Feeling nervous about taking sildenafil? Plenty of people are. Here’s a direct, useful run-down of what the drug usually does, what side effects are common, and the safety points most people miss. No fluff — just practical info you can use before your next dose.
Sildenafil relaxes blood vessels in the penis to help you get and keep an erection when you’re sexually aroused. It usually starts working within 30–60 minutes. Many people notice the best effect around 1 hour after a dose, and effects can last up to 4–5 hours. That doesn’t mean you’ll be erect the whole time — sexual stimulation is still needed.
Typical starting doses for erectile dysfunction are 50 mg for most adults. Doctors often recommend 25 mg if you’re older, or if you have liver or kidney problems. The maximum dose is 100 mg in a 24-hour period. For pulmonary arterial hypertension, dosing and purpose differ, so follow your prescriber’s instructions.
Common side effects are headache, flushing, indigestion, stuffy nose, and mild dizziness. Some people see a blue tint to their vision or have blurred sight for a short time. These usually go away, but tell your doctor if they persist.
Serious but rare problems include priapism (an erection lasting more than 4 hours), sudden vision loss (possible NAION), and sudden hearing loss. If you get any of those, seek emergency care right away.
Don’t take sildenafil with nitrates (like nitroglycerin) or riociguat — the combination can dangerously lower your blood pressure. Also be careful with alpha-blockers, some antibiotics (macrolides), azole antifungals (ketoconazole, itraconazole), and HIV protease inhibitors — these can raise sildenafil levels. Grapefruit juice and strong CYP3A4 inhibitors can also increase effects and side effects.
Alcohol won’t stop sildenafil from working, but heavy drinking can reduce effectiveness and increase the chance of dizziness or fainting. Try to avoid large meals high in fat before taking sildenafil — they slow absorption and delay onset.
Practical tips: start with the dose your doctor suggests, take it about an hour before sex, and test how you react in a safe setting. Keep a list of your medications to check for interactions. If you have chest pain, fainting, or an erection that won’t go away, get medical help right away.
Got questions about dosage, interactions, or side effects? Talk to your healthcare provider — they know your medical history and can give advice that fits you. Use this guide to have a sharper conversation and make safer choices about sildenafil use.
