Thanks for your query.
Firstly, none of the drugs for TB cause burning sensation in penis.
Since your husband is a diabetic, chances of urinary infection of bladder and urine passage (urethra
) are very high.
Loose stools are more likely due to acute infection of the intestines, than other medicines.
Therefore, I suggest that
* you get his urine examination (routine, microscopic and culture/sensitivity test) done at the earliest, before the infection spreads into the entire body. Consult his treating doctor who will prescribe empirical antibiotics, till such time the culture/sensitivity report is available.
* A 5-days' course of metronidazole
will cure his loose stools. Your doctor will prescribe it in appropriate doses.
* Please ensure that his diabetes
is brought under ideal control at the earliest.
