Sildenafil Citrate

The active ingredient in Viagra and generic erectile dysfunction (ED) tablets is sildenafil citrate. It helps increase blood flow to the penis when you're sexually aroused, making it easier to get and keep an erection. People use low-dose sildenafil for pulmonary arterial hypertension in specialist care.

How it works is straightforward: sildenafil blocks an enzyme called PDE5, which relaxes blood vessels in the penis. That relaxation lets blood enter more easily during sexual stimulation. It does not cause automatic erections — stimulation is still needed.

Common starting doses for ED are 25 mg, 50 mg, or 100 mg taken about one hour before sex. If you have liver or kidney problems, are over 65, or take certain medicines, your doctor will likely recommend a lower dose. Never take more than one dose in 24 hours unless your prescriber says it's safe.

Side effects can include headache, flushing, nasal congestion, indigestion, and vision changes like a blue tint. Serious but rare effects are sudden hearing loss, prolonged erections (priapism), and chest pain. If you get a painful erection lasting more than four hours, seek emergency care. If you have chest pain or sudden vision or hearing loss, call emergency services.

Sildenafil interacts with nitrates found in some heart medications — that combo can dangerously drop blood pressure. It can also interact with alpha blockers, certain antibiotics, antifungals, and HIV drugs. Always tell your doctor about every prescription, over-the-counter medication, and herbal remedy you take.

Thinking about buying sildenafil online? Be cautious. Use licensed pharmacies that require a prescription and display contact information and pharmacy license details. Avoid sites offering huge discounts without asking for a prescription or those that push bulk orders without medical screening. Read reviews, check for secure payment methods, and if possible use a pharmacy tied to a real physical address.

For people in Australia and similar regions, buying from online pharmacies that ship internationally is common, but verify credentials and shipping rules. Telehealth services that pair a short online consult with a licensed pharmacy can be a safer route than anonymous sellers.

Storage is simple: keep tablets in their original pack at room temperature away from moisture and heat. Keep all medicines out of reach of children.

If you’re unsure whether sildenafil is right for you, ask your GP or a sexual health clinic. They can suggest alternatives like tadalafil (Cialis) or lifestyle steps that improve ED — quitting smoking, losing weight, and managing diabetes or high blood pressure.

Remember: self-medicating can hide serious health issues. Erectile troubles sometimes point to diabetes, heart disease, or low testosterone. A quick medical check can protect your health and make treatment work better. If cost is a problem, look at prescription savings apps, patient assistance programs, or generics. Cheap pills from unknown sellers are rarely worth the risk. Ask questions. Stay safe today.
