Costco Pharmacy Hours 2026: Full Schedule & Everything
Quick Answer: Costco Pharmacy hours typically run 10:00 AM to 7:00 PM on weekdays, with shorter weekend hours and you must be a Costco member to use them.
You’ve been filling your prescriptions at Costco for years because the prices are genuinely hard to beat and then one Saturday afternoon you show up and the pharmacy window is dark at 5:30 PM. It’s frustrating, especially when you assumed weekend hours matched the store. In 2026, Costco Pharmacy hours run on a tighter schedule than the warehouse itself, and the gap between when the store closes and when the pharmacy closes is bigger than most members realize.
Costco Pharmacy is one of the most cost-effective prescription options in the country, offering some of the lowest drug prices available to members without requiring insurance. But that value comes with a tighter operating window than CVS or Walgreens. This article covers the full weekly and weekend schedule, holiday closures, how to confirm your local location’s hours, and what to know before making the drive. Here’s the complete picture.
What Are Regular Costco Pharmacy Hours?
Costco Pharmacy typically operates from 10:00 AM to 7:00 PM on weekdays at most warehouse locations. This is a notably shorter window than most standalone pharmacies, reflecting Costco’s warehouse-style operating model. Hours may vary by location, with some busier warehouse pharmacies extending to 8:00 PM on weekdays in high-demand markets.
The pharmacy opens later and closes earlier than the warehouse itself a detail that surprises a lot of members on their first pharmacy visit. The good news is that the prices and service quality inside that window make it worthwhile. Just don’t plan an after-8:00 PM prescription pickup at Costco the way you might at a Walgreens.
| Day | Pharmacy Hours |
|---|---|
| Monday | 10:00 AM – 7:00 PM |
| Tuesday | 10:00 AM – 7:00 PM |
| Wednesday | 10:00 AM – 7:00 PM |
| Thursday | 10:00 AM – 7:00 PM |
| Friday | 10:00 AM – 7:00 PM |
| Saturday | 9:30 AM – 6:00 PM |
| Sunday | 10:00 AM – 5:00 PM |
Pharmacy vs. Store Hours at Costco: Key Difference
Costco warehouse stores typically open at 10:00 AM and close between 8:30 PM and 9:30 PM — significantly later than the pharmacy. The pharmacy counter closes hours before the store, which means you can shop for groceries and bulk goods well after the pharmacy has shut down. Hours may vary by location, but the pharmacy always closes before the warehouse does.
A practical tip: if you’re planning a pharmacy pickup on a weekday evening, aim to arrive before 6:30 PM. That gives you buffer time if there’s a wait, an insurance issue, or your prescription isn’t quite ready. Cutting it close to the 7:00 PM close at Costco rarely ends well.
Weekend Costco Pharmacy Hours: Saturday and Sunday
Weekend Costco Pharmacy hours are notably shorter than weekdays. Saturday service runs approximately 9:30 AM to 6:00 PM at most locations, while Sunday hours compress to 10:00 AM to 5:00 PM — making it the tightest window of the entire week. Hours may vary by location, so a high-volume urban Costco may push Sunday to 6:00 PM, while quieter locations may close even earlier.
Sunday afternoon prescription pickups at Costco require real planning. If you need a Sunday fill, get there before 4:30 PM to give yourself a reasonable buffer. The pharmacy starts winding down well before the official closing time, and complex prescriptions or insurance questions become much harder to resolve in the final 30 minutes.
Costco Pharmacy Holiday Hours: What Closes and When
Costco Pharmacy closes on more holidays than most chain pharmacies. As a warehouse-model retailer, Costco tends to close the entire building including the pharmacy on several major holidays each year. Individual locations set their own schedules, but corporate-directed closures are more common here than at standalone pharmacy chains. Always call ahead before a holiday visit.
| Holiday | Status | Typical Hours |
|---|---|---|
| New Year’s Day | Usually Closed | Closed |
| Easter | Usually Closed | Closed |
| Memorial Day | Usually Open | 10:00 AM – 5:00 PM |
| Fourth of July | Usually Open | 10:00 AM – 5:00 PM |
| Labor Day | Usually Open | 10:00 AM – 5:00 PM |
| Thanksgiving | Closed | Closed |
| Christmas Day | Closed | Closed |
| Christmas Eve | Reduced Hours | 10:00 AM – 4:00 PM |
How to Find Costco Pharmacy Hours Near You
Before making the drive, always verify your specific warehouse’s pharmacy schedule. Here are four reliable methods:
- Google Search — Type “Costco Pharmacy hours near me” for quick results showing your nearest location and its current pharmacy schedule
- Google Maps — Search your specific Costco address and look for pharmacy hours listed separately, or check the customer Q&A section for recent member-confirmed details
- Official Website — Visit costco.com and use the warehouse locator to find your location — pharmacy hours are listed on each individual warehouse page under the services section
- Direct Phone Call — Call the warehouse directly and ask to be connected to the pharmacy; staff can confirm current hours, prescription status, and any same-day schedule changes
The phone call is especially critical before holiday visits. Costco’s holiday closure list is longer than most members expect, and finding a closed pharmacy after a long drive is genuinely frustrating when a quick call would have prevented it entirely.
Costco Drive-Thru and Curbside Pharmacy Hours
Costco Pharmacy does not offer a traditional drive-thru window at most locations. Unlike CVS or Walgreens, where drive-thru lanes are a standard feature, Costco’s pharmacy model is built around walk-in warehouse access. Hours may vary by location, and a small number of newer warehouse formats may include pickup options, but these are not widespread across the chain.
Curbside pharmacy pickup is similarly limited at Costco. The warehouse model isn’t designed for individual item curbside service the way a retail pharmacy is. If drive-thru or curbside access is important to you for mobility or convenience reasons, a standalone pharmacy chain may better suit your needs for that specific pickup.
24-Hour Costco Pharmacy Services and Availability
Costco does not operate any 24-hour pharmacy locations. The warehouse model depends entirely on in-store staffing and member foot traffic during defined operating hours overnight pharmacy service doesn’t fit that structure. Hours may vary by location, but no Costco warehouse anywhere in the United States offers around-the-clock pharmacy access.
If you need a prescription filled outside of Costco Pharmacy hours, you’ll need to use a 24-hour Walgreens or CVS location instead. Knowing your nearest 24-hour pharmacy option in advance is a smart habit particularly for anyone managing chronic medications that can’t wait until the next morning.
Prescription Pickup Times and Cut-Off Hours at Costco Pharmacy
New prescriptions submitted within 1 to 2 hours of Costco Pharmacy closing may not be ready same day. The pharmacy staff needs adequate processing time particularly for new scripts requiring insurance authorization or pharmacist review. Hours may vary by location in terms of how early that informal cutoff takes effect, but arriving with a new prescription at 6:30 PM on a weekday is always a risk.
A few habits that make Costco pharmacy visits consistently smoother:
- Call or submit prescriptions by 5:00 PM on weekdays to guarantee same-day filling
- Use the Costco pharmacy app or website to check prescription status before making the drive
- Bring your membership card every time — pharmacy access requires active Costco membership
- Transfer existing prescriptions in advance — don’t wait until you’ve run out to initiate a transfer to Costco from another pharmacy
Factors Affecting Costco Pharmacy Hours
Several factors can cause your local Costco Pharmacy to operate on a different schedule than the posted standard:
- Warehouse size and membership volume — Larger, busier warehouses tend to maintain longer pharmacy hours to serve higher member demand
- Pharmacist staffing — Short staffing can lead to reduced hours or temporary service interruptions
- State regulations — Some states have specific requirements around pharmacy operating hours and minimum staffing ratios
- Local market conditions — Costco pharmacies in markets with strong competition may extend hours to retain member prescription business
- Seasonal demand — Flu season and back-to-school periods can influence adjusted hours at some locations
Seasonal and Temporary Changes in Costco Pharmacy Hours
Costco Pharmacy hours can shift during peak flu vaccination season, which typically runs September through November. Some locations extend weekday hours by 30 to 60 minutes during this period to accommodate increased vaccine appointment demand. Hours may vary by location and year, so checking current hours in real time during flu season is especially worthwhile.
Temporary closures can also happen with little warning during severe weather events or local emergencies. Unlike standalone pharmacies that sometimes stay open even in difficult conditions, Costco’s warehouse model means the entire building typically closes when conditions deteriorate. During major weather events, always call ahead before assuming the pharmacy is operating normally.
Contacting Costco Pharmacy for Current Hours
Calling your specific Costco warehouse pharmacy directly is the most reliable way to confirm current hours. The general Costco member services number is 1-800-774-2678, but speaking directly with the pharmacy staff at your local warehouse gets you the fastest, most accurate answers. Hours may vary by location in ways that national customer service lines simply can’t account for.
The Costco website is also worth bookmarking for regular pharmacy users. The warehouse locator at costco.com lists pharmacy hours for each location individually, and those hours are generally updated more reliably than third-party sites. Combining the website check with a quick phone call gives you complete confidence before making the trip.
