Drug Interactions between ozanimod and ruxolitinib topical

Consumer information for this interaction is not currently available.

MONITOR CLOSELY: Smoking during treatment with topical ruxolitinib may increase the risk of major adverse cardiovascular events (MACE) and the risk of developing malignancies, including lymphomas. During clinical trials, patients who were current or past smokers and received oral Janus Kinase (JAK) inhibitors to treat inflammatory conditions had an additional increased risk of overall malignancies. Additionally, oral JAK inhibitors reportedly increase patients' risk of MACE, including cardiovascular death, myocardial infarction, and stroke, particularly in patients who are current or past smokers or patients with other cardiovascular risk factors.

MANAGEMENT: The potential risks and benefits of topical ruxolitinib should be carefully weighed prior to initiating therapy, particularly in patients with cardiovascular risk factors, as well as those with a history of malignancy, those who develop a malignancy while on treatment, and/or patients who are current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and the steps to take if they occur. The manufacturer recommends discontinuing topical ruxolitinib in patients who have experienced a myocardial infarction or stroke.

Ozanimod may be taken with or without food. While there is no need to strictly avoid most foods and beverages that contain tyramine (usually aged, fermented, cured, smoked, or pickled foods such as air-dried and fermented meats or fish, aged cheeses, most soybean products, yeast extracts, red wine, beer, and sauerkraut) during treatment with ozanimod, certain foods such as some of the aged cheeses (for example, Boursault, Liederkrantz, Mycella, and Stilton) and pickled herring may contain very high amounts of tyramine and should generally be avoided if possible. Consumption of very high levels of tyramine (greater than 150 mg) while on ozanimod treatment may lead to dangerous increases in your blood pressure, a condition known as hypertensive crisis. Talk to your doctor or pharmacist if you are uncertain about what foods, if any, to avoid. You should seek immediate medical attention if you experience sudden and severe headache, blurred vision, confusion, seizures, chest pain, nausea or vomiting, sudden numbness or weakness (especially on one side of the body), speech difficulties, fever, sweating, lightheadedness, and/or fainting during treatment with ozanimod, as these may be signs and symptoms of a hypertensive crisis. 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.
