What is involved with desensitization therapy when one's reaction to bee stings is anaphylaxis?

Venom allergy shots: Venom immunotherapy (venom shots) is recommended for patients with systemic reactions such as anaphylaxis to stinging insects. Once testing has determined which stinging insects someone is allergic to, gradually increasing doses of venom are injected in the allergists office according to varying schedules. Once the maintenance dosage is reached injections are generally given every 4 to 8 weeks.
