Lantus (insulin glargine [rdna origin]) Injection is used to treat type 1 (insulin-dependent) or type 2 (non insulin-dependent) diabetes. It is a man-made form of a hormone that is produced in the body. Common side effects include pain, redness, swelling or itching at the injection site. These effects usually go away after a few days or weeks.
Lantus should be administered subcutaneously (under the skin) once a day at the same time every day. Dose is determined by the individual and the desired blood glucose levels. Lantus may interact with albuterol, clonidine, reserpine, or beta-blockers. Many other medicines can increase or decrease the effects of insulin glargine on lowering your blood sugar. Tell your doctor all prescription and over-the-counter medications and supplements you use. Tell your doctor if you are pregnant before using Lantus. Discuss a plan to manage blood sugar with your doctor before becoming pregnant. Your doctor may switch the type of insulin you use during pregnancy. It is unknown if this drug passes into breast milk. Insulin needs may change while breast-feeding. Consult your doctor before breast-feeding.

Lantus Overview - Patient Information: Side Effects
Pain, redness, swelling or itching at the injection site may occur. These effects usually go away after a few days or weeks. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Too much insulin can cause low blood sugar (hypoglycemia). This effect may also occur if you do not consume enough calories. The symptoms include chills, cold sweats, blurred vision, dizziness, drowsiness, shaking, fast heartbeat, weakness, headache, fainting, tingling of the hands/feet, or hunger. It is a good habit to carry glucose (sugar) tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, raise your blood sugar quickly by eating a quick source of sugar such as table sugar, honey, candy, or drinking a glass of fruit juice or non-diet soda. Tell your doctor immediately about the reaction. To help prevent low blood sugar, eat meals on a regular schedule and do not skip meals.
Too little insulin can cause high blood sugar (hyperglycemia). Symptoms of high blood sugar include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, or fruity breath odor. If these symptoms occur, tell your doctor immediately. Your treatment plan may need to be changed.
This medication may cause low potassium levels in the blood (hypokalemia). Tell your doctor immediately if any of these unlikely but serious side effects occur: muscle cramps, weakness, irregular heartbeat.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Lantus FDA Prescribing Information: Side Effects
(Adverse Reactions)
SIDE EFFECTS
The adverse events commonly associated with LANTUS (insulin glargine [rdna origin] injection) include the following:
Body as a whole: allergic reactions (see PRECAUTIONS).
Skin and appendages: injection site reaction, lipodystrophy, pruritus, rash (see PRECAUTIONS).
Other: hypoglycemia (see WARNINGS and PRECAUTIONS).
In clinical studies in adult patients, there was a higher incidence of treatment-emergent injection site pain in LANTUS (insulin glargine [rdna origin] injection) -treated patients (2.7%) compared to NPH insulin-treated patients (0.7%).
The reports of pain at the injection site were usually mild and did not result in discontinuation of therapy. Other treatment-emergent injection site reactions occurred at similar incidences with both insulin glargine and NPH human insulin.
Retinopathy was evaluated in the clinical studies by means of retinal adverse events reported and fundus photography. The numbers of retinal adverse events reported for LANTUS (insulin glargine [rdna origin] injection) and NPH treatment groups were similar for patients with type 1 and type 2 diabetes. Progression of retinopathy was investigated by fundus photography using a grading protocol derived from the
Early Treatment Diabetic Retinopathy Study (ETDRS). In one clinical study involving patients with type 2 diabetes, a difference in the number of subjects with ≥ 3-step progression in ETDRS scale over a 6-month period was noted by fundus photography (7.5% in LANTUS (insulin glargine [rdna origin] injection) group versus 2.7% in NPH treated group). The overall relevance of this isolated finding cannot be determined due to the small number of patients involved, the short follow-up period, and the fact that this finding was not observed in other clinical studies.
