Hi and thanks for the query,
repeated episodes of sore throat
need to be evaluated carefully. A few reasons might explain this. the first is the drug used might not be appropriate, or is given in sub optimal doses or less than the normal prescribed duration of time. Secondly, the Bacterium causing the infection might developed resistance to this particular drug.
It might necessary to exclude other predisposing factors like excessively large tonsils that predispose to recurrent infections. This might require to be removed surgically depending on the frequency of recurrence and the appreciation of the ENT specialist
. Continues episodes of sore throat could lead to complications like joint and heart disease
I suggest you book an appointment with an ENt specialist for a proper evaluation and management.
Thanks and best regards,
