Dear Doctor, My son is 4-1/2 years old. 2 months ago we have done mantox test and reading was 15 x 15 mm. (the lab technician wrote 10 x 10 mm, later doctor checked it and put 15 x 15 mm). The doctor advised to start Rifa i-6 kid forte tablet one daily for six months. One week before we consulted another pediatrician and taken x-rays, and mantox test again. The result was negative and the new doctor advised to stop Rifa i-6 kids forte tablet. My son was only on 1-1/2 on this medication. Do we actually stop this medication or we have to continue for at least 3 months or 6 months. We are in confusion currently. Kindly provide your valuable suggestion doctor. Thanking you, Dileep
