What is the max amount of alcohol I can consume in one sitting while on warfarin with an INR around 3.5? I am 21 so how much is safe?

Limit 2 drinks: I am unaware of any affect of alcohol on pro time of people on warfarin. However, being on warfarin renders one more at risk for bruising or bleeding if even minor injury occurs. Limiting ones drinking to only one or at most two alcoholic drinks makes sure you maintain all your faculties to avoid even small injuries. ...Read more

Go see your doctor..: Now! You didn't explain why you're taking Coumadin (warfarin) but we typically aim for inr 2-3 if for blood clot or atrial fibrillation or clotting disorder. We aim for 2.5-3.5 if you have mechanical valve. Inr of 6.1 is way too high. Your Coumadin (warfarin) dose needs to be held/adjusted & inr monitored closely until back into therapeutic range. 8 lb weight loss in 2wks is not normal either. Go see your doctor now! ...Read more

My INR is 3.3. I accidentally took a double dose of Coumadin today, i.e. an extra 10mg. I have been taking 10mg every day except 5mg one day each week?

See MD: See the MD prescribing your Coumadin to make some adjustments over the next couple of days. Also ask about switching to a novel anticoagulant that does not require monitoring and has less risk of bleeding. Rest and no vigorous activities that may cause bleeding. Good luck. ...Read more

If a pt has a high INR (2.1 & 2.2) but is not on Coumadin (warfarin) should a work up be done to determine the cause? Why? What would a work up consist of?

Absolutely: High INR indicates impaired blood clotting. It can be caused by advanced liver disease, severe infections, certain types of cancer, very large blood loss, and severe malnutrition. It definitely needs to be investigated if the cause is not obvious. ...Read more

Can I take my Coumadin (warfarin) at the same time as drinking alcohol?

Can I take my Coumadin (warfarin) at the same time as drinking alcohol?

Sure BUT!!!!: I would advise anyone on Coumadin (warfarin) not to drink and if so, to drink no more that 1-2 ounces of alcohol in a 24 hour period. The risk of falls and severe injury, bleeding and even death is too great. The physical and immediate act fo taking the dose with alcohol is probably not a major issue, but why would you do it? There are not many medications that I take more serious than using coumadin (warfarin). ...Read more

Is excessive sleep in an 80 years old a warning sign for a stroke? Given that we have high INR level? And trying to maintain it using coumadin (warfarin).

No.: Stroke does not have warning signs except for transient neurologic symptoms which are only recognized as transient in retrospect. Sleeping is not a warning sign nor is it associated with elevated inr. You should have had a frank discussion with your provider about the risks and benefits of Coumadin (warfarin) therapy using the chadsvasc and possibly hasbled scoring systems. ...Read more

Does Coumadin (warfarin) make you extremely fatigued? Is there a medication that is a blood thinner but you don't need an INR check?

Rivaroxaban.: Coumadin (warfarin) does not make you extremely fatigued unless you're anemic from occult bleeding because of a supratherapeutic (i.e., really high) inr. Make sure you stay on top of your inr and, if you're feeling really fatigued, to have your hemoglobin/hematocrit (which is your blood count) checked. Rivaroxaban is a blood thinner that doesn't require monitoring. Discuss with your pcp. ...Read more

My mother is 83, has a-fib & takes coumadin (warfarin). She likes to have greek yogart on her cereal. Does greek yogart have any effect on her INR count?

Unlikely significant: Greek yogurt is not a particularly rich source of vitamin k, so it's ok to eat when on coumadin (warfarin). Coumadin (warfarin) works by blocking vitamin k to thin the blood. Typically keeping with a diet that's normal for you, and allowing the physician to make adjustments in the dosage of coumadin (warfarin), is the best strategy. You shouldn't have to give up the foods you love just to be on coumadin (warfarin). ...Read more

Ussually: Ussually the inr is considered to be adecuate between 2, 5 and 3, so I am not clear why is 4 or 5, or may be I am missing something. There are many reasons for changes in the dosage of nmedications, that go from the medication it self (produccion, quality, efficacy, byoavalilability etc etc etc) to issues with the patient, again metabolism, interaction with food, medications and behavior of the medication within the body. The important issue is to keep the inr in the propper range. ...Read more

My mom is on coumadin (warfarin) and lovenox but her INR is only 1.3. She recently had a stroke nd dvt. Isn't she at risk of another stroke with low INR?

My mom is on coumadin (warfarin) and lovenox but her INR is only 1.3. She recently had a stroke nd dvt. Isn't she at risk of another stroke with low INR?

No: Lovenox provides anti coagulation while Coumadin (warfarin), (warfarin) which takes a long time to have a complete effect, as measured by INR, starts to work. She's not at increased risk. Make sure to look at the dietary restrictions and drug interactions with Coumadin (warfarin) which might be the reason the INR is still low. ...Read more
