Multidrug resistance is defined as resistance to at least isoniazid and rifampin. Treatment requires at least three drugs to which the organism is sensitive and should continue for 12 to 24 months after sputum conversion. Initial therapy may consist of five, six, or even seven drugs.
Three to 6 months is too short a drug regimen.
Therapy is long but not indefinite
Treatment is required for 1 to 2 years, not several years.
