What It Is and How It Works
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the enzyme PDE5, which results in the relaxation of smooth muscles and dilation of blood vessels—especially in the penis. This physiological change facilitates increased blood flow, which is necessary for achieving and maintaining an erection during sexual arousal. While sildenafil aids in erection, it is not an aphrodisiac and requires sexual stimulation to be effective.
Indications / Uses
Sildenafil is primarily indicated for the treatment of erectile dysfunction. This condition may arise from psychological, lifestyle-related, or physical factors. While sildenafil 50mg and 100mg are more commonly prescribed, the 200mg dose might be considered for certain severe cases where lower doses have not been effective. However, this higher dose should be used only under strict medical supervision due to the increased risk of side effects.
Dosage Forms and Typical Dosing Considerations
Sildenafil is available in oral tablet forms of 25mg, 50mg, 100mg, and 200mg strengths. The typical starting dose recommended is 50mg taken as needed, approximately one hour before sexual activity. The dose could be adjusted based on effectiveness and tolerance, but the maximum recommended dose is generally 100mg. The 200mg dose is not an official recommendation for new users and should only be considered under a healthcare provider\’s guidance. Factors such as age, liver or kidney function, and concomitant use of other medications play a significant role in determining the appropriate dose.
How to Take It Correctly
Take sildenafil as directed by your healthcare provider. It is typically ingested orally with water, about an hour before planned sexual activity. It can be taken with or without food, though high-fat meals may delay its onset. Do not take more than one dose per day. If a dose is missed for daily treatment schedules, skip the missed dose if it\’s near the time of your next dose. Do not double doses to catch up. Store the tablets at room temperature, away from moisture and heat.

Contraindications & Precautions
Sildenafil should not be used by individuals with a known hypersensitivity to the ingredient or related compounds. It is contraindicated in patients using nitrates, often prescribed for chest pain, as this combination can lead to a dangerous drop in blood pressure. Caution is advised for those with cardiovascular diseases, kidney disease, liver impairment, or retinitis pigmentosa. Pregnant or breastfeeding women should discuss potential risks and benefits with their healthcare provider. Sildenafil is not typically recommended for use in children or adolescents.
Drug, Food, and Supplement Interactions
Sildenafil can interact with various medications. The combination with nitrates is especially dangerous. Additionally, drugs such as certain antibiotics, antifungals, medications called alpha-blockers, and other ED treatments can potentiate effects. Grapefruit and grapefruit juice may increase sildenafil levels in the bloodstream and should be avoided. Patients should provide a full list of medications and supplements they use to their healthcare provider.
