Thanks for using Healthcaremagic,
I have gone through available details, if insulin
is given to non diabetic then effects depend on how much (dose) is given.
Symptoms she had were due to low blood sugar(Hypoglycemia
) it can be easily corrected by giving Glucose
and something to eat to the patient.
There are no long term effects of this small amount of insulin as insulin is present in our body so do not worry at all.
If it was an error it is always preventable and hospital should take care in future.
Hope it helps.
