What It Is and How It Works
Sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), primarily found in the corpus cavernosum of the penis. By blocking this enzyme, sildenafil enhances the effect of nitric oxide, a chemical released during sexual stimulation, which relaxes muscles in the blood vessels of the penis and increases blood flow, facilitating an erection.
Indications / Uses
The primary indication for sildenafil is the treatment of erectile dysfunction in men, helping them achieve and maintain an erection during sexual activity. Additionally, sildenafil is indicated for the treatment of pulmonary arterial hypertension, a condition characterized by high blood pressure in the blood vessels of the lungs. Off-label uses should be discussed with a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Sildenafil is available in various forms, including 25 mg, 50 mg, and 100 mg tablets. The typical recommended starting dose for erectile dysfunction is 50 mg taken as needed, approximately one hour before sexual activity. The maximum recommended dosing frequency is once per day. Dosage adjustments may be necessary for people with liver or kidney impairments or older adults.
How to Take It Correctly Step-by-Step
Take sildenafil exactly as prescribed by your doctor. It can be taken with or without food, but a high-fat meal may delay its onset. Do not take more than one dose per day. If you miss a dose for pulmonary arterial hypertension, take it as soon as you remember, but do not double the dose. Store the medication at room temperature away from moisture and heat.

Pregnancy and breastfeeding considerations require consultation with a healthcare provider.
Drug, Food, and Supplement Interactions
Sildenafil can interact with other medications such as nitrates, riociguat, certain antifungals, and antibiotics like erythromycin, affecting its efficacy and safety.
