Key takeaways
Humalog (insulin lispro) and Actos (pioglitazone) are both used to manage diabetes, but they work in different ways and are used for different types of diabetes. Humalog is a rapid-acting insulin that you inject to control blood sugar levels in people with type 1 and type 2 diabetes. It starts working within 15 minutes and lasts for 2 to 4 hours and taken multiple times a day with meals. On the other hand, Actos is a thiazolidinedione taken as a pill once daily with or without food, to help your body use insulin better only for patients with type 2 diabetes. Actos can take several weeks to show its full effect. Humalog can cause low blood sugar and weight gain, while Actos can cause fluid buildup, weight gain, and has a risk of bladder cancer and heart failure. Actos is not recommended for people with type 1 diabetes or those with bladder cancer.
