Drugs for TB

we give the 4 drugs for 2 months and after that we give the first 2 drugs for 4 months. that means 6 months in total.

we extend the treatment for 12 months in TB meningitis and for 9 months in pregnancy and osteomyelitis.

we add steroids for patients with TB meningitis and TB pericarditis.

we don't give PZA for pregnant patients.

all these drugs can cause liver toxicity.

INH can cause peripheral neuropathy.

RIF changes the color of the secreted fluids to red.

PZA can cause benign hyperuricemia.

ETB affects the eye and cause optic neuritis.

because of B6 Deficiency, so patients on PZN should take vit B6

sorry, INH not PZA
