PRESCRIBED FOR: Insulin is prescribed for the treatment of type 1 and type 2 diabetes mellitus.

SIDE EFFECTS: Hypoglycemia is the most common side effect that may occur during insulin therapy. Symptoms of hypoglycemia include:

Patients may experience blurred vision if they have had elevated blood sugar levels for a prolonged period of time and then have the elevated levels rapidly brought to normal. This is due to a shift of fluid within the lens of the eye. Over time, vision returns to normal. Other side effects that may occur include headaches, skin reactions (redness, swelling, itching or rash at the site of injection), worsening of diabetic retinopathy, changes in the distribution of body fat (lipodystrophy), allergic reactions, sodium retention, and general body swelling. Insulin causes weight gain and may reduce potassium blood levels. In addition to these side effects, inhaled insulin (Afrezza) may cause throat pain or irritation and cough and patients should inform their healthcare professional of any unresolved symptoms affecting the lungs for follow up.
