So long as an allergic reaction is non-life-threatening, an urgent care clinic can easily handle it. In fact, urgent care is the best place to go for minor allergic reactions, as urgent care can see you immediately without the need for an appointment. You can just drive over, walk right in, and get treatment right there. They’ll have you back home and feeling better in next to no time! You can bring in your child if they’re the one experiencing a reaction, as anyone of any age can be treated at urgent care.
