Why might my copay/coinsurance for NEXIUM have changed?
The amount of your copay or coinsurance is determined by your plan and what formulary tier or level NEXIUM is on within that plan. Typically, a lower tier will have a lower cost, while a higher tier will have a higher cost. Your plan administrator will be able to give you detailed information about your prescription medication costs and the reasons for any changes to your out-of-pocket costs. If you get your prescription drug coverage through your employer, your human resources or benefits manager may also be able to answer questions about your plan.
