On a press release dated March 21, 2013 the FDA released a warning cautioning consumers that the “Stiff Days” Erectile Dysfunction pills may not be as natural as they claim.
Due to an overwhelming increase of the inclusion of hidden drugs and chemicals in over the counter herbal remedies the FDA has begun testing, in their capacity, a number of natural remedies. Pills for erectile dysfunction routinely contain sildenafil- the active ingredient in Viagra. Sildenafil works by inhibiting an enzyme (cGMP-phosphodiesterase type 5) which promotes the decomposition of cGMP, facilitating blood flow to the penis. When taken in conjunction with a drug that uses nitrates the blood pressure could be lowered to potentially fatal levels.
Although some bottles bear a warning to men currently taking nitrates, the chemical in question, sildenafil, is not listed as an ingredient on the bottle and is contradictory to the company’s claim to be an, “All Natural Herbal Supplement”. Currently Viagra is the only drug containing sildenafil that is approved by the FDA to treat erectile dysfunction.
Who is at risk? Men who take drugs using nitrates should immediately discontinue the use of a product containing sildenafil. Drugs to treat hypertension, diabetes, high cholesterol or heart disease frequently contain nitrates. If you have experienced any negative side effects, the FDA encourages you to speak to your healthcare professional immediately
