When is a reaction called anaphylaxis? I had med allergy including hives, flushing, rash, but nothing else. Was that anaphylaxis and do I call it that

Anaphylaxis. Anaphylaxis=when your health suddenly changes-minutes to hours after a food, medication, allergen exposure, insect sting-such that you experience one or several of the following: swelling, hives, nausea, vomiting, flushing, difficulty breathing, lightheadedness, fullness in the throat, fast heart rate. It sounds as though you had a mild systemic reaction pls get evaluated for drug allergy.
No. Anaphylaxis would also include wheezing, difficulty breathing and low blood pressure. It is then anaphylactic shock. You describe a severe reaction. You should probably talk with your doctor about carrying an epi pen.
