Quick Facts Scannable

  • Primary Use: Erectile dysfunction (ED), sometimes used for pulmonary arterial hypertension (PAH).
  • Mechanism: Facilitates blood flow to the penis aiding erection upon sexual stimulation.
  • Common Form: Oral tablets.
  • Onset: Generally effective within 30 to 60 minutes.
  • Duration: Effects can last up to 4 hours.

What It Is and How It Works

Sildenafil is part of a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the PDE5 enzyme, which results in an increase in cyclic guanosine monophosphate (cGMP). Elevated cGMP levels lead to relaxation of smooth muscle and increased blood flow in specific areas of the body, including the penis. This makes it easier to achieve and maintain an erection when sexually stimulated. While it facilitates erection, it does not increase sexual desire.

Indications / Uses

The primary approved use of sildenafil is to treat erectile dysfunction in adult men. It is also sometimes used to treat pulmonary arterial hypertension (PAH) by relaxing blood vessels in the lungs to reduce blood pressure. High-dose formulations like the 200 mg tablet are generally considered for off-label use or under specialist supervision for patients who do not respond adequately to lower doses. It is important to note that such high doses increase the risk of potential side effects and should be administered cautiously.

Dosage Forms and Typical Dosing Considerations

Sildenafil is available in several forms, including tablets and suspensions. Commonly prescribed tablet strengths are 25 mg, 50 mg, and 100 mg. The 200 mg strength is not standard and should be approached with caution due to increased side effect risks. Dosing is typically considered based on the patient’s health status, other existing conditions, and response to the treatment. Dosing adjustments may be necessary for those with kidney or liver dysfunction, older adults, or those taking certain other medications.

It is crucial to follow the specific dose prescribed by a healthcare provider and not to exceed the recommended dose without their advice.

How to Take It Correctly Step-by-Step

To ensure effective administration, follow these steps:

  • Take sildenafil about 30 to 60 minutes before planned sexual activity.
  • It can be taken with or without food, but a high-fat meal may delay onset.
  • Swallow the tablet whole with a glass of water.
  • Avoid alcohol as it can exacerbate side effects and reduce effectiveness.
  • If a dose is missed in the context of daily use for PAH, take it as soon as remembered unless it’s close to the next dose.
  • Never take more than one dose per day.
  • Store at room temperature, away from moisture and heat.
