Avoid use of strong and moderate CYP3A4 inducers with SIRTURO. ( 7.1 ) Closely monitor patient safety (e.g., liver function) when SIRTURO is coadministered with CYP3A4 inhibitors. ( 5.4 , 7.1 ) 7.1 Effect of Other Drugs on SIRTURO Strong and Moderate CYP3A4 Inducers Coadministration of SIRTURO with moderate or strong CYP3A4 inducers may decrease systemic exposure of bedaquiline. Avoid coadministration of SIRTURO with strong or moderate CYP3A4 inducers [see Clinical Pharmacology (12.3) ] . CYP3A4 Inhibitors Coadministration of SIRTURO with CYP3A4 inhibitors increases the systemic exposure of bedaquiline which may increase the risk of adverse reactions. …

A mortality imbalance was seen in clinical trials in SIRTURO-treated patients with pulmonary TB due to Mycobacterium tuberculosis resistant to at least rifampin. ( 5.2 ) Hepatotoxicity may occur with use of SIRTURO. Monitor liver-related laboratory tests. Discontinue SIRTURO if evidence of liver injury occurs. ( 5.4 ) 5.1 QTc Prolongation SIRTURO prolongs the QTc interval [see Clinical Pharmacology (12.2) ] . Use with drugs that prolong the QTc interval may cause additive QTc prolongation [see Adverse Reactions (6) ] . …

The following serious adverse reactions are discussed elsewhere in the labeling: QTc Prolongation [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.2) ] Mortality Imbalance in Clinical Trials [see Warnings and Precautions (5.2) ] Hepatotoxicity [see Warnings and Precautions (5.4) ] Drug Interactions [see Warnings and Precautions (5.5) ] The most common adverse reactions reported in 10% or more adult patients treated with SIRTURO in Study 1 were nausea, arthralgia, headache, hemoptysis and chest pain. …

8.1 Pregnancy Risk Summary Available data from published literature of SIRTURO use in pregnant women are insufficient to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are risks associated with active TB during pregnancy (see Clinical Considerations ) . …

There is no experience with the treatment of acute overdose with SIRTURO. Take general measures to support basic vital functions including monitoring of vital signs and ECG (QTc interval) in case of deliberate or accidental overdose. It is advisable to contact a poison control center to obtain the latest recommendations for the management of an overdose. Since bedaquiline is highly protein-bound, dialysis is not likely to significantly remove bedaquiline from plasma.
