If the person is conscious, give refined sugars or liquid carbohydrates. This should be followed by a meal of complex carbohydrates.

If the person is unconscious and cannot take anything orally, inject 100 c.c. of 25 % glucose intravenous.

If intravenous infusion not feasible, 0.5 to 1 mg of glucagon, intramuscular / subcutaneous injection can be given. Once consciousness is regained, treat as above.

Patients on long acting insulins and certain oral hypoglycemics (glibenclamide, chlorpropamide) may show recurrent and prolonged hypoglycemic reactions. They may require glucose infusions for several days, in many instances; thus better to hospitalize such patients.

After recovery, always look for, and correct, any precipitating cause.
