On behalf of someone on another (US) site (they are posting from phone so not sure if they can get on here, register etc) - She has had back pain for 7 days and has been prescribed Methylprednisolone and Cyclobenzaprine - the Cyclobenzaprine is the one she is worried about WRT breastfeeding as there is not a lot of information on it. Her DD is 15 months old if that makes a difference - does anyone know of the effects of it or how long it will stay in her milk for?
