Always follow your doctor’s instructions. A typical starting dose is 50mg, taken as needed, about one hour before sexual activity. Your doctor may adjust this based on your response and individual health needs.
Do not exceed 100mg in a 24-hour period. Taking more than the recommended dose doesn’t increase effectiveness and increases the risk of side effects.
Sildenafil can interact with other medications, particularly nitrates. Inform your doctor of all medications you are currently taking, including over-the-counter drugs and supplements. This avoids potentially dangerous interactions.
Common side effects include headache, flushing, nasal congestion, and visual disturbances. These are usually mild and temporary. Severe side effects are rare but require immediate medical attention. These include chest pain, sudden vision loss, or prolonged erection (priapism).
Alcohol consumption can affect the effectiveness and increase the risk of side effects. Moderate your alcohol intake or avoid it altogether while using sildenafil.
Sildenafil is not suitable for everyone. Individuals with certain heart conditions, liver or kidney problems, or a history of stroke should avoid this medication. Discuss your medical history with your doctor before starting treatment.
Consult your physician for personalized advice and to determine the appropriate dosage and safety profile for your situation.
