The 90th Medical Group Pharmacy at FE Warren AFB follows the TRICARE Uniform Formulary. Please note that not all formulary medications will be routinely stocked at the pharmacy and may need to be ordered in. If a medication requires a Prior Authorization, it will need to be submitted to Express Scripts by your provider. Patients and Providers, please see the section, Related Pharmacy Links, for more information.

Pharmacy Prescription Activation

To increase patient safety and reduce pharmacy waste, you must first activate your prescriptions at the pharmacy. To activate a prescription, call 307-773-3638, or activate online by sending the pharmacy a message through the MHS GENESIS Patient Portal. Prescriptions cannot currently be activated at the pharmacy window.

Auto-Notify Service

Let a pharmacy staff member know if you would like to receive a call or text when your prescription is ready. Prescriptions are often ready sooner than the promised pick-up time, and a phone message can let you know as soon as they are done.

Electronic Prescriptions

Sending prescriptions electronically is the safest and most preferred method for all prescriptions to include controlled substances. Have your doctor send all your prescriptions electronically to “DOD FE WARREN AFB EPHARM.” After your doctor sends us a prescription, please call 307-773-3638 to activate the medication for us to start filling it.

Hard Copy Prescriptions

Electronic prescriptions are safer, faster, and more convenient than “hard-copy” paper prescriptions and are preferred in the pharmacy. If your provider gives you a paper prescription, please ask them if they can send it electronically instead. If your provider is unable to send your prescriptions electronically, hard-copy prescriptions will still be accepted.


Patients may request refills 24-hours a day on the automated refill line at 307-773-2330 or by sending the pharmacy a message through the MHS GENESIS Patient Portal. Refills for most medications may be requested when 75% of your current medication has been used. That means you may request a refill up to 3-weeks early on a 90-day supply of medication.

Controlled substances can only be refilled three days early. If you have no remaining refills, you will need to contact your provider to send us a new prescription. Please do this at least a week before you run out of medication.

Prescription Pick-Up

Once your prescription is ready, please proceed to the pharmacy windows inside the building.  Be advised, masks are mandatory while in the Medical Group.

Processing Time

Once activated, new prescriptions are ready within 24 hours. Some medications may be ready same day after consultation with pharmacy staff. All prescription refills will be ready within three duty days. Certain medications may need to be ordered in, which will add to processing time. Be sure to sign up for auto-notifications so you can know exactly when your prescription is ready (often sooner than the promised pick-up time).
