Viagra Dosage, Eligibility & Safety Information
How Viagra Works
Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis when sexually aroused. It does not cause automatic erections - sexual stimulation is still required. The medication typically works within 30-60 minutes and effects may last 4-6 hours, though this does not mean an erection lasts this duration.
Available Strengths & Dosing
Viagra is available in 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, which may be adjusted to 25mg or 100mg based on effectiveness and tolerability. Only one dose should be taken within 24 hours. Food, particularly fatty meals, may delay the onset of action.
Eligibility Requirements
Viagra is suitable for adult men over 18 experiencing erectile dysfunction. All patients must complete a clinical assessment with a UK-licensed prescriber who will evaluate cardiovascular health, current medications, and medical history. The medication is not suitable for women or those under 18.
Important Safety Considerations
Viagra must not be taken with nitrates (such as GTN spray or isosorbide), as this combination can cause dangerous blood pressure drops. It is also contraindicated in men with severe heart disease, recent heart attack or stroke, severe liver problems, or very low blood pressure. Always inform your prescriber of all current medications and health conditions.
Branded vs Generic Options
EverydayMeds offers both Viagra (the original branded version) and sildenafil (the generic equivalent). Both contain identical active ingredients and work in the same way, with the generic option typically being more cost-effective whilst maintaining the same clinical efficacy and safety profile.
