Hi, >A mother came in to our clinic today. She is a diabetic who's medication >is being changed to metformin (Novo-metformin)...{snip} I am not medically trained, but I know of metformin and it's been around for years, so I hope "new drug" was new to your client, not a totally new treatment? I know of a lady who took it while breastfeeding but her diabetes worsened and she had to go onto insulin (independent of her breastfeeding). Metformin can theoretically cause hypoglycaemia in the baby, as it is excreted in breastmilk, so the baby would have to be closely monitored and most doctors I know would be concerned about the baby's health. The mother should definitely be closely monitored to ensure she was on the minimum possible dose of the drug. I suppose going on to insulin is not something your client or her doctor would consider? Some diabetics I know would consider it worth it so the baby could be breastfed for say, three months, as breastfeeding can help protect a baby against diabetes. Sorry I can't be more positive :-( -- Anna (mummy to Emma, born 17th Jan 1995 and Alice, born 11th Sept 1996) Web Page: http://www.ratbag.demon.co.uk/anna Turnpike evaluation.
