What It Is and How It Works
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the degradation of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells lining penile blood vessels. This leads to relaxation and dilation of these vessels, allowing increased blood flow and resulting in an erection when combined with sexual stimulation.
Indications / Uses
Primarily, sildenafil is used to treat erectile dysfunction in men, allowing for improved sexual intercourse performance. In certain cases, it is also prescribed for pulmonary arterial hypertension under medical supervision. While off-label uses exist, they should only be pursued with explicit guidance from a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Sildenafil comes in tablet form, with dosages ranging from 25mg to 200mg. The appropriate dose depends on several factors, including the severity of ED, age, kidney and liver function, and other co-existing medical conditions. It is crucial to adhere to prescribed instructions and not self-adjust the dose without a doctor\’s guidance.
How to Take It Correctly Step-by-Step
Sildenafil should be taken approximately 30 minutes to an hour before sexual activity, but not more than once per day. It can be taken with or without food, though a high-fat meal may delay its onset. If a dose is missed, it should be taken when remembered but never doubled for missed doses. Store it at room temperature away from moisture and heat.

Caution is advised for those with cardiovascular disease, a history of stroke, or severe liver impairment. Pregnant or breastfeeding individuals should consult healthcare providers for advice.
