Viagra Treatment: Dosages and Clinical Information
How Viagra Works
Viagra contains sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When sexually aroused, it helps increase blood flow to the penis by blocking the enzyme phosphodiesterase type 5. This medication does not cause automatic erections - sexual stimulation is still required for effectiveness.
Available Dosages and Usage
Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately 30-60 minutes before sexual activity. Depending on effectiveness and tolerability, your prescriber may adjust this to 25mg or increase to 100mg. Only one dose should be taken within a 24-hour period. Food, particularly fatty meals, may delay the medication's onset.
Branded vs Generic Options
EverydayMeds offers both Viagra (the original branded version by Pfizer) and sildenafil (the generic equivalent). Both contain the same active ingredient and work identically, but generic sildenafil typically costs less whilst maintaining the same clinical effectiveness. Patients can choose their preferred option during the checkout process.
Who Can Take Viagra
Viagra is suitable for adult men aged 18 and over experiencing erectile dysfunction. Before prescribing, UK-licensed prescribers conduct a clinical assessment evaluating cardiovascular health, current medications, and medical history. This ensures the treatment is safe and appropriate for each individual patient.
Important Safety Considerations
Viagra cannot be taken with certain medications, particularly nitrates used for chest pain (such as GTN spray or isosorbide tablets), as this combination can cause dangerous drops in blood pressure. It's also unsuitable for men with severe heart conditions, recent heart attacks or strokes, severe liver problems, or very low blood pressure. Always disclose all current medications and medical conditions during consultation.
