Costco Pharmacy Fontana hours
Costco Pharmacy runs Fontana-area locations on the chain-wide schedule above. As with every major metro, exact hours vary store by store — central-city locations near hospitals and university medical centers often open earlier and close later, while suburban Supercenter-anchored locations follow the more conservative schedule. Use the Costco Pharmacy app or the corporate store locator to confirm the hours of a specific Fontana store.
24-hour Costco Pharmacy in Fontana
Costco does not operate any 24-hour locations. Pharmacy counters close earlier than the warehouse and are dark all day Sunday at most clubs. For Fontana specifically, the strongest signal that an overnight pharmacist is on duty is the "Pharmacy: Open 24 hours" line on the location page in the Costco Pharmacy app — never assume a 24-hour storefront includes a 24-hour pharmacy counter without checking that line.
Costco Pharmacy Fontana holiday hours
Holiday hours at the Fontana Costco Pharmacy stores follow the chain's national holiday calendar. Costco Pharmacy keeps holiday schedules consistent between markets, so the table above applies to every Fontana location — though as always, the pharmacy counter may open later or close earlier than the front store.
