Can you inject too much long-acting insulin?

Yes, injecting too much long-acting insulin can lead to hypoglycemia (low blood sugar), which is a serious concern. This is one of the main risks associated with insulin therapy.

Low blood sugar is more likely to happen in certain situations:
- You drink more alcohol than usual, especially liquor
- You exercise intensely
- You miss meals or eat later than usual

When experiencing hypoglycemia, you may feel dizzy, shaky, sweaty, or anxious. It's important to recognize these symptoms and treat low blood sugar promptly.

Your healthcare team will work closely with you to determine the right dosage and schedule for your long-acting insulin. They may ask you to track how your body responds to insulin, especially at the beginning of treatment. If you need more or less insulin than initially prescribed, they can adjust your doses accordingly.

If you're concerned about taking too much insulin or experiencing low blood sugar episodes, talk to your doctor right away. They can help you adjust your treatment plan and may suggest using a patch or insulin pump to better monitor your glucose levels and ensure you're getting the right amount of insulin when you need it.
