Interactions between your drugs

Moderate

indinavir ruxolitinib topical

Applies to: Crixivan (indinavir) and ruxolitinib topical

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with potent inhibitors of CYP450 3A4 may increase plasma concentrations (Cmax) and systemic exposure (AUC) of topical ruxolitinib, which is primarily metabolized by the isoenzyme. Following administration of ketoconazole (200 mg twice daily for four days), a potent CYP450 3A4 inhibitor, healthy subjects then received a single dose of ruxolitinib (10 mg orally). The Cmax and AUC of ruxolitinib increased 33% and 91% respectively, compared to healthy subjects receiving the oral ruxolitinib dose alone. Increased exposure to ruxolitinib may increase the risk of adverse events. However, clinical data for topical ruxolitinib are not available.

MANAGEMENT: Concomitant use of topical ruxolitinib with potent inhibitors of CYP450 3A4 should generally be avoided. It may be advisable to monitor patients for the development of adverse effects. Consultation with individual package labeling, as well as relevant institutional protocols, may be advisable for further guidance.

Drug and food interactions

Major

ruxolitinib topical food

Applies to: 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.

Moderate

indinavir food

Applies to: Crixivan (indinavir)

Large amounts of food decreases the levels of indinavir in your body. Indinavir should be taken on an empty stomach, at least 1 hour before or 2 hours after a meal. This will make it easier for your body to absorb the medication. Take indinavir with a full glass (8 ounces) of water or skim milk. You may also drink juice, coffee, or tea with this medication. Drink at least 6 glasses of water each day to prevent kidney stones while you are taking indinavir. If you prefer to take the medication with food, eat only a light meal, such as dry toast with jelly, or corn flakes with skim milk and sugar. Avoid eating a high-fat meal.

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
