humulin 50/50 (Insulin human) injection, suspension
[Eli Lilly and Company]
THIS LILLY HUMAN INSULIN PRODUCT DIFFERS FROM ANIMAL–SOURCE INSULINS BECAUSE IT IS STRUCTURALLY IDENTICAL TO THE INSULIN PRODUCED BY YOUR BODY’S PANCREAS AND BECAUSE OF ITS UNIQUE MANUFACTURING PROCESS.
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 FOR A CHANGE IN DOSAGE.
SOME PATIENTS TAKING HUMULIN® (HUMAN INSULIN, rDNA ORIGIN) MAY REQUIRE A CHANGE IN DOSAGE FROM THAT USED WITH OTHER INSULINS. IF AN ADJUSTMENT IS NEEDED, IT MAY OCCUR WITH THE FIRST DOSE OR DURING THE FIRST SEVERAL WEEKS OR MONTHS.
Insulin is a hormone produced by the pancreas, a large gland that lies near the stomach. This hormone is necessary for the body’s correct use of food, especially sugar. Diabetes occurs when the pancreas does not make enough insulin to meet your body’s needs.
To control your diabetes, your doctor has prescribed injections of insulin products to keep your blood glucose at a near–normal level. You have been instructed to test your blood and/or your urine regularly for glucose. Studies have shown that some chronic complications of diabetes such as eye disease, kidney disease, and nerve disease can be significantly reduced if the blood sugar is maintained as close to normal as possible. The American Diabetes Association recommends that if your pre–meal glucose levels are consistently above 130 mg/dL or your hemoglobin A1c (HbA1c) is more than 7%, you should talk to your doctor. A change in your diabetes therapy may be needed. If your blood tests consistently show below–normal glucose levels, you should also let your doctor know. Proper control of your diabetes requires close and constant cooperation with your doctor. Despite diabetes, you can lead an active and healthy life if you eat a balanced diet, exercise regularly, and take your insulin injections as prescribed by your doctor.
Always keep an extra supply of insulin as well as a spare syringe and needle on hand. Always wear diabetic identification so that appropriate treatment can be given if complications occur away from home.
50/50 HUMAN INSULIN
Humulin is synthesized in a special non–disease–producing laboratory strain of Escherichia coli bacteria that has been genetically altered to produce human insulin. Humulin 50/50 is a mixture of 50% Human Insulin Isophane Suspension and 50% Human Insulin Injection (rDNA origin). It is an intermediate-acting insulin combined with the more rapid onset of action of Regular human insulin. The duration of activity may last up to 24 hours following injection. The time course of action of any insulin may vary considerably in different individuals or at different times in the same individual. As with all insulin preparations, the duration of action of Humulin 50/50 is dependent on dose, site of injection, blood supply, temperature, and physical activity. Humulin 50/50 is a sterile suspension and is for subcutaneous injection only. It should not be used intravenously or intramuscularly. The concentration of Humulin 50/50 is 100 units/mL (U–100).
Human insulin from Eli Lilly and Company has the trademark Humulin. Your doctor has prescribed the type of insulin that he/she believes is best for you.
DO NOT USE ANY OTHER INSULIN EXCEPT ON YOUR DOCTOR’S ADVICE AND DIRECTION.
Always check the carton and the bottle label for the name and letter designation of the insulin you receive from your pharmacy to make sure it is the same as prescribed by your doctor.
Always check the appearance of your bottle of Humulin 50/50 before withdrawing each dose. Before each injection the Humulin 50/50 bottle must be carefully shaken or rotated several times to completely mix the insulin. Humulin 50/50 suspension should look uniformly cloudy or milky after mixing. If not, repeat the above steps until contents are mixed.
Do not use Humulin 50/50:
if the insulin substance (the white material) remains at the bottom of the bottle after mixing or
if there are clumps in the insulin after mixing, or
if solid white particles stick to the bottom or wall of the bottle, giving a frosted appearance.
If you see anything unusual in the appearance of Humulin 50/50 suspension in your bottle or notice your insulin requirements changing, talk to your doctor.
Not in-use (unopened): Humulin 50/50 bottles not in-use should be stored in a refrigerator, but not in the freezer.
In-use (opened): The Humulin 50/50 bottle you are currently using can be kept unrefrigerated as long as it is kept as cool as possible [below 86°F (30°C)] away from heat and light.
Do not use Humulin 50/50 after the expiration date stamped on the label or if it has been frozen.
INSTRUCTIONS FOR INSULIN VIAL USE
NEVER SHARE NEEDLES AND SYRINGES.
Correct Syringe Type
Doses of insulin are measured in units. U–100 insulin contains 100 units/mL (1 mL=1 cc). With Humulin 50/50, it is important to use a syringe that is marked for U–100 insulin preparations. Failure to use the proper syringe can lead to a mistake in dosage, causing serious problems for you, such as a blood glucose level that is too low or too high.
To help avoid contamination and possible infection, follow these instructions exactly.
Disposable syringes and needles should be used only once and then discarded by placing the used needle in a puncture-resistant disposable container. Properly dispose of the puncture-resistant container as directed by your Health Care Professional.
Preparing the Dose
Wash your hands.
Carefully shake or rotate the bottle of insulin several times to completely mix the insulin.
Inspect the insulin. Humulin 50/50 suspension should look uniformly cloudy or milky. Do not use Humulin 50/50 if you notice anything unusual in its appearance.
If using a new Humulin 50/50 bottle, flip off the plastic protective cap, but do not remove the stopper. Wipe the top of the bottle with an alcohol swab.
Draw an amount of air into the syringe that is equal to the Humulin 50/50 dose. Put the needle through rubber top of the Humulin 50/50 bottle and inject the air into the bottle.
Turn the Humulin 50/50 bottle and syringe upside down. Hold the bottle and syringe firmly in one hand and shake gently.
Making sure the tip of the needle is in the Humulin 50/50 suspension, withdraw the correct dose of Humulin 50/50 into the syringe.
Before removing the needle from the Humulin 50/50 bottle, check the syringe for air bubbles. If bubbles are present, hold the syringe straight up and tap its side until the bubbles float to the top. Push the bubbles out with the plunger and then withdraw the correct dose.
Remove the needle from the bottle and lay the syringe down so that the needle does not touch anything.
To avoid tissue damage, choose a site for each injection that is at least 1/2 inch from the previous injection site. The usual sites of injection are abdomen, thighs, and arms.
Cleanse the skin with alcohol where the injection is to be made.
With one hand, stabilize the skin by spreading it or pinching up a large area.
Insert the needle as instructed by your doctor.
Push the plunger in as far as it will go.
Pull the needle out and apply gentle pressure over the injection site for several seconds. Do not rub the area.
Place the used needle in a puncture-resistant disposable container and properly dispose of the puncture-resistant container as directed by your Health Care Professional.
Your doctor has told you which insulin to use, how much, and when and how often to inject it. Because each patient’s diabetes is different, this schedule has been individualized for you. Your usual dose of Humulin 50/50 may be affected by changes in your diet, activity, or work schedule. Carefully follow your doctor’s instructions to allow for these changes. Other things that may affect your Humulin 50/50 dose are:
Illness, especially with nausea and vomiting, may cause your insulin requirements to change. Even if you are not eating, you will still require insulin. You and your doctor should establish a sick day plan for you to use in case of illness. When you are sick, test your blood glucose frequently. If instructed by your doctor, test your ketones and report the results to your doctor.
Good control of diabetes is especially important for you and your unborn baby. Pregnancy may make managing your diabetes more difficult. If you are planning to have a baby, are pregnant, or are nursing a baby, talk to your doctor.
Insulin requirements may be increased if you are taking other drugs with blood–glucose–raising activity, such as oral contraceptives, corticosteroids, or thyroid replacement therapy. Insulin requirements may be reduced in the presence of drugs that lower blood glucose or affect how your body responds to insulin, such as oral antidiabetic agents, salicylates (for example, aspirin), sulfa antibiotics, alcohol, certain antidepressants and some kidney and blood pressure medicines. Your Health Care Professional may be aware of other medications that may affect your diabetes control. Therefore, always discuss any medications you are taking with your doctor.
Exercise may lower your body’s need for insulin during and for some time after the physical activity. Exercise may also speed up the effect of an insulin dose, especially if the exercise involves the area of injection site (for example, the leg should not be used for injection just prior to running). Discuss with your doctor how you should adjust your insulin regimen to accommodate exercise.
When traveling across more than 2 time zones, you should talk to your doctor concerning adjustments in your insulin schedule.
COMMON PROBLEMS OF DIABETES
Hypoglycemia (Low Blood Sugar)
Hypoglycemia (too little glucose in the blood) is one of the most frequent adverse events experienced by insulin users. It can be brought about by:
Missing or delaying meals.
Taking too much insulin.
Exercising or working more than usual.
An infection or illness associated with diarrhea or vomiting.
A change in the body’s need for insulin.
Diseases of the adrenal, pituitary, or thyroid gland, or progression of kidney or liver disease.
Interactions with certain drugs, such as oral antidiabetic agents, salicylates (for example, aspirin), sulfa antibiotics, certain antidepressants and some kidney and blood pressure medicines.
Consumption of alcoholic beverages.
Symptoms of mild to moderate hypoglycemia may occur suddenly and can include:
Signs of severe hypoglycemia can include:
Therefore, it is important that assistance be obtained immediately.
Early warning symptoms of hypoglycemia may be different or less pronounced under certain conditions, such as long duration of diabetes, diabetic nerve disease, use of medications such as beta–blockers, changing insulin preparations, or intensified control (3 or more insulin injections per day) of diabetes.
A few patients who have experienced hypoglycemic reactions after transfer from animal–source insulin to human insulin have reported that the early warning symptoms of hypoglycemia were less pronounced or different from those experienced with their previous insulin.
Without recognition of early warning symptoms, you may not be able to take steps to avoid more serious hypoglycemia. Be alert for all of the various types of symptoms that may indicate hypoglycemia. Patients who experience hypoglycemia without early warning symptoms should monitor their blood glucose frequently, especially prior to activities such as driving. If the blood glucose is below your normal fasting glucose, you should consider eating or drinking sugar–containing foods to treat your hypoglycemia.
Mild to moderate hypoglycemia may be treated by eating foods or drinks that contain sugar. Patients should always carry a quick source of sugar, such as hard candy or glucose tablets. More severe hypoglycemia may require the assistance of another person. Patients who are unable to take sugar orally or who are unconscious require an injection of glucagon or should be treated with intravenous administration of glucose at a medical facility.
You should learn to recognize your own symptoms of hypoglycemia. If you are uncertain about these symptoms, you should monitor your blood glucose frequently to help you learn to recognize the symptoms that you experience with hypoglycemia.
If you have frequent episodes of hypoglycemia or experience difficulty in recognizing the symptoms, you should talk to your doctor to discuss possible changes in therapy, meal plans, and/or exercise programs to help you avoid hypoglycemia.
Hyperglycemia (High Blood Sugar) and Diabetic Ketoacidosis (DKA)
Hyperglycemia (too much glucose in the blood) may develop if your body has too little insulin. Hyperglycemia can be brought about by any of the following:
Omitting your insulin or taking less than your doctor has prescribed.
Eating significantly more than your meal plan suggests.
Developing a fever, infection, or other significant stressful situation.
In patients with type 1 or insulin–dependent diabetes, prolonged hyperglycemia can result in DKA (a life-threatening emergency). The first symptoms of DKA usually come on gradually, over a period of hours or days, and include a drowsy feeling, flushed face, thirst, loss of appetite, and fruity odor on the breath. With DKA, blood and urine tests show large amounts of glucose and ketones. Heavy breathing and a rapid pulse are more severe symptoms. If uncorrected, prolonged hyperglycemia or DKA can lead to nausea, vomiting, stomach pain, dehydration, loss of consciousness, or death. Therefore, it is important that you obtain medical assistance immediately.
Rarely, administration of insulin subcutaneously can result in lipoatrophy (seen as an apparent depression of the skin) or lipohypertrophy (seen as a raised area of the skin). If you notice either of these conditions, talk to your doctor. A change in your injection technique may help alleviate the problem.
Local Allergy — Patients occasionally experience redness, swelling, and itching at the site of injection. This condition, called local allergy, usually clears up in a few days to a few weeks. In some instances, this condition may be related to factors other than insulin, such as irritants in the skin cleansing agent or poor injection technique. If you have local reactions, talk to your doctor.
Systemic Allergy — Less common, but potentially more serious, is generalized allergy to insulin, which may cause rash over the whole body, shortness of breath, wheezing, reduction in blood pressure, fast pulse, or sweating. Severe cases of generalized allergy may be life threatening. If you think you are having a generalized allergic reaction to insulin, call your doctor immediately.
