Drugs used in the management of insect bites, venomous snakebites, and anaphylactic shock or reaction work through different mechanisms of action to alleviate symptoms and prevent further complications.
1. Insect bites: Antihistamines such as diphenhydramine or cetirizine are commonly used to reduce itching, swelling, and redness caused by insect bites. These drugs work by blocking the action of histamine, a chemical released by the body in response to allergens like insect venom. Corticosteroids such as hydrocortisone can also be used to reduce inflammation and itching at the site of the bite.
2. Venomous snakebites: Antivenom is the primary treatment for venomous snakebites. Antivenom is made from antibodies that neutralize the toxins in snake venom. When administered promptly, antivenom can prevent the spread of venom throughout the body and reduce the severity of symptoms such as pain, swelling, and tissue damage. In some cases, pain relievers and antihistamines may also be used to manage symptoms.
3. Anaphylactic shock or reaction: In cases of severe allergic reactions, such as anaphylactic shock, epinephrine (adrenaline) is the first-line treatment. Epinephrine works by constricting blood vessels, relaxing airway muscles, and increasing heart rate to improve blood flow and oxygen delivery to vital organs. This helps to reverse the symptoms of anaphylaxis, including difficulty breathing, low blood pressure, and swelling of the face and throat. Antihistamines and corticosteroids may also be used to reduce inflammation and prevent further allergic reactions.

Insect Bites
- Antihistamines: Block histamine receptors, reducing itching and swelling. e.g., diphenhydramine, loratadine
- Corticosteroids: Reduce inflammation. e.g., hydrocortisone cream
- Local anesthetics: Numb the area, reducing pain. e.g., lidocaine
Venomous Snakebites
- Antivenoms: Antibodies that neutralize the venom's toxins, preventing systemic effects. e.g., Antivenin Crotalidae Polyvalent
- Vasopressors: Increase blood pressure and reduce shock. e.g., epinephrine
- Anticholinergics: Block the effects of acetylcholine released by the venom, reducing nausea and vomiting. e.g., atropine
Anaphylactic Shock or Reaction
- Epinephrine (adrenaline): Causes bronchodilation, increases heart rate and blood pressure, constricts blood vessels.
- Antihistamines: Block histamine receptors, reducing itching, swelling, and mucous membrane inflammation. e.g., diphenhydramine
- Corticosteroids: Reduce inflammation and prevent further allergen-induced reactions. e.g., dexamethasone
- Bronchodilators: Relax airway muscles, making breathing easier. e.g., albuterol
- Oxygen: Provides additional oxygen to vital organs.
- Antihistamines: Block histamine receptors, reducing itching and swelling. e.g., diphenhydramine, loratadine
