Sildenafil: What it treats, how to use it, and safety tips
Want a straightforward take on sildenafil? This drug is best known for treating erectile dysfunction (ED) and is also used for pulmonary arterial hypertension (PAH). It works by relaxing blood vessels so blood flows easier — that’s the simple part. Below you’ll find clear dosing rules, what to avoid, and how to stay safe if you buy it online.
How to use sildenafil
For ED, common starting doses are 25–50 mg taken about 30–60 minutes before sexual activity. Some people use 100 mg, but don’t jump to that without talking to your doctor. For PAH, the usual prescription (Revatio) is 20 mg three times a day. Don’t take it more often than prescribed.
Food matters: a heavy, high-fat meal can delay how fast sildenafil starts working. Alcohol? A drink or two usually won’t break anything, but drinking a lot makes dizziness, low blood pressure, and poor erections more likely.
Key safety points and interactions
Never take sildenafil with nitrates (like nitroglycerin) — that combo can cause dangerously low blood pressure. If you’re on nitrates for chest pain, tell your doctor. Also watch for strong CYP3A4 inhibitors such as ritonavir, ketoconazole, and some antibiotics; these raise sildenafil levels and may require a lower dose.
Alpha-blockers for prostate problems can combine with sildenafil to drop your blood pressure. If you use both, your doctor will start low and monitor you. People with severe liver or kidney disease usually need a lower dose.
Common side effects include headache, flushing, indigestion, nasal congestion, and mild visual changes (blue tint). Rare but serious events: sudden vision loss, sudden hearing loss, and priapism — seek immediate emergency care if you get a painful erection lasting more than four hours or any sudden sensory changes.
Thinking of buying sildenafil online? Treat it like any prescription medicine. Use a licensed pharmacy that asks for a valid prescription and has clear contact details. Avoid sites that sell without a prescription or offer unusually low prices — fake pills are common and risky. If you’re in doubt, check for pharmacy accreditation or ask a pharmacist for help.
Final practical tips: start with the lowest effective dose, avoid mixing with nitrates or heavy alcohol, tell doctors about all your meds, and stick to reputable pharmacies. If sildenafil doesn’t help or causes troubling side effects, go back to your clinician — there are other treatment paths worth exploring.
