I Take 5mg Warfarin Sodium For Prosthetic Aortic Valve. I

I take 5mg warfarin sodium for prosthetic aortic valve. I have had no bleeding issues in about 20 years on warfarin. I am diligent with interactions. I have sinus pressure right now, causing mild earache and headache. My wife swears by pseudoephedrine for conjeston. I took one (60 mg) yesterday, with remarkable temporary effect. The box provides no warfarin interaction, and the pharmacist said there is no interaction. Would you concur for short term?
