Medicines That May Cause a Rash in Children

Children react to medicines in different ways. Some kids may get a rash. Here are some that can cause rashes in your child.

  • Alternative and herbal medicines, such as echinacea
  • Antibiotics, such as cephalosporins, penicillin, or sulfonamides
  • Anti-seizure medicine, such as amotrigine, carbamazepine, ethosuximide, phenytoin, and zonisamide
  • Barbiturates, such as mephobarbital, metharbital, and phenobarbital
  • Contrast dyes used in X-rays and MRIs
  • Pain medications that have codeine

If your child gets a rash after starting a new medicine, call the doctor right away. Your doctor will most likely tell you to stop giving the medication and prescribe a different one. Your doctor may also suggest giving your child an antihistamine such as diphenhydramine. If your child gets a rash from a non-prescription medicine, stop giving it immediately. Call your doctor if you need suggestions for a different drug.
