Clear Start Assessment

Sildenafil Tablets, also known by the brand name Viagra, are a trusted and widely used treatment for erectile dysfunction (ED) in adult men. ED is the inability to achieve or maintain an erection sufficient for sexual performance. Sildenafil belongs to a group of medicines called PDE5 inhibitors and is prescribed to help improve erectile response by enhancing blood flow to the penis. It is available in various strengths and as both branded (Viagra) and generic formulations.

How It Works

Sildenafil works by blocking the action of phosphodiesterase type 5 (PDE5), an enzyme that breaks down cGMP – a chemical that helps relax the smooth muscle in the penis. When sexually aroused, this relaxation allows increased blood flow, producing and maintaining an erection. Sildenafil does not cause an erection without sexual stimulation. It typically starts to work within 30 to 60 minutes and can remain effective for up to 6 hours.

Why Choose Sildenafil Tablets

Sildenafil Tablets for erectile dysfunction are among the most well-known and effective treatments available. They are often the first-choice option for men seeking support with ED, with extensive research confirming their safety and success. Sildenafil is available in several strengths, including 25mg, 50mg, and 100mg, to match varying patient needs. The generic version provides the same active ingredient as Viagra at a more affordable price.

Pharmacist-supplied Sildenafil (Viagra Connect) offers convenient access without a prescription for eligible men. It is well tolerated, reversible, and can significantly improve confidence, sexual performance, and overall quality of life.

Important Note

Do not take more than one dose in 24 hours. Sildenafil is not suitable for everyone and may not be appropriate for those with heart problems, low blood pressure, or who take nitrate medications. It should not be used by women or individuals under 18. Always follow medical advice and store tablets below 25°C in original packaging.

  • Sildenafil usually takes between 30 minutes to 1 hour to start working. However, it won’t cause an erection on its own—you still need to be sexually aroused for it to be effective. Its effects can last for up to 4 hours.

  • You can drink a small amount of alcohol, but it’s best to limit how much you have. Drinking too much can make it harder to get or keep an erection and may also increase the risk of side effects like dizziness or low blood pressure.

  • Yes, you can take it with or without food. But if you’ve had a large or high-fat meal, it might take longer to start working. For quicker results, try to avoid heavy meals beforehand.

  • You should never take more than one Sildenafil tablet in 24 hours. Taking too much can increase your risk of side effects like headaches, dizziness, or a prolonged erection. If you’ve taken more than recommended, speak to a doctor straight away.

  • Sildenafil works for most men, but not everyone will get the same results. It may not work the first time, and some men might need to try it a few times before seeing the full effect. If it still doesn’t help, speak to your GP—they may suggest a different approach or dose.
