Dissolve 1/2 a tab in some cooled boiled water and give 2 times a day 12 hrs apart before a feed.

DS1 was on from 5 weeks till nearly 8 months. I got jack of trying to properly dissolve the tablets so went to a compounding pharmacy and got a liquid made up, is $ but much easier (well apart from trying to get a baby to take bitter medicine) they did try and flavour it for me but due to the ph of the medicine they did not hava many choices so was a slight improvement (think pina colada flavour LOL).

Good luck I hope it helps you wont see an immediate huge improvement but we saw suble with in 2 days and improvement took about 5 - 10 days for us.
