Immunotherapy, often referred to as allergy shots or allergy drops, is a treatment option for individuals with allergies. It involves administering small amounts of allergens over time to desensitize the immune system and reduce the body's allergic response. Immunotherapy can be administered through injections (subcutaneous immunotherapy) or taken orally under the tongue (sublingual immunotherapy). It is a long-term treatment option that can provide lasting relief and reduce the need for medications.
