Costco Pharmacy hours are not necessarily the same as the operating hours of the Costco warehouse around them. That distinction matters when you need to pick up a prescription, speak with the pharmacy, or plan a Saturday visit.
Current official Costco location information shows that pharmacy schedules can vary between warehouses. Several locations checked in September 2026 list pharmacy service from 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. Other warehouses stay open later. Some locations also warn of a possible 30-minute midday closure when only one pharmacist is on duty.
Quick Answer
Many Costco Pharmacy locations currently list hours of 9:00 a.m. to 7:00 p.m. Monday through Friday, 9:00 a.m. to 6:00 p.m. Saturday, and closed Sunday. However, this is not a guaranteed nationwide schedule.
Some Costco pharmacies have longer weekday and Saturday hours. Costco itself advises customers to check the Store Details for their selected warehouse because service-department hours can differ by location.
Costco Pharmacy Hours at a Glance
| Day | Common Schedule Found in Current Official Location Pages | Important Note |
|---|---|---|
| Monday | 9:00 a.m.–7:00 p.m. | Some locations stay open later |
| Tuesday | 9:00 a.m.–7:00 p.m. | Check your selected warehouse |
| Wednesday | 9:00 a.m.–7:00 p.m. | Check your selected warehouse |
| Thursday | 9:00 a.m.–7:00 p.m. | Check your selected warehouse |
| Friday | 9:00 a.m.–7:00 p.m. | Some locations stay open later |
| Saturday | 9:00 a.m.–6:00 p.m. | Some locations stay open later |
| Sunday | Closed at locations checked | Verify locally before visiting |
These times are a useful reference based on current official location information, but they should not be interpreted as a universal schedule for every Costco Pharmacy.
What Time Does Costco Pharmacy Open?
A number of current Costco warehouse pages list the pharmacy opening at 9:00 a.m. Monday through Saturday.
That opening time was displayed for pharmacies at official Costco locations checked in Texas, California, Tennessee, and Washington.
The important distinction is that the pharmacy is a warehouse service with its own schedule. The main Costco warehouse may open or close at a different time.
For that reason, seeing that the Costco warehouse itself is open does not automatically mean the pharmacy counter is open.
What Time Does Costco Pharmacy Close?
Closing time is where location differences become especially important.
Several official Costco locations checked in September 2026 list pharmacy closing time as:
- 7:00 p.m. Monday through Friday
- 6:00 p.m. Saturday
- Closed Sunday
However, other official locations list later closing times.
For example, the official Costco pages for Everett, Washington and Vista, California showed pharmacy service until 8:30 p.m. on weekdays and 7:00 p.m. on Saturday when checked.
Therefore, there is no single closing time that should be assumed for every Costco Pharmacy.
Costco Pharmacy Hours by Day
For locations following the frequently observed 9:00 a.m.–7:00 p.m. weekday schedule, the hours look like this:
| Day | Pharmacy Hours |
|---|---|
| Monday | 9:00 a.m.–7:00 p.m. |
| Tuesday | 9:00 a.m.–7:00 p.m. |
| Wednesday | 9:00 a.m.–7:00 p.m. |
| Thursday | 9:00 a.m.–7:00 p.m. |
| Friday | 9:00 a.m.–7:00 p.m. |
| Saturday | 9:00 a.m.–6:00 p.m. |
| Sunday | Closed |
This table represents a schedule found across multiple current Costco location pages, not a corporate guarantee for every pharmacy. Locations with extended pharmacy hours can follow a different timetable.
Do Costco Pharmacy Hours Vary by Location?
Yes. Costco specifically tells customers that warehouse hours can have slight variations and directs customers to individual warehouse information for service-department schedules such as pharmacy, gas station, and optical services.
A September 2026 check of official Costco warehouse pages also demonstrates that difference.
| Costco Location Checked | Monday–Friday | Saturday | Sunday |
|---|---|---|---|
| Liberty Hill, Texas | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| Pharr, Texas | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| Mt. Juliet, Tennessee | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| City of Industry, California | 9:00 a.m.–7:00 p.m. | 9:00 a.m.–6:00 p.m. | Closed |
| Everett, Washington | 9:00 a.m.–8:30 p.m. | 9:00 a.m.–7:00 p.m. | Closed |
| Vista, California | 9:00 a.m.–8:30 p.m. | 9:00 a.m.–7:00 p.m. | Closed |
This sample is useful for demonstrating genuine location variation. It should not be used to predict the schedule of an unverified Costco Pharmacy.
Is Costco Pharmacy Open on Saturday?
Yes, the Costco Pharmacy locations checked for this guide list Saturday pharmacy hours.
A frequently listed Saturday schedule is 9:00 a.m. to 6:00 p.m.
Some locations operate later. The official pages for the Everett, Washington and Vista, California warehouses, for example, listed pharmacy service from 9:00 a.m. to 7:00 p.m. on Saturday when checked.
If you are planning a late Saturday prescription pickup, verify the pharmacy department rather than relying on the main warehouse closing time.
Is Costco Pharmacy Open on Sunday?
The Costco pharmacies sampled from current official location pages were closed on Sunday.
This includes the locations checked in Texas, California, Tennessee, and Washington.
Because Costco publishes pharmacy schedules at the individual warehouse level, the safest approach is still to check the pharmacy section for your specific warehouse before making a Sunday trip rather than treating a sampled pattern as a nationwide guarantee.
Does Costco Pharmacy Close for Lunch?
A midday interruption is possible at some Costco pharmacies.
Current official Costco warehouse pages checked for this guide state 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.
That wording is important. It does not mean every Costco Pharmacy automatically closes for a full hour or that every location takes a break at exactly the same time.
Instead, a temporary 30-minute closure may occur within that period under the staffing condition stated by Costco.
If you need to visit around midday, particularly for something requiring pharmacist assistance, checking directly with the pharmacy can prevent an unnecessary wait.
Costco Pharmacy Hours vs. Warehouse Hours
Costco Pharmacy hours should not be confused with Costco warehouse shopping hours.
A warehouse may still be open after its pharmacy has closed. Likewise, Costco publishes separate schedules for services such as:
- Pharmacy
- Gas station
- Tire Service Center
- Optical Department
For example, a Costco warehouse may remain open until 8:30 p.m. while its pharmacy closes at 7:00 p.m.
Always look specifically under Pharmacy in the warehouse’s service details when planning prescription pickup or an in-person pharmacy visit.
Costco Pharmacy Holiday Hours
Costco advises customers to use individual warehouse information to view adjusted holiday hours and closures.
That is especially important for pharmacy visits because the pharmacy department has its own operating schedule. A warehouse’s general holiday information should not automatically be converted into pharmacy hours unless the service schedule is specifically shown.
Holiday schedules can also change, so a regular Monday or Saturday timetable should not be assumed to apply when the date falls on or around a major holiday.
For a time-sensitive prescription pickup, verify the pharmacy’s current schedule before leaving home.
Costco Mail Order Pharmacy Hours
Costco’s Mail Order Pharmacy operates differently from a local warehouse pharmacy.
Costco states that its online pharmacy system is available 24 hours a day, seven days a week for activities such as ordering eligible new prescriptions, requesting refills, and checking prescription status.
That does not mean a live Costco pharmacy agent is available 24/7.
Current official information lists Pharmacy Member Service agent hours as:
| Day | Agent Availability |
|---|---|
| Monday–Friday | 5:00 a.m.–7:00 p.m. Pacific Time |
| Saturday | 9:30 a.m.–2:00 p.m. Pacific Time |
| Sunday | Not listed as an agent-service day |
These are Mail Order Pharmacy support hours and should not be confused with the operating hours of the pharmacy counter inside a Costco warehouse.
Can You Refill a Costco Prescription After the Local Pharmacy Closes?
Costco’s online pharmacy services provide options that are not limited to the hours of a physical pharmacy counter.
Its official pharmacy information states that online pharmacy functionality is available 24/7 for prescription refills, new prescription ordering, and prescription-status checking.
Physical pickup, however, still depends on the operating hours of your selected Costco Pharmacy. Completing or managing part of the prescription process online does not mean the local pharmacy counter will remain open outside its listed schedule.
Prescription Pickup Hours
Prescription pickup at a warehouse pharmacy is tied to that pharmacy’s operating hours.
Costco’s online pharmacy also supports Pay Ahead pickup. Once an eligible prescription has been packaged for pickup, Costco says the customer can receive a notification with a QR code used at the pharmacy.
You still need to arrive while the pharmacy is operating.
Costco’s current online pharmacy help information also states that a Pay Ahead prescription not picked up within 10 days of being filled is returned to stock, with collected payment refunded to the card.
How to Check Costco Pharmacy Hours Near You
The most reliable method is Costco’s official warehouse finder.
Search for your preferred warehouse and open its Store Details or Warehouse Services information. Look specifically for the Pharmacy entry rather than relying on the general warehouse schedule.
You can also:
- Check your selected warehouse in the Costco app.
- Review the Pharmacy section of the official warehouse page.
- Call the pharmacy directly if timing is critical.
- Use Google Maps as a secondary reference, especially for navigation.
Direct confirmation is particularly useful before a holiday, during the midday period, or when you need to arrive close to closing time.
Using the Costco App to Check Hours
Costco identifies its app as another way to find warehouse locations and operating hours.
Select the relevant location and verify the information associated with that warehouse. When pharmacy timing is the reason for your trip, make sure you are checking the pharmacy service rather than only the warehouse’s general opening and closing times.
This distinction can prevent a situation where you arrive while Costco is open but find that the pharmacy has already closed.
Why Your Local Costco Pharmacy May Have Different Hours
Current official location pages show that pharmacy closing times are not identical across all warehouses.
Several locations in the sample used for this guide closed at 7:00 p.m. on weekdays, while pharmacies in Everett and Vista were listed until 8:30 p.m.
The practical takeaway is simple: published hours for one Costco should not automatically be applied to another Costco.
Use the schedule attached to the exact warehouse where you plan to fill or collect your prescription.
Sources & Verification
This guide was checked in September 2026 against Costco’s official customer-service information, Costco Pharmacy information, online pharmacy help resources, and individual official warehouse pages.
Location-level pharmacy schedules were compared across Costco warehouses in Texas, California, Tennessee, and Washington. The comparison confirmed that pharmacy closing times can differ by warehouse, while the sampled locations were all listed as closed on Sunday.
Because pharmacy and holiday schedules can change, the official Store Details for your selected Costco warehouse remain the most reliable source before a time-sensitive visit.
