Hypoglycemia Due to Medication Errors [see Warnings and Precautions ( 5.4 )]. Hypersensitivity Reactions [see Warnings and Precautions ( 5.5 )]. Hypokalemia [see Warnings and Precautions ( 5.6 )] . Adverse reactions associated with HUMALOG include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, pruritus, and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying designs, the adverse reaction rates reported in one clinical trial may not be easily compared with those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice. Common adverse reactions, excluding hypoglycemia, were defined as events that occurred in ≥5% of patients treated with insulin lispro or regular human insulin. The frequencies of adverse reactions during HUMALOG clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus are listed in the tables below. Table 1: Adverse Reactions That Occurred in ≥5% in Patients with Type 1 Diabetes Mellitus HUMALOG (%) (n=81) Regular human insulin (%) (n=86) Flu syndrome 34.6 32.6 Pharyngitis 33.3 33.7 Rhinitis 24.7 29.1 Headache 29.6 22.1 Pain 19.8 16.3 Cough increased 17.3 17.4 Infection 13.6 20.9 Nausea 6.2 15.1 Accidental injury 8.6 11.6 Surgical procedure 6.2 14.0 Fever 6.2 11.6 Abdominal pain 7.4 8.1 Asthenia 7.4 8.1 Bronchitis 7.4 7.0 Diarrhea 8.6 5.8 Dysmenorrhea 6.2 7.0 Myalgia 7.4 5.8 Urinary tract infection 6.2 4.7 Table 2: Adverse Reactions That Occurred in ≥5% in Patients with Type 2 Diabetes Mellitus HUMALOG (%) (n=714) Regular human insulin (%) (n=709) Headache 11.6 9.3 Pain 10.8 10.0 Infection 10.1 7.6 Pharyngitis 6.6 8.2 Rhinitis 8.1 6.6 Flu syndrome 6.2 8.2 Surgical procedure 7.4 6.8 Insulin initiation and intensification of glucose control Intensification or rapid improvement in glucose control has been associated with a transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy. However, long-term glycemic control decreases the risk of diabetic retinopathy and neuropathy. Hypoglycemia Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including HUMALOG. Lipodystrophy Long-term use of insulin, including HUMALOG, can cause lipodystrophy at the site of repeated insulin injections or infusion. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue), and may affect insulin absorption [see Dosage and Administration ( 2.2 )] . Weight gain Weight gain can occur with insulins, including HUMALOG, and has been attributed to the anabolic effects of insulin and the decrease in glucosuria. Peripheral Edema Insulins, including HUMALOG, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy. Adverse Reactions with Continuous Subcutaneous Insulin Infusion (CSII) — HUMALOG U-100 In a 12-week, randomized, crossover study in adult patients with type 1 diabetes (n=39), the rates of catheter occlusions and infusion site reactions were similar for HUMALOG U-100 and regular human insulin treated patients ( see Table 3 ). Table 3: Catheter Occlusions and Infusion Site Reactions HUMALOG U-100 (n=38) Regular human insulin (n=39) Catheter occlusions/month 0.09 0.10 Infusion site reactions 2.6% (1/38) 2.6% (1/39) In a randomized, 16-week, open-label, parallel design study of pediatric patients with type 1 diabetes, adverse reactions related to infusion-site reactions were similar for insulin lispro and insulin aspart (21% of 100 patients versus 17% of 198 patients, respectively). In both groups, the most frequently reported infusion site reactions were infusion site erythema and infusion site reaction. Allergic Reactions Local Allergy — As with any insulin, patients taking HUMALOG may experience redness, swelling, or itching at the site of the injection. These minor reactions usually resolve in a few days to a few weeks, but in some occasions, may require discontinuation of HUMALOG. Systemic Allergy — Severe, life-threatening, generalized allergy, including anaphylaxis, may occur with any insulin, including HUMALOG. Generalized allergy to insulin may cause whole body rash (including pruritus), dyspnea, wheezing, hypotension, tachycardia, or diaphoresis. In controlled clinical trials, pruritus (with or without rash) was seen in 17 patients receiving regular human insulin (n=2969) and 30 patients receiving HUMALOG (n=2944). Localized reactions and generalized myalgias have been reported with injected metacresol, which is an excipient in HUMALOG [see Contraindications ( 4 )] . Antibody Production In large clinical trials with patients with type 1 (n=509) and type 2 (n=262) diabetes mellitus, anti-insulin antibody (insulin lispro-specific antibodies, insulin-specific antibodies, cross-reactive antibodies) formation was evaluated in patients receiving both regular human insulin and HUMALOG (including patients previously treated with human insulin and naive patients). As expected, the largest increase in the antibody levels occurred in patients new to insulin therapy. The antibody levels peaked by 12 months and declined over the remaining years of the study. These antibodies do not appear to cause deterioration in glycemic control or necessitate an increase in insulin dose. There was no statistically significant relationship between the change in the total daily insulin dose and the change in percent antibody binding for any of the antibody types. 6.2 Postmarketing Experience The following additional adverse reactions have been identified during post-approval use of HUMALOG. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Medication errors in which other insulins have been accidentally substituted for HUMALOG have been identified during post-approval use. Localized cutaneous amyloidosis at the injection site has occurred. Hyperglycemia has been reported with repeated insulin injections into areas of localized cutaneous amyloidosis; hypoglycemia has been reported with a sudden change to an unaffected injection site.
