What is Humulin 70/30?
Humulin 70/30 contains a combination of insulin isophane and insulin regular. Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood. Insulin isophane is a intermediate-acting insulin. Insulin regular is an short-acting insulin. This combination insulin starts to work within 10 to 20 minutes after injection, peaks in 2 hours, and keeps working for up to 24 hours.
Humulin 70/30 is used to improve blood sugar control in adults with diabetes mellitus.
Humulin 70/30 may also be used for purposes not listed in this medication guide.
Do not use Humulin 70/30 if you are having an episode of hypoglycemia (low blood sugar).
Hypoglycemia, or low blood sugar, is the most common side effect of Humulin 70/30. Symptoms of low blood sugar may include headache, hunger, sweating, pale skin, irritability, dizziness, feeling shaky, or trouble concentrating. 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.
Never share an injection pen or syringe with another person, even if the needle has been changed.
Before taking this medicine
You should not use Humulin 70/30 if you are allergic to insulin, or if you are having an episode of hypoglycemia (low blood sugar).
Humulin 70/30 is not approved for use by anyone younger than 18 years old.
To make sure this medicine is safe for you, tell your doctor if you have:
liver or kidney disease; or
low levels of potassium in your blood (hypokalemia).
Tell your doctor if you also take pioglitazone or rosiglitazone (sometimes contained in combinations with glimepiride or metformin). Taking certain oral diabetes medicines while you are using insulin may increase your risk of serious heart problems.
Follow your doctor's instructions about using Humulin 70/30 if you are pregnant or breast-feeding a baby. Blood sugar control is very important during pregnancy, and your Humulin 70/30 dosage may be different during each trimester of pregnancy. Your dose needs may also be different while you are breast-feeding.
How should I take Humulin 70/30?
Use Humulin 70/30 exactly as it was prescribed for you. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Insulin is injected under the skin. You will be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes.
Humulin 70/30 must not be given with an insulin pump, or mixed with other insulins. Do not inject Humulin 70/30 into a vein or a muscle.
Your care provider will show you the best places on your body to inject Humulin 70/30. Use a different place each time you give an injection. Do not inject into the same place two times in a row.
After using Humulin 70/30, you should eat a meal within 30 to 45 minutes.
If you use an injection pen, use only the injection pen that comes with Humulin 70/30. Attach a new needle before each use. Do not transfer the insulin from the pen into a syringe.
Never share a Humulin 70/30 injection pen or syringe with another person, even if the needle has been changed. Sharing these devices can allow infections or disease to pass from one person to another.
Use a disposable needle or syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your insulin dose or schedule.
Insulin is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Keep Humulin 70/30 in its original container protected from heat and light. Do not draw insulin from a vial into a syringe until you are ready to give an injection. Do not freeze insulin or store it near the cooling element in a refrigerator. Throw away any insulin that has been frozen.
Storing unopened (not in use) Humulin 70/30:
Refrigerate and use until expiration date; or
Store at room temperature, and use the vial within 31 days or use the injection pen within 10 days.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Wear a diabetes medical alert tag in case of emergency. Any medical care provider who treats you should know that you have diabetes.

What other drugs will affect Humulin 70/30?
Many other medicines can affect your blood sugar, and some medicines can increase or decrease the effects of insulin. Some drugs can also cause you to have fewer symptoms of hypoglycemia, making it harder to tell when your blood sugar is low. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using. This includes prescription and over-the-counter medicines, vitamins, and herbal products.
