Is There Any Chains That Operate 24-Hour Pharmacies?

CVS Pharmacy, Walgreen's and Rite Aid all offer 24-hour pharmacies in certain store locations, as of 2015. The number of 24-hour pharmacies available from these chain stores depends on the city or state.

At CVS Pharmacies, one service provided to customers is the implementation of a variety of vaccinations for teens, adults and the elderly. These vaccinations include immunizations against the flu, shingles, pneumonia and meningitis. For some vaccinations, a patient requires an appointment, while others are provided to walk-in customers, says CVS.

CVS also offers Minute Clinics at select locations, where nurse practitioners and physician assistants provide a variety of services to adults and children 18 months and older. Some of these services include treating common illnesses, prescribing medications, performing physicals and giving advice on nutrition and lifestyle changes. When a patient visits the Minute Clinic, the practitioner enters all information gathered electronically to ensure that patients are referred to other doctors when necessary and all protocols are followed.

Walgreen's has a similar service available to customers, known as Healthcare Clinics. These clinics are open seven days a week, as well as on weeknights. Patients can walk-in for service or make an appointment before visiting the clinic. The clinic accepts most insurance policies or a patient can pay for the visit out-of-pocket, reports Walgreens.
