Manifestation of drug allergy

Drug allergy (ICD code 10: Z88) is based on intolerance reactions caused by various mechanisms. These mechanisms include immediate type reactions and delayed reactions, which are immunological processes involving antibodies, and those substances that are associated with cellular immunity.

The main reason for an allergic reaction is that the body recognizes the active ingredient of the drug as foreign. As a result, the immune system launches defense mechanisms, producing class E antibodies that release the inflammatory mediator - histamine, which causes clinical manifestations allergies.

Due to the large number of types of reactions, drug allergies can be very diverse in appearance and vary greatly in intensity.

Sometimes, the side effects that occur after taking the remedy can be difficult to distinguish from a true allergy. As a rule, side effects are most common and are associated with overdose. medicinal product and not with the immune system.

The second difference is that the severity of adverse reactions increases with dose, while for people with allergies it does not even a large number of the drug can cause an allergic reaction that can range from minor symptoms to a life-threatening situation.

Theoretically, any drug can cause an allergy, but the most common reactions are to:

  • non-steroidal anti-inflammatory drugs: ibuprofen and indomethacin;
  • preparations for normalization blood pressure such as ACE inhibitors (angiotensin converting enzyme);
  • drugs used to relieve rheumatic pain;
  • antiepileptic drugs;
  • insulin;
  • muscle relaxants;
  • neuroleptics;
  • vitamins;
  • quinine-containing products;
  • and even herbal homeopathic preparations.

Drug allergies can be caused either directly by a drug, in the case of penicillin, vaccines, insulin, and intravenous drugs that directly affect the immune system, or indirectly, as a result of taking a histamine-releasing agent.
