I Am Mrs. Leela Shankarnarayan From India. I Am 78

I am Mrs. Leela Shankarnarayan from India. I am 78 years old and weigh 53 kilos now after having lost after having lost 4 kilos during the year on account of continuous coughing with expectoration. The Sputem test conducted shows no infection and AFB seen. I have been prescribed with MontekLC as my Doctors think that it is an allergic condition. I am also advised to take Bcomplex tablets along with Montek LC. Am I on the right track?
