Short Description
Sildenafil 50 mg Tablets are a prescription medicine used to treat erectile dysfunction in adult men. Sildenafil belongs to the PDE5 inhibitor class and helps increase blood flow to the penis in response to sexual stimulation. It is taken by mouth as needed.
What Is Sildenafil 50 mg Tablets?
Each tablet contains 50 mg of sildenafil, present as sildenafil citrate. Sildenafil is a PDE5 inhibitor, a medicine that supports the body's natural erection process.
Erectile dysfunction is the inability to achieve or maintain an erection sufficient for satisfactory sexual activity. Sildenafil does not cause an erection on its own and does not act as a treatment for the underlying cause, so sexual stimulation is required for it to work.
Uses
Sildenafil 50 mg Tablets may be prescribed to:
Sildenafil is not indicated for use in women or in anyone under 18 years of age. A healthcare professional should assess the possible causes of erectile dysfunction and your cardiovascular health before treatment. The appropriate treatment and dose should be determined by a healthcare professional.
How Does Sildenafil Work?
During sexual stimulation, nitric oxide is released in the penis, increasing levels of a chemical messenger called cGMP. This helps relax the smooth muscle and increase blood flow to the penis.
Sildenafil blocks an enzyme called PDE5, which helps maintain cGMP levels and supports an erection when sexual stimulation occurs. Sildenafil does not cause an erection without sexual stimulation.
How to Take Sildenafil
Take Sildenafil exactly as prescribed by your healthcare professional.
Sildenafil is taken as needed, usually about one hour before sexual activity. It is not a medicine to be taken every day on a regular schedule.
Swallow the tablet whole with water.
It may be taken with or without food. A heavy or fatty meal may delay the onset of action.
Do not take more than one dose in 24 hours. Your healthcare professional may adjust your dose depending on how you respond to treatment. Do not change the dose yourself.
Do not combine sildenafil with other erectile dysfunction treatments unless advised by your healthcare professional.
Do not change your dose without advice. Speak with your doctor if the medicine does not work for you.
