After being labelled 'Failure to Thrive' yesterday my 9 week old DD was prescribed Losec for her silent reflux. This comes after spending the last almost 2 weeks on Zantac which seemed to help the first few days but not at all after that so my GP said Losec it is from now on. Thing is she was mighty sketchy on the dosage, had a bit of a search on her computer and decided on 2.5mg. The information the computer gave us was 10-20mg for 10-20kgs so I assumed this meant 1mg per 1kg? That was in the tablet form though and we have the composition but I don't think that would change things? Anywhoo my Dr admitted she wasn't quite sure on the dosage and that if the pharmacist needed her to change anything to just call and she'd speak to them or send a fax through etc.. When I called the pharmacy to see of they made the composition, the pharmacist talked me through it, asked her weight etc and without asking what was prescribed did her calculations and said DD required 5mg which would be 2.5ml of the composition which is 2mg:1ml. As DD is just under 4.1kg, that sounded about right.. When I went in to pick it up and gave her the script she came back and said the Dr has prescribed 2.5mg so that 1.5ml... But I'm worried I've got the incorrect dose as my Dr really has no idea about Losec and it's dosages etc??

Does that sound right? 2.5mg? I am normally not one much for medication, takes alot for me to medicate myself even so I definitely am not wanting to up her dose if it's not required but at the same time her GORD is severe, she's only put on 970 grams since birth, won't take a proper feed and screams in pain most of the day so I definitely don't want to waste any time under dosing her and risking it not working because of this.

Most of what I'm reading on the net are infants on doses of 10mg or more.. Not sure if that's the tablets or composition though and if it makes a difference? I'm thinking it shouldn't be different between the tablet and composition, it's the same medication but obviously this is nowhere near my expertise, I haven't a clue except for what I've read!

I hope this lengthy ramble makes sense to someone and that someone can help me figure this out.. I'm planning on calling the pharmacist this morning and asking her but I don't want to cause more confusion by not absolutely knowing what I'm talking about..

Can anyone help please?
