Precautions

Never share insulin needles or syringes with others under any circumstances. It is not safe for one pen to be used for more than one person. Sharing needles can result in transmission of hepatitis viruses, HIV, or other bloodborne illnesses.

It is very important that your doctor check your progress at regular visits, especially during the first few weeks you are using this medicine. Blood tests may be needed to check for unwanted effects.

It is very important to follow carefully any instructions from your health care team about:

• Alcohol—Drinking alcohol (including beer and wine) may cause severe low blood sugar. Discuss this with your health care team.
• Other medicines—Do not take other medicines during the time you are using this medicine unless they have been discussed with your doctor. This especially includes nonprescription medicines such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems.
• Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, patients with diabetes may need special counseling about diabetes medicine dosing changes that might occur because of lifestyle changes, such as changes in exercise and diet. Furthermore, counseling on contraception and pregnancy may be needed because of the problems that can occur in patients with diabetes during pregnancy.
• Travel—Keep a recent prescription and your medical history with you. Be prepared for an emergency as you would normally. Make allowances for changing time zones and keep your meal times as close as possible to your usual meal times.

In case of emergency: There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to:

• Wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says that you have diabetes and a list of all of your medicines.
• Keep an extra supply of insulin and syringes with needles or injection devices on hand in case high blood sugar occurs.
• Keep some kind of quick-acting sugar handy to treat low blood sugar.
• Have a glucagon kit and a syringe and needle available in case severe low blood sugar occurs. Check and replace any expired kits regularly.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, swelling of the face, tongue, and throat, trouble breathing, or chest pain after you get the injection.

Using this medicine together with other diabetes medicine (eg, thiazolidinedione [TZD] medicine) may cause serious heart problem or edema (fluid retention). Check with your doctor immediately if you are rapidly gaining weight, having, chest pain or discomfort, extreme tiredness or weakness, trouble breathing, uneven heartbeat, or excessive swelling of the hands, wrist, ankles, or feet.

You may have some skin redness, rash, itching, or swelling at the injection site. If this irritation is severe or does not go away, call your doctor. Do not inject this medicine into a skin area that is red, swollen, or itchy.

This medicine may make you dizzy, drowsy, or less alert than you are normally. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Too much insulin human regular can cause hypoglycemia (low blood sugar). Low blood sugar also can occur if you use insulin human regular with another antidiabetic medicine, changes in insulin regimen (eg, insulin strength, type of insulin, injection site), delay or miss a meal or snack, exercise more than usual, or drink alcohol. Symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people may feel different symptoms of low blood sugar. It is important that you learn which symptoms of low blood sugar you usually have so that you can treat it quickly.

Symptoms of low blood sugar include anxiety, behavior change similar to being drunk, blurred vision, cold sweats, confusion, difficulty in thinking, dizziness or lightheadedness, drowsiness, excessive hunger, fast heartbeat, headache, irritability or abnormal behavior, nervousness, nightmares, restless sleep, shakiness, slurred speech, and tingling in the hands, feet, lips, or tongue.

If symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes, or drink fruit juice, non diet soft drink, or sugar dissolved in water to relieve the symptoms. Also, check your blood for low blood sugar. Get to a doctor or a hospital right away if the symptoms do not improve. Someone should call for emergency help immediately if severe symptoms such as convulsions (seizures) or unconsciousness occur. Have a glucagon kit available, along with a syringe and needle, and know how to use it. Members of your household also should know how to use it.

Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your medicine, overeat or do not follow your meal plan, changes in insulin regimen, have a fever or infection, or do not exercise as much as usual. High blood sugar can be very serious and must be treated right away. It is important that you learn which symptoms you have in order to treat it quickly. Talk to your doctor about the best way to treat high blood sugar.

Symptoms of high blood sugar include blurred vision, drowsiness, dry mouth, flushed, dry skin, fruit-like breath odor, increased urination, ketones in the urine, loss of appetite, stomachache, nausea, or vomiting, tiredness, trouble breathing (rapid and deep), unconsciousness, and unusual thirst.

If symptoms of high blood sugar occur, check your blood sugar level and then call your doctor for instructions.

This medicine may cause low levels of potassium in your blood. Do not use medicines, supplements, or salt substitutes that contain potassium unless you have discussed this with your doctor.

For healthcare professionals

Applies to insulin regular: injectable solution, intravenous solution, subcutaneous solution.

General adverse events

Adverse reactions reported with this insulin include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, weight gain, and edema^[Ref]

Dermatologic

• Uncommon (0.1% to 1%): Lipodystrophy^[Ref]

Long-term use of insulin can cause lipodystrophy at the site of repeated insulin injections. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissues).^[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%): Anaphylactic reactions
• Postmarketing reports: Severe, life-threatening, generalized allergy, including anaphylaxis^[Ref]

Hypersensitivity reactions have included both local and systemic reactions. Anaphylaxis has been reported. Local reactions have presented as erythema, local edema, and pruritus at the injection site. Most minor reactions to insulin at the injection site resolve in a few days to a few weeks. In some instances these reactions have been caused by other factors such as irritants in a skin cleansing agent or poor injection technique. Localized reactions have been reported with metacresol, which is an excipient in many insulin products.

Generalized allergy to insulin may present as a whole body rash, dyspnea, wheezing, hypotension, tachycardia, or diaphoresis.^[Ref]

Immunologic

• Frequency not reported: Formation of anti-insulin antibodies^[Ref]

Increases in titers of anti-insulin antibodies that react with human insulin have been observed; some data indicates the increase is transient. The clinical significance of these antibodies is unknown; it does not appear to cause deterioration in glycemic control.^[Ref]

Cardiovascular

• Frequency not reported: Sodium retention and edema^[Ref]

Insulin may cause sodium retention and edema, especially with intensified insulin therapy. Combination use with thiazolidinediones has resulted in fluid retention which has led to or exacerbated heart failure.^[Ref]

Ocular

• Frequency not reported: Transitory, reversible ophthalmologic refraction disorder, worsening diabetic neuropathy^[Ref]

Transitory, reversible ophthalmologic refraction disorder and worsening of diabetic retinopathy has been reported with insulin initiation and glucose control intensification. Over the long-term, improved glycemic control decreases the risk for diabetic neuropathy.^[Ref]

Metabolic

• Very common (10% or more): Hypoglycemia
• Rare (less than 0.1%): Insulin resistance
• Frequency not reported: Hypokalemia, hyperglycemia, diabetic ketoacidosis, hyperosmolar hyperglycemic non-ketotic syndrome, hypomagnesemia, hypophosphatemia
• Postmarketing reports: Weight gain^[Ref]

Hypoglycemia is the most common adverse reaction of all insulin therapies. The timing of hypoglycemia generally reflects the time-action profile of the administered insulin, however, the time action profile of any insulin may vary considerably in different individuals or at different times in the same individual depending on dose, site of injection, blood supply, temperature, and physical activity. Other factors such as changes in food intake (timing of meals, amount or type of food) and concomitant medications will also affect the risk of hypoglycemia.

Hypokalemia, which is due to a shift in potassium from the extracellular to the intracellular space, occurs with all insulins. Hypokalemia and hypomagnesemia has been reported, particularly in patients treated for diabetic ketoacidosis (DKA). Insulin increases the intracellular transport of phosphate, which often results in hypophosphatemia during treatment of DKA. In situations in which not enough insulin is available to control blood glucose, hyperglycemia, diabetic ketoacidosis, and hyperosmolar hyperglycemic non-ketotic syndrome may occur.

Weight gain has been reported and has been attributed to the anabolic effects of insulin and the decrease in glucosuria.^[Ref]

Local

• Common (1% to 10%): Injection site hypertrophy
• Frequency not reported: Injection site reactions^[Ref]

Injection site reactions including pain, redness, hives, inflammation, bruising, swelling, and itching have occurred. These usually resolve in a few days to a few weeks; rotation of the injection site reduces the risk of these reactions developing.^[Ref]

Nervous system

• Frequency not reported: Acute painful peripheral neuropathy^[Ref]

Acute painful peripheral neuropathy has been reported with insulin initiation and glucose control intensification. Over the long-term, improved glycemic control decreases the risk for neuropathy.^[Ref]

Other

• Frequency not reported: Weight gain^[Ref]

Weight gain can occur with insulin use; it is believed to be due to the anabolic effects of insulin and the decrease in glucosuria.^[Ref]
