IN PLAIN TERMS
What Sildenafil is, and how to get treatment
Sildenafil is a prescription tablet for erectile dysfunction, first authorised across the EU in 1998. It relaxes the blood vessels in the penis so that more blood can flow in when you are sexually aroused. It does not create arousal on its own — sexual stimulation is still needed for it to work. It is usually taken about an hour before sex, and it cannot be used together with nitrate heart medicines.
Sildenafil has been authorised for use in the EU since 13 September 1998, so a licensed doctor can prescribe it when it is clinically appropriate for you.

VERIFIED EVIDENCE
Sildenafil: evidence and regulatory guide.
WHAT IT IS
How it works
Sildenafil blocks an enzyme called PDE5 that normally ends an erection, so when a man is sexually aroused the blood vessels in the penis stay relaxed and more blood can flow in.

What the studies reported
Results are grouped by source and evidence grade so journal data and manufacturer announcements cannot be confused.
Peer-reviewed
Sildenafil Study Group (Goldstein I, Lue TF, Padma-Nathan H, Rosen RC, Steers WD, Wicker PA). Oral sildenafil in the treatment of erectile dysfunction. N Engl J Med 1998;338(20):1397-1404. doi:10.1056/NEJM199805143382001 (PMID 9580646)| DOSE OR GROUP | MEAN WEIGHT CHANGE | WEEKS |
|---|---|---|
| 100 mg | Mean score on the IIEF question about achieving erections rose from 2.0 to 4.0 out of a possible 5 | 24 |
| 25-100 mg, flexible | 69% of intercourse attempts successful vs 22% on placebo (final 4 weeks) | 12 |
| 25-100 mg, flexible | 5.9 successful attempts per month vs 1.5 on placebo | 12 |
Both studies were short (12 and 24 weeks) and relied on self-reported questionnaires and diaries, so they describe short-term effect rather than long-term outcomes.
NAMED SAFETY SIGNALS
What has been reported with Sildenafil.
Headache
Listed as very common in the EU product information — at least 1 in 10 men. In the pivotal trial, headache, flushing and dyspepsia were the most common effects, occurring in 6% to 18% of men.
Flushing

About
What is Sildenafil?
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 it helps
How it helps.
Works on demand
Taken 30–60 minutes before sex — no daily routine required.
Adjustable dose
25, 50 or 100 mg — the doctor prescribes what fits your case and tolerance.
Doctor-screened
Cardiovascular health and interactions are reviewed before any prescription.
What to expect
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
Doses your doctor can prescribe
- Available doses25 / 50 / 100 mg
- When30–60 min before activity
Your schedule is personal
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.
Sildenafil 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).
