For Healthcare Professionals
Applies to insulin isophane / insulin regular: subcutaneous suspension.
General
Adverse reactions observed with insulin therapy include hypoglycemia, allergic reactions, local injection site reactions, lipodystrophy, rash, pruritus, weight gain, and edema.[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. 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.
There have been rare reports of patients with hypersensitivity reactions to human insulins who have tolerated insulins of animal origin.[Ref]
Cardiovascular
Insulin may cause sodium retention and edema, especially if previously poor metabolic control is improved by intensified insulin therapy.[Ref]
Frequency not reported: Peripheral edema[Ref]
Dermatologic
Uncommon (0.1% to 1%): Lipodystrophy
Frequency not reported: Rash, pruritus[Ref]
Metabolic
Very common (10% or more): Hypoglycemia[Ref]
Ocular
Refraction anomalies may occur upon initiation of insulin; symptoms are usually transient. Intensification of insulin therapy may be associated with temporary worsening of diabetic retinopathy.[Ref]
Frequency not reported: Refraction anomalies, temporary worsening of diabetic retinopathy[Ref]
Local
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]
Frequency not reported: Injection site reactions[Ref]
Other
Weight gain has been attributed to the anabolic effects of insulin and the decrease in glycosuria.[Ref]
Frequency not reported: Weight gain[Ref]
Immunologic
Frequency not reported: Anti-insulin antibodies[Ref]
Nervous system
Frequency not reported: Acute painful neuropathy[Ref]
Fast improvement in blood glucose has been associated with acute painful neuropathy, which is generally reversible.[Ref]
