Nearly half of all Americans take at least one prescription drug, with more than one in ten taking at least five prescriptions each month. For many who require prescriptions to manage chronic health conditions, finding ways to save money on these vital medications is necessary. Fortunately, there are many opportunities to save money on your prescriptions, including programs from retailers such as Costco.
Here is an overview of the Costco Member Prescription Program and pricing for the Costco Member Prescription Program preferred drug list.
What is the Costco Member Prescription Program?
All Costco members and their eligible dependents are welcome to join the Costco Member Prescription Program (CMPP), with no additional fee. If you’re a Costco member you simply need to present your Costco membership card at the pharmacy and ask to be enrolled in the CMPP.
The Costco Member Prescription Program will offer about 2% - 40% savings on prescription medications. The Costco Member Prescription Program also offers a preferred drug list, which represents medications with the most significant savings.
Authorized Generics Available Through the Costco Member Prescription Program
Authorized generics are identical to brand name drugs, and are available through the Costco Member Prescription Program. Authorized generics are available as an alternative to higher-priced brand name drugs. An authorized generic drug is made by the brand company, and is identical to the brand name product, whereas a generic drug has the same active ingredients, but may differ in terms of color, shape, size, or inactive ingredients.
What are the preferred drugs included in the Costco Member Prescription Program?
The Costco Member Prescription Program preferred drug list offers the most significant savings. The medications on the preferred drug list include both brand name drugs and generics. The pricing is subject to change without notice and may vary by Costco pharmacy location.
The preferred drug list provides an overview of types of medications available and offers some pricing on generics available through Costco Pharmacy.
Are there any restrictions on the Costco Member Prescription Program?
The only requirement to join the Costco Member Prescription Program is a Costco membership. Family members under the age of 18 and family pets are also eligible as dependents of the member. The CMPP is available at all Costco network pharmacies. To sign up for the CMPP, become a Costco member, and request your CMPP card from the Costco pharmacy.
Other Ways to Save on Prescription Costs
In addition to joining the Costco Member Prescription Program, there are many other ways to save money on prescription medications. Be sure to compare the CMPP pricing to other prescription drug coupon prices to ensure you save the most.
Prescription Prices May Vary at Different Pharmacies
Keep in mind that prescription prices are subject to change and subject to variation depending upon which pharmacy you use. It is smart to shop around to find the best pricing, as you may realize extra savings by filling your prescription at a pharmacy other than the one closest to you, or the one you most often use. RxSaver provides pricing for prescription medications at multiple pharmacies near you, when you search for the drug online, or in the RxSaver app.
Use RxSaver to Save Up to 85%
RxSaver can help you save on the cost of prescriptions, and in some cases can help you save more than Costco’s membership program. RxSaver provides prescription drug coupons for more than 6,000 different medications. Simply download the app, and search for your prescription drug, to find pricing for multiple pharmacies in seconds.
