Hong, yes, some of us can understand; Merck Pharmaceuticals stopped manufacturing our son's Emergency 24 hour injection, due to cost of production, and they couldn't even provide the name of a generic or other substitute. This was after our son was first diagnosed and almost died, so we were so panicked! He absolutely needed this medication, and they (the company) stopped manufacturing it - I was irate! To say the least. Luckily, we found another drug (an 8 hour one) that we could get. Try looking over the internet web sites to possibly buy florinef; maybe mail order companies can distribute worldwide.
