Hello Get in sputum for A F B is a confirmatory test for pulmonary tubecurculosis.
For confirmation also get in one more
X ray chest .
Get in anti tubercular treatment as soon as possible.
When such patient visit I advise my patient to take as :
FORECOX ( rfampicin225 mg+isoniazide 150mg+
pyrazinamide 750mg+ethmbutol400 mg in each tablet) take 2 tablets on empty stomach or 3 hours after meal . I also advise my patient to take Pantaloc-D with 2 forecox .
In the evening take
levofloxacin 750 mg +pantaloc-d .
This treatment is for 3 months .
After this take
rifampicin 450 mg on empty stomach .
In the night same levofloxacin+pantaloc-d .
This is for next 6 months .
Now get in X RAY chest to rule out any fresh lesion.
