Drug Interaction Report

Inotersen may cause kidney problems including glomerulonephritis, which is an inflammatory condition of the kidney. Glomerulonephritis may result in kidney failure, and combining it with other medications that can also affect the kidney such as ifosfamide may increase that risk. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek immediate medical attention if you develop signs and symptoms that may suggest glomerulonephritis such as puffiness or swelling in the face, hands, or feet; new onset or worsening shortness of breath or coughing; blood in the urine or brown urine; foamy urine (protein in the urine); and decreased urination. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Do not consume grapefruit or grapefruit juice while you are receiving treatment with ifosfamide, as this may decrease the anticancer effects of ifosfamide and may increase its adverse effects on your nervous system and your kidneys. Do not use alcohol while you are receiving treatment with ifosfamide. This may increase nervous system side effects such as somnolence, dizziness, confusion, difficulty concentrating, and impairment of thinking and judgment; and may also increase nausea and vomiting. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Also, avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you.
