Question : I am on Warfarin (8 mgs. now-adjusted according to INR results). Was out in the sun today, and have developed a SEVERE red rash all over my body-face, chest, down my whole back and legs. It is not itchy, but is everywhere (looks like measles). Should I be concerned? (Am leaving on vacation tomorrow morning-clinics all closed now)

The rash was bad on my face which I thought was a heat rash-it was after I had a warm bath that the rash showed up all over my body.

Detailed Answer:
Thanks for asking on HealthcareMagic.

I have gone through your query and understand your concerns. If the INR is normal I would not think in lines of bleeding tendency. If I assume it not to be due to photosensitivity, it is more likely to be due to some viral infection. Measles in one such viral infection. I would not insist you to ignore it especially when you are about to leave on a vacation. I would insist you to upload an image. It would have been even better if you could get yourself clinically examined by a doctor.

I would wait for your response.
