Please suggest why so high fever?
Hi thereof long ago has your son started the TB medication? Was the fever there before starting medication? TB itself does cause fever whicChatDoctormonly occurs every 12 hours or so. If he has just started the medication I would give it some time (4 weeks) before the fever will settle down. In the meantime the use of antipyretic such as Paracetamol 500 mg DID will help. The fever may also be due to the response generated by the Anti-TB treatment from killing the TB organism. However, we should also take into consideration the effect of TB Chat Doctor.  There are many side effects from TB medication. One of the most common side effects is the effect on liver enzymes. Look out for Jaundice. He should have a liver function test done(LFT) and follow up from there.
