Does Lantus Cause Cancer As A Side Effect
No, Lantus is not known to cause cancer. In clinical trials, the incidence of cancer was similar between treatment groups. And it hasnt been reported since this medication has been available for use.
Certain drugs for type 2 diabetes called thiazolidinediones have been linked to bladder cancer in some people. TZDs include rosiglitazone and pioglitazone . However, its not known for certain if these drugs increase the risk of bladder cancer.
Lantus is not related to these drugs. Lantus is a type of insulin. And no types of insulin are known to cause cancer.
If youre concerned about the risk of cancer with your diabetes medications, talk with your doctor.
Does Lantus Treat Diabetic Ketoacidosis
No. Lantus isnt used to treat diabetic ketoacidosis .
DKA is a serious complication of diabetes. It occurs when your blood sugar levels are very high but your insulin levels are low. Because insulin isnt available to move sugar into your cells, they cant use the sugar as fuel. Instead, your body starts breaking down fat into ketones for energy. High levels of ketones make your blood more acidic, which can harm many organs in your body.
DKA treatment takes place in a hospital setting. Treatment involves using insulin to bring sugar into your cells. However, Lantus isnt the best type of insulin for this process because it takes too long to start working. Faster-acting insulins such as insulin aspart , insulin glulisine , or insulin lispro are typically used as part of DKA treatment.

A Guide To Lantus Insulin Treating Diabetes
indications for Lantus Lantus is a brand of insulin used to treat diabetes mellitus. An insulin glargine — a type of insulin that is structurally identical to, but not, human produced insulin — Lantus is designed to be longer lasting than other insulins, lasting up to 24 hours . Like all other forms of insulin, Lantus is taken subcutaneously , and can be a critical part of treating your dog or cats diabetes. Precautions Injections should not be administered in the same spot every day, as this could cause scarring, which will dampen the bodies ability to absorb the medication. Use with anabolic steroids, adrenergic blockers, MAOIs, aspirin , phenylbutazone, or tetracycline might increase the effects of Lantus, and should be monitored, while DOBUTamine, EPINEPHrine, furosemide, thiazide, progesterone, glucocorticoids, and estrogen, may decrease the effects. Taking with burdock may have a hypoglycemic effect, and the dosage of insulin may need to be adjusted accordingly. Pets taking digoxin should have their potassium levels monitored. Dosage Typically eliciting a much stronger reaction from dogs than from cats, the dosage will typically start out much lower than with other types of insulin, roughly .1 unit/kg twice a day.Continue reading > >

Lantus For Type 1 Diabetes
Lantus is approved by the FDA to improve blood sugar levels in adults and children with type 1 diabetes.
Type 1 diabetes is a chronic condition where your pancreas doesnt make insulin. Your body needs the hormone insulin to bring sugar into your cells, where sugar is used for energy. Without insulin, your cells cant get the energy they need to work properly. It also leads to high blood sugar levels, which can cause serious problems if not treated.
People with type 1 diabetes need to take insulin to survive.
Note: Lantus isnt approved to treat DKA, which is a possible complication of diabetes. For more information about DKA, see the Common questions about Lantus section below.
