Precautions

Drug information provided by: Micromedex

It is very important that your doctor check your progress at regular visits for any unwanted effects that may be caused by this medicine.

Do not use this medicine if you are also taking clarithromycin (Biaxin®), ketoconazole (Nizoral®), itraconazole (Sporanox®), or ritonavir (Norvir®). Using these medicines together may cause serious unwanted effects.

Dizziness, lightheadedness, or fainting may occur after you take 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. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert.

If you plan to have cataract surgery, tell your eye doctor (ophthalmologist) that you are taking this medicine. A serious eye problem called Intraoperative Floppy Iris Syndrome (IFIS) has occurred in some patients who were taking this medicine or who had recently taken this medicine when they had cataract surgery.

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.
