Precautions

Drug information provided by: Merative, Micromedex®

It is important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests will be needed to check for unwanted effects.

Do not suddenly stop taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent worsening of your condition and reduce the risk of acute hemolysis (rapid breakdown of red blood cells). Call your doctor right away if you have confusion, dark urine, dizziness, trouble breathing, unusual tiredness or weakness, or yellow eyes or skin.

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.
