Why does Diltiazem Hcl Er (Cardizem) cost more in one country than the other?
Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.
What should I expect to pay for Cardizem LA with insurance?
Your copay for Cardizem LA with insurance depends on your specific plan's formulary and benefit structure. It is recommended to ask your pharmacist to check the price using your insurance. You should also compare this cost with prices available through pharmacy savings programs, as these options can sometimes offer a lower price than a standard insurance copay.
Is Cardizem LA covered by Medicare, and what are the costs?
Most Medicare Part D prescription drug plans typically do not cover brand-name Cardizem LA, but they generally do cover generic extended-release diltiazem. If your plan does not cover Cardizem LA and a generic equivalent is not suitable for your treatment, you may face higher out-of-pocket costs. In such cases, exploring pharmacy discount programs can help provide savings at many pharmacies.
Are generic versions of Cardizem LA available?
Yes, the active ingredient in Cardizem LA, diltiazem, is available in several generic extended-release formulations from various pharmaceutical companies. Additionally, other branded formulations of extended-release diltiazem, such as Cartia XT, Matzim LA, Diltzac, and Taztia XT, are available and may have different insurance coverage.
