Complete Patient Information for Viagra UK
How Does Viagra Work?
Viagra contains sildenafil citrate, a PDE5 inhibitor that blocks the phosphodiesterase type 5 enzyme. This increases blood flow to the penis when you're sexually aroused. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required. The medication typically works within 30-60 minutes of taking it, with effects lasting 4-6 hours.
Dosages and Administration
Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which can be adjusted based on effectiveness and tolerability. Take your prescribed dose 30-60 minutes before sexual activity, and never exceed one dose in 24 hours. Food, especially fatty meals, can delay how quickly the medication works.
Who Can Take Viagra?
Viagra is suitable for adult men over 18 experiencing erectile dysfunction. However, it requires a prescription following consultation with a UK-licensed prescriber. Our clinical assessment evaluates your cardiovascular health, current medications, and medical history to ensure safe treatment. The medication is not suitable for women or anyone under 18 years old.
Important Safety Information
Certain medical conditions and medications make Viagra unsuitable. Never take Viagra if you're using nitrates like GTN spray or isosorbide, as this creates a dangerous interaction. It's also contraindicated for men with severe heart disease, recent heart attack or stroke, severe liver problems, or very low blood pressure. Always disclose your complete medical history during consultation.
Viagra vs Generic Sildenafil
EverydayMeds offers both branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient (sildenafil citrate) and work identically. The main difference is cost - generic sildenafil provides the same effectiveness at a lower price point. Your choice depends on personal preference and budget considerations.
