Yes—Motrin (ibuprofen) can cause allergic reactions
Motrin contains ibuprofen, a type of NSAID (nonsteroidal anti-inflammatory drug). People can develop an allergy or hypersensitivity to ibuprofen, which can cause symptoms similar to other drug allergies.
What allergic reactions to Motrin can look like
Symptoms can range from mild to severe and may include hives, itching, swelling (often of the face, lips, or tongue), wheezing, or trouble breathing. Some people also react with a widespread rash or worsening asthma symptoms after taking an NSAID.
What if it’s not “true allergy”?
Some NSAID reactions are not classic antibody-driven allergy, but they still act like an allergy in the body. For example, ibuprofen can trigger NSAID-exacerbated respiratory disease, where nasal symptoms, wheezing, or asthma flare up after NSAIDs.
How soon would symptoms start?
Reactions can occur soon after taking the dose (sometimes within minutes to hours), but delayed rashes can also happen. If symptoms start after you take Motrin, treat it as a possible drug reaction.
What to do if you think you’re allergic to Motrin
Stop taking Motrin and seek medical advice. If you have trouble breathing, facial/tongue swelling, or widespread hives, get emergency care immediately.
Can you take other pain relievers instead?
This depends on your reaction and medical history. Many clinicians recommend avoiding the specific NSAID that caused the reaction. Ask a clinician whether acetaminophen (Tylenol) is safe for you, since it can be tolerated by some people who react to ibuprofen, but it still should be confirmed with your provider—especially if your reaction involved breathing problems.
If you’ve reacted before, why it matters
Repeated NSAID reactions can be more serious over time. Also, if you’ve had hives or breathing symptoms with Motrin, it’s especially important to document it for future medication safety.
When to seek urgent help
Call emergency services or go to the ER for symptoms like:
- trouble breathing or wheezing
- swelling of the face, lips, tongue, or throat
- fainting, severe dizziness
- rapidly spreading hives or a severe rash
