When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.
Viagra is available in three main strengths: 25mg, 50mg, and 100mg tablets. Each contains the active ingredient sildenafil citrate, which belongs to a class of medicines called PDE5 inhibitors. These work by increasing blood flow to the penis when sexually aroused, helping men achieve and maintain erections suitable for sexual activity.
Most men begin treatment with the 50mg strength, which provides an effective balance between therapeutic benefit and tolerability. This dose typically works within 30-60 minutes of taking and can remain effective for 4-6 hours. However, this doesn't mean an erection will last this long - sexual stimulation is still required for the medication to work.
Your prescriber may recommend starting with 25mg if you're over 65, have liver or kidney problems, or take certain other medications that could interact with sildenafil. This lower dose reduces the likelihood of side effects while still providing therapeutic benefit for many men.
If the standard 50mg dose doesn't provide sufficient improvement in erectile function, your dose may be increased to 100mg - the maximum recommended strength. This should only be done following consultation with a healthcare professional who can assess whether the increase is appropriate based on your response to treatment and any side effects experienced.
Conversely, if you experience bothersome side effects such as headaches, flushing, or dizziness with the 50mg dose, reducing to 25mg may provide a better balance between effectiveness and comfort.
EverydayMeds offers both branded Viagra and generic sildenafil options. Both contain exactly the same active ingredient in identical strengths, undergo the same rigorous quality testing, and work in the same way. The main difference lies in cost - generic sildenafil typically offers significant savings compared to the branded version.
Many men choose generic sildenafil for this reason, particularly for ongoing treatment. Both options are available through our online consultation service, allowing you to select your preference at checkout following approval from our UK-licensed prescribers.
Regardless of which strength you're prescribed, never exceed one tablet in any 24-hour period. Taking more than the recommended dose increases the risk of serious side effects, particularly dangerous drops in blood pressure. Always take your medication exactly as prescribed and inform your healthcare provider if you feel your current dose isn't working effectively.
Fatty meals can delay the onset of action, so consider taking your medication on an empty stomach or after a light meal for optimal effectiveness. Alcohol should be limited as it can increase the risk of side effects and may impair your ability to achieve an erection.
It's one of the most common conditions we treat, and one of the most treatable.
