Fourteen sites across the region will be available on Sunday 17 April, with more locations also staying open on both Friday 15 and Monday 18 April.
As the weekend is bookended by the Good Friday and Easter Monday bank holidays, most pharmacies will close at the end of the day on Thursday 14 April, and not reopen until Tuesday 19 April.
Ahead of the break, people taking regular medication are being asked to check their current supply and order any additional items to cover the Easter period.
People should also check the opening times of their local pharmacies and, in the event that those nearby are closed, know which other sites in the area will be open.
The Easter opening hours for all pharmacies in Bath and North East Somerset, Swindon and Wiltshire can be found online at bswccg.nhs.uk.
