Rarely, Lantus (insulin glargine) can cause severe allergic reactions that can be life threatening. Go to the emergency room right away if you suddenly have problems breathing, a blistering skin rash with a high fever, or if you feel your face, mouth, or throat swell up.
What are the side effects of Lantus?Low blood sugar levels (hypoglycemia) are the most common side effect of Lantus. The risk of hypoglycemia increases with tighter blood sugar controls, changes in meal patterns, certain coadministered medications, and changes in physical activity levels. People with liver or kidney disease may be at a higher risk of hypoglycemia.
How is Lantus insulin glargine administered?For proper use, inject Lantus (insulin glargine) under your skin (subcutaneously) in your upper arm, abdomen (stomach area), or thigh (upper leg). Never inject it into a vein or muscle. This can cause severely low blood sugar levels and infections.
What is Lantus used for?Lantus, Humalog, and Novolog are used to help control blood sugar levels in people who have type 1 or type 2 diabetes. Victoza is used to help control blood sugar levels only in people with type 2 diabetes. Lantus is a long-acting insulin that contains the active drug insulin glargine. Humalog and Novolog are fast-acting insulins.
