Retail clinics are healthcare facilities located within retail stores, such as pharmacies or supermarkets. They provide basic medical services for common illnesses and minor injuries, often without the need for an appointment. These clinics are typically staffed by nurse practitioners or physician assistants, making them a convenient option for patients seeking quick care. Patients can visit retail clinics for services like vaccinations, physical exams, and treatment for conditions such as colds or allergies. They usually have extended hours, including evenings and weekends, making them accessible for those with busy schedules.
