Your Essential Viagra Questions Answered
What is Viagra and How Does It Work?
Viagra is the brand name for sildenafil citrate, manufactured by Pfizer. It belongs to a class of medicines called PDE5 inhibitors, which work by increasing blood flow to the penis when you're sexually aroused. Viagra doesn't cause automatic erections - sexual stimulation is still required. The medicine typically works within 30-60 minutes of taking it, with effects potentially lasting 4-6 hours.
Viagra vs Generic Sildenafil - What's the Difference?
Both contain the same active ingredient (sildenafil citrate) and work identically. The main difference is price - generic sildenafil is typically more affordable than branded Viagra. At EverydayMeds, you can choose between branded Viagra or generic sildenafil during checkout, depending on your preference and budget.
Available Dosages and How to Take Viagra
Viagra is available in 25mg, 50mg, and 100mg tablets. Most men start with 50mg, which can be adjusted up to 100mg or down to 25mg based on effectiveness and tolerance. Take only one tablet per 24-hour period, approximately 30-60 minutes before sexual activity. Avoid taking with large or fatty meals as this may delay effectiveness.
Who Can Take Viagra in the UK?
Viagra is suitable for adult men (18+) with erectile dysfunction who complete a clinical assessment. You'll need a prescription following consultation with a UK-licensed prescriber. The assessment evaluates your cardiovascular health, current medications, and medical history to ensure Viagra is safe for you.
Important Safety Information and Contraindications
Viagra is not suitable if you take nitrates (GTN spray, isosorbide), have severe heart disease, recent heart attack or stroke, severe liver problems, or very low blood pressure. Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. Seek immediate medical attention if you experience an erection lasting over 4 hours or sudden vision/hearing changes.
