Secondary lactose intolerance - will Colief do as well as SMA LF, only cheaper??

[oysterpots]

DS had the nasty norovirus just after Christmas and so we switched him to SMA Lactose Free. I saw the doctor last week about something else and brought the lactose intolerance up with her, asking how long it would last and whether we could get the excruciatingly expensive formula on prescription. Her answers were 6 weeks and no.

So we've already spent about £50 on formula over 3 weeks and I'm loath to spend the same again, but it occurred to me that Colief is lactase and only a tenner. Has anyone had experience of using Colief for secondary lactose intolerance? Does it do the same job?

i tried it and made my ds worse. If you are lactose intolerant it wont just dissapear like that. Unless there is something i dont know about with the virus??!!

My ds is 18 mnths and is allergic to dairy and intollerant to soya and sheep. He has goats produce. His formula cost £9.25 for a 400g tin and goes through 1 tin a week so know how expensive things can get

sma lf is cheaper than colief in the long run, and colief is a pain in the bum as you have to have had it in the bottle for at least 4 hours for it to work but no more than 12 hours or something... we got 10 tins of sma lf on prescription, which helped, but not alot as ds was on it for nearly a year. all in all, it is expensive but we found it was better to spend the money around £6 a tin then, than have the screaming and the inconvenience of colief.
