What It Is and How It Works

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the enzyme PDE5, primarily responsible for regulating blood flow in the penis. By inhibiting this enzyme, sildenafil increases blood flow to the penis during sexual stimulation, aiding in achieving and maintaining an erection. For PAH, it helps relax blood vessels in the lungs, reducing pulmonary blood pressure.

Indications / Uses

Sildenafil is primarily approved for erectile dysfunction (ED). It is also used to treat pulmonary arterial hypertension (PAH), where it helps improve exercise capacity and delay clinical worsening. Any other uses should be discussed with a healthcare provider, as they may be considered off-label and require professional supervision.

Dosage Forms and Typical Dosing Considerations

Sildenafil is available in tablet form, typically in doses of 25mg, 50mg, and 100mg. A 200mg dose is less commonly used and should only be taken under strict medical supervision, as higher doses increase the risk of side effects. Dosing requires careful consideration of the individual\’s health status, other existing medical conditions, and concurrent medications.

How to Take It Correctly Step-by-Step

  • Take the medication about 30 to 60 minutes before sexual activity.
  • The tablet can be taken with or without food; however, a high-fat meal might delay its action.
  • Do not exceed one tablet in a 24-hour period unless advised by a healthcare provider.
  • If you miss a dose taken for PAH, take it as soon as you remember, but skip it if it\’s almost time for your next dose.
  • Store at room temperature, away from moisture and heat.
  • Avoid alcohol as it can exacerbate certain side effects.
