Edit list (add/remove drugs)

Interactions between your drugs

Moderate

deferasirox tofacitinib

Applies to: Exjade (deferasirox) and tofacitinib

Deferasirox may reduce the blood levels and effects of tofacitinib. Contact your doctor if your symptoms worsen or your condition changes during treatment with these medications. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. 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.

Drug and food interactions

Moderate

deferasirox food

Applies to: Exjade (deferasirox)

You may experience reduced absorption of deferasirox in the presence of food. Take deferasirox on an empty stomach 30 minutes before eating preferably at the same time everyday unless otherwise directed by your doctor. This will make it easier for your body to absorb the medication. The tablets should not be chewed or swallowed whole. The tablets should first be completely dispersed in water, orange juice, or apple juice, and the resulting suspension drunk immediately. After swallowing the suspension any residue should be resuspended in a small volume of the liquid and swallowed.

Moderate

tofacitinib food

Applies to: tofacitinib

Consumer information for this interaction is not currently available.

MONITOR: Grapefruit juice may increase the plasma concentrations of tofacitinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. The extent and clinical significance are unknown. Moreover, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability.

MANAGEMENT: Until more information is available, some authorities recommend avoiding consumption of grapefruit juice during tofacitinib therapy (Canada). Patients receiving tofacitinib therapy who ingest grapefruits or grapefruit juice should be monitored for adverse effects and undue fluctuations in plasma drug levels.

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.
