Complete Viagra Treatment Information
How Viagra Works for Erectile Dysfunction
Viagra contains sildenafil citrate, a PDE5 inhibitor that works by increasing blood flow to the penis during sexual arousal. It blocks the phosphodiesterase type 5 enzyme, helping to maintain erections when sexually stimulated. Importantly, Viagra does not cause automatic erections and requires sexual stimulation to be effective.
Available Dosages and Usage Guidelines
Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most patients start with 50mg, taken approximately 30-60 minutes before sexual activity. The dose may be adjusted to 25mg or 100mg based on effectiveness and any side effects experienced. Only one dose should be taken within a 24-hour period.
Eligibility and Prescription Requirements
Viagra requires a prescription following consultation with a UK-licensed healthcare professional. The clinical assessment evaluates cardiovascular health, current medications, and medical history to ensure safe treatment. Adult men aged 18 and over with erectile dysfunction may be eligible for treatment.
Important Safety Considerations
Viagra should not be used by individuals taking nitrates (such as GTN spray), those with severe heart conditions, recent heart attack or stroke, severe liver problems, or very low blood pressure. A comprehensive medical assessment helps identify any contraindications before treatment begins.
Branded vs Generic Options
EverydayMeds provides both branded Viagra (manufactured by Pfizer) and generic sildenafil options. Both contain the same active ingredient and work identically, with generic sildenafil typically offered at a lower cost. Patients can select their preferred option during the checkout process.
What to Expect from Treatment
Most men find Viagra effective when taken as prescribed. The medication may work better on an empty stomach, as fatty foods can delay its onset. Effects typically begin within 30-60 minutes and may last up to 4-6 hours, though this refers to the medication's presence in the system rather than continuous erection duration.
