COST: It will make a difference if you are on Medicare Part D. If so, in 2025 your maximum out of pocket will be $2000, assuming that your plan covers the drug. This is due to the new law put signed by our current President. See photo, from Medicare.gov. Please note the first sentence "PRESCRIPTION DRUGS COVERED BY YOUR PLAN"! If you are on Medicare Part D and your plan does not cover the drug, you need to switch plans NOW!
