Hi, I am Dr Mbong.
Allergies in some persons can be enough to cause swollen tonsils (tonsilitis
). If that is the cause then claritin
will be fine (sleepiness is one of its side effects).
However if she is developing a fever
again, then one has to rull out an infectious cause (bug) or some local complication of the swollen tonsils such as an ear or nose infection for a swollen tonsils can prevent normal aeration of these stuctures or draining (into the throat) of secretions they produce.
The fever may also be due to some concomittant infection which had gone un-noticed.
Please kindly see her physician for further investigation.
I wish her quick recovery,
