Precautions
It is very important that your doctor check your progress closely while you are receiving this medicine and to see if it is working properly.
Using large doses of this medicine may cause unwanted effects. Tell your doctor right away if you have a headache, anxiety, fast, pounding, or uneven heartbeat, ringing in the ears, or tingling in the hands and feet.
Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of some tests may be affected by 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.
