Hi Falcon:

The Magic Mouthwash prescribed by my ENT and Radiation Oncologist can be filled at any drug store - they write down what they want included and the amount of each, on the prescription, and the druggest makes it. I did go to one ENT who told me I would have to have it filled at a Compound Pharmacy, but it was filled at a chain drug store in my city (grocery store Krogers Pharmacy). I watched as the pharmacist mixed the ingredients. I don't remember the cost, but it was far, far less than $42. Maybe check at a drug store, show them the prescription, and see what they say. Good luck, and welcome from julieann
