Like all medicines, short-acting insulin can cause side effects, although not everyone gets them. If you do have side effects such as problems where you inject, they usually happen in the first few weeks of starting insulin.
There are things you can do to help cope with these common side effects of short-acting insulin:
Speak to your doctor or diabetes nurse if the advice on how to cope does not help and a side effect is still bothering you or does not go away.
You think someone's having a severe hypo and they're not responding normally or they're unconscious, and:
- a glucagon injection is not available or you do not know how to use it
- you've given a glucagon injection and they have not recovered within 10 minutes
- they've been drinking alcohol
In rare cases, it's possible to have a serious allergic reaction to short-acting insulin (anaphylaxis).
These are not all the side effects of short-acting insulin. For a full list, see the leaflet inside your medicine packet.
