Save time in the waiting room with online check-in
When illness or injury strikes without warning, MedStar PromptCare is here for you. You never need an appointment to see an expert provider at our urgent care center. Just walk in or save your spot in line with online check-in.
We are more than a walk-in clinic. Our team of providers diagnoses and treats non-life-threatening illnesses and injuries for patients of all ages. We have X-ray services and laboratory testing available on-site for common illnesses (strep, mono, influenza, urinary infection, and pregnancy). If your condition needs further testing such as blood tests or cultures, we will have most results in 48-72 hours. Some advanced testing for serious illnesses may require a referral to a nearby hospital’s emergency department.
We are conveniently located near the I-270 technology corridor in Gaithersburg, MD, in the Shops at Potomac Valley on Darnestown Road. Find us directly across from Starbucks and adjacent to Quince Orchard High School. We have ample free parking available just outside the door.
Should you need ongoing care, we are right next door to the primary care physicians from MedStar Medical Group at Gaithersburg. We will even help you make an appointment.
MedStar PromptCare at Gaithersburg is committed to providing convenient, coordinated care with extended evening, weekend and holiday hours. Stop by to see us or use online check-in to reserve your spot in line.
