I take a medication, methazolamide, to treat glaucoma. I am from the US, currently live in Thailand, and have purchased the medication from Canada. Canada has had a shortage of the drug for 6 months, and the cost in the US has increased to $700 for a one month supply. Apparently the medication has few sources throughout the world. A pharmacist told me the medication was available in Taiwan but I need to be sure before I travel there to get it. Can someone suggest the best place I can call to get this information? I need to communicate in English. Thanks so much for any information.
