Vitamin C and calcium gluconate both have the effect of improving capillary permeability and vasoconstriction, so vitamin C and calcium gluconate can cure urticaria, which can alleviate the discomfort of urticaria patients to a certain extent. It is recommended that once urticaria patients are diagnosed, they should actively follow the doctor’s instructions for treatment to avoid complications such as shock, respiratory obstruction and gastrointestinal bleeding.
