Man Up Now Capsules: Consumer Warning - Undeclared Drug Ingredient
ISSUE: FDA warned consumers not to use Man Up Now capsules, marketed as a dietary supplement for sexual enhancement, because FDA analysis determined that the product contains sulfoaildenafil, a chemical similar to sildenafil, the active ingredient in Viagra. Like sildenafil, this chemical may interact with prescription drugs such as nitrates, including nitroglycerin, and cause dangerously low blood pressure.
BACKGROUND: 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 six-, 12-, and 30-count capsule bottles.
RECOMMENDATION: Consumers who have Man Up Now capsules should stop using them immediately.
