My 1 years 7-months old son has been recently diagnosed with 'papular rash' by our pediatric doctor. He has been on daily dosage of - 1) Montair granules for 4-weeks. 2) Xyzal syrup 2 ml for 10-days. Our doctor had mentioned that if things settle down within 1-2 weeks, dosages could be reduced, however, he is currently out of town for 3-months. My son already took these medicines for 2-weeks & 2-3 new rashes have come up since past 2-3 days. Also, the existing ones seem to get cured. Should we continue the same medicines for the entire duration of 4-weeks or, is there any dosage reduction required?
