This is Dr. David
promethazine is Phenergan which is a first generation antihistamine
some people can have severe allergies to it
you can see an allergy and immunology doctor about it and get a skin test for promethazine to see if you have allergic.
some patients can have severe reactions such as seizures, stop breathing, bone marrow failure from it.
some doctors may not even want to test you for allergies because you could have another heart attack or severe reaction even if you have simple skin testing.
this should be put on your ALLERGY part of your medical chart so that no doctors will give you this medication in the future
