Quick Facts

• Works by increasing blood flow to the penis, aiding in erection during sexual stimulation.
• Typically available in tablet form in various strengths.
• Common side effects include headache, flushing, and upset stomach.

What It Is and How It Works

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. These inhibitors work by blocking the enzyme PDE5, which can restrict blood flow. By inhibiting this enzyme, sildenafil promotes increased blood flow to specific areas, particularly the penis, when a person is sexually stimulated. This action helps achieve and maintain an erection sufficient for sexual activity.

Indications / Uses

While sildenafil is most commonly known for treating erectile dysfunction, it is also used under a different brand name to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs. Off-label uses exist, but they should only be explored under the supervision of a healthcare provider.

Dosage Forms and Typical Dosing Considerations

Sildenafil is available in tablet form, with dosages typically ranging from 25 mg to 100 mg for erectile dysfunction. The usual recommended starting dose is 50 mg taken approximately one hour before sexual activity. However, the dose can be adjusted based on efficacy and tolerability. For PAH, dosing differs and should be specifically guided by a healthcare provider.

It is essential to follow prescribed instructions, as individual factors such as age, kidney and liver function, and concurrent medications can affect dosage requirements and safety.

How to Take It Correctly Step-by-Step

To take sildenafil effectively, follow these general recommendations:

1. Take the medication approximately one hour before planned sexual activity.
2. Swallow the tablet whole with water.
3. It can be taken with or without food. A high-fat meal might delay its effectiveness.
4. If you miss a dose and plan to use it as needed, take it only when needed.
5. Store at room temperature away from moisture and heat.
6. Avoid alcohol consumption as it may increase the risk of side effects.
