Clinical trials are conducted under widely varying designs, therefore, the adverse reaction rates reported in one clinical trial may not be easily compared to those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice. The data in Table 1 reflect the exposure of 55 patients with type 1 diabetes to NOVOLOG MIX 70/30 with a mean exposure duration of three months. The mean age was 43.2 years. Sixty-four percent were male and 100% were Caucasian. The mean body mass index (BMI) was 26.1 kg/m2. The mean duration of diabetes was 14.9 years.
The data in Table 2 reflect the exposure of 85 patients with type 2 diabetes to NOVOLOG MIX 70/30 with a mean exposure duration of three months. The mean age was 62.7 years. Fifty-four percent were male and 100% were Caucasian. The mean body mass index (BMI) was 28.1 kg/m2 . The mean duration of diabetes was 15.0 years.
Common adverse reactions were defined as events occurring in ≥5%, excluding hypoglycemia, of the population studied. Common adverse events occurring at the same rate or greater for NOVOLOG MIX 70/30-treated subjects than on comparator-treated subjects during clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus (other than hypoglycemia) are listed in Table 1 and Table 2, respectively. The trial was a three-month, open-label trial in patients with type 1 or type 2 diabetes who were treated twice daily (before breakfast and before supper) with NOVOLOG MIX 70/30.

Severe Hypoglycemia
Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including NOVOLOG MIX 70/30 [see Warnings and Precautions (5.3)]. The rates of reported hypoglycemia depend on the definition of hypoglycemia used, diabetes type, insulin dose, intensity of glucose control, background therapies, and other intrinsic and extrinsic patient factors. For these reasons, comparing rates of hypoglycemia in clinical trials for NOVOLOG MIX 70/30 with the incidence of hypoglycemia for other products may be misleading and also, may not be representative of hypoglycemia rates that will occur in clinical practice.
Severe hypoglycemia requiring the assistance of another person and/or parenteral glucose infusion or glucagon administration has been observed in clinical trials with insulin, including trials with NOVOLOG MIX 70/30.
The incidence of severe hypoglycemia in adult patients receiving subcutaneous NOVOLOG MIX 70/30 was 16% and 4 % for type 1 and type 2 diabetes patients respectively at 12 weeks [see Clinical Studies (14)].
Allergic Reactions
Patients have experienced reactions such as erythema, edema or pruritus at the site of NOVOLOG MIX 70/30 injection. These reactions usually resolve in a few days to a few weeks, but in some occasions, have required discontinuation of NOVOLOG MIX 70/30. Severe cases of generalized allergy (anaphylaxis) have been reported [see Warnings and Precautions (5.5)].
Insulin initiation and glucose control intensification
Intensification or rapid improvement in glucose control has been associated with 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.
Lipodystrophy
Long-term use of insulin, including NOVOLOG MIX 70/30, can cause lipodystrophy at the site of repeated insulin injections. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue), and may affect insulin absorption [see Dosage and Administration (2.1)].
Weight gain
Weight gain can occur with some insulin therapies, including NOVOLOG MIX 70/30, and has been attributed to the anabolic effects of insulin and the decrease in glycosuria.
Peripheral Edema
Insulin products, including NOVOLOG MIX 70/30, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
