Update! I had a patient tell me that she was allergic to sulpha, but wanted to go on Diamox. Most people with sulpha allergies tend to do fine with it, but you don’t want to be THE ONE who doesn’t! So, her doctor gave her a skin scratch/patch test! She was in the clear! I thought that was quite clever. Something to consider if you have sulpha allergies, my friends. 🙂 Diana
