Hi All,

I  am new on here and hoping for some advice.I have to stop my warfarin 5 days before my surgery and self inject TInzaparin(HEPARIN) ON each of the last two days before my surgery. the Dr prescribed 10,000units plus 4500units for each day. The hospital pharmacy have gven me 4 syringes(2X10,000units and 2X 4500units). Forgive me if i appear to be a bit thick, but I a anxious to get it right. So - do I have  to inject one of each dose on each of the lst two days before mu Op?

    Hi there Robert,

    I had to inject inject myself with those tinzaparin injections for 2 months after I had my second bloodclot in 7 years around Christmas time and I too am on warfarin for life. From reading what your doctors said I would think it would be one of each per day but if your unsure best advice is to contact your doctor. Also, best to inject into your stomach you don't really feel it there. Hope ive been some help.

    Yes, one of each on each of the two days; so that you're injecting 14,500 per day for the two days prior to your op. But if you still feel anxious, contact your doctor. All the best with your surgery.

    Hi Robert, 

    I am on Warfarin for a lifetime. Warfarin remains in our bodies for about four days after stopping it. However, two days after stopping Warfarin, the levels are unsafe and you need to start taking Heparin. We need to be very careful while making transitions from/to Warfarin. When you start taking Warfarin again there is also a delay of around 4-6 days until your coagulation time reaches the proper levels. I believe you should be using Heparin during this delaying time in transition from Heparin to Warfarin, after surgery. Doctors will surely prescribe it in Hospital.
