I want to make you cautious. Do not play with TB. It can become drug resistant and can be very dangerous.
Akurit-4 contains 4 medicines: Isoniazide (H), Rifampicin
(E) and Pyrazinamide
(Z). H, R and Z can cause liver toxicity in 7-8% of cases. In such a case, there are standard guidelines to be followed. They are as follows: Do not stop Treatment as it can induce drug resistance
!! Shift to Syreptomycin (S), Ethambutol (E) and Levofloxacin
(L), all 3 being non toxic to liver. Let the jaundice clear and then gradually reintroduce H and R, in desensitizing dose if required. Later add Z and ultimately you will be on HREZ again. H (Isokin in your case) is the most liver toxic drug and has to be stopped. The jaundice may not settle till then.
