  • Isoniazid was widely used in the treatment of Mycobacterium avium complex as part of a regimen including rifampicin and ethambutol. (wikipedia.org)
  • Ethambutol (or streptomycin in children too young to be monitored for visual acuity) should also be included until the results of drug susceptibility studies are available, unless there is little possibility of drug resistance (see Section 1 above). (cdc.gov)
  • Therapy was prescribed for the first 2 months of isoniazid, rifampicin, ethambutol and piazoline. (who.int)

Rifapentine2
  • Three randomized controlled trials have shown that a new combination regimen of isoniazid (INH) and rifapentine (RPT) administered weekly for 12 weeks as directly observed therapy (DOT) is as effective for preventing TB as other regimens and is more likely to be completed than the U.S. standard regimen of 9 months of INH daily without DOT ( 2 5 ). (cdc.gov)
  • Other drugs that may cause flu-like symptoms include the tuberculosis medications rifapentine and isoniazid. (medicalnewstoday.com)
Regimen13
  • Recommendations against the use of INH-RPT (without a reference to quality of evidence) were made for patient categories in which 1) previous experience with treatment of TB or LTBI with any regimen has revealed an increased risk for adverse effects, drug interactions, or low efficacy or 2) studies have not provided adequate evidence of safety or efficacy. (cdc.gov)
  • The drug regimen typically requires daily or weekly oral administration for a period of three to nine months, often under Directly Observed Therapy (DOT) supervision. (wikipedia.org)

  • This interim guidance updates 2016 guidelines by recommending and providing implementation considerations for a novel 4-month daily treatment regimen, based on high-dose daily RPT with MOX, INH, and PZA ( 1 ) as a treatment option for U.S. patients aged ≥12 years with drug-susceptible pulmonary TB. (cdc.gov)
  • The regimen is intended for administration in settings where mycobacterial cultures, molecular and phenotypic drug susceptibility testing (DST), radiographic studies and other diagnostic tools, infrastructure for adverse event monitoring, patient-centered clinical care, and coordination with public health for case management are available.

(who.int)
  • While country-level data collection and reporting need further improvements, several countries have reported increasing levels of anti-tuberculosis drug resistance. (who.int)
  • Conversely, multidrug-resistant tuberculosis emerges as a result of underinvestment in the Stop TB strategy.2 The emphasis for action therefore needs to be both on strengthening basic control to prevent the emergence of drug resistance and on diagnosing and treating the cases of multidrug- and extensively drug-resistant tuberculosis effectively in order to prevent transmission.
