There are several types of insulin used to treat type 1 diabetes. They can be categorized based on their onset of action, peak time, and duration of action. The main types of insulin include:
- Rapid-acting insulin: This type of insulin starts working quickly, usually within 15 minutes after injection. It reaches its peak effect in about 1 to 2 hours and lasts for about 3 to 4 hours. Examples include insulin lispro, insulin aspart, and insulin glulisine.
- Short-acting insulin: Also known as regular insulin, it takes effect within 30 minutes after injection. It peaks in about 2 to 4 hours and lasts for about 6 to 8 hours.
- Intermediate-acting insulin: This type of insulin starts working within 1 to 2 hours after injection, peaks in about 4 to 6 hours, and can last for about 12 to 18 hours. Examples include NPH insulin.
- Long-acting insulin: This type of insulin has a slow and consistent effect over an extended period. It starts working within 1 to 2 hours, has no noticeable peak, and can last for about 24 hours or longer. Examples include insulin glargine and insulin detemir.
- Pre-mixed insulin: This type of insulin is a combination of different types of insulin. It typically contains a mixture of rapid or short-acting insulin and intermediate-acting insulin, providing both short-term and long-term blood sugar control.
It’s important to note that the specific insulin regimen and types used may vary depending on individual needs and recommendations from healthcare professionals.
