About
What is Viagra?
Active ingredient: Sildenafil · Dosages: 25 / 50 / 100 mg on demand
Sildenafil is a phosphodiesterase-5 (PDE5) inhibitor. It relaxes smooth muscle in the penile blood vessels, facilitating an erection in response to sexual stimulation — it does not cause spontaneous erections or change desire.
It's taken on demand, 30 to 60 minutes before sexual activity; high-fat meals can delay onset. The doctor prescribes the appropriate dose after reviewing your cardiovascular health, current medication and contraindications.
How it works in the body
By inhibiting the PDE5 enzyme, sildenafil improves blood flow to the penis when there is sexual stimulation. Its effect starts within 30–60 minutes and lasts around 4–6 hours.

How to take it.
On demand, before sexual activity. The doctor sets your dose and reviews it with you if the response or tolerance isn't right.
- Take it 30–60 minutes before sexual activity
- Avoid heavy, high-fat meals right before — they delay onset
- Never combine with nitrates
- Message your doctor to adjust the dose if needed

These are typical steps only. Your doctor adjusts the plan to how you respond and tolerate it — and you can message them at any point.
Safety first
Safety, in full.
Viagra is an effective medicine — and like any medicine it carries risks. Your doctor screens for all of this before prescribing. Here's the honest picture, not just reassurance.
Prescribed for adult men with erectile dysfunction. Taken about 30–60 minutes before sexual activity.
- Standard starting dose is 50 mg taken on demand, no more than once per day.
- Effect lasts up to 4 hours; sexual stimulation is still required for the medicine to work.
- A heavy or fatty meal can delay onset — taking it on a lighter stomach gives a more predictable response.
Who should not take it
- You take any nitrate medicine (for chest pain / angina) or amyl-nitrite recreational drugs (“poppers”) — combination can cause life-threatening blood-pressure drops.
- You take riociguat (for pulmonary hypertension) or any other guanylate-cyclase stimulator.
- Recent heart attack, stroke or unstable angina in the last 6 months.
- Severe liver impairment, severe low blood pressure, or known hereditary degenerative retinal disorders.
- You have ever had non-arteritic ischaemic optic neuropathy (NAION).

Discreet from start to finish. The questionnaire was thorough and the doctor adjusted my dose after feedback.
