Tuberculosis-TB

What Are Tuberculosis-TB?

Tuberculosis (TB) caused by Mycobacterium tuberculosis remains one of the world’s deadliest infectious diseases, with 10.6 million new cases and 1.3 million deaths annually. Effective treatment requires a minimum of 6 months of combination antibiotic therapy — short courses or monotherapy inevitably lead to resistance. AmozonPill stocks 32 generic TB medications including all four WHO first-line agents and fixed-dose combination tablets — sourced from WHO-prequalified, FDA-inspected manufacturers at up to 95% below brand-name prices. 

 Drug Classes Available

• WHO First-Line TB Agents — Individual: Rifampicin (R), Isoniazid (H), Pyrazinamide (Z), Ethambutol (E) — the four components of the standard WHO TB regimen. Used together for the 2-month intensive phase; Rifampicin + Isoniazid for the 4-month continuation phase. 
• Fixed-Dose Combination (FDC) Tablets: 2HRZE/4HR — Rifampicin + Isoniazid + Pyrazinamide + Ethambutol (intensive phase), and Rifampicin + Isoniazid (continuation phase) in single-tablet combinations. WHO and global TB programmes prefer FDCs to improve adherence and prevent accidental monotherapy. 
• Adjunct & Supplementation: Pyridoxine (Vitamin B6) — mandatory with Isoniazid in malnourished patients, pregnant women, HIV-positive individuals, and those with peripheral neuropathy risk, as Isoniazid depletes B6. 
• Second-Line TB Agents: Levofloxacin, Moxifloxacin, Amikacin — used in drug-resistant TB (MDR-TB, XDR-TB) under specialist supervision as part of WHO-recommended MDR-TB regimens.

 How to Choose the Right Product

TB treatment must be prescribed and supervised by a physician or TB specialist following bacteriological confirmation and susceptibility testing. The standard WHO regimen for drug-sensitive TB is: 2 months of Rifampicin + Isoniazid + Pyrazinamide + Ethambutol daily (intensive phase), followed by 4 months of Rifampicin + Isoniazid daily (continuation phase) — total 6 months. Fixed-dose combination tablets are strongly preferred to simplify dosing and prevent resistance. Always add Pyridoxine 25–50 mg daily with Isoniazid. Directly Observed Therapy (DOT) is the gold standard for adherence support. 

Frequently Asked Questions

Why does TB treatment require at least 6 months? 

Mycobacterium tuberculosis has a unique ability to enter a semi-dormant state within host cells — dormant bacilli are not killed by most antibiotics and can reactivate months or years later. The 6-month regimen is specifically designed to eliminate both actively dividing and dormant populations. Shorter courses leave dormant bacilli viable, leading to TB relapse. 

What happens if I miss doses during TB treatment? 

Missing doses allows the bacterial population to continue growing, increasing the risk of treatment failure and — most critically — the development of drug-resistant TB (MDR-TB). MDR-TB requires 18–20 months of second-line treatment, is significantly more toxic, and has much lower cure rates. Never stop or interrupt TB treatment without specialist guidance. 

Why does Rifampicin turn urine and body fluids orange? 

Rifampicin is excreted in urine, sweat, tears, and saliva, turning them orange-red. This is harmless and expected. Warn contact lens wearers — Rifampicin permanently stains soft contact lenses orange. Switch to glasses during the Rifampicin treatment course

What is the difference between TB infection and TB disease? 

Latent TB infection (LTBI) is when M. tuberculosis is present in the body but contained by the immune system — no symptoms, not infectious. Active TB disease is when the bacillus breaks out and multiplies — causing symptoms and being infectious. LTBI can be treated with 3–6 months of Isoniazid preventive therapy (IPT) to prevent progression to active disease. 

Can TB be transmitted in the household? 

Yes. Pulmonary TB is transmitted by airborne droplets from coughs, sneezes, or speech. Close household contacts of a TB patient require TB screening (TST or IGRA test, and chest X-ray). Contacts who are TST/IGRA positive should receive Isoniazid Preventive Therapy to prevent developing active TB. 

Is drug-resistant TB (MDR-TB) treatable? 

MDR-TB (resistant to Rifampicin and Isoniazid) is treatable but challenging — requiring 18–24 month regimens with second-line drugs (fluoroquinolones, injectable agents). WHO newer regimens including Bedaquiline, Delamanid, and the BPaL regimen (Bedaquiline + Pretomanid + Linezolid) have significantly improved MDR-TB outcomes. Treatment must be managed at specialist MDR-TB centres.
