I agree that it is important for patients to call the phone # on the RX receipt, soon after you have an allergic or adverse reaction.
Sadly, I learned later that Med Watch only needs one or two well documented reports. Without the prescribing Doctor's report, the patient's report means very little.
My husband should have taken me to my Doctor and made him look at what that drug was causing, then taken me to the ER, to have blood work to prove that it was in my system.
Maybe that is a requirement of being a well documented case.
