Sildenafil Usage
Sildenafil is used to treat erectile dysfunction in men. It works by relaxing the muscles of your penis, allowing you to have stronger and longer erections.
Sildenafil can be taken with or without food. If you take sildenafil with a meal, it will not work as well because the food may delay the absorption of sildenafil into your body. You should not drink alcohol while taking sildenafil because this may increase your chance of getting side effects such as dizziness or nausea (feeling sick).
Sildenafil Dosage
The recommended dosage of sildenafil depends on the condition being treated. The dosage is different for men and women, children, elderly people and those with cardiovascular disease.
- For men: 2 mg orally or 5 mg per rectum once daily as needed for erectile dysfunction (ED) before sexual activity or up to 1 hour after sexual activity and then every 4 hours as needed. If you take more than one dose at once, wait at least 15 minutes before taking another dose of this drug.
- For women: 100 mg orally or 50 mg per rectum once daily as needed for ED before sexual activity or up to 1 hour after sexual activity and then every 4 hours as needed.
The doctor will tell you how much medicine to take depending on your medical condition and other factors such as whether it’s a first time treatment.
