What It Is and How It Works
Sildenafil citrate is a medication classified as a phosphodiesterase type-5 (PDE5) inhibitor. It works by blocking the enzyme PDE5, which results in the relaxation of blood vessels and improved blood flow. Specifically for erectile dysfunction, this action allows for increased blood flow to the penis, which helps achieve and maintain an erection suitable for sexual activity when combined with sexual stimulation.
Indications / Uses
The primary and approved use of sildenafil citrate 100mg is for the treatment of erectile dysfunction in adult men. While it is predominantly prescribed for ED, sildenafil may sometimes be recommended off-label by healthcare providers for other conditions such as pulmonary arterial hypertension. It is essential, however, that any use outside of approved indications follow a clinician\’s direct guidance and supervision.
Dosage Forms and Typical Dosing Considerations
Sildenafil citrate is commonly available in oral tablet form, and the typical dosing for erectile dysfunction is 50mg to 100mg taken as needed, approximately 30 to 60 minutes before sexual activity. The dose should not exceed 100mg per day and adjustments may be necessary based on efficacy and tolerance. Factors such as age, renal function, liver function, and concurrent medications can influence the appropriate dose, which is why any dose adjustments should be made under a healthcare provider\’s supervision.
How to Take It Correctly Step-by-Step
- Take sildenafil citrate orally with water, about 30 to 60 minutes prior to planned sexual activity.
- It can be taken with or without food, but a high-fat meal may delay its onset of action.
- Do not take more than once daily.
- If a dose is missed (in the event it\’s used for conditions other than ED), take it as soon as remembered, unless it\’s close to the next scheduled dose.
- Store the medication at room temperature, away from moisture and heat.
Side Effects Common to Serious

Contraindications & Precautions
Sildenafil citrate should not be used in individuals with known allergies to any of its components.

Caution is needed in individuals with cardiovascular conditions, liver or kidney diseases, and in older adults. Its safety in pregnant or breastfeeding women has not been established.
Drug, Food, and Supplement Interactions
