| Further clinical studies are needed to determine whether the moxifloxacin adds to the bactericidal activity of isoniazid or rifampin. |
| Occasionally, multidrug-resistant enterococci may be bacteriostatically susceptible to tetracycline, chloramphenicol, fluoroquinolones, novobiocin, and rifampin. |
| The patient was treated with isoniazid, rifampin, ethambutol, and streptomycin. |
| In vitro drug susceptibility indicated resistance to at least isoniazid and rifampin. |
| The organisms are treatable with tetracycline, erythromycin, rifampin, and by the sulfonamides. |
| When rifampin is given concomitantly with either halothane or isoniazid the potential for hepatotoxicity is increased. |
