Attention TRICARE beneficiaries!  
You may experience busy signals when calling the military pharmacy prescription refill interactive voice response system – or prescription refill line – Jan. 26 to Feb. 5, 2026, as the system is updated.  
Each military pharmacy’s prescription refill line may be unavailable for about two hours. If you call the prescription refill line at this time, you will hear a busy signal. Please wait and call back to complete your refill later.
