A drug allergy occurs when a drug component interacts with the human immune system. It is also known as drug hypersensitivity reaction. Allergic reactions to drugs fall under the class of drug hypersensitivity reactions that are mediated by IgE. Recognized risk factors for drug hypersensitivity reactions include gender, age, illnesses, and previous hypersensitivity history to related drugs. Drug allergy is generally diagnosed clinically. Tests like skin tests is carried out in laboratories as it offers high specificity. Treatment is largely helpful and includes termination of the wrong medication, indicative treatment, and patient learning. For instance, patients with allergy from penicillin are advised to avoid any carbapenems and cephalosporins drugs for safer health.
The global Drug Allergy Market can be segmented based on diagnosis, type, treatment, and end-user. In terms of diagnosis, the market can be categorized into blood tests, skin tests, patch test, and others. Based on type, the global drug allergy market can be bifurcated into immunologic and non-immunologic. Immunologic is divided into type I, type II, type III, and type IV reactions. Non-immunologic allergy is divided into predictable and unpredictable allergies. Predictable allergy can be due to multiple reasons such as pharmacologic side effect, drug-drug interactions, secondary pharmacologic side effect, drug toxicity, and drug overdose. Unpredictable allergy can be due to intolerance, alterations in the metabolism, and idiosyncrasy reactions. In terms of treatment, the market can be segmented into corticosteroids, antihistamines, treatment of anaphylaxis, withdrawal of the drug, and others. Based on end-user, the global drug allergy market can be segmented into hospitals, medical research centers, clinics, academic institutes, and others.
