Zenegra (sildenafil Citrate) relaxes muscles and increases blood flow to particular areas of the body. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor. It works by helping to increase blood flow into the penis during sexual stimulation. This helps you to achieve and maintain an erection. Zenegra is used to treat erectile dysfunction (impotence) in men.
Use Zenegra as directed by your doctor. Check the label on the medicine for exact dosing instructions. An extra patient leaflet is available with sildenafil. Talk to your pharmacist if you have questions about this information.
Take sildenafil by mouth with or without food. Sildenafil may not work as quickly if you take it with a high-fat meal. Sildenafil is usually taken about 1 hour before sexual activity; however, it may be taken anywhere from 4 hours to a half hour before sexual activity. Talk with your doctor about the best way to take sildenafil.
Do NOT take more than the recommended dose or take it more often than once daily, or as directed by your doctor. If you miss a dose of sildenafil and you still intend to engage in sexual activity, take it as soon as you remember. Continue to take it as directed by your doctor.
