Sildenafil — what it does and who it helps
Sildenafil is a medicine most people know for treating erectile dysfunction (ED). It’s also used for pulmonary arterial hypertension under different brand names and dosages. If you’re thinking about sildenafil, this quick guide tells you how it works, common side effects, who should avoid it, and tips for buying it safely online.
How sildenafil works and typical dosing
Sildenafil relaxes blood vessels so blood flows more easily to certain areas of the body. For ED, you usually take it 30–60 minutes before sexual activity. Doses commonly range from 25 mg to 100 mg depending on health, age, and other meds. For pulmonary arterial hypertension, doctors prescribe different, typically lower, daily dosing and monitor you more closely. Never change the dose without talking to your prescriber.
Missed dose rules depend on why you take it. For ED, it’s taken as needed. For PAH, follow the schedule your doctor gives. If you’re unsure, ask your pharmacist — they can explain timing and what to watch for.
Safety, interactions, and buying tips
There are a few safety rules you should know. Do NOT take sildenafil with nitrates (often used for chest pain). That combo can drop your blood pressure dangerously. Tell your doctor if you take alpha-blockers, some HIV or antifungal meds, or certain heart medicines — they can change how long sildenafil stays in your body.
Common side effects are headache, flushing, indigestion, stuffy nose, or mild dizziness. Rare but serious issues include sudden vision or hearing loss, or a painful erection lasting more than four hours (priapism). Seek immediate medical help for those.
Thinking of buying sildenafil online? Use only licensed pharmacies. Look for a valid prescription requirement, clear contact info, and a real pharmacist you can reach. If a site sells sildenafil without asking for a prescription or offers suspiciously low prices, it’s a red flag. Fake pills can contain the wrong dose or harmful ingredients.
Generics are common and cheaper. Generic sildenafil contains the same active ingredient as brand-name versions. Compare prices, check shipping rules for your country, and read pharmacy reviews from independent sources before ordering.
Other practical tips: avoid mixing sildenafil with recreational drugs like poppers (amyl nitrite) or high amounts of alcohol. Store pills in a cool, dry place away from children. If you have heart disease, low blood pressure, or recent stroke, talk to your doctor before using sildenafil.
