Hello The diagnosis is established , so please take care that in any condition don t stop the anti tubercular treatment till your doctor advise .When a patient visit my clinic I advise them to take these drugs ( 50 kg weight ) . Forecox ( rifampicin 225 mg + isoniazide 150 mg + ethambutol 400 mg + pyrazinamide 750 mg in one tablet ) take 2 tablet on empty stomach but if patient feel nausea and vomiting then take these tablets 3 hours after meal and also take some antacid . In the evening I prescribe levofloxacin 750 mg + pantaloc-D , these two after dinner . I usually advise this treatment for 3 months . After this I advise my patient to take Rifampicin 450 mg + isoniazide 300 mg in the morning . Levofloxacin 750 with pantaloc-D in the night after dinner . till another 3 months . After this rifampicin 450 + isoniazide 300 mg for another 6 month . One tear treatment completed in this way . Observe any symptoms like cough , hemoptysis , fever , weakness , if any , report at once to treating doctor . Regular x RAY after every 3 months with sputum for A F B if present . Blood after every 3 months for c b c & e s r . Since you are not producing sputum so it is presumed that no sputum or sputum for A F B negative patient can t spread tuberculosis because droplet ( sneezing , coughing spitting spreads tuberculosis ) from mouth or nose is the way with which PTB spread. So deal as mentioned above. Hope this will help you.
