Most pharmacies are closed on Christmas Day, but there may be some that are open on a limited basis. You can check with your local pharmacies to see if any of them are open, or you can search for "pharmacy open near me" to find a list of pharmacies that may be open. Some pharmacies may have extended hours on Christmas Eve, and may also have after-hours emergency services available. It is best to plan ahead and make sure you have enough medication to last through the holiday period, as it can be difficult to get medical assistance during this time.
