Common side effects
Heparinoid does not usually cause any side effects.
Some people can get a rash but this is rare. Some ingredients in heparinoid cream or gel can also cause skin reactions, such as contact dermatitis or other allergic reactions.
If this happens to you, stop using heparinoid and tell your doctor or pharmacist.
Serious allergic reaction
In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to heparinoid cream or gel.
Immediate action required: Call 999 now if:
- your lips, mouth, throat or tongue suddenly become swollen
- you're breathing very fast or struggling to breathe (you may become very wheezy or feel like you're choking or gasping for air)
- your throat feels tight or you're struggling to swallow
- your skin, tongue or lips turn blue, grey or pale (if you have black or brown skin, this may be easier to see on the palms of your hands or soles of your feet)
- you suddenly become very confused, drowsy or dizzy
- someone faints and cannot be woken up
- a child is limp, floppy or not responding like they normally do (their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head or focus on your face)
You or the person who's unwell may also have a rash that's swollen, raised, itchy, blistered or peeling.
These can be signs of a serious allergic reaction and may need immediate treatment in hospital.
Do not drive yourself to A&E.
The person you speak to at 999 will give you advice about what to do.
