What method does drug allergy have to treat

In case of drug allergy, the sensitizing drug should be stopped immediately. The patient should take cetirizine, loratadine, etc. orally, which can effectively prevent the release of histamine substances and play an anti-allergic role. At the same time, glucocorticoids such as dexamethasone can be used for treatment. Adrenaline can be injected into severe allergy.
