Yes. Some children can have an allergic reaction to a fever reducer, including acetaminophen or ibuprofen. Reactions may range from mild skin symptoms, such as a rash or hives, to more serious symptoms like swelling, trouble breathing, vomiting, or unusual sleepiness. Because fever and viral illnesses can also cause rashes, it can be hard for parents to tell whether the medicine, the illness, or something else is responsible.
A fever medicine allergy rash in a child may appear as red patches, raised welts, or itchy hives shortly after a dose.
Lip swelling, facial swelling, wheezing, coughing, or trouble breathing can signal a more serious allergic reaction and need urgent attention.
Vomiting, sudden fussiness, dizziness, or a child seeming weak or unusually sleepy after medicine may need prompt medical review.
Although uncommon, acetaminophen can cause allergic reactions in some children, including rash, hives, swelling, or breathing symptoms.
Ibuprofen may trigger hives, swelling, wheezing, or worsening breathing symptoms in children who are sensitive to it or similar medicines.
Some reactions are side effects or illness-related symptoms rather than a true allergy. Timing, symptom pattern, and the specific medicine all matter.
Stop giving the suspected medicine unless a clinician has told you otherwise. If your child has trouble breathing, swelling of the face or mouth, fainting, or severe lethargy, seek emergency care right away. For milder symptoms like a rash or hives, contact your pediatrician promptly for guidance on next steps, safe alternatives, and whether the reaction should be documented as a medication allergy.
