Uses

Quick Answer

Sildenafil (Viagra) is primarily used for Erectile Dysfunction (ED — mardana kamzori) in adult men. It works by increasing blood flow to the penis upon sexual stimulation — it does NOT cause erections without stimulation. At different doses (as Revatio), it is also used for Pulmonary Arterial Hypertension under specialist supervision. ABSOLUTE CONTRAINDICATION with nitrates. Requires doctor prescription.

Primary Uses at a Glance

Erectile Dysfunction (ED — Mardana Kamzori)

Sildenafil (Viagra) is the most widely prescribed treatment for Erectile Dysfunction in adult men. It inhibits PDE5, increasing cGMP in penile vascular smooth muscle, causing relaxation and increased blood flow — enabling erection in response to sexual stimulation. It does NOT work without sexual stimulation. Underlying causes of ED (cardiovascular disease, diabetes, hormonal issues, psychological factors) should be evaluated by a physician before starting sildenafil.

As prescribed by doctor — typically 50mg taken 30-60 minutes before sexual activity, not more than once daily.

Pulmonary Arterial Hypertension (PAH)

Sildenafil (as Revatio 20mg) is used for Pulmonary Arterial Hypertension — a serious condition causing high blood pressure in the pulmonary arteries. This is a specialist/cardiologist indication with entirely different dosing (20mg three times daily) from ED dosing.

Strictly as prescribed by specialist/cardiologist — 20mg TDS (three times daily). NOT the same as ED dosing.

Frequently Asked Questions

Sildenafil kin conditions mein sabse zyada effective hai?

Sildenafil is most effective for Erectile Dysfunction, especially when the cause is vascular (blood flow). It also helps in psychological ED. Underlying medical causes (diabetes, hypertension, low testosterone) must also be treated.

Kya Sildenafil doctor ke bina le sakte hain?

Absolutely not — Sildenafil is an Rx medicine. The absolute contraindication with nitrates can be fatal. Doctor evaluation assesses cardiovascular risk. Self-medication is dangerous, especially given the risk of counterfeit tablets.

Sildenafil sexual desire barhata hai?

No — sildenafil does not increase desire (libido). It only assists the physical blood flow mechanism. Sexual stimulation is necessary for it to work. Libido problems require hormonal or psychological evaluation.

Kya Sildenafil lambe arse tak use kar sakte hain?

Yes — long-term use is possible under doctor's supervision. However, underlying causes must also be treated. Regular cardiovascular check-up is important. Dose needs monitoring.

PAH mein sildenafil alag kyun hai ED se?

In PAH the dose and schedule are completely different (20mg TDS vs 25-100mg on-demand). PAH is a serious medical condition — only a specialist prescribes it. The ED dose is not used for PAH.

Brand alternatives, same-class options, and other medicines used for the same conditions as Sildenafil Tablet (Viagra).
