How Sildenafil Works and Treatment Information
Understanding Sildenafil Tablets
Sildenafil is a PDE5 inhibitor that works by blocking the phosphodiesterase type 5 enzyme, which increases blood flow to the penis during sexual arousal. It's important to understand that sildenafil does not cause automatic erections - sexual stimulation is still required for the medication to be effective.
Dosage and Administration
Sildenafil tablets are available in three strengths: 25mg, 50mg, and 100mg. Most patients start with the 50mg dose, which can be adjusted based on effectiveness and tolerability. The medication should be taken 30-60 minutes before sexual activity, with a maximum of one dose per 24-hour period. Fatty meals may delay the onset of action, so consider taking on an empty stomach for faster results.
Who Can Take Sildenafil
Sildenafil is suitable for adult men over 18 experiencing erectile dysfunction. However, it requires a prescription following consultation with a UK-licensed prescriber who will assess your cardiovascular health, current medications, and medical history. The treatment is not suitable for women or those under 18 years of age.
Important Safety Considerations
Sildenafil should never be taken with nitrates (such as GTN spray or isosorbide), as this combination can cause dangerous drops in blood pressure. It's also contraindicated in men with severe heart disease, recent heart attack or stroke within six months, severe liver impairment, or very low blood pressure. Always disclose all medications and health conditions during your consultation.
Choosing Between Branded and Generic
At EverydayMeds, patients can choose between sildenafil (generic) and Viagra (branded) at checkout. Both contain identical active ingredients and work in exactly the same way - the main difference is cost, with generic sildenafil offering significant savings while maintaining the same clinical effectiveness and safety profile as the branded version.
