Taking Generic Cumadin After Knee Surgery. Protime Level Normal. Advised Heprin Shots

My husband started taking generic cumadin after knee surgery last week. His Protime level was 1.2 per the nurse sticking his finger . Isn t that too thick? His reading is being sent to his surgeon. His surgeon ordered Heprin shots while at the hospital and also started the generic cumadin. Just wondering about the 1.2.

Hello

As you have said that your husband underwent knee surgery , and started on warfarin , but INR is 1.2

Normal INR is 1.0-1.1 , in knee surgeries as that leg will be static for long time , the calf muscles below the surgery knee has more tendency to clot , since the leg is static for long time

The ideal INR after knee surgeris is 2.2 to prevent calf clots and hence prevent lung clots

So because of low INR that is 1.2 , your doctor advised heparin shot to make blood thin

I would recommend to increase the dose of warfarin after your doctor consult , and different drugs and food have a lot of interactions with warfarin , so be careful

Hope this is helpful to you

Take care
