What It Is and How It Works
Sildenafil citrate is a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. By inhibiting the enzyme PDE5, sildenafil citrate regulates the flow of blood within the body. This allows blood vessels to relax and widen, especially in the lung and penile areas, which aids in maintaining an erection sufficient for sexual activity.
Indications / Uses
The primary indication for sildenafil is the treatment of erectile dysfunction. It is also used for pulmonary arterial hypertension under specific brand names in different formulations. Off-label uses, while less common, may include treatment for certain vascular conditions under specialist supervision.
Dosage Forms and Typical Dosing Considerations
Sildenafil is commonly available as oral tablets in 25 mg, 50 mg, and 100 mg strengths. The 200 mg dose is notably higher and not typically recommended without thorough clinical evaluation and indication. Patients should always adhere to the dosing advice provided by their healthcare provider, based on individual health status, age, concurrent medications, and liver or kidney function.
How to Take It Correctly Step-by-Step
Sildenafil should be taken approximately 30 to 60 minutes before intended sexual activity, but not more than once daily. It can be taken with or without food, but high-fat meals may delay its onset of action. If a dose is missed in a non-daily regimen, consult with a healthcare provider before doubling up or adjusting the timing. Store at room temperature away from moisture and heat.
Side Effects Common to Serious
Common Side Effects
These can include headaches, flushing, indigestion, nasal congestion, dizziness, and visual disturbances.
Less Common Side Effects

Serious or Rare Side Effects
Seek immediate medical attention if experiencing symptoms such as sudden vision loss, hearing loss, chest pain, or an erection lasting more than four hours (priapism).
Contraindications & Precautions
Sildenafil should not be used in individuals with known allergies to the drug or those taking nitrates or guanylate cyclase stimulators due to the risk of severe hypotension. Caution is advised in patients with cardiovascular disease, liver or kidney issues, retinitis pigmentosa, or a history of stroke or heart attack. Pregnant or breastfeeding women should avoid use, as there is limited data on safety.
Drug, Food, and Supplement Interactions
Sildenafil can interact with nitrate medications used for chest pain, causing dangerous decreases in blood pressure. Alcohol should also be limited. It is important to disclose all medications, both prescription and over-the-counter, as well as any herbal supplements to ensure comprehensive safety screening.
