Hello I am iftikhar memon from pakistan .my son 1 year old now was diagnosed having urticaria multiform when he developed rashes on body and swollen lips and runny nose .all of sudden .dr prescribed him syp zyrtec and ketotifen 5ml bd both for 4 weeks and gave him injection decaderon 4mg stat. From few days we have noticed that he is having excessive urination. .we are concerned that is it due to these anti allergigs that we gave or something else ??and now as his rashes are subsided we also apply hydrozol cream for local application. How long we continue medicines. Otherwise he is healthy eating sleeping well.
