Costco Pharmacy Hours 2026: Opening, Closing & Sunday Hours
Costco Pharmacy hours are not identical at every warehouse, so the pharmacy schedule should be checked separately from the main Costco warehouse hours. Current official Costco location pages show pharmacies commonly opening at 9:00 a.m., but closing times differ by warehouse. Many U.S. pharmacies are also closed on Sundays.
Another important detail is the pharmacist meal period. Costco states on many official warehouse pages that when only one pharmacist is on duty, the pharmacy may close for 30 minutes between 1:30 p.m. and 2:30 p.m.
Quick Answer
Current Costco warehouse pages checked in September 2026 show many U.S. Costco Pharmacies operating 9:00 a.m. to 7:00 p.m. Monday through Friday and 9:00 a.m. to 6:00 p.m. Saturday, with Sunday closed. However, this is not a universal national schedule. Some locations remain open later, including pharmacies with weekday hours until 8:30 p.m. and Saturday hours until 7:00 p.m.
Check the Pharmacy section on your selected Costco warehouse page before visiting.

What Time Does Costco Pharmacy Open?
In the U.S. locations reviewed for this guide, Costco Pharmacy opens at 9:00 a.m. Monday through Saturday.
For example, Costco’s official pages currently list a 9:00 a.m. pharmacy opening time at warehouses in Pensacola, Florida; King of Prussia, Pennsylvania; Northwest San Antonio, Texas; Mount Prospect, Illinois; Westbury, New York; Poway, California; Gig Harbor, Washington; and Billings, Montana.
That does not establish a guaranteed 9:00 a.m. opening time at every Costco Pharmacy. Costco recommends checking the individual warehouse’s Store Details for service-specific hours.
What Time Does Costco Pharmacy Close?
Costco Pharmacy closing times vary by warehouse.
Several official Costco locations checked in September 2026 list a 7:00 p.m. weekday closing time, including:
- Pensacola, Florida
- King of Prussia, Pennsylvania
- Northwest San Antonio, Texas
- Mount Prospect, Illinois
- Westbury, New York
- East Jacksonville, Florida
Other locations stay open later. The official pages for Billings, Montana; Poway, California; and Gig Harbor, Washington list pharmacy hours until 8:30 p.m. Monday through Friday.
Saturday closing times also differ. Many sampled locations close at 6:00 p.m., while others list a 7:00 p.m. Saturday closing time.
The practical takeaway is that Costco warehouse closing time should not be used as a substitute for pharmacy closing time.
Costco Pharmacy Hours by Day
Costco does not publish one universal Monday-through-Sunday pharmacy schedule that can safely be applied to every U.S. warehouse.
Based on the geographically varied official locations checked for this guide, the following patterns appeared:
| Day | Hours Seen at Sampled Locations | Important Note |
|---|---|---|
| Monday | 9:00 a.m.–7:00 p.m. or 8:30 p.m. | Location-specific |

This table summarizes only the official locations researched for this article. It should not be interpreted as a nationwide Costco Pharmacy timetable.
Costco Pharmacy Hours Compared Across Locations
Official Costco pages demonstrate why checking the individual pharmacy matters. The following locations were reviewed on September 25, 2026:
| Costco Location | Monday–Friday | Saturday | Sunday |
|---|---|---|---|
| Pensacola, Florida | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| King of Prussia, Pennsylvania | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| Northwest San Antonio, Texas | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| Mount Prospect, Illinois | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| Westbury, New York | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–7:00 p.m. | Closed |
| Billings, Montana | 9:00 a.m.–8:30 p.m. | 9:00 a.m.–7:00 p.m. | Closed |
| Poway, California | 9:00 a.m.–8:30 p.m. | 9:00 a.m.–7:00 p.m. | Closed |
| Gig Harbor, Washington | 9:00 a.m.–8:30 p.m. | 9:00 a.m.–7:00 p.m. | Closed |
The sample covers warehouses in the Northeast, South, Midwest, Mountain West, West Coast, and Pacific Northwest. It confirms meaningful differences in closing times even though the sampled pharmacies share a 9:00 a.m. opening time.
Is Costco Pharmacy Open on Sunday?
The U.S. Costco Pharmacies sampled for this guide are closed on Sunday.
That includes the official warehouse pages checked in Florida, Pennsylvania, Texas, Illinois, New York, Montana, California, and Washington.
However, Costco operates in multiple countries, and pharmacy schedules outside the United States can differ. For example, Costco’s official Ajax, Ontario warehouse page currently lists Sunday pharmacy hours. For that reason, Sunday closure should not be presented as a worldwide Costco Pharmacy policy.
Always check your specific warehouse when Sunday availability matters.
Does Costco Pharmacy Close for Lunch?
A Costco Pharmacy can temporarily close during the afternoon when staffing requires it.
Multiple current official Costco warehouse pages state that when only one pharmacist is on duty, the pharmacy may be closed for 30 minutes between 1:30 p.m. and 2:30 p.m.
This does not mean every pharmacy automatically closes for the entire 1:30–2:30 p.m. period. The wording is conditional and specifies a 30-minute closure when only one pharmacist is working.
If you plan to arrive during that window, checking with the pharmacy directly can help avoid a temporary closure.
Are Costco Pharmacy Hours the Same as Warehouse Hours?
No. Pharmacy hours can differ from the general Costco warehouse schedule.
For example, some warehouses remain open after their pharmacies have closed. Costco’s official location pages list Pharmacy as a separate warehouse service and provide department-specific hours where applicable.
This distinction is especially important when planning to:
- Pick up a prescription
- Speak with pharmacy staff
- Transfer a prescription
- Ask about a prescription’s status
- Visit near the end of the day
Check the Pharmacy listing rather than relying only on the main warehouse opening and closing times.
Costco Pharmacy Holiday Hours
Holiday pharmacy hours should be verified for the specific Costco warehouse rather than inferred from ordinary weekday or Saturday schedules.
Costco’s customer-service guidance says its Find a Warehouse feature displays adjusted holiday hours and closures. Because holiday schedules can change and pharmacy hours are service-specific, a warehouse’s normal schedule does not establish that its pharmacy will operate the same hours on a holiday.
Before making a holiday pharmacy trip, check the selected warehouse’s current information and contact the pharmacy directly when necessary.
Costco Mail Order Pharmacy Hours
Costco’s Mail Order Pharmacy operates differently from an in-warehouse pharmacy.
Costco currently states that its online pharmacy system is available 24 hours a day, seven days a week for functions including refilling prescriptions, ordering new prescriptions, and checking prescription status.
For assistance from a Costco pharmacy agent, Costco lists these current service hours:
| Day | Costco Pharmacy Agent Hours |
|---|---|
| Monday–Friday | 5:00 a.m.–7:00 p.m. PT |
| Saturday | 9:30 a.m.–2:00 p.m. PT |
| Sunday | No agent hours listed |
The Costco Mail Order Pharmacy customer-service number is 1-800-607-6861.
Online availability should not be confused with the operating hours of a physical Costco warehouse pharmacy.
How to Check Costco Pharmacy Hours Near You
The most reliable method is Costco’s official warehouse locator. Search by city, state, or ZIP code, choose your warehouse, and look under its services for Pharmacy.
Use this order when verifying your hours:
- Check Costco’s official Find a Warehouse tool.
- Open your specific warehouse page and find the Pharmacy section.
- Check the Costco app for current location information.
- Call the pharmacy using the phone number shown on the official warehouse page if your timing is critical.
- Use Google Maps as a secondary reference rather than the final source for pharmacy-specific hours.
Costco’s own customer-service guidance says there may be slight variations in warehouse hours and recommends checking the desired warehouse. It also directs customers to Store Details for service hours such as the pharmacy.
Check Costco Pharmacy Hours in the Costco App
Costco identifies its app as another way to find location hours.
After selecting the relevant warehouse, confirm that you are looking at the pharmacy information rather than only the general warehouse schedule. This distinction matters because the warehouse, pharmacy, gas station, tire center, and other services may follow different schedules.
For prescription-specific questions that cannot be answered from the listed hours, contact the selected pharmacy directly.
