as per your query ur son is suffering from fever
since ten days ..and u even said he has been kept on typhoid
treatment.. and today he has been given Rapither inj ..this inj is given for treatment of malaria
.. and fever is more in the evening..
but im sorry to say that u didnt provide us with blood test
reports whether it says malaria typhoid or both or if ur son is also having cough..
depending upon the report u can go for the right treatment to reduce the fever..
if ur son is also having cough u need also to get one x-ray to rule out TB as it also gives evening rise of temp..
and so all these have to be diagnosed and then treated,, you better ask ur doc and clarify these problems..
and tab paracetamol
should be given every 6th hourly to keep the temp normal..
so continue the treatment but clarify with your doc regarding the diagnosis..
thank u ..
