Extra care is needed because Lantus 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 Lantus
When taking your medicine
Know your insulin. Lantus is a long-acting insulin that should be injected below the skin once daily as directed by your doctor. On rare occasions, your physician may direct you to take Lantus two times daily. Take Lantus the same time every day.
Prepare your insulin. A rapid- or short-acting insulin is often prescribed with Lantus. However, Lantus should never be mixed in the same syringe with other insulins before injection. Do not vigorously shake insulin before use.
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, sharps container from your pharmacy). When the container is full, seal the lid and discard the container according to your community guidelines (www.safeneedledisposal.org). Do not reuse or recycle syringes/needles or lancets.
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
Avoid mix-ups. List If you use more than one type of insulin, make sure each vial or pen looks different to avoid mix-ups. Lantus is a long-acting insulin that may look like a rapid- or short-acting insulin. For example, Lantus and Apidra (a rapid-acting insulin) are both clear medicines in elongated vials (or insulin pens) that look similar. To make them look different, put a rubber band around one type of insulin.
Check your medicine. There are many types of insulins that come in similar looking vials, cartons, or pens. When you pick up your insulin at the pharmacy, be sure it's the right type of insulin.
Treat low blood sugar (hypoglycemia). Always 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.
Test your blood sugar. Ask your doctor how often you should test your blood sugar. Keep a log of your blood sugar levels and how much insulin you take each day. Bring the log each time you visit the doctor.
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
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)
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.
