Doctor insights on: What To Do If Your Child Gets An Allergic Reaction To An Antibiotic

History & exam fit: Allergic reaction to meds usually involves typical itchy rash (measles like or hives). From first exposure to onset of reaction usually 7-10 days and on second exposure within minutes to hours. Get baby to experienced allergist who can examine baby and get detailed history. Except for penicillin there is no reliable skin testing for meds so history, exam are key. Take clear close-up pics of rash. ...Read more

Label explains: I'd first advise calling your doctor who depending upon the SEVERITY of your reaction may prefer you be seen in the ER.

Take a break!: I would not advise it at this time as your body is in the midst of a battle against the antibiotic.

Criteria for MS: Hi JeriS,
Typically symptoms related to MS are on one side of the body but can be both sides as well occasionally. The symptoms typically go away followed by a period with no symptoms followed by returning of symptoms perhaps elsewhere in the body. If this is the scenario you are experiencing then you may need to consult with a Neurologist who can guide you in the right direction.
Best of luck ...Read more

Amoxicillin: Amoxicillin is very closely related to penicillin. People with a true penicillin allergy like you (causing hives) should not take amoxicillin. I would suggest stopping the medication and calling your doctor right away to find out what to do next. You may need medication to stop the allergic reaction and perhaps a different antibiotic, depending on the reason it was prescribed.

People have been known to show allergic symptoms after taking antibiotics for several days and even if they have taken the same antibiotic before and have not had problems.

I hope this answers your question. Thanks! ...Read more
