Hi, TB infection latent or in early active stages in the lungs usually is only one lung and looks like a speckles of little densities. Treatment for latent TB the standard treatment is six to nine months of isoniazid(H) alone. 6-9H
http://en.wikipedia.org/wiki/Isoniazid
The standard "short" course treatment for active TB is isoniazid, rifampicin, pyrazinamide, and ethambutol for two months, then isoniazid and rifampicin alone for a further four months. The patient is considered cured at six months (although there is still a relapse rate of 2 to 3%).
2HREZ/4HR3
means isoniazid(H), rifampicin(R), ethambutol(E), pyrazinamide(Z) daily for two months, followed by four months of isoniazid and rifampicin given three times a week.

Take extra care to follow your doctors instructions carefully and don't miss doses of medications or you could end up with MDR-TB which is hard to treat, and most people can't afford the more expensive medications to treat it, even if you have red tears and are nauseous, or "feel good" on first line treatment don't stop meds because the consequences will be far worse:
