Is Costco Pharmacy open on Saturday?

Costco Pharmacy is open Saturday 9:30 AM to 6:00 PM, opening 30 minutes earlier than weekdays but closing an hour earlier. Most pharmacies still observe the 1:30 PM to 2:00 PM lunch break on Saturday, depending on staffing. Saturday is the busiest day for refill pickups in most warehouses since Sunday is closed. Drop off prescriptions before 5 PM Saturday so the pharmacist has time to fill before close. The drive-thru window is the fastest pickup option at warehouses that have one.

Is Costco Pharmacy open on Sunday?

Costco Pharmacy is closed all day Sunday at every location nationwide. The warehouse itself is open Sunday 10:00 AM to 6:00 PM for regular members, but the pharmacy counter is unstaffed.

Costco offers a workaround: the mail-order pharmacy at rx.costco.com runs 24/7 with free standard shipping for members and processes refill requests on Sundays. For urgent same-day needs, use a 24/7 chain like CVS or Walgreens, or a 7-day grocery pharmacy like Publix or H-E-B.
