Examples include human soluble insulin (Actrapid®, Humulin® S and Insuman Rapid®).

Intermediate-acting insulin

Usually taken once or twice a day. Starts working within 2 hours and lasts 8–14 hours.

Examples include isophane insulin (Insuman® Basal, Insulatard® and Humulin® I)

Long-acting insulin

Usually taken once or twice a day. Starts working within 2 hours and lasts up to 18–24 hours.

Examples include insulin detemir (Levemir®), insulin glargine (Abasaglar®, Lantus®, Toujeo®) and insulin degludec (Tresiba®).

Mixed Insulin

These insulins are a mixture of shorter-acting and longer-acting insulins and come in different preparations. Usually taken twice or three times daily, between 15–30 minutes before or just after food. Starts working within 30 minutes (depending on short-acting insulin).

Examples include biphasic insulin aspart (Novomix® 30), biphasic insulin lispro (Humalog® Mix 25, Humalog® Mix 50), soluble and isophane insulin (Humulin® M3, Insuman® Comb 15, Insuman® Comb 25, Insuman® Comb 50).
