Sildenafil is a widely used medicine for erectile dysfunction and certain types of pulmonary hypertension. Many men know it by brand names like Viagra, but the generic works the same and often costs less. You take it when you expect sexual activity — usually 30 to 60 minutes before sex — and it helps blood flow into the penis so you can get and keep an erection when you’re sexually stimulated.
Sildenafil blocks an enzyme called PDE5. That lets blood vessels in the penis relax and fill faster during arousal. Typical doses for erectile dysfunction are 25 mg, 50 mg, or 100 mg. Start low if you’re older, on other meds, or have health issues; doctors often begin at 25 or 50 mg. For pulmonary arterial hypertension, doses and schedules differ — that’s managed by a specialist.
Don’t mix sildenafil with nitrates (nitroglycerin, isosorbide) — the combo can drop blood pressure to dangerous levels. Be cautious with alpha-blockers, certain antifungals, HIV drugs, and grapefruit juice; these can raise sildenafil levels. Common side effects include headache, flushing, stuffy nose, and upset stomach. Rare but serious issues are sudden vision loss, hearing loss, or erections lasting more than four hours (priapism). Seek emergency care for those.
Before you use sildenafil, tell your doctor about heart disease, low blood pressure, stroke history, severe liver or kidney problems, or if you take blood pressure meds. If you’re on anticoagulants or have diabetes, your doctor will advise a safe dose. Women should not take sildenafil for sexual dysfunction unless prescribed and monitored — dosing and effects differ.
Practical tips for real life: Avoid heavy alcohol — it dulls response and raises side effects. Don't take two doses in one day unless a doctor says so. If one brand or strength doesn’t work, talk to your healthcare provider before trying another. If cost is a barrier, generic sildenafil is widely available and reliable when bought from licensed pharmacies.
Buying online safely: Pick pharmacies that require a prescription and show real contact details. Check reviews and verifiable licensing. Avoid sites that offer large quantities without asking questions; that’s a red flag. If you’re buying internationally, consider shipping times, local laws, and customs issues.
When to call a doctor: If you get chest pain, severe dizziness, fainting, sudden vision or hearing loss, or an erection lasting over four hours, get immediate help. For ongoing side effects or poor response, schedule a visit to review dosage and other options.
This is practical straightforward info, not personal medical advice. Talk with your healthcare provider to find the safest, most effective choice for your situation.
Timing and food matter. A high-fat meal can delay sildenafil’s start by an hour or more, so take it on a lighter stomach for faster action. If sildenafil doesn’t help after several tries, other PDE5 inhibitors like tadalafil or vardenafil may work better for you; they differ in duration and side effects. Discuss options with your clinician. Keep records of benefits.
