Insulin glargine, recombinant is a long-acting form of insulin that works slowly, over a period of 24 hours. Naturally secreted by the islets of Langerhans in the pancreas, insulin is one of the hormones that helps the body convert food into energy. This is achieved by using the glucose in the blood as quick energy. Additionally, insulin helps the body store extra energy for later use. An individual suffering from diabetes mellitus cannot produce enough insulin or does not use insulin properly. This results in high blood sugar levels. Like other forms of insulin, insulin glargine is taken in combination with other forms of insulin or with oral diabetes medications to regulate the blood sugar levels.
Produced under brand names Basaglar, Lantus, Lantus SoloStar, and TouJeo, insulin glargine is available only with the doctor's prescription. Administered subcutaneously, insulin glargine has a low aqueous solubility at pH 7 (neutral pH). However, it is completely soluble at pH 4. Upon administration, the acidic solution is neutralized resulting in the formation of microprecipitates from which small doses of insulin glargine are slowly released into the body. This results in a fairly constant concentration/time profile over 24 hours with no noticeable peak. This constant profile allows insulin glargine to be administered as a daily basal insulin dosage.
Along with the desired effects, insulin glargine may cause some unwanted effects on the body. While the side effects vary from patient to patient, you may want to contact your healthcare provider if some of these side effects become severe and life-threatening.
Check with your healthcare provider or the emergency room immediately if you are worried about these insulin glargine side effects:
Some insulin glargine side effects are mild and may not need medical attention since they always go away as the body adjusts to the medication.

However, you may check with your healthcare provider if any of these side effects persist or are bothersome:
A nurse or trained healthcare provider may administer insulin glargine. You may also learn how to self-medicate at home. As already indicated, this medication is injected under the skin. Do NOT inject this medication into the vein or muscle.
If self-medicating, always double-check both the strength (concentration) of your insulin as well as your prescribed dosage. Remember, concentration and dose do not mean the same thing. Dosage refers to the number of units of insulin you are to use while concentration refers to the number of units present in each milliliter (mL), such as 100units/mL (U-100). This does not necessarily mean you will have to use 100 units at a time.
Each package of insulin glargine, recombinant comes with the patient's information sheet. It is important that you read and understand the following:
It is best to inject the medication into different parts of the body each time you treat yourself (e.g under the skin on your arm, thigh, stomach or abdomen). Ask your healthcare provider any questions you might have with respect to self-medication.

If your hypoglycemia becomes extreme and cannot drink or eat, use a glucagon injection. Your healthcare provider may prescribe for you a glucagon emergency kit with instruction on how to inject yourself.
Additionally, watch out for signs of extremely high blood sugar levels (hyperglycemia). These may include increased urination, hunger, frequent thirst, dryness of mouth, persistent drowsiness, blurred vision, a feeling of fruity breath odor, dryness of the skin and rapid weight loss.

Insulin glargine, recombinant is a synthetic form of a hormone that is naturally produced by the beta cells in the islets of Langerhans in the pancreas. It works by regulating the blood's glucose (sugar) levels. Additionally, insulin helps the body store up energy for later use. Type 2 diabetes hinders the body's natural ability to produce insulin or the ability of the produced insulin to work properly. This causes a rise in blood sugar levels.
Insulin glargine is a slow acting form of insulin. Like other forms of insulin, insulin glargine is administered to keep the blood sugar levels as close to normal as possible. This long-acting insulin is injected under the skin and works slowly over a period of 24 hours to regulate the blood sugar level. Insulin glargine may be used in combination with other forms of insulin or with other diabetes medication to keep blood sugar levels properly regulated.
