Sildenafil, the active ingredient in Viagra , is classified as a prescription-only medication by the FDA in the U.S..

In the United States and many other countries, you cannot legally buy sildenafil without a prescription from a licensed healthcare provider. While buying medication without medical oversight might seem convenient, it presents severe legal and medical risks that are outlined in this paper.

All forms of sildenafil, including generics, require a prescription. Attempting to buy or sell it without one can lead to federal prison sentences of up to five years under pharmaceutical diversion laws.

Sildenafil can cause a lethal drop in blood pressure if taken with nitrates (common heart medications). A doctor's screening is essential to avoid this.

Some pills purchased without a prescription contain inconsistent amounts, while others may cause priapism (a painful erection lasting 4+ hours that causes permanent damage).

Erectile dysfunction (ED) is often an early indicator of serious health issues like cardiovascular disease or diabetes. Skipping a doctor's visit means these conditions may go undiagnosed. Viagra Without Prescription | ED Treatment | LloydsPharmacy
