General

The most common adverse reactions observed with insulin therapy include hypoglycemia, allergic reactions, local injection site reactions, lipodystrophy, rash, and pruritus.[Ref]

Metabolic

Very common (10% or more): Hypoglycemia[Ref]

Hypersensitivity

Uncommon (0.1% to 1%): Local reactions such as redness, swelling, or itching at the injection site
Very rare (less than 0.01%): Systemic reactions[Ref]

Hypersensitivity side effects have included both local and systemic reactions. These reactions are becoming rare (less than 1% of patients) due to the use of biosynthetic human insulin. Local reactions have presented as erythema, swelling, heat, or subcutaneous nodules. They usually occurred within the first two weeks of therapy and then disappear. Systemic allergy is a generalized allergy to insulin which may present as a rash over the whole body, shortness of breath, wheezing, drop in blood pressure, fast pulse, or sweating. Severe cases may be life-threatening.[Ref]

Cardiovascular

Frequency not reported: Peripheral edema[Ref]

Insulin may cause sodium retention and edema, especially if previously poor metabolic control is improved by intensified insulin therapy.[Ref]

Dermatologic

Uncommon (0.1% to 1%): Lipodystrophy
Frequency not reported: Rash, pruritus[Ref]

Immunologic

Frequency not reported: Anti-insulin antibodies[Ref]

Other

Frequency not reported: Weight gain[Ref]

Weight gain has been attributed to the anabolic effects of insulin and the decrease in glycosuria.[Ref]

Local

Frequency not reported: Injection site reactions[Ref]

Injection site reactions including pain, redness, hives, inflammation, bruising, swelling, and itching, may occur. These reactions are usually transitory and may be related to factors other than insulin, such as irritants in the skin cleansing agent or poor injection technique.[Ref]
