As with other unfavourably susceptible responses, these medication-hypersensitive responses can happen when the body’s immune framework becomes sensitized to a substance in the medicine, perceives it as an outside intruder, and discharges chemicals to safeguard against it.

Immune System Mistaken Identity

Our immune framework encourages typically us to protect ourselves from diseases, battling foreign invaders like viruses, bacteria, parasites, and other dangerous substances. With medication sensitivity, our immune framework mistakes a medication entering our body for one of these intruders.

Antibody Response and Inflammation

  • Drug Provocation (challenge) tests (DPTs) are utilized to objectively reproduce the patient’s symptoms and allergies using the speculated specialist. A positive test does not affirm hypersensitivity. DPT includes managing the medication utilizing moderate, incremental dose escalations at fixed time intervals and observing for the presence or absence of an objective response. It is risky to the patient and ought to be done under the strict supervision of clinicians/attendants with sensitivity training and resuscitative equipment available.
