What Is Anaphylactic Shock

How do allergy medications work?

Anaphylactic shock, also called anaphylaxis, is a severe, life-threatening reaction to certain allergens. Body tissues may swell, including tissues in the throat. Anaphylactic shock is also characterized by a sudden drop in blood pressure. The following are the most common symptoms of anaphylactic shock. However, each person may experience symptoms differently. Other symptoms may include:

  • Itching and hives over most of the body

  • Feeling warm

  • Swelling of the throat and tongue or tightness in throat

  • Difficulty breathing or shortness of breath

  • Dizziness

Best Treatment To Manage Allergies Long Term

Immunotherapy is a great option for anyone who suffers from severe allergy symptoms, especially for those with year-round allergies. Immunotherapy works by exposing you to gradually increasing levels of an allergen to help your immune system slowly build a tolerance, relieving allergy symptoms and even preventing new allergies from developing.

Allergy shots are one form of immunotherapy that require frequent office visits to be administered by a doctor. Allergy drops are a revolutionary form of immunotherapy that can be taken under the tongue from home each day to relieve allergy symptoms long term. Both allergy shots and allergy drops can be prescribed by a doctor after specific allergies are determined by an allergy test. This is a long term approach to allergy relief and management, with most patients taking allergy shots or drops for a period of three to five years.

Best For Treating Itching And Nasal Allergy Symptoms

Antihistamines work by targeting and blocking histamine, which is the chemical substance your body releases when exposed to an allergen, such as pollen or pet dander. Antihistamine treatments can take the form of pills, liquid, nasal spray, or eye drops. Once antihistamine medications are in your bloodstream, they can quickly reduce symptoms caused by allergens and prevent the release of histamines in the first place.

Taking antihistamines before or during exposure to an allergen can help limit and even prevent allergy symptoms. Antihistamine pills are most effective against itching, sneezing and runny nose, while nasal sprays are primarily designed to relieve congestion and pressure. Its important to note that certain antihistamine, especially older drugs, can cause drowsiness and dizziness, so you should be careful to avoid certain activities like driving after taking some antihistamines.

Allergy Types Tests And Treatment

The list of possible allergens may be limited only by the number of protein molecules in existence. However, some do turn up more than others. Many people suffer from seasonal, respiratory allergies, usually in the spring or fall and caused by pollen, mold and dust. Some people suffer from food allergies. Common allergenic foods are peanuts and shellfish. Of injected allergens, penicillin and insect venom are common offenders.

Allergists use a variety of diagnostic techniques to determine if a person is allergic. Unfortunately, the safest and often the most effective tests are not completely reliable by themselves in identifying if a substance is the cause of a patient’s symptoms.

The most common test, the scratch test, consists of applying a diluted extract of the possible allergen to the back or arm, and then scratching the skin with a needle. If the patient develops a certain degree of swelling or redness in the scratched area, the existence of IgE antibodies to that allergen is indicated. Blood tests are another avenue of diagnostics, especially in small children. With small children, the scratch test is used less often because the possible allergens used in the test may actually trigger a reaction in a child who has not been exposed to that substance before. Neither the scratch test nor the blood test is 100 percent accurate, but the results, taken together with a patient’s medical history, can help the doctor or allergist with a diagnosis and treatment plan.

  • Certain types of antidepressants. Tricyclic antidepressants such as amitriptyline and lofepramine may interact with antihistamines. Other antidepressants such as moclobemide.
  • Antacids, which may interfere with the way the antihistamine is absorbed, thus making it less effective.
  • Other tablets which make you drowsy, as the combination may be too much. For example opioid painkillers or benzodiazepines and Z drugs.
  • A group of medicines called antimuscarinics. This includes medicines such as hyoscine, oxybutynin, propantheline and tolterodine. Because these medicines can give you similar side-effects, such as a dry mouth or problems passing urine, the combination may make the side-effects more serious.
