Riveroxaban and warfarin allergies

Hi - well I've finally taken my last rivaroxaban tablet on Thursday and am now on warfarin. Most side effects are wearing off and i was feeling much better. I say was because i am now experiencing an allergic reaction. On riveroxaban and the other NOACs which I've taken over the last 7 weeks i had a definite allergic response - itching head and prickly lips. On Thursday whilst i was taking both warfarin and riveroxaban i had a definite allergic reaction a few hours after taking warfarin and now, all day Sunday it's driving me mad. I'll go to the gp tomorrow but does anyone know if a reaction to riveroxaban could get worse having stopped it? If I'm allergic to warfarin I don't know what to do next.

I do not take either of those but Amiodarone made me itch like mad. It reduced over time.

Never had an allergic reaction to warfarin, but we're all different... I would have thought an allergic reaction would stop if you stop taking the thing you're allergic to, but bodies are weird and wonderful things, best ask the gp!

Thanks - gp says there's no way of knowing if it's warfarin or not (i had read you could do a scratch tesl) she's doubled the cetirizinevand said to also take the drowsy piriton at night and see how it goes.

How much are you taking and what is your INR?

Hi I'm only on 2 pills per day - my inr came in at 2.9 after an initial loading dose of 5. Im taking the 0.5 pills as they don't have ant dye in so can't be allergic to that.

Do not know whether that is a high or low dose, as I am taking Marcumar, similar, but not quite the same. Allergy still there?

Hi - thanks for asking. Yes the allergy is still here. My gp has referred me to a haematologist and I've asked to go private to see her faster. What is marcumar? Would it be a substitute for warfarin? They've mentioned a couple of other drugs but say they're very difficult to get hold of however no one has mentioned marcumar.
