How Sildenafil Works

Sildenafil inhibits PDE5 (phosphodiesterase type 5), which increases cGMP in penile smooth muscle, relaxes blood vessels and increases blood flow — producing an erection in response to sexual stimulation. It does not cause an erection without stimulation.

How to Take Sildenafil 100mg

Take 30–60 minutes before sexual activity. Do not take more than one dose in 24 hours. Avoid high-fat meals before taking — they delay absorption. Avoid grapefruit juice.

Side Effects

Headache, flushing, indigestion, nasal congestion, dizziness, visual disturbances (blue tinge), back pain. Serious: sudden vision loss (NAION — rare), sudden hearing loss, priapism (painful erection lasting more than 4 hours — medical emergency), severe hypotension with nitrates.

Warnings

• Never take with nitrates (GTN spray, isosorbide) — severe, potentially fatal drop in blood pressure.
• Avoid if recently had a heart attack or stroke, or have severe heart or liver disease.
• Use with caution with alpha-blockers (e.g. tamsulosin) — hypotension risk.
• Priapism: if erection lasts more than 4 hours, seek emergency medical help immediately.
