Caterpillar Closed Formulary

Welcome to the Caterpillar Drug Formulary

This formulary applies to active Employees and certain Retirees that are covered by the prescription drug benefit provisions of the Caterpillar Inc. Employee Health, Life and Disability Benefit Program, the Caterpillar Inc. Retiree Benefit Program, the Caterpillar Inc. Group Insurance Plan A, and the Caterpillar Inc. Group Insurance Plan B.

What is a Formulary?

A formulary is a list of medications that are covered by the plan. The formulary is reviewed quarterly for possible additions and deletions. New generics for a covered brand name medication may be covered between quarterly updates based on plan approval and availability. Use of generic medication is required when generic is available.

The formulary is developed and maintained by a team of Physicians and Pharmacists based on product safety, efficacy, and clinical integrity. If a medication or product that has been prescribed for you or your covered dependents is not on the formulary, it is not a covered benefit. You will pay 100% of the full retail cost. You may wish to speak to your doctor for an alternative option.
