my 11 year old son had an insect bite with a palm sized rash with no blister or pus or any other indications. He was administered antibiotic and brifen as well as citrizine twice a day as per his weight. After 5 days the rashes suddenly appeared over the torso with inflamation of site of bite but still looked healthy. Local application of Thrombophob (heparin) was advised for reducing swelling and blood clot which was effective on site of wound but flared up the rest of the places. On sixth day the rashes appeared on hands as well. All drugs were withdrawn and he was administered wyslone 10 mg twice a day tapering to 5 mg twice a day and 5 mg once a day. after first dose of wyslone, there is remarkable reduction in rashes. When can the wyslone be withdrawn? and what dose? Today is first day.
