The short explanation
It may be. Some painkillers, particularly a group called NSAIDs, are a known trigger for hives in some people. Hives appear as itchy, raised red or pale welts that can come and go and move around the body. A reaction within an hour of taking a medicine suggests the medicine could be the trigger, though other causes such as infections, foods or stress can also coincide. Avoid taking that painkiller again until you have spoken to a doctor, and note the name of the medicine. A doctor can help confirm whether this was likely a drug reaction and suggest which painkillers are safer for you. If you ever develop swelling of the lips, tongue or throat, trouble breathing or feel faint after a medicine, that is an emergency.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- People who react to one NSAID may react to others in the same group. Your doctor can advise which alternatives may be suitable.
- Keep a record of the medicine name and tell every doctor and pharmacist you see.
- Hives from a medicine often settle within a day or so after stopping, but can last longer.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot confirm that your rash was caused by the painkiller. A doctor will review the timing and your history.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Was this likely a reaction to the painkiller?
- Which painkillers should I avoid in future?
- Which ones may be safer for me?
- Should I see an allergy specialist?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you develop swelling of the lips, tongue or throat, wheezing, trouble breathing or feel faint.
Get help the same day
