What are the side effects of insulin therapy for diabetes?

Donna Hill Howes, RN
Family Practitioner

Low blood sugar is the most common side effect of insulin. It is more common in people who have irregular eating patterns, those who exercise without adjusting their food intake or insulin dosage, and people being treated with intensive insulin therapy.

Insulin injections can cause an allergic reaction, such as itching, swelling, redness, stinging, or warmth at the site of the injection. These reactions usually occur in the first three weeks after beginning injections and disappear within a few days or weeks.

The most common side effects of inhaled insulin are headache, cough, and throat pain or irritation. Inhaled insulin may also cause bronchospasm (narrowing of air passages in the lungs), low potassium levels in the blood, and allergic reactions, which can be severe.
