I am not a doctor. You need to see a doctor to get a prescription for Diamox. You don't have much time, so good luck getting in to see one. Most will not be experienced with Diamox (Acetazolamide), but I think they can look up the dosage and write a prescription.

You should take it starting two days before you hike, small dose twice a day. If the prescription is any higher than 250 mg total per day, I'd be careful. Half of that is my max. It has weird side effects, like tingling/buzzing fingers, and beer and carbonated drinks taste bad.

I think you can take it with the other things you mentioned, but be sure to ask the doctor.
