High-Alert Medications - NovoLog (insulin aspart)

 

Extra care is needed because NovoLog is a high-alert medicine.

High-alert medicines have been proven to be safe and effective. But these medicines can cause serious injury if a mistake happens while taking them. This means that it is very important for you to know about this medicine and take it exactly as directed.

Top 10 List of Safety Tips for NovoLog

When taking your medicine
1. Know your insulin. NovoLog is a rapid-acting form of insulin that should be injected below the skin 5 to 10 minutes before meals. Have food ready before injection. After injecting the insulin, do not skip a meal or delay eating.
2. Prepare your insulin. An intermediate- or long-acting insulin is often prescribed with NovoLog. NovoLog can be mixed with insulin NPH (intermediate-acting insulin), but always draw NovoLog into the syringe first. Never mix NovoLog with Lantus. Do not mix NovoLog with other insulins if using an insulin pen or external pump. Do not vigorously shake insulin before use.
3. Don't reuse or recycle. Dispose of used syringes/needles, pens, and lancets in a sealable hard plastic or metal container (e.g., empty detergent bottle, special sharps container from your pharmacy). When the container is full, seal the lid before placing it in the trash. Do not reuse or recycle syringes/needles or lancets.
4. Don't share. Even if you change the needle, sharing an insulin pen or syringe may spread diseases carried in the blood, including hepatitis and HIV.
To avoid serious side effects
5. Avoid mix-ups. If you use more than one type of insulin, make each vial or pen look different by putting a rubber band around one type of insulin.
6. Check your medicine. NovoLog can be confused with Humalog (another rapid-acting insulin). When you pick up your insulin at the pharmacy, be sure it's the right type of insulin.
7. Treat low blood sugar (hypoglycemia). Carry a quick source of sugar, such as glucose tablets, candy, or juice, to treat low blood sugar. Signs of low blood sugar are listed below.
8. Test your blood sugar level. Ask your doctor how often you should test your blood sugar level. Keep a log of your blood sugar levels and how much insulin you take each day. Bring the log with you each time you visit your doctor.
9. Get a periodic lab test. You should have a hemoglobin A1c test at least twice a year to determine how well your diabetes is being controlled. The test shows an average of your blood sugar control over a 6- to 12-week period. Your goal is a hemoglobin A1c of 7% or less.
When you should call your doctor
10. Call for illness or changes in habits. Your insulin needs may change because of illness, stress, changes in eating habits or physical activity, and other medicines you take. Call your doctor if you experience these conditions. Never change your insulin dose unless advised by your doctor.

Signs of hypoglycemia (low blood sugar)

  • hunger
  • feeling shaky
  • fast heartbeat
  • lightheadedness
  • dizziness
  • sweating
  • headache
  • confusion
  • irritability

Hypoglycemia is caused by too much insulin or increased work or exercise without eating. Symptoms of hypoglycemia may be different for each person and can change from time to time. Hypoglycemia can affect your ability to think and react quickly, so driving a car could be risky. Severe hypoglycemia can lead to loss of consciousness, seizures, brain damage, or even death. Know the symptoms of hypoglycemia and treat it quickly by drinking juice or a sugar-containing beverage, or eating sugar or candy. Talk to your doctor if hypoglycemia is a problem for you.
