Drug Interaction Report

Limited evidence suggests that diroximel fumarate may have the potential to cause kidney damage, and using it with other medications that can also affect the kidney, such as acetaZOLAMIDE, may increase the 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. Let your doctor know if you experience signs and symptoms of kidney damage such as nausea, vomiting, loss of appetite, increased or decreased urination, sudden weight gain or loss, fluid retention, swelling, shortness of breath, muscle cramps, tiredness, weakness, dizziness, confusion, and/or irregular heart rhythm. 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.

Taking diroximel fumarate with high-fat, high-calorie meals or snacks may reduce the levels of active medication in the blood, which may make the medication less effective in treating your condition. Food may help improve the tolerability of diroximel fumarate if you are experiencing flushing or gastrointestinal side effects from the medication; however, meals or snacks should contain no more than 700 calories and no more than 30 grams of fat. In addition, you should avoid or limit the use of alcohol while being treated with diroximel fumarate.
