Sildenafil citrate is the active pharmaceutical ingredient in generic Viagra. It functions by inhibiting an enzyme called phosphodiesterase-5 (PDE5).
This inhibition increases blood flow to the penis, facilitating an erection. The effect is triggered by sexual stimulation; sildenafil citrate doesn’t cause erections independently.
Dosage varies depending on individual needs and response. Always consult a doctor before starting any medication.
Common side effects include headache, flushing, and nasal congestion. Serious side effects are rare but require immediate medical attention.
Sildenafil citrate interacts with some medications, notably nitrates. Inform your doctor about all medications you are taking to avoid dangerous interactions.
