Physicians should advise patients of the potential for Viagra to augment the blood pressure lowering effect of alpha-blockers and anti-hypertensive medications. Concomitant administration of Viagra and an alpha-blocker may lead to symptomatic hypotension in some patients.

But still, the largest percentage of counterfeit drugs—the generic antibiotics, tuberculosis drugs, and malaria medicines so prevalent in the developing world—often go unmonitored, since many countries don’t even have their equivalent of the FDA. For these reasons, a handful scientists and engineers are trying to create cheap, nearly indestructible devices to test for counterfeits. They want to do what Pfizer does for pennies.Levitra is a medicinal drug that belongs to a class of drugs called phosphodiesterase inhibitors. It contains the chemical vardenafil, which is a PDE5 inhibitor used in the treatment of impotency or erectile dysfunction.Do not take Levitra with similar medicines such as avanafil (Stendra), sildenafil (Viagra), or tadalafil (Cialis).

Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition and a cause of decreased vision, including permanent loss of vision, that has been reported rarely postmarketing in temporal association with the use of all PDE5 inhibitors. Based on published literature, the annual incidence of NAION is 2.5-11.8 cases per 100,000 in males aged ≥50. An observational study evaluated whether recent use of PDE5 inhibitors, as a class, was associated with acute onset of NAION. The results suggest an approximate 2-fold increase in the risk of NAION within 5 half-lives of PDE5 inhibitor use. From this information, it is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or other factors [see Adverse Reactions (6.2)].
