Before taking this medicine

Tell your doctor if you have ever had:

  • low levels of potassium in your blood (hypokalemia).

Tell your doctor if you also take pioglitazone or rosiglitazone (sometimes found in combinations with glimepiride or metformin). Taking certain oral diabetes medicines while you are using insulin may increase your risk of serious heart problems.

Insulin is injected under the skin. A healthcare provider can teach you how to properly use the medication by yourself.

Do not give ReliOn/Novolin 70/30 with an insulin pump.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.

This insulin should look cloudy after mixing. Do not use the mixture if it looks clear or has particles in it. Call your pharmacist for new medicine.

Your care provider will show you where on your body to inject ReliOn/Novolin 70/30. Use a different place each time you give an injection. Do not inject into the same place two times in a row.

If you use an injection pen, use only the injection pen that comes with this insulin. Attach a new needle before each use. Do not transfer the insulin from the pen into a syringe.

Never share an 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.

You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).

Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or 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.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication 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.
