Sildenafil is a medicine most people know as Viagra, or as Revatio when used for lung issues. It treats erectile dysfunction and pulmonary arterial hypertension by relaxing blood vessels to improve blood flow. This short guide tells you practical things: how it works, common doses, risks, interactions, and basic buying tips.
Sildenafil starts working in about 30 to 60 minutes for most people and can last three to five hours. Food slows it down, especially high-fat meals, so taking it on a lighter stomach helps timing. Alcohol and heavy drinking reduce effectiveness and add side effect risk, so skip the binge before a dose.
For erectile dysfunction the usual starting dose is 50 mg, taken as needed about an hour before sex. Doctors may suggest 25 mg or 100 mg depending on age, health, and other drugs. For pulmonary arterial hypertension the dose and schedule are different, often lower and taken regularly; follow your specialist's instructions. Never take more than one dose in 24 hours unless your doctor says so.
If you have kidney or liver problems your doctor may lower the dose. Older adults often start at a lower dose too. If the drug doesn't work at first, don't double up - talk to your prescriber about adjusting the plan or trying a different treatment.
Common side effects include headache, flushing, indigestion, nasal congestion, and visual changes like a blue tint or sensitivity to light. These often fade after a few hours. Serious reactions are rare but include sudden vision loss, hearing loss, chest pain, or an erection lasting longer than four hours. Those need immediate emergency care.
The biggest safety risk is taking nitrates with sildenafil. Nitrates are found in some chest pain medications and in recreational drugs called "poppers." Combining them can cause a severe drop in blood pressure. Alpha-blockers for prostate problems can also interact, so spacing doses and medical supervision matter.
Tell your doctor about heart disease, low blood pressure, stroke history, bleeding disorders, or eye problems like retinitis pigmentosa before starting sildenafil. Also list all medicines and supplements you take to spot harmful interactions.
When buying sildenafil online, use only licensed pharmacies that require a prescription. Avoid sites that sell without a prescription or offer suspiciously low prices. Look for clear contact info, pharmacy license details, and secure payment pages. When in doubt, ask your healthcare provider for a reliable option.
Store sildenafil at room temperature away from moisture and heat. Keep it out of reach of children. If you miss a dose for regular pulmonary treatment, follow the prescription advice - don't double up later.
If you're thinking about sildenafil, a quick chat with your doctor will clear the best dose and check safety with other conditions and drugs. It works well for many people when used properly and with basic precautions. Want more details or real user experiences? Check trusted medical sites or bring notes to your appointment today.
