ST LOUIS (MD Consult) - On December 13, 2010, the US Food and Drug Administration (FDA) issued a warning to consumers about use of Man Up Now, a product marketed as a dietary supplement for the purpose of sexual enhancement. The FDA analyzed the product and determined that it contains sulfoaildenafil, a chemical similar to sildenafil, the active ingredient in Viagra. Marketing materials for Man Up Now state that the product is "herbal" and "all natural," and consumers may mistakenly assume the product is harmless and poses no health risk.
Like sildenafil, sulfoaildenafil may interact with prescription drugs such as nitrates (eg, nitroglycerin) and cause dangerously low blood pressure in persons taking these types of products together. To date, the FDA is not aware of any adverse events associated with the use of Man Up Now capsules.
Nonprescription sexual-enhancement products promising rapid or long-lasting effects are likely to contain ingredients in FDA-approved drugs or variations of those ingredients. The FDA advises consumers who have experienced any adverse effects with the use of sexual enhancement products to discontinue use and to consult a health care professional. Adverse events that may be related to the use of these products should be reported to the FDA's Med Watch Program.
Man Up Now, distributed by Synergy Distribution LLC, is sold on Internet sites, online marketplaces, and possibly in retail outlets in single, double, and triple blister-packs, and in bottles containing 6-, 12-, and 30-count capsules.
圣路易斯(MD Consult)——2010年12月13日，美国食品药品管理局(FDA)警惕消费者谨慎使用Man Up Now这种用于增强性功能的营养品。FDA分析了这一产品后，发现其含sulfoaildenafil，一种西地那非的类似物(即“伟哥”的有效成分)。Man Up Now在其产品介绍中称其为“纯天然的中药”，消费者可能会误以为该产品无害，不会对健康造成危险。
与西地那非一样，sulfoaildenafil在与硝酸盐类药物(如硝酸甘油)同服时也能发生药物相互作用，引起低血压危险。迄今为止，FDA尚不知道使用Man Up Now胶囊相关的不良反应。
这些增强性功能的非处方药标称其快速持久的成分已通过FDA批准。FDA建议使用增强性功能保健品后发生任何不良反应的患者立即停药，并咨询医务人员。同时，将与这些产品使用相关的不良事件上报至FDA的Med Watch Program。
Man Up Now的销售商为Synergy Distribution有限责任公司，销售渠道包括网上销售、网上商店和零售药店，以单泡罩、双泡罩和三泡罩的包装形式及含6粒、12粒或30粒胶囊的瓶装形式出售。
