Thanks. Got second opinion from another doctor today after 2 nights of no sleep again (since being on ranitidine has been sleeping brilliantly) and they said I can double it to 0.6 3 times a day and it can still be increased if needed! So my gp was full of it and poor baby would've been in pain for 2 weeks had I not questioned it! Hmmm....
You could ask your pharmacist if they can tell you the dosage:weight ratio. My Paed told me how many mg mine had to be on then I had to go away and work it out according to what suspension of meds:liquid the bottle I had was!
I do wonder if they are a bit cavalier in their calculations as 4 months later I've been told he's on the maximum dose for his weight now so he must have been OD'ing back at the start.
Posting here too as very desperate to get an answer! Anyone know what dosage of ranitidine babies can go on? I know its meant to change with weight. Saw gp yesterday who said baby is already on too high a dose so couldn't up it, despite baby discomfort again. He is 3 months and currently on 0.3 ml 3 times a day. He weights 5.7 kg.is is 10/150 oral suspension. Thanks!
