HI Thanks for the question. Piriton
contains chlorophrniramine, an antihistaminic, h1 antagonist
, which itself directly donot have any side effects on blood counts. But, your doctor might have suggested this for the reason that if you are suffering from any allergic conditions where blood counts are abnormal (e.g high eosinophil count
where piriton is prescribed). In such cases you may need to do periodic blood tests to assess the improvement of the disease process. Hope I could answer your question. Wish you a speedy recovery.
