Before you assume your copay changes this week, three caveats matter.
First, employers have the final say. CVS Caremark's template formulary is the default, but individual employers can customize their plan and some exclude weight loss medications entirely. Zepbound being "preferred" on the template does not guarantee your specific plan adopted it, so the only way to know is to check your plan documents on caremark.com or call the member services number on your card.
Second, prior authorization has not gone away. Both Zepbound and Wegovy still typically require your provider to document that you meet clinical criteria — generally a BMI of 30 or higher, or 27 or higher with a weight-related condition. If you were switched from Zepbound to Wegovy last year, be aware that your old Zepbound authorization was not held in reserve; switching back will usually mean a fresh prior authorization request from your provider.
Third, a formulary position is not a price. Preferred status usually means a lower copay tier, but what you actually pay depends on your plan design and deductible. Medicare patients are on a separate track entirely — if that is you, our guide to the Medicare $50 GLP-1 bridge program explains the current rules.
