General

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

Metabolic

Hypoglycemia is the most frequently reported adverse reaction with insulin therapy. It occurs if the dose of the insulin is too high in relation to the insulin requirement. In clinical trials, the frequency of hypoglycemia varied with patient population, dose regimens, and level of glycemic control. Weight gain has been attributed to the anabolic effects of insulin and the decrease in glycosuria.[Ref]

Very common (10% or more): Hypoglycemia (69%)
Frequency not reported: Weight gain[Ref]

Hypersensitivity

Very rare (less than 0.01%): Anaphylactic reactions
Frequency not reported: Allergic reactions[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.[Ref]

Ocular

Frequency not reported: Transient, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy[Ref]

Rapid improvement or intensification of in glucose control has been associated with transitory, reversible ophthalmologic refraction disorder; however, long-term glycemic control decreases the risk of diabetic retinopathy.[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

Frequency not reported: Lipodystrophy, rash, pruritus[Ref]

Gastrointestinal

Common (1% to 10%): Dyspepsia, diarrhea, abdominal pain[Ref]

Immunologic

Common (1% to 10%): Influenza-like symptoms
Frequency not reported: Anti-insulin antibodies[Ref]

In a 3-month, open-label study, anti-insulin antibodies and cross-reacting anti-insulin antibodies were monitored in patients using this insulin compared with an insulin mix of 70% NPH (human insulin isophane suspension) and 30% regular (human insulin injection). Changes in cross-reactive antibodies were more common after this mix but these changes did not correlate with a change in HbA1c or increase in insulin dose. The clinical significance of these antibodies has not been established. Antibodies did not increase further after long-term exposure (greater than 6 months).[Ref]

Musculoskeletal

Common (1% to 10%): Back pain, skeletal pain[Ref]

Nervous system

Rapid improvement or intensification of in glucose control has been associated with acute and painful peripheral neuropathy; however, long-term glycemic control decreases the risk of neuropathy.[Ref]

Very common (10% or more): Headache (19%)
Common (1% to 10%): Neuropathy[Ref]

Other

Postmarketing reports: Medication errors in which other insulins have been accidentally substituted[Ref]

Respiratory

Common (1% to 10%): Pharyngitis, rhinitis , upper respiratory tract infection[Ref]
