For erectile dysfunction, take 1 tablet 30 minutes before sexual activity. Your doctor may adjust the dose. Do not take more than one tablet a day unless prescribed by your doctor.
For an enlarged prostate, take one tablet once daily. Your doctor will determine the right dose for you.
It is important to follow your doctor's instructions. They will consider your medical history, overall health, and any other medications you may be taking. These considerations determine the right dose for you. Your doctor needs to determine if high blood pressure or heart problems prevent sexual activity.
