Understanding Sildenafil (Viagra)

Sildenafil, the active ingredient in Viagra, works by increasing blood flow to the penis. This allows for firmer erections.

How Sildenafil Works

It inhibits an enzyme called phosphodiesterase-5 (PDE5). PDE5 normally breaks down cyclic GMP, a molecule responsible for relaxing the muscles in the penis. By blocking PDE5, sildenafil allows cyclic GMP levels to rise, resulting in increased blood flow.

Taking Sildenafil Safely

    Follow your doctor’s prescribed dosage carefully. Never exceed the recommended dose. Avoid taking sildenafil with nitrates, as this combination can cause a dangerous drop in blood pressure. Inform your doctor about all other medications you are taking, including herbal supplements. Common side effects include headache, flushing, nasal congestion, and upset stomach. These are usually mild and temporary. Seek immediate medical attention if you experience chest pain, dizziness, or prolonged erection (priapism).

Sildenafil and Other Medications

Sildenafil can interact with several medications. Consult your doctor or pharmacist before using sildenafil if you take any of the following:

Alpha-blockers Antihypertensives Certain antifungals HIV protease inhibitors

Possible Contraindications

Sildenafil is not suitable for everyone. Individuals with certain heart conditions, low blood pressure, or a history of stroke should avoid taking it. People with severe liver or kidney disease should also exercise caution. Always discuss your medical history with your doctor before starting sildenafil.

Understanding Your Options

If you experience erectile dysfunction, speak to your doctor. They can help determine the underlying cause and recommend appropriate treatment options, including sildenafil or alternative therapies.
