What medicines, herbal products and homeopathic medicine interfere with platelet function or clotting?
Some medicines, herbal products, homeopathic medicines and dietary supplements can interfere with platelet function or clotting and may delay healing.
If you have a bleeding disorder, talk to your haemophilia centre before taking:
- Medicines containing Aspirin
- Non-steroidal anti-inflammatory drugs (NSAIDs). Sometimes they are called ‘topical non-steroidal anti-inflammatory drugs’ or just ‘topical anti-inflammatories’. They contain an anti-inflammatory medicine such as ibuprofen, diclofenac, felbinac, ketoprofen, piroxicam or naproxen etc and come in various brand names.
- Pain relief gels containing NSAIDs e.g. voltarol, ibuprofen, ibuleve, nurofen, deep relief and deep heat
- Analgesic creams, rubs, and sprays containing NSAIDs.
- Blood thinners such as warfarin and heparin.
- Other medicines that claim to treat bleeding, bruising or improve clotting.

Medicine when you have a cold
Many medicines sold for colds have ibuprofen, aspirin and naproxen in them, which you should not take if you have a bleeding disorder. Paracetamol and codeine preparations do not interfere with blood clotting and are therefore suitable to use.
If you are uncertain about whether any medication may affect platelet function or clotting, check with your haemophilia centre before taking it. You can also ask your local pharmacist for advice if you are unsure about what medication contains NSAIDs.
