Thanks for your question on Healthcare Magic.
I can understand your concern.
Anti tubercular drugs are having many side effects.
Common side effects are gastritis, vomiting, nausea, abdominal fullness, heaviness etc.
Specific side effects with each drug are as follows.
1.
Levofloxacin can cause tendinitis, tendon rupture, QTc prolongation (arrhythmia),
hypoglycemia etc.
2. Rifampicin and isoniazid cause
drug induced hepatitis, neuropathy (due to folate and
pyridoxine deficiency).
3. Ethambutol can cause
optic neuritis, kidney damage etc.
So better to get done ecg, liver function test and Renal function test once every two monthly.
Avoid oily and spicy food. Drink plenty of fluids orally and keep your self hydrated. Avoid junk food.
Take high protein diet like pulses, protein powder etc.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
