Quick Facts
- Sildenafil is used to treat erectile dysfunction (ED).
- It works by increasing blood flow to the penis to help achieve and maintain an erection.
- Commonly available in tablet form.
- Onset time is typically within 30 to 60 minutes.
- Common side effects include headache, flushing, and upset stomach.
- Potentially serious interactions with nitrates and certain blood pressure medications.

What It Is and How It Works
Sildenafil is classified under a group of medicines known as phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the action of PDE5, a chemical in the body that breaks down a substance called cyclic GMP, which facilitates the relaxation of smooth muscle cells and increases blood flow. By inhibiting PDE5, sildenafil helps maintain cyclic GMP concentrations necessary for an erection to occur in response to sexual stimulation.
Indications / Uses
Sildenafil is primarily prescribed for treating erectile dysfunction, allowing men with this condition to achieve and maintain an erection sufficient for sexual activity. Occasionally, it may be used off-label for conditions like pulmonary arterial hypertension (PAH), but such uses should always be managed by a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Sildenafil is usually available in tablet form, with common strengths being 25 mg, 50 mg, and 100 mg. In some cases, compounded formulations or injectables may be used for other indications like pulmonary arterial hypertension.
Dosing decisions should incorporate factors like age, overall health, and potential interactions with other medications. While healthcare providers typically start treatment with a lower dose to minimize side effects, adjustments may be necessary based on individual response and tolerability.
How to Take It Correctly Step-by-Step
It\’s important to follow your healthcare provider\’s instructions exactly when taking sildenafil. Here are some general guidelines:
- Take the tablet about 30 to 60 minutes before sexual activity.
- Sildenafil can be taken with or without food, but it may take longer to work if taken with a high-fat meal.
- Do not take more than once a day.
- If a dose is missed (in the case of non-sexual activity doses like treating PAH), take it as soon as you remember unless it\’s almost time for your next dose.
- Store at room temperature away from moisture and heat.
