What should I do if my 8-month-old baby has a fever and red bumps on their body?

Patient's question:

Baby is 8 months old, weighing 19 pounds. She had a fever at 3 PM on Friday. After taking cold medicine and fever-reducing medicine, she rested. By 9 PM that evening, red bumps had started to appear on her face. In the middle of the night, she was taken to the hospital, where she received more cold medicine and fever-reducing medicine. By 5 AM the next morning, large patches of red bumps had appeared on her entire face and neck. Her highest temperature reached 39.5°C, with frequent readings of 38.7°C. About ten days ago, I had a cold, and the baby might have been infected, developing clear nasal discharge. After I recovered from my cold, the baby suddenly developed a fever and red bumps. Now it's Sunday, and she has spots all over her body. The doctor suspects it might be an allergy. For the past two days (48 hours), taking fever-reducing medicine only lowers her temperature for four hours before it spikes again. The cause remains unknown. Blood tests show normal white blood cell counts. Possible conditions include viral cold, inflammation, childhood rubella, acute urticaria, etc. She has seen five or six doctors, each with their own opinions, but the consensus is that it's an allergy. She is breastfed. On the day she had a fever, her mother ate a few slices of dried pork jerky in the morning, but it seems unlikely to be related. She was also given roxithromycin and cold on the day she had a fever, but it's unclear if it could be a drug allergy. Searching online, conditions like Kawasaki disease seem unlikely, but it resembles childhood rubella. However, the fever keeps recurring. She is seeking medical advice.

Doctor's answer:

I'm glad to help you clarify this. According to your description, the child likely had an allergic reaction to the medication after taking it. You should stop taking the previously consumed cold medicine, roxithromycin, and fever-reducing medication, and do not take them anymore. Take oral vitamin C glucose, calcium gluconate, and diphenhydramine. If the child has yellow nasal discharge, yellow tongue coating, and a red throat, it is recommended to take Yinqiao Jiedu pills. If the child has clear nasal discharge, a white tongue coating, and a non-red throat, it is recommended to take cold soft capsules.
