Interactions between your drugs

Moderate

bedaquiline berotralstat

Applies to: bedaquiline and berotralstat

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with berotralstat may increase the plasma concentrations and effects of drugs that are substrates of CYP450 3A4 and/or 2D6. The mechanism is decreased clearance due to inhibition of CYP450 3A4 and 2D6 activity by berotralstat. Berotralstat is considered a moderate inhibitor of CYP450 3A4 and 2D6. In drug interaction studies, berotralstat reportedly increased the peak plasma concentration (Cmax) and systemic exposure (AUC) of the sensitive CYP450 3A4 substrate midazolam by approximately 1.5-fold and 2.25-fold, respectively, and the CYP450 3A4 substrate amlodipine by approximately 1.5-fold and 1.75-fold, respectively. It increased the Cmax and AUC of the sensitive CYP450 2D6 substrate dextromethorphan by approximately 2.9-fold and 2.7-fold, respectively, and the CYP450 2D6 substrate desipramine by 1.7-fold and 1.9-fold, respectively. Clinical data are not available.

MANAGEMENT: Caution is advised when berotralstat is coadministered with drugs that are substrates of CYP450 3A4 and/or 2D6, particularly those with a narrow therapeutic index. Clinical and laboratory monitoring are recommended following the initiation of berotralstat, and the individual dosages of the concomitant agents adjusted as needed.

Drug and food interactions

Moderate

bedaquiline food

Applies to: bedaquiline

Food significantly increases the absorption of bedaquiline. Therefore, you should take each dose of bedaquiline with food. Taking it on an empty stomach may lead to inadequate blood levels and reduced effectiveness of the medication in treating tuberculosis. Avoid alcohol during treatment with bedaquiline, as it may increase the risk of liver damage. You should seek immediate medical attention if you develop signs and symptoms of liver damage such as fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, light colored stools, and yellowing of the skin or eyes. 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.

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.
