Hi everyone. Just self tested as I've got a headache and heavy cold and my INR has dropped to 1.3. Was 2.7 last week. I'm supposed to be between 3 and 4. Do I need to seek medical advice or will it be ok just to up the dosage when I take my warfarin tonight?
Also, is a plaster cast on my arm likely to have any effect on my INR because of the movement restriction ?
