Costco Pharmacy Thanksgiving hours
Thanksgiving is the second-largest closure day. Most pharmacy counters are closed; some 24-hour drugstores keep front-store hours but the pharmacy itself is dark. All Costco warehouses and pharmacies are closed on Thanksgiving Day.
The Costco Pharmacy pharmacy counter typically follows a more conservative holiday schedule than the front store. Even when the front of the store is open, prescription fills require a licensed pharmacist on duty, and most chains pull pharmacist coverage on the highest-closure holidays. For a non-urgent refill, the practical guidance is to fill it the day before — most apps will let you submit a refill request for next-day pickup, which guarantees the prescription is ready when the pharmacy reopens.

The most reliable national fallbacks for a Thanksgiving prescription fill are 24-hour Walgreens and CVS pharmacies. They are concentrated in major metros — Las Vegas, Phoenix, Houston, Atlanta, Chicago, Los Angeles, Miami — and almost always staff a pharmacist on holidays.
- Walgreens 24-hour pharmacy locations — the largest national 24-hour pharmacy footprint
- CVS 24-hour pharmacy locations — strong coverage in California, Florida, Texas, Illinois
- Walmart Pharmacy — most Supercenters open on non-Christmas/non-Thanksgiving holidays

Prescription pickup tips for Thanksgiving
- Refill 48 hours ahead. Most Costco Pharmacy pharmacies process refill requests within a few hours during normal staffing, but holiday week always runs slow.
- Use the Costco Pharmacy app. The app shows real-time pharmacy hours per location and will warn you if your local store is closed for the holiday.
- Call before you drive. Even at 24-hour locations, the on-shift pharmacist may be limited to emergency fills only. A 30-second call confirms the counter is staffed.
- Use a different chain if needed. Costco Pharmacy can transfer your active prescription to a competitor pharmacy in minutes — the transferring pharmacy makes the call.
