My insulin is four years old; is it okay still to use? I can't afford to buy more. I have type two diabetes and my sugars are everywhere.
Insulin is only good until the expiration date printed on the bottle and on the outside of the box. Once it is beyond that expiration date, the strength and effectiveness of that insulin cannot be guaranteed. Insulin that is four years old is well beyond its expiration date and needs to be thrown away. Talk with your healthcare provider about ways to get less expensive insulin. If you have no insurance, the insulin companies will send you free insulin, provided your income is low enough and the proper paperwork is filled out by you and your healthcare provider. If you do not have a primary care provider, check in your area to see if there are any free clinics or community health centers that might be able to help you. Often times at free clinics and community health centers, free samples of medicine are available for people in your situation. If your income is low enough, you may also qualify for Medicaid. Call your state Department of Welfare and talk to one of the social workers; they should be able to help you fill out the paperwork if you qualify for assistance.
