What It Is and How It Works

Sildenafil citrate is a medication that belongs to the phosphodiesterase type 5 (PDE5) inhibitors, classified for use in treating erectile dysfunction. It works by inhibiting the PDE5 enzyme in the corpus cavernosum of the penis, which is involved in regulating blood flow. When PDE5 is inhibited, the levels of cGMP increase, leading to smooth muscle relaxation and improved blood flow, enabling an erection in response to sexual stimulation.

Indications / Uses

The primary indication for sildenafil citrate is for the treatment of erectile dysfunction in men. In some cases, it may be used for pulmonary arterial hypertension (PAH) under different brand names and dosages. Due to potential risks and side effects, off-label uses should only occur under strict medical supervision.

Dosage Forms and Typical Dosing Considerations

Sildenafil is available in tablet form, typically in doses of 25mg, 50mg, and 100mg. While 200mg is mentioned, it is not commonly prescribed and highlights the importance of medical supervision when discussing higher doses. Dosing may vary based on individual health factors, including age, kidney or liver function, and the presence of other medical conditions. It\’s essential for patients to adhere to the dose prescribed by their healthcare provider.

How to Take It Correctly Step-by-Step

  1. Take sildenafil about 30 to 60 minutes before planned sexual activity.
  2. Do not exceed more than one dose in a 24-hour period.
  3. Can be taken with or without food, but high-fat meals may delay effectiveness.
  4. If a dose is missed (though it is taken as needed), take as soon as remembered but not if it would mean overlapping doses.
  5. Store at room temperature away from moisture and heat.
  6. Avoid alcohol as it might amplify side effects.
