If you are, can you let me know what dose you're on?
I've been switched from Tinzaparin to fondaparinux due to osteoporosis, but only at 5mg per day which I think is too little for my weight (70k) - leaflet says this is correct dose for 50Kg or less.
Lovely thought it would be to lose 20kg in the next few weeks, I'm thinking it's not likely!
