usually if an adult gets a fever over 101f we suggest he or she seek medical attention. that said you ask a great question. no one taking warfarin should take an over-the-counter "blood thinner" or nonsteroidal anti-inflammatory (nsaid) pain reliever. these include aspirin (and products containing aspirin) ibuprofen and naproxyn sodium. the main over-the-counter pain a fever medication for people taking warfarin is acetaminophen (tylenol). however given that your 20 year old is on warfarin i'd suggest you consult his or her primary health care provider about both the fever and about what medication would be safe for him or her to take. because i don't know your child's medical history the information i give here is strictly generic in nature and should not be construed as instructions or medical advice. take care!
what can you give a 20 year old on warfarin for a fever of 102 on a mouth thermometer
