Oh, and mother 1991, Neptazane can sometimes be substituted for Diamox if you’re sensitive to sulfa drugs. It is still a sulpha derivative, but if you work closely with your doctor, you may be able to squeak by. Diamox (and Neptazane) are carbonic anhydrase inhibitors, not HCTZ drugs, so you may want to see if it could help you. Fingers crossed. 🙂
