State rules
Find out who fills the prescription
Ask for the pharmacy’s name early. Then check the pharmacy itself, even if you already checked the person treating you.
State rules and a way to ask for help
As of September 30, 2026, a pharmacy mailing prescription medicine into Washington usually needs a state license for an out-of-state pharmacy.
The law calls this a nonresident pharmacy license.
The state can make an exception for a pharmacy that only sends a rare order into Washington.
There must be a way to speak with a pharmacist
Under the same law as of September 30, 2026, that pharmacy must offer a free phone service during its regular hours.
The pharmacist must be able to see the patient’s records, and the phone number belongs on the medicine label.
How medicine is made and what goes in it
As of September 30, 2026, a pharmacy licensed in Washington must follow USP quality rules when making medicine to order.
USP stands for United States Pharmacopeia, the organization that sets these quality standards.
Research ingredients are not patient ingredients
In its July 31, 2026 bulletin, Washington’s Pharmacy Commission says patient medicines cannot contain ingredients marked for research or not for human use.
This bulletin explains the Pharmacy Commission’s position. It does not give permission to use any particular peptide in a made-to-order medicine. The pharmacy must check both Washington and federal ingredient rules.
