Evening

  • Give 1/3 of daily insulin SC

Administration

Administer within 15 min before a meal or immediately after a meal

Store unopened vials/pens refrigerated; do not freeze

Opened (in-use) product may be stored at ambient room temperature (below 86°F [30°C]) and away from heat and light

Dosage Adjustment Strategies

Dosage of human insulin, which is always expressed in USP units, must be based on the results of blood and urine glucose tests and must be carefully individualized to optimal effect

Dose adjustments should be based on regular blood glucose testing (See Dosage Adjustment Strategies)

Adjust to achieve appropriate glucose control

Look for consistent pattern in blood sugars for >3 days

  • Compare blood glucose for same time each day
  • For each time of day: calculate blood glucose range
  • Calculate median blood glucose
  • Consider eating and activity patterns during day

Adjust only one insulin dose at a time

  • Correct hypoglycemia first
  • Correct highest blood sugars next
  • If all blood sugars are high (within 2.75 mmol/L [50 mg/dL]): correct morning fasting blood glucose 1st
  • Many sliding scales exist to determine exact insulin dose based on frequent blood glucose monitoring
  • - Commonly written for q4hr blood glucose test
  • - Sliding scale coverage usually begins after blood glucose >11 mmol/L (200 mg/dL)
  • - If coverage is needed q4hr x 24 hr, then base insulin dose is adjusted first; sliding scale doses may be adjusted upwards as well
  • Change insulin doses in small increments
  • - Type I diabetes: 1-2 U change
  • - Type II diabetes: 2-3 U change

                • Repeated insulin injections into areas of lipodystrophy or localized cutaneous amyloidosis reported to result in hyperglycemia; a sudden change in the injection site (to unaffected area) has been reported to result in hypoglycemia
                • Make any changes to a patient’s insulin regimen under close medical supervision with increased frequency of blood glucose monitoring
                • Advise patients who have repeatedly injected into areas of lipodystrophy or localized cutaneous amyloidosis to change injection site to unaffected areas and closely monitor for hypoglycemia
                • For patients with type 2 diabetes, dosage adjustments in concomitant oral antidiabetic treatment may be needed

                Pregnancy & Lactation

                Pregnancy

                Available data from published studies over decades have not established association with human insulin use during pregnancy and major birth defects, miscarriage or adverse maternal or fetal Outcomes; there are risks to mother and fetus associated with poorly controlled diabetes in pregnancy; animal reproduction studies were not performed

                Poorly controlled diabetes in pregnancy increases maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, stillbirth, and delivery complications; poorly controlled diabetes increases fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity

                Lactation

                Available data from published literature suggests that exogenous human insulin products, are transferred into human milk; there are no adverse reactions reported in breastfed infants in the literature; there are no data on effects of exogenous human insulin products, on milk production; the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy, and any potential adverse effects on breastfed infant from drug, or from underlying maternal condition

                Pregnancy Categories

                A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                NA: Information not available.

                Mechanism of Action

                Regulates glucose metabolism

                Insulin and its analogs lower blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production; insulin inhibits lipolysis and proteolysis, and enhances protein synthesis

                Insulin NPH and insulin regular is a combination insulin product with intermediate duration that has more rapid onset than that of insulin NPH alone

                Pharmacokinetics

                Onset: 1-1.5 hr (NPH); 0.5 hr (regular)

                Peak: 4-12 hr (NPH); 2.5-5 hr (regular)

                Duration: Up to 24 hr (NPH); 8 hr (regular)

                Bioavailability: IM, SC, IP: well absorbed

                Protein Bound: 5% (not bound to serum binding-protein, but present as a monomer in plasma)

                Vd: 0.15 L/kg

                Metabolism: Liver >50%; kidney 30%; adipose tissue/muscle 20%

                insulin NPH and regular human subcutaneous

                INSULIN HUMAN ISOPHANE SUSPENSION 70/REGULAR 30 - INJECTION

                (IN-su-lin HUE-man EYE-soe-fane 70/Regular 30)

                COMMON BRAND NAME(S): Humulin 70-30, Novolin 70-30

                USES: Combination isophane/regular insulin is used with a proper diet and exercise program to control high blood sugar in people with diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke.This man-made insulin product is the same as human insulin. It replaces the insulin that your body would normally make. It is a mixture of 70% intermediate-acting insulin (isophane) and 30% short-acting insulin (regular). It starts to work as quickly as regular insulin but lasts longer. This insulin product works by helping blood sugar (glucose) get into cells so your body can use it for energy. This product may be used alone or with other oral diabetes drugs (such as metformin).

                HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using combination isophane/regular insulin and each time you get a refill. If you have any questions, ask your doctor, diabetes educator, or pharmacist.Learn all preparation and usage instructions from your health care professional and the product package.Before using, gently roll the vial or cartridge, turning it upside down and back 10 times to mix the medication. Do not shake the container. Check this product visually for particles or discoloration. If either is present, do not use the insulin. Combination isophane/regular insulin should look evenly cloudy/milky after mixing. Do not use if you see clumps of white material, a "frosty" appearance, or particles stuck to the sides of the vial or cartridge.Before injecting each dose, clean the injection site with rubbing alcohol. Change where you inject each time to lessen the risk of problems or damage under the skin (for example, pits/lumps or thickened skin). Inject this medication under the skin as directed by your doctor, usually once or twice a day. This insulin product may be injected in the stomach area, the thigh, the buttocks, or the back of the upper arm. Do not inject into a vein or muscle because very low blood sugar (hypoglycemia) may occur. Do not rub the area after the injection. Do not inject into skin that is red, swollen, itchy, or damaged. Do not inject cold insulin because this can be painful. The insulin container you are currently using can be kept at room temperature.This product should not be mixed with any other insulin.Do not change brands or types of insulin without directions on how to do so from your doctor.Do not share your pen device with another person, even if the needle is changed. You may give other people a serious infection, or get a serious infection from them. Learn how to store and discard medical supplies safely.The dosage is based on your medical condition and response to treatment. Measure each dose very carefully because even small changes in the amount of insulin may have a large effect on your blood sugar.Check your blood sugar regularly as directed by your doctor. Keep track of your results and share them with your doctor. This is very important in order to determine the correct insulin dose.Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day.Tell your doctor if your condition does not improve or if it worsens (your blood sugar is too high or too low).

                SIDE EFFECTS: Injection site reactions (such as pain, redness, irritation) or weight gain may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: signs of low potassium level in the blood (such as muscle cramps, weakness, irregular heartbeat).This medication can cause low blood sugar (hypoglycemia). This may occur if you do not consume enough calories from food or if you do unusually heavy exercise. Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor right away about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your dosage may need to be increased.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects.

Talk to your pharmacist for more details.Do not use this medication when you have low blood sugar (hypoglycemia).Before using this medication, tell your doctor or pharmacist your medical history, especially of: adrenal/pituitary gland problems, kidney disease, liver disease, thyroid problems.You may experience blurred vision, dizziness, or drowsiness due to extremely low or high blood sugar. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely.Limit alcohol while using this medication because it can increase your risk of developing low blood sugar.It may be harder to control your blood sugar when your body is stressed (such as due to fever, infection, injury, or surgery). Consult your doctor because this may require a change in your treatment plan, medications, or blood sugar testing.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Check your blood sugar before and after exercise. You may need a snack before exercising.If traveling across time zones, ask your doctor about how to adjust your insulin schedule. Take extra insulin and supplies with you.Older adults may be more sensitive to the side effects of this drug, especially low blood sugar.Children may be more sensitive to the side effects of this drug, especially low blood sugar.Tell your doctor right away if you are pregnant. Pregnancy may cause or worsen diabetes. Discuss a plan with your doctor for managing your blood sugar while pregnant. Your doctor may change your diabetes treatment during your pregnancy (such as diet and medications including insulin).This medication passes into breast milk, but is unlikely to harm a nursing infant.
