Allergic desensitization to drugs

"The Clinica has developed the technique of the basophil activation test to analyze in the laboratory possible allergies to drugs and thus correctly evaluate the convenience of carrying out tolerance tests".

Drug desensitization consists of administering to a patient the drug to which he is allergic.

It is performed when there is no adequate alternative to that drug treatment. The most frequent cases are related to antibiotics (especially penicillins) and anticarcinogens (especially platins and taxanes).

At the Clinica Universidad de Navarra we have extensive experience in carrying out desensitization with antibiotics and oncological drugs.

Desensitization is complex and requires the coordination of many people and services. It does not mean that the patient is no longer allergic, but rather that it "tricks" the immune system so that a reaction is not triggered.

When is drug desensitization indicated?

Drugs are capable of causing adverse reactions of all kinds, not just allergic ones. In addition, the drug is often blamed for a wide range of symptoms, which can be confused with an allergic reaction, but which are caused by a coincident cause.

Allergic reactions to drugs are unpredictable reactions of varying severity, some of which are life-threatening. Any medication can cause allergic reactions.

Most frequent indications:

How is allergic desensitization to a drug performed?

Desensitization with a drug is a procedure that carries some risk. For this reason, it is usually performed in the Intensive Care Unit (ICU).

If the patient needs to receive the drug in several cycles, as occurs with chemotherapy, and the first administration has been tolerated without incident, the rest of the cycles are administered in a simpler unit. Performing desensitization is complex because it requires the coordination of many people and services.

The duration can be between two and a half and six hours, depending on the type of medication and the degree of allergy of the patient. Normally, it is well tolerated and the appearance of adverse effects that prevent the completion of the drug dose is rare.
