NSAIDs can sometimes cause serious side effects, although most of them are rare.
Possible serious side effects of NSAIDs include:
- an allergic reaction (anaphylaxis) – causing symptoms such as a swollen throat or tongue, a raised, itchy rash or difficulty breathing

- kidney problems – causing symptoms such as shortness of breath, blood in your pee, or swelling in your ankles, feet or hands
Other side effects
These are not all the possible side effects of NSAIDs. Some side effects are rare but serious and you may need to contact 111 for advice.
Always check the information leaflet that comes with your medicine.
Reporting side effects
You can report any suspected side effect using the Yellow Card safety scheme.
Visit the Yellow Card website for more information about reporting side effects.
Who can take NSAIDs
Most adults can take non-steroidal anti-inflammatory drugs (NSAIDs). They're not usually recommended if you're pregnant or breastfeeding.
Talk to your doctor or a pharmacist if you're pregnant or breastfeeding so they can decide on the best treatment for you and your baby.
Children can take some NSAIDs, such as ibuprofen and naproxen, if prescribed, but do not give aspirin to children under 16.
Taking NSAIDs with alcohol, food or other medicines
Taking NSAIDs with some other medicines can cause side effects and is not recommended.
It can cause problems if you take NSAIDs with medicines such as:
- other NSAIDs
- anticoagulants (such as warfarin)
- steroids
- antidepressants
- medicines to lower blood pressure
You can eat and drink normally while taking NSAIDs, but drinking a lot of alcohol may increase the risk of side effects or irritate your stomach.
