FDA warns consumers to avoid sexual enhancement pills

The Food and Drug Administration is warning men who take Man Up Now capsules to stop taking them immediately. The supplement contains a variation of an active ingredient found in Viagra that can lower blood pressure to dangerous levels, the agency says. It is marketed as an "herbal" and "all natural" sexual enhancement dietary supplements.

The FDA issued the warning after chemists analyzed Man Up Now and found it contains sulfoaildenafil, a chemical similar to sildenafil, the active ingredient in Viagra. When mixed with prescription drugs, such as nitroglycerin, the FDA says, Man Up Now can cause blood pressure to drop and that can lead to dizziness or light-headedness.
By Monday morning the FDA had not received any reports of problems surrounding Man Up Now. But if you are taking the supplement and have had any problems, the FDA suggests seeing a doctor and reporting it to the FDA.
Man Up Now is distributed by Synergy Distribution, LLC and is sold online and possibly in stores, according to the FDA. CNN contacted Synergy Distribution for comment and so far, hasn't heard back.
