Penicillin Testing

Around 10% of patients in the United States have a documented allergy to penicillin or amoxicillin.  But, many of these same people are incorrectly diagnosed or lose sensitivity over time. At WinnMed, we offer testing to determine if you truly have a penicillin allergy, or if you are safe to take this class of antibiotics.

Venom Immunotherapy

Bee sting allergies can cause potentially life-threatening reactions. Fortunately, an epinephrine pens isn’t your only treatment option. At WinnMed, we offer venom immunotherapy, a highly effective treatment for bee sting allergies.
