Note: Expert consultation for optimal regimen and duration of treatment is advised.
Oral: Directly observed therapy: 400 mg once daily for 2 weeks, followed by 200 mg 3 times weekly with doses spaced ≥48 hours apart; use as part of an appropriate combination regimen (Ref). Alternatively, a regimen of 200 mg once daily for 8 weeks, followed by 100 mg once daily for 18 weeks, has been studied in combination with linezolid and pretomanid (Ref).
Missed doses: 400 mg once daily for 2 weeks, followed by 200 mg 3 times weekly regimen: If a dose is missed during the first 2 weeks, do not make up the missed dose, and continue the usual dosing schedule. From week 3 onward, if a dose is missed, administer the missed dose as soon as possible, and resume the 3 times a week schedule; the total dose during a 7-day period should not exceed the recommended weekly dose of 600 mg (with ≥24 hours between doses).
Duration: Individualize based on rapidity of culture conversion, extent of disease, and patient-specific factors, including clinical response and toxicity (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Mild to moderate renal impairment: No dosage adjustment necessary.
Severe renal impairment: There are no dosage adjustments provided in the manufacturer's labeling; use with caution and monitor for adverse reactions.
End-stage renal disease (ESRD) on intermittent hemodialysis (IHD) or peritoneal dialysis (PD): There are no dosage adjustments provided in the manufacturer's labeling; use with caution and monitor for adverse reactions. Bedaquiline is highly protein bound and not likely to be removed by dialysis.

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified. Adverse reactions reported with combination therapy in adults.
>10%:
Cardiovascular: Chest pain (11%)
Gastrointestinal: Nausea (38%)
Hepatic: Increased serum transaminases (9% to 11%)
Nervous system: Headache (28%)
Neuromuscular & skeletal: Arthralgia (33%)
Respiratory: Hemoptysis (18%)
1% to 10%:
Dermatologic: Skin rash (8%)
Gastrointestinal: Anorexia (9%), increased serum amylase (3%)
Frequency not defined:
Cardiovascular: Prolonged QT interval on ECG
Hepatic: Hepatotoxicity
There are no contraindications listed in the manufacturer's labeling.
Concerns related to adverse effects:
• Hepatic effects: Increased risk of hepatic reactions; avoid alcohol intake and other known hepatotoxic drugs, especially in patients with impaired hepatic function. Test for viral hepatitis and discontinue other hepatotoxic medications if evidence of new or worsening hepatic disease occurs. Discontinue use if aminotransferase elevations are accompanied by total bilirubin elevation >2 times ULN, aminotransferase elevations are >8 times ULN, or aminotransferase elevations are >5 times ULN and continue for >2 weeks.
• Increased mortality: An increased risk of death was seen in the bedaquiline treatment group, compared to the placebo treatment group, in one placebo-controlled trial in adults. The imbalance in deaths is unexplained; no discernible pattern between death and sputum culture conversion, relapse, sensitivity to other drugs used to treat tuberculosis, HIV status, or severity of disease could be identified. In a subsequent active-controlled trial in adults, increased mortality was not observed.

Evaluate pregnancy status prior to treatment of multidrug-resistant tuberculosis in females of reproductive potential. Females of reproductive potential should use effective contraception during treatment for multidrug-resistant tuberculosis (Esmail 2018).
Information related to bedaquiline use during pregnancy is limited. An increased risk of low birth weight infants was found following in utero bedaquiline exposure; however, this was found not to be clinically significant over time (Jaspard 2017; Loveday 2020; WHO 2020).
Tuberculosis (TB) disease (active TB) is associated with adverse fetal outcomes, including intrauterine growth restriction, low birth weight, preterm birth, and perinatal death (Esmail 2018; Miele 2020), as well as adverse maternal outcomes, including increased risks for anemia and cesarean delivery. Placental transmission may rarely occur with active maternal disease (Miele 2020).
Data are limited for use of second-line drugs during pregnancy (ie, bedaquiline). The treatment of multidrug-resistant tuberculosis in pregnant patients should be individualized; evidence to support a specific regimen is not available (ATS/CDC/ERS/IDSA [Nahid 2019]; WHO 2020). Bedaquiline should be reserved for use during pregnancy when an effective treatment regimen cannot otherwise be provided (CDC 2013).
Bedaquiline is present in breast milk.
Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended by the manufacturer during treatment and for 27.5 months after the last bedaquiline dose, unless infant formula is not available. Infants exposed to bedaquiline via breast milk should be monitored for adverse events, such as hepatotoxicity.
Susceptibility information for the background regimen against M. tuberculosis isolate should be obtained if possible. ECG should be obtained at baseline, after the initial 2 weeks, and monthly thereafter during therapy (ATS/CDC/ERS/IDSA [Nahid 2019]). Monitor ECG weekly with concurrent administration of other medications known to prolong the QTc interval (including fluoroquinolones, macrolide antibiotics, or clofazimine) or if the patient has ongoing or a history of conditions predisposing them to QTc prolongation (torsade de pointes, congenital long QT syndrome, hypothyroidism, uncompensated heart failure, bradyarrhythmias) (CDC 2013). If QTc prolongation is detected during therapy, monitor ECG frequently to confirm QTc return to baseline. Baseline potassium, calcium, and magnesium should be obtained and corrected, if abnormal, and monitored during therapy (ATS/CDC/ERS/IDSA [Nahid 2019]). Discontinue therapy (and all other QT prolonging drugs) if patient develops confirmed QTcF interval of >500 ms (confirmed by repeat ECG) or ventricular arrhythmia.
Monitor AST, ALT, alkaline phosphatase, and bilirubin, and symptoms of liver dysfunction (eg, fatigue, nausea, anorexia, jaundice, dark urine, liver tenderness, hepatomegaly) at baseline, monthly during treatment, and as needed. Monitor more frequently if patient has underlying hepatic disease or is receiving concomitant hepatotoxic drugs (CDC 2013). Further evaluate patients with evidence of liver dysfunction (AST/ALT and/or bilirubin elevations, and/or symptoms [eg fatigue, nausea, anorexia, hepatomegaly]). Discontinue if AST or ALT elevations are >5 times ULN and persist >2 weeks, are >8 times ULN, or if elevations also include total bilirubin >2 times ULN.
Monitor weekly for arthralgias, chest pain, headache, hemoptysis, nausea, and rash. Monitoring serum bedaquiline levels may be considered in patients with renal impairment. Sputum specimens should be evaluated monthly throughout treatment and at the end of treatment, even if cultures become negative. Specimens positive for M. tuberculosis (including pretreatment specimen) should be evaluated further by a laboratory (in conjunction with a state public health laboratory) that performs bedaquiline resistance testing (CDC 2013).
As a diarylquinoline antimycobacterial, inhibits the proton transfer chain of mycobacterial ATP synthase required for energy generation in M. tuberculosis. It is not active against human ATP synthase.
