Description
Tadalafil belongs to a group of medications called phosphodiesterase type 5 inhibitors. It is used to treat erectile dysfunction (male impotence). It helps to achieve and maintain an erection sufficient for sexual activity to occur. It does this by allowing a greater flow of blood into the penis when a man taking the medication is sexually aroused. It works only with sexual stimulation and does not increase sexual desire.
Tadalafil is also used to treat symptoms of benign prostatic hyperplasia (BPH) in men with enlarged prostates. It helps to relieve symptoms such as the frequent need to urinate, painful urination, or the sensation of not completely emptying the bladder. It does this by relaxing muscles in the prostate and bladder. Tadalafil may be used to treat men who experience both erectile dysfunction and BPH.
For the treatment of erectile dysfunction:
On-demand dosing:
The usual recommended dose is 20 mg taken as needed, at least 30 minutes before sexual activity. This medication has been shown to be effective within 30 minutes of taking the tablet, and last up to 36 hours later. As the amount of time tadalafil takes to work varies from person to person, starting sexual activity at different times after taking the tablet will determine the optimal time for sexual activity. The maximum recommended amount of medication to take is one tablet a day.
Once-a-day use:
The usual recommended dose is 5 mg per day, taken at about the same time each day and regardless of when sexual activity is planned. The daily dose may be lowered by your doctor if necessary.
Tadalafil may be taken with or without food.
For the treatment of benign prostatic hyperplasia (BPH) or erectile dysfunction with BPH:
The usual recommended dose is 5 mg once daily, at about the same time each day. It may be taken with or without food.
