Viagra, a blue pill containing sildenafil citrate, is designed for men experiencing erectile dysfunction. Typically ingested an hour before sexual activity, it assists in achieving and maintaining an erection. It's important to note that Viagra does not act as an aphrodisiac; sexual arousal is still required for its efficacy.

​

Viagra comprises sildenafil citrate as the active ingredient, alongside various inactive components including microcrystalline cellulose, calcium hydrogen phosphate (anhydrous), croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide (E171), lactose, triacetin, and indigo carmine aluminum lake (E132).

​

Take this medication orally as directed by your physician, typically as needed. Sildenafil should be taken at least 30 minutes, but no more than 4 hours, before engaging in sexual activity (1 hour before being the most effective timing). Refrain from taking more than one dose per day.
