Need a straight answer about sildenafil? This drug is most known for treating erectile dysfunction (ED) and is also used in a different form for pulmonary arterial hypertension (PAH). Know what it does, what to watch for, and how to shop safely online without getting overwhelmed.
Sildenafil relaxes blood vessels to improve blood flow. For ED most people take 25–100 mg as needed, about 30–60 minutes before sex. Don’t take more than 100 mg in a day. For PAH the prescription and dosing differ—usually a lower dose schedule under a specialist’s care.
Common side effects are headache, flushing, nasal congestion, indigestion, and sometimes light sensitivity or blurred vision. These often pass within a few hours. Serious risks include a drop in blood pressure and priapism (a painful erection lasting more than 4 hours). If that happens, get emergency care right away.
Never mix sildenafil with nitrates (often prescribed for chest pain). That combo can cause dangerous blood pressure drops. Be cautious if you take alpha-blockers for prostate issues or certain HIV, antifungal, or antibiotic drugs—these can raise sildenafil levels. Grapefruit and grapefruit juice may increase drug levels too.
If you have heart disease, recent stroke, low blood pressure, severe liver or kidney problems, or retinal disease, talk to your doctor before taking sildenafil. Older adults often start at a lower dose to cut side effects.
Want to buy online? Follow a short checklist. First, get a valid prescription from a licensed clinician. Reputable pharmacies will ask for that. Second, check the pharmacy’s contact info, visible address, and verified reviews. Third, avoid prices that seem too good to be true—counterfeit meds are common when the price is unrealistically low.
Look for secure checkout (https), clear shipping and return policies, and batch/lot numbers on the packaging. When your pills arrive, check the packaging, expiry date, and tablet appearance. If anything looks off, don’t take them and contact the pharmacy.
Start with a lower dose if you’re unsure how you’ll react, and test it in a safe setting when you can relax. Keep a list of all medicines you take and show it to your prescriber so they can spot interactions.
