Lantus (Insulin Glargine, rDNA origin)
Lantus is a medicine that is a long-acting insulin. Lantus is used to control high blood sugar in people with diabetes. Lantus is available as a prefilled pen, vial, and a cartridge.
Do not change the type of insulin you use unless told to do so by your doctor. Your insulin dose and the time you take your dose can change with different types of insulin. Make sure you have the right type and strength of insulin prescribed for you.
Do not make any changes to your insulin dose unless you have talked to your doctor. Your insulin needs may change because of illness, stress, other medicines, or changes in your diet or activity level.
Lantus can cause you to experience low blood sugar. Therefore, it is important to use it as prescribed by your doctor. Symptoms of low blood sugar include: anxiety, restlessness, trouble concentrating, changes in your personality or mood, blurred vision, dizziness, shakiness, lightheadedness, drowsiness, nightmares or trouble sleeping, sweating, irritability, headache, slurred speech, fast heartbeat, unsteady walking, or tingling in your hands, feet, lips, or tongue. Always carry a quick source of sugar to treat low blood sugar (such as glucose tablets, hard candy, or juice).
If you forget to take your dose of Lantus, your blood sugar may get too high. If your high blood sugar is not treated, it can lead to serious problems (such as passing out or loss of consciousness, coma, or even death). Follow your doctor’s instructions for treating high blood sugar. Symptoms of high blood sugar include: confusion, increased thirst, frequent urination, drowsiness, loss of appetite, difficulty breathing, fruity smelling breath, nausea, vomiting, or stomach ache.
Lantus can cause serious and possibly life-threatening allergic reactions. Get medical help right away if you experience shortness of breath, wheezing, a fast heartbeat, sweating, low blood pressure, or develop a rash all over your body.
