For individuals with severe insect sting allergies, a single sting can trigger a life-threatening reaction known as anaphylaxis. Fortunately, a highly effective treatment called venom immunotherapy (VIT) is available—and at WinnMed, patients can receive this specialized care under the expert guidance of Michael D’Netto, M.D., a Mayo Clinic Health System board-certified Allergist and Immunologist.
Venom immunotherapy is a long-term treatment that works by gradually desensitizing the immune system to insect venom. It involves regular injections of purified venom extracts from stinging insects such as honeybees, wasps, hornets, and yellow jackets. Over time, the body builds tolerance, significantly reducing the risk of a severe allergic reaction with future stings
“Venom immunotherapy is more than just symptom management—it’s a preventive therapy that can save lives. This is done by essentially re-programming the immune system to no longer react to venoms in an allergic manner,” says Dr. D’Netto. “For patients who’ve experienced anaphylaxis due to one of the aforementioned stinging insects, this treatment offers peace of mind and long-term protection.”
The treatment typically spans 3 to 5 years, with a build-up phase followed by a maintenance phase. Studies show that venom immunotherapy is 95–98% effective in preventing systemic allergic reactions to future stings
Dr. D’Netto begins with a comprehensive allergy evaluation, including skin or blood testing, to confirm venom sensitivity. From there, he develops a personalized treatment plan tailored to each patient’s needs and risk factors.
If you or a loved one has experienced a serious reaction to an insect sting, talk to your provider about a referral to Dr. D’Netto. Venom immunotherapy could be the key to a safer, more confident life outdoors.
