Some providers may prefer to use AP in first trimester because of lack of systemic absorption and fetal exposure, secondary to theoretical concerns about possible teratogenicity with systemic medications. Criteria for stopping primary prophylaxis: CD4 > 200/mm3 for ![]() |
Mycobacterium tuberculosis INH-sensitive INH-resistant multidrug (INH and rifampin) resistant |
TST reaction ![]() Same; high probability of exposure to INH-resistant M. tuberculosis Same; high probability of exposure to multidrug M. tuberculosis |
INH 300 mg po qd plus pyridoxine 50 mg po qd x 9 mo INH 900 mg po biw plus pyridoxine 100 mg po biw x 9 mo Rifampin 600mg po qd x 4 mo. |
Rifampin 600 mg po qd x 4 mo | Some providers may choose to initiate phrophylaxis after the first trimester, because of concerns about possible teratogenicity. Anecdotal experience with rifampin has not been associated with adverse pregnancy outcomes. Pyrazinamide should generally be avoided, particularly in the first trimester, because of lack of information concerning fetal effects. INH use during pregnancy has been associated with elevated risk for hepatotoxicity and LFTs should be monitored. Choice of drugs requires consultation with obstetric experts and public health authorities. Consult with obstetric experts and public health authorities if alternative regimen required |

TMP-SMZ DS 1 po qd |
TMP-SMZ SS 1 po qd | If patient cannot tolerate TMP-SMZ, the recommended alternative is dapsone-pyrimethamine-leucovorin; however, because of the low incidence of TE during pregnancy and possible fetal risk with pyrimethamine, chemoprophylaxis may reasonably be deferred until after pregnancy Criteria for stopping primary prophylaxis: CD4 > 200/mm3 for ![]() |
Mycobacterium avium complex | CD4 <50 mm3 | Azithromycin 1200 mg po qw | Rifabutin 300 mg po qd | Some providers may prefer to defer prophylaxis until after the first trimester, because of general concerns about administering drugs in early pregnancy.
