Can Amoxicillin cause rashes in babies?

Question

Hello doctor,

My 9-month-old daughter had a rash for three days. It started with small, discreet spots on the legs and lower back. The next day she had a rash on her face and body. These are red, flat spots and it itches. She has no fever and is in good general condition. We consulted a doctor who was thinking about the onset of chickenpox. However, the evolution of the rash does not seem to go in this direction. The doctor cannot give us any other diagnosis. We fear an Amoxicillin rash. The rashes first appeared as small spots, and our daughter finished an 8-day treatment for otitis.

Do you think that is possible?
What else could it be?

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I have gone through your case. In my opinion, there are two to three possibilities for the rash.

First yes, it could be drug eruption as the rash is itchy and appeared after she took treatment for otitis. Drug rash can either occur immediately or even after six weeks.
Second, it could be due to any viral or bacterial infection which first caused otitis and then the rash. But as she did not have a fever and there are no vesicles so in my opinion, it is not chickenpox.
The third possibility is an insect bite or papular urticaria.
The last possibility is Gianotti-Crosti syndrome. It is common in children of this age group and the rash in it is itchy.

Treatment: Please apply 1 percent Hydrocortisone cream on lesions two times a day for ten days. Rash will disappear in two to three weeks.

I hope I have answered your question.

Hi,

Welcome back to icliniq.com.

Yes, it means that she is allergic to Penicillin medicine and she should not use it in the future. On the clinical picture, (attachment removed to protect patient identity). I told you three different diagnoses. Confirmation can only be done by skin biopsy. However, clinically it is not chickenpox.
