Precautions

Drug information provided by: Merative, Micromedex®

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.

Do not use this medicine if you are taking ketoconazole (Nizoral®), itraconazole (Sporanox®), or ritonavir (Norvir®).

Dizziness, lightheadedness, or fainting may occur after you use this medicine, especially when you get up from a lying or sitting position. Getting up slowly may help lessen this problem. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.

This medicine may cause some people to become dizzy or less alert than they are normally. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Tell your eye doctor (ophthalmologist) that you have used or are using this medicine before cataract surgery or any other eye procedure. This medicine may cause a serious eye problem called Intraoperative Floppy Iris Syndrome (IFIS).

Call your doctor right away if you experience a prolonged erection. This is an extremely rare side effect, but if it goes untreated, can result in permanent erectile dysfunction (impotence).

Check with your doctor right away if you have arm, back or jaw pain, chest pain or discomfort, chest tightness or heaviness, fast or irregular heartbeat, nausea, or sweating.

Benign prostatic hyperplasia can have the same symptoms as prostate cancer. They may also often occur together. Your doctor may test for the presence of the cancer before you start using this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
