MVH, is the pharmacist from Paragon? Gosh, I got the same info and was told that once you took out the tablet, it will dissolve in the air, hence to dissolve the entire tablet in 10ml of water then feed baby 5ml.
I checked with two pharmacists from Paragon Guardian and both told me the same thing. I called up my PD, he said for losec mups can break into half and keep the other half in fridge. I tried out one tablet, broke into half, kept in air-tight box and put in box in fridge, the next day, the tablet is still as dry and solid,no sight of melting.
The next box of losec I bought from Parkway Parade, this time the pharmacist there told me I can break it up and store in fridge. I have been doing this and no problem so far.
The losec mups will turn black if not consume on the same day after it melts.
