What is Cenforce 100mg?
Cenforce 100mg is an erectile dysfunction (ED) medicine containing sildenafil citrate—the same active ingredient as Viagra®. It increases penile blood flow during sexual stimulation to help achieve and maintain an erection.
Composition: Each film-coated tablet contains sildenafil citrate equivalent to sildenafil 100 mg; excipients q.s.
Form: Oral, film-coated tablets.
Intended users: Adult men 18+ with ED after medical evaluation.
How it works
Sildenafil inhibits PDE-5, preserving cGMP in penile tissue. This relaxes smooth muscle and increases blood flow when sexual stimulation is present.

Yes. Cenforce contains sildenafil, the same active ingredient as Viagra®. Therapeutically equivalent at equal doses.
How long before it works, and how long does it last?
Usually 30–60 minutes to start working; lasts ~4–6 hours. Heavy meals can slow the start.
Can I take it daily?
Sildenafil is typically as-needed, no more than once per day. For frequent use, a clinician may consider tadalafil daily (2.5–5 mg).
Can I drink alcohol?
