You should not receive this medicine if you are pregnant. Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment with this medicine and for 6 months after the last dose. Male patients with female partners should use an effective form of birth control during treatment with this medicine and for 3 months after the last dose. If you think you or your sexual partner have become pregnant while using the medicine, tell your doctor right away.

If you plan to have children, talk with your doctor before using this medicine. Some men using this medicine have become infertile (unable to have children).

Tell your doctor right away if you have chest pain or discomfort, chills, cough, difficulty with breathing, eye pain, fever, general feeling of illness, headache, sore throat, unusual tiredness or weakness, or weight gain while using this medicine. These may be symptoms of a serious condition called retinoic-acid-APL (RA-APL) or APL differentiation syndrome.

This medicine can cause serious heart rhythm problems, including arrhythmias. Your doctor will monitor you during treatment to assess for heart rhythm problems. Talk to your doctor if you have concerns about this.

This medicine may cause a brain disease called encephalopathy. It may also increase your risk for Wernicke’s encephalopathy, especially if you have vitamin B1 (thiamine) deficiency. This is more likely in patients who have been drinking alcohol for a long time, who also use a diuretic (eg, furosemide), or who have malabsorption and nutritional deficiency. Check with your doctor right away if you have blurred vision, loss of consciousness, confusion, dizziness, drowsiness, fever, hallucinations, headache, irritability, mood or mental changes, seizures, a stiff neck, unusual tiredness or weakness, or vomiting.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Using this medicine may increase your risk of getting other cancers. Talk to your doctor if you have concerns about this risk.

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.
