I had a patient today that came for routine tests at clinic. Patient lips swollen on R side. According to patient he received phenergan 25mg from pharmacy 2 hours earlier and drank 2 tablets. After aprox 15 minutes swelling got worse. Tongue not swollen, patient didnt struggle to breathe. I gave 1ml of 1:1000 of Adrenaline. Swelling of lips didnt improve, patient didnt want to stay as he was in s hurry. Your thoughts on this patient? Anything else that I could have done for this patient?
