Product description

These products are promoted for sexual enhancement and come packaged in bottles and/or "blister cards".

Reason for warning

The U.S. FDA informed consumers that these products are being recalled in the U.S. because they appear to contain undeclared sulfoaildenafil, which is an unauthorized substance similar to sildenafil and may pose similar heath risks. All lots of the above-named products with manufacture or distribution dates prior to June 17, 2010 are being voluntarily recalled by Novacare LLC.

Sildenafil is a prescription drug used to treat erectile dysfunction and should only be taken under the supervision of a health care practitioner.

Consumers wishing for more information on the recalls can contact Novacare LLC directly by calling 801-290-1738.

Health Canada has communicated in the past about products with the same name (but that are not necessarily the same products): Prolatis' and Stiff Nights.

Possible side effects

Sildenafil should not be used by individuals taking any kind of nitrate drug (e.g., nitroglycerine) as it can cause potentially life-threatening low blood pressure. Individuals with heart problems are at increased risk of cardiovascular side effects such as heart attack, stroke, chest pain, high blood pressure and abnormal heart beat. Other side effects include headache, facial flushing, indigestion, dizziness, abnormal vision, and hearing loss.
