What is Viagra?

Viagra, also known as sildenafil citrate, is a prescription drug used to treat erectile dysfunction. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Viagra has been prescribed by doctors for over two decades and has proven to be effective in treating men with ED.

How Does Viagra Work?

Viagra works by helping men get and maintain an erection. This is achieved by blocking a protein called phosphodiesterase-type 5 (PDE-5) from working too quickly. The presence of PDE-5 can stop an erection by breaking down another protein called cyclic guanosine monophosphate (cGMP), which is released when sexual arousal occurs and causes more blood to flow into the penis. By blocking PDE-5, Viagra allows cGMP to work effectively, leading to an erection.

Dosage and How to Use

Viagra comes in different doses and is taken as needed to treat ED. It is most effective about one hour after it’s taken, but it can start working within 30 minutes to four hours. If Viagra doesn’t seem to work, it’s recommended to consult with a doctor who may suggest a higher dose or a different medication.

Side Effects and Precautions

Like all medications, Viagra can have side effects. These can include sudden vision loss, sudden hearing decrease or hearing loss, and an erection that lasts more than four hours. If any of these occur, it’s crucial to seek medical help immediately. Additionally, Viagra should not be taken with certain medications, such as nitrates often prescribed for chest pain, or guanylate cyclase stimulators for pulmonary hypertension.


Viagra has been a game-changer in the treatment of ED. However, like all medications, it should be taken under the supervision of a healthcare provider. Always consult with a healthcare provider before starting any new medication.
