Hello,
You may take Vitamin C along with the prescribed antiallergy treatment. Vitamin C is a general anti-allergy supplement. It helps stabilize mast cells so they are less likely to release histamine.So it can be used for prevention and treatment of allergies.
I hope that helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.Kind regards.
