Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For phentolamine, the following should be considered:

Allergies - Tell your doctor if you have ever had any unusual or allergic reaction to phentolamine. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Older adults - Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. Although there is no specific information comparing the use of phentolamine for erectile dysfunction in the elderly, it is not expected to cause different side effects or problems in older people than it does in younger adults.

In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
