Humulin N (insulin human recombinant) [Human insulin (rDNA origin) isophane suspension] is a man-made insulin product indicated for glucose control in patients with diabetes. Hypoglycemia (low blood sugar) is a frequent side effect of Humulin N (insulin). Symptoms of low blood sugar may include headache, nausea, hunger, confusion, drowsiness, weakness, dizziness, blurred vision, fast heartbeat, sweating, tremor, trouble concentrating, confusion, or seizure (convulsions). Other side effects of Humulin N include injection site reactions (pain, redness, irritation). Tell your doctor if you have serious side effects of Humulin including signs of low potassium level in the blood (such as muscle cramps, weakness, irregular heartbeat).
Humulin N (insulin human recombinant) is administered by injection. Any change of insulin should be made cautiously and only under medical supervision. Changes in strength, manufacturer, type (e.g, regular, NPH, analog), species, or method of manufacture may result in the need to change dosage. Humulin N may interact with albuterol, clonidine, reserpine, guanethidine, or beta-blockers. Tell your doctor all medications and supplements you use. Humulin N (insulin human recombinant) should be used during pregnancy only if clearly needed. Tell your doctor if you are pregnant or plan to become pregnant during treatment. It is unknown if Humulin N passes into breast milk or if it could harm a nursing baby. Consult your doctor before breastfeeding.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Get emergency medical help if you have any of these signs of insulin allergy: itching skin rash over the entire body, wheezing, trouble breathing, fast heart rate, sweating, or feeling like you might pass out.
Hypoglycemia, or low blood sugar, is the most common side effect of insulin isophane. Symptoms of low blood sugar may include headache, nausea, hunger, confusion, drowsiness, weakness, dizziness, blurred vision, fast heartbeat, sweating, tremor, trouble concentrating, confusion, or seizure (convulsions). Watch for signs of low blood sugar. Carry a piece of non-dietetic hard candy or glucose tablets with you in case you have low blood sugar.
Tell your doctor if you have itching, swelling, redness, or thickening of the skin where you inject insulin isophane.
This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.

The following adverse reactions are discussed elsewhere in the labeling:
The following additional adverse reactions have been identified during post-approval use of HUMULIN N. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure.
Some patients taking HUMULIN N have experienced erythema, local edema, and pruritus at the site of injection. These conditions were usually self-limiting. Severe cases of generalized allergy (anaphylaxis) have been reported [see WARNINGS AND PRECAUTIONS].
Some patients taking HUMULIN N have experienced sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
Administration of insulin subcutaneously, including HUMULIN N, has resulted in lipoatrophy (depression in the skin) or lipohypertrophy (enlargement or thickening of tissue) [see DOSAGE AND ADMINISTRATION] in some patients.
Weight gain has occurred with some insulin therapies including HUMULIN N and has been attributed to the anabolic effects of insulin and the decrease in glycosuria.
Development of antibodies that react with human insulin have been observed with all insulin, including HUMULIN N.
