How insulin glargine recombinant is dosed
From the FDA label for Lantus (application BLA021081). Other insulin glargine recombinant products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
Individualize dosage based on metabolic needs, blood glucose monitoring, glycemic control, type of diabetes, and prior insulin use. ( 2.1 , 2.2 , 2.3 , 2.4 ) Administer subcutaneously into the abdominal area, thigh, or deltoid once daily at any time of day, but at the same time every day. ( 2.1 ) Do not dilute or mix with any other insulin or solution. ( 2.1 ) Rotate injection sites to reduce risk of lipodystrophy and localized cutaneous amyloidosis. ( 2.1 ) See Full Prescribing Information for the recommended starting dosage in patients with type 2 diabetes and how to change to LANTUS from other insulins ( 2.3 , 2.4 ) Closely monitor glucose when switching to LANTUS and during initial weeks thereafter. ( 2.4 ) 2.1 Important Administration Instructions Always check insulin labels before administration [see Warnings and Precautions (5.4) ] Visually inspect LANTUS vials and SoloStar prefilled pens for particulate matter and discoloration prior to administration. Only use if the solution is clear and colorless with no visible particles. Administer LANTUS subcutaneously into the abdominal area, thigh, or deltoid, and rotate injection sites within the same region from one injection to the next to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis [see Warnings and Precautions (5.2) and…
Insulin Glargine Recombinant side effects
The following adverse reactions are discussed elsewhere: Hypoglycemia [see Warnings and Precautions (5.3) ] Hypoglycemia Due to Medication Errors [see Warnings and Precautions (5.4) ] Hypersensitivity Reactions [see Warnings and Precautions (5.5) ] Hypokalemia [see Warnings and Precautions (5.6) ] Adverse reactions commonly associated with LANTUS include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, pruritus, rash, edema, and weight gain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact sanofi-aventis at 1-800-633-1610 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in practice. The data in Table 1 reflect the exposure of 2,327 patients with type 1 diabetes to LANTUS or NPH in Studies A, B, C, and D [see Clinical Studies (14.2) ] . The type 1 diabetes population had the following characteristics: Mean age was 39 years. Fifty-four percent were male, 97% were Caucasian, 22% were Black or African American and 33% were Hispanic. The mean BMI was 25.1 kg/m 2 . The data in Table 2 reflect the exposure of 1,563 patients with type 2 diabetes to LANTUS or NPH in Studies E, F,…
Who shouldn’t take insulin glargine recombinant
LANTUS is contraindicated: During episodes of hypoglycemia [see Warnings and Precautions (5.3) ] In patients with hypersensitivity to insulin glargine or any of the excipients in LANTUS [see Warnings and Precautions (5.5) ] During episodes of hypoglycemia ( 4 ) Hypersensitivity to insulin glargine or any of the excipients in LANTUS ( 4 )
Insulin Glargine Recombinant drug interactions
Table 8 includes clinically significant drug interactions with LANTUS. Table 8: Clinically Significant Drug Interactions with LANTUS Drugs that May Increase the Risk of Hypoglycemia Drugs : Antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, salicylates, somatostatin analogs (e.g., octreotide), sulfonamide antibiotics. GLP-1 receptor agonists, DPP-4 inhibitors, and SGLT-2 inhibitors. Intervention : Dosage reductions and increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs. Drugs that May Decrease the Blood Glucose Lowering Effect of LANTUS Drugs : Atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline), and thyroid hormones. Intervention : Dosage increases and increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs. Drugs that May Increase or Decrease the Blood Glucose Lowering Effect of LANTUS Drugs : Alcohol, beta-blockers, clonidine, and lithium salts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Intervention : Dosage adjustment and increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs. Drugs that May Blunt Signs and Symptoms of Hypoglycemia Drugs : Beta-blockers, clonidine, guanethidine, and reserpine. Intervention : Increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs. Drugs that Affect Glucose Metabolism : Adjustment of insulin dosage may be needed. ( 7 ) Antiadrenergic Drugs ( e.g., beta-blockers, clonidine, guanethidine, and reserpine ): Signs and symptoms of hypoglycemia may be reduced or absent. ( 5.3 , 7 )

What people report to the FDA about insulin glargine recombinant
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 63 reports naming insulin glargine recombinant, and the FDA flagged 97% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- hyperglycaemia7 reports
- urinary tract infection7 reports
- diabetes mellitus inadequate control5 reports
- hypertension5 reports
- renal impairment5 reports
- altered state of consciousness4 reports
- diabetic ketoacidosis4 reports
- hypoglycaemia4 reports
Read these as a signal, not a rate. A report does not mean insulin glargine recombinant caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
What is insulin glargine recombinant?
Lantus (Insulin Glargine Recombinant) is a medication supplied as an injection, solution.
Can you take insulin glargine recombinant with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run insulin glargine recombinant against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What brand names is insulin glargine recombinant sold under?
We track 4 insulin glargine recombinant-containing products in the U.S.: Lantus, Lantus Solostar, Toujeo Max Solostar and Toujeo Solostar. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does insulin glargine recombinant come in?
Across the brands we track, insulin glargine recombinant is currently marketed as injectable, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic insulin glargine recombinant?
We do not currently list a generic-labelled insulin glargine recombinant product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
