I've been on antibiotics (trimethoprin) since Friday (for a UTI) Still feeling rough and not right so went back to the GP earlier and she felt I needed a different anti-b and has given me Macrodantin. I was just about to start them and read through the leaflet,but the possible side effects are really grim and frightening-permanent neurological damage,lung problems,extreme changes of mood amongst others. I know that side effects are usually not common ,but I'm fairly sensitive to medication,have ropey lungs at best and am generally depleted from years of breastfeeding (side effects more likely of you are anaemic or low in vit B).Honestly I wouldn't give my dd this unless she had a life threatening condition. However I feel horrible and just want the UTI to be sorted out, I'm worried that I do need a tailored antibiotic to shift this as its not responding to the trimethoprin. AAargh.Feel really stressed as not sure what to do-any advice welcome.
