Signs of Wasp sting

Description

An insect sting that is part of the family of insects named hymenoptera. Some insects in this class are bees, yellow jackets, hornets, and ants. The wasp sting is similar to a bee sting. Wasps can also bite. Bites do not involve the injection of venom but can be very painful. Most of the symptoms are located at the site of the bite unless the patient is allergic to the venom. There can be cross reactivity between insects in the hymenoptera family. If the patient is allergic, a severe reaction can occur with swelling of the airway and/or low blood pressure. If untreated death can result.

Symptoms

Most symptoms are at the site of the sting including: pain, swelling, redness, increased warmth, tenderness. If the patient is allergic to the venom the following may be seen: rash, itching, swollen lips or mouth, difficulty swallowing, breathing problems, lightheadedness, fainting, weak pulse, coma, death.

Tests

A history and physical exam will be performed.

Treatment

Treatment is aimed at reducing the symptoms. The following treatments are used for a local reaction: removal of the stinger, antihistamines (diphenhydramine/Benadryl), nonsteroidal anti-inflammatory medications/NSAIDs (ibuprofen/Motrin or Advil, naproxen/Naprosyn), and pain medications such as acetaminophen (Tylenol). If the patient is having an allergic reaction the following medications may be used depending on the severity of the symptoms: antihistamines, epinephrine, steroids, intravenous fluids, and/or mechanical ventilation. Patients with significant allergic reactions should carry epinephrine (Epi-Pen) with them and know how to inject themselves. Rarely the site of the injury can become infected requiring antibiotics.
