How Viagra Works and What to Expect
Understanding Viagra's Mechanism of Action
Viagra contains sildenafil citrate, a PDE5 inhibitor that blocks the phosphodiesterase type 5 enzyme. This action increases blood flow to the penis during sexual arousal, helping men with erectile dysfunction achieve and maintain erections. It's important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.
What Viagra Will Do: Expected Effects and Timeline
Most men can expect Viagra to work within 30-60 minutes of taking the tablet. The effects typically last 4-6 hours, though this doesn't mean an erection will persist for this duration. During this window, men may find it easier to achieve and maintain erections when sexually aroused. The medication's effectiveness can be influenced by factors such as food intake, with fatty meals potentially delaying onset.
Viagra vs Tadalafil: Key Differences
When comparing what Viagra will do versus tadalafil, the main differences lie in duration and timing. Whilst Viagra typically lasts 4-6 hours, tadalafil can remain effective for up to 36 hours. Viagra generally works faster (30-60 minutes) compared to tadalafil (30-120 minutes). Food has less impact on tadalafil's absorption. Both medications work similarly as PDE5 inhibitors but offer different benefits depending on individual preferences and lifestyle factors.
Dosage Options and Effectiveness
Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, which can be adjusted based on effectiveness and tolerability. The maximum recommended dose is 100mg within 24 hours. At EverydayMeds, patients can choose between Viagra (branded) and sildenafil (generic) at checkout - both contain the same active ingredient, with sildenafil offering a more cost-effective option.
Who Can Benefit from Viagra Treatment
Viagra may be suitable for adult men experiencing erectile dysfunction, following a clinical assessment with a UK-licensed prescriber. The treatment is not appropriate for everyone, particularly those taking nitrate medications, with severe heart conditions, or certain other health issues. A thorough medical consultation helps determine if Viagra is the right choice and what effects you can expect.
Safety Considerations and Realistic Expectations
Understanding what Viagra will do includes recognising its limitations and safety profile. Common side effects may include headaches, facial flushing, and indigestion. The medication should not be combined with nitrate medications due to dangerous interactions. Viagra works best as part of a comprehensive approach to sexual health, and individual results may vary based on underlying health factors and the severity of erectile dysfunction.
