Best Life Viga Tablets

Audience: Healthcare professionals and consumers

Best Life International warned consumers not to purchase or consume the product known as Viga. This product, which is being marketed as a dietary supplement, contains the unlabeled drug ingredient sildenafil, which may pose possible serious health risks to some users. Viga is sold in bottles of 30 tablets which are distributed by Best Life International Inc. This product is being promoted for increasing desire, confidence and sexual performance. The product is sold without medical prescription.

The interaction between nitrates and sildenafil can result in profound and life-threatening lowering of blood pressure. The use of nitrates in any form is an absolute contraindication for sildenafil users. The potential for this product to be taken by unknowing nitrate users is real, since erectile dysfunction is often a concurrent condition in patients with diabetes, hypertension, hyperlipidemia, smokers and patients with ischemic heart disease.
