Lantus insulin glargine prescribing information hypoglycemia
Yes. Lantus (insulin glargine) can cause hypoglycemia, or low blood sugar. It is a long-acting insulin, so low glucose can occur hours after the injection and may last longer than with shorter-acting insulin.
Risk is higher if you:
- Take more insulin than needed or accidentally double-dose
- Eat less than usual, skip meals, vomit, or fast
- Exercise more than usual
- Drink alcohol, especially without eating
- Have declining kidney or liver function
- Use other glucose-lowering medicines
Common symptoms include shakiness, sweating, hunger, fast heartbeat, headache, dizziness, irritability, confusion, blurred vision, or weakness. The FDA labeling identifies hypoglycemia as the most common adverse effect of insulin, including Lantus. FDA prescribing information
If you are awake and able to swallow: take 15-20 g of fast carbohydrate, such as glucose tablets, 4 oz (120 mL) juice, or regular soda; recheck in 15 minutes and repeat if still low. Then eat a snack or meal if your next meal is not soon.
Get emergency help now for seizure, fainting, inability to swallow, severe confusion, or if glucagon is needed. Do not give food or drink to someone unconscious.
Do not stop or change Lantus doses without contacting your prescriber, but recurrent lows need a prompt dose and regimen review.
