17 + – = 32 32 32 32 32 To add (or subtract) fractions with the different denominators, first convert them to equivalent fractions with the same denominator, then add (or subtract) the numerators and place the result over the common denominator as before. For example: 1 1 1 3 2 4 3– 2 + 5 – += – + = = 4 6 3 12 12 12 12 12 Multiplying fractions It is quite easy to multiply fractions. You simply multiply all the numbers ‘above the line’ (the numerators) together and then the numbers ‘below the line’ (the denominators). For example: 2 3 2 ×3 6 × = 5 7 ×7 35 However, it may be possible to ‘simplify’ the fraction before multiplying, e. You can sometimes ‘reduce’ both fractions by dividing diagonally by a common number, e. You will probably encounter fractions expressed or written like this: 2 5 2 3 whichisthesameas ÷ 3 5 7 7 In this case, you simply invert the second fraction (or the bottom one) and multiply, i. A decimal number consists of a decimal point and numbers both to the left and right of that decimal point. Multiplying decimals Decimals are multiplied in the same way as whole numbers except there is the decimal point to worry about. If you are not using a calculator, don’t forget to put the decimal point in the correct place in the answer. At first, it looks a bit daunting with the decimal points, but the principles covered earlier with long multiplication also apply here. The decimal point is placed as many places to the left as there are numbers after it in the sum. This is particularly true in infusion rate calculations, as it is impossible to give a part of a drop or a millilitre (mL) when setting an infusion rate. If the number after the decimal point is 5 or more, then add 1 to the whole number, i. Converting decimals to fractions It is unlikely that you would want to convert a decimal to a fraction in any calculation, but this is included here just in case. The value of this multiple of 10 is determined by how many places to the right the decimal point has moved, i. The following table explains the Roman numerals most commonly seen on prescriptions. It doesn’t matter whether they are capital letters or small letters, the value is the same. The position of one letter relative to another is very important and determines the value of the numeral. Consider the following: 10 × 10 × 10 × 10 × 10 Here you are multiplying by 10, five times. Instead of all these 10s, you can write: 105 We say this as ‘10 to the power of 5’ or just ‘10 to the 5’. The small raised number 5 next to the 10 is known as the power or exponent – it tells you how many of the same number are being multiplied together. Now consider this: 1 1 1 1 1 1 × 10 10 10 10 10 10 10 10 10 10 Powers or exponentials 37 Here we are repeatedly dividing by 10. For short you can write: –5 1 10 instead of 10 10 10 10 10 In this case, you will notice that there is a minus sign next to the power or exponent. In conclusion: • A positive power or exponent means multiply the base number by itself the number of times of the power or exponent; • A negative power or exponent means divide the base number by itself the number of times of the power or exponent. You will probably come across powers used in the following way: 3×103 or5×10–2 This is known as the standard index form. It is a combination of a power of 10 and a number with one unit in front of a decimal point, e. This type of notation is seen on a scientific calculator when you are working with very large or very small numbers. It is a common and convenient way of describing numbers without having to write a lot of zeros. The manual or instructions that came with your calculator will tell you how to do this. See the section on ‘Powers and calculators’ for an explanation of how your calculator displays very large and small numbers. If you don’t know how to use your calculator properly, then there is always the potential for errors. The estimating process is quite simple: numbers are either rounded up or down in terms of tens, hundreds or thousands to give numbers that can be calculated more easily. Single-digit numbers should be left as they are (although 8 and 9 could be rounded up to 10). Estimating answers 43 Once the numbers have been rounded up or down, it’s possible to do a simple calculation, and the result is close enough to act as an estimate. No set rules for estimating can be given to cover all the possibilities that may be encountered.

This is an evidence-based educational service of the American Academy of Neurology. It is designed to provide members with evidence-based guideline recommendations to assist with decision-making in patient care. It is based on an assessment of current scientific and clinical information, and is not intended to exclude any reasonable alternative methodologies. Strong evidence = research studies with high-quality data collection, this shows that the treatment is either effective, ineffective, or harmful. Good evidence = data collection using a combination of high-and low-quality methods, this shows that the treatment is probably either effective, ineffective, or harmful. Moderate evidence = research studies with low-quality data collection, this shows that the treatment is possibly either effective, ineffective, or harmful. Epstein-Barr and Herpes Simplex) commonly result in hives that may be confused with a drug reaction. If a viral infection is ruled out, follow drug rechallenge guidelines outlined in the adult management guidelines (below); doses must be adjusted for age and weight. Identify the causative drug by rechallenging (restarting) each drug every 4 days according to Table 1 (example follows on next page). If a reaction occurs during drug rechallenge and the causative drug can not be discontinued, 1,3 drug desensitization will be necessary Drug desensitization should not be attempted with severe skin reactions or those involving the mouth or mucous membranes (e. Consider measuring liver function tests to rule out drug induced hepatic dysfunction (refer to “Hepatotoxicity” section, pages 12-13). If diarrhea occurs with multiple drugs, consider separating medication administration times a. If diarrhea continues and an alternate regimen can not be utilized consider the addition of an antimotility agent ® a. If suspected, the child should be referred to the Flick Memorial Tuberculosis Clinic for evaluation. Hepatotoxicity has not been reported with extensive use of lower doses (15-30mg/kg/d) in short course 2 regimens. If acute swelling is present, the affected joint should be aspirated and examined for urate crystals to confirm the diagnosis of acute gouty arthritis. Recurrent episodes may occur while the patient remains on pyrazinamide or ethambutol. Common and/or clinically important adverse drug effects and drug interactions are included. Rifampin and the other rifamycins may decrease serum levels/therapeutic effects of (list is not all inclusive): •antiarrhythmic agents: disopyramide, mexilitine, propaferone, tocainide •antifungals: fluconazole, itraconazole, ketoconazole •benzodiazepines: alprazolam, chlordiazepoxide, clonazepam, clorazepate, diazepam, estazolam, flurazepam, midazolam, quazepem, triazolam •β-blockers: bisoprolol, metoprolol, propranolol •calcium channel blockers: diltiazem, nifedipine, verapamil •cyclosporin •digoxin, digitoxin •estrogen (e. Delavirdine and ritonavir 22 should not be used in combination with any of the rifamycins. Uveitis appears to be a unique adverse effect of rifabutin that does not occur with rifampin. Tablets and capsules should be administered all together once a day except in very unusual situations (e. If medication administration times are divided, the entire dose of each drug should be given at one time (e. Isoniazid and rifampin should be administered 1 hour before or 2 hours after food ingestion for maximum drug absorption. If nausea and/or vomiting occurs, administer isoniazid and rifampin with food (better to give the drug with food and have some decreased absorption than to not have the patient ingest the drug at all because of the side effect). Options for patients who can not swallow tablets and capsules (some adults and infants/children) a. Liquid preparations 1) availability a) isoniazid is the only commercially available liquid product b) rifampin and pyrazinamide suspensions can be prepared from the tablets/capsules c) ethambutol suspensions can not be prepared because of drug stability problems 2) limitations of liquid preparations a) the volume of the liquid required for each dose may be too large for the patient to tolerate (especially in infants and children) b) diarrhea may occur due to the lactose and sucrose content in liquid preparations 26 b) prepared suspensions have limited stability c) some suspension are not palatable (bitter tasting) b. Crushing capsules and tablets 26,27 1) preferred to administration of liquid formulations a) drug stability is not an issue b) administration of a large volume of liquid in children is avoided 26,27 2) procedure a) open and empty capsule contents into mortar, place tablets in the mortar and crush to a fine powder with a pestle (or other suitable container and “crusher” if mortar and pestle are not available) b) mix the powder with a pleasant tasting substance to mask the taste of the pills i) juice ii) flavored syrup (e. Administer medication through a nasogastric tube 1) alternative for children who are unable or unwilling to ingest medications 52 Appendix 5 Technique for Medication Administration through an Oral (needleless) Syringe The following administration technique helps to minimize the amount of liquid medication spilled because of infant “squirming” or the amount spit out once it had been administered. The infant should be held in the arm or lap of the person administering medication. The infant’s arms closest to the caregiver should be extended behind the caregiver’s back. The infant’s other arm is held down by the caregiver’s arm as the medication is being administered. The medication in the oral or needleless syringe should be injected into the infant’s cheek at the gums toward the back of the mouth. The volume of medication injected at one time should be determined based on the child’s size (the entire dose may not be able to be injected at one time). Either animal-reproduction studies have not demonstrated a fetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the first trimester (and there is no evidence of a risk in later trimesters). Either studies in animals have revealed adverse effects on the fetus (teratogenic or embryocidal, or other) and there are no controlled studies in women or studies in women and animals are not available. There is positive evidence of human fetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e. Studies in animals or human beings have demonstrated fetal abnormalities, or there is evidence of fetal risk based on human experience, or both, and the risk of the use of the drug in pregnant women clearly outweighs any possible benefit.
