Quick Facts

What It Is and How It Works

Sildenafil belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the enzyme PDE5, which results in an increase of cyclic guanosine monophosphate (cGMP) levels. This leads to smooth muscle relaxation and increased blood flow to specific areas, primarily the penis in case of erectile dysfunction, facilitating erection when combined with sexual stimulation.

Indications / Uses

The primary approved use of sildenafil is the treatment of erectile dysfunction (ED) in adult men. It is also used under the brand name Revatio to treat pulmonary arterial hypertension (PAH), a condition where there is high blood pressure in the vessels carrying blood to the lungs. Off-label uses include treatment of other forms of hypertension and some cases of Raynaud\’s phenomenon, though these uses should only be considered under medical supervision.

Dosage Forms and Typical Dosing Considerations

Sildenafil is most commonly available in tablet form in varying strengths, such as 25 mg, 50 mg, and 100 mg doses. The dosing may vary depending on the condition being treated, the patient\’s overall health, and the prescribing physician\’s guidelines. It\’s particularly important to adjust dosages for patients with liver or kidney impairments, those taking interacting medications, and elderly populations.

How to Take It Correctly Step-by-Step

Take sildenafil as prescribed by your healthcare provider, typically one hour before sexual activity, but it can be taken anywhere from 30 minutes to 4 hours prior. It can be taken with or without food, although a high-fat meal may delay its onset. Do not take more than one dose in 24 hours. If you miss a dose for PAH, take it as soon as you remember, but do not double up on the next one. Store the medication at room temperature away from moisture and heat.
