233622 tn?1279334905 The clearance of R-warfarin is generally half that of S-warfarin, thus as the volumes of distribution are similar, the half-life of R-warfarin is longer than that of S-warfarin. The half-life of R-warfarin ranges from 37 to 89 hours, while that of S-warfarin ranges from 21 to 43 hours. Studies with radiolabeled drug have demonstrated that up to 92% of the orally administered dose is recov-ered in urine. Very little warfarin is excreted unchanged in urine.
Avatar f tn The half-life of a drug is how long it takes for half of it to be eliminated from the bloodstream. Hope that helps.
6298176 tn?1380134459 It has a very long half life, though I can't give you specifics. The dose and how long you were on it does factor in. Your doctor should be able to help you with your questions on this.
Avatar n tn Johnycat, thanks for your comments, but Xarelto is not approved for mechanical heart valve patients such as myself or Dream_ers's father. Plavix is sometimes given to mech valve patients, but when it is, it's used as an adjunct to warfarin and not as a substitute for it. Xarelto, not at all. Sorry you had so many problems with warfarin.
Avatar f tn I started 5 mg of warfarin on friday..today is sunday and i am seriously considering not taking my dose today at 10am. I started my schedule for taking it at 10am daily. When i took my first dose friday at 10am later that day right around 3 or 4 i started experiencing intense upset stomach.

Avatar f tn m afraid the infection will spread to my kidneys by then. Could I cut the tablet in half? Would taking a lower dose for a longer length of time work cure the infection and relieve the side effects? Thanks for any advice.
Avatar f tn DOES ANYONE KNOW IF WARFARIN CAN LOWER YOUR BLOOD COUNT AND AND ALSO LOWER CALCIUM AND VITAMIN D LEVELS?
Avatar n tn I am 62 years old and very active. I weight lift, jog, and ride a bike. Will I have to take warfarin all of my life or at some point can I discontinue it?
612551 tn?1450022175 Been on warfarin for years with stable INR results. Anyone have view on mixing warfarin and Coq10 meds?
Avatar m tn you have to think of the worse case senario of switching to warfarin having the warfarin be too strong and your wife getting a bleed of some kind. This could be in her GI track, brain etc. and can be very life-threatening and could cause huge hospital bills. So, depending on how long she will have to take the plavix for, and what she is taking it for, it may actually be less expensive to use the plavix.
942410 tn?1274047074 I was on warfarin once before when I was cardioverted a year and a half ago.( different Cardi). At this point my Cardiologist and I are working on keeping my INR at a theraputic level since I just "came off the table" from the ablation. I'm thinking after my protime on Monday I may be directed to lower the doseage(presently5mg daily) to something lower and / or begin having salads and more green veg in my food choices. I'm crazy for blueberries and they are super high in K...
Avatar m tn Pradaxa is taken twice a day, shorter life in the body and is cleared from the body quicker than coumadin (warfarin). With warfarin, Vitamin K is used to reverse overanticoagulation in patients, there is no antidote for Pradaxa. Warfarin a lot cheaper than Pradaxa. Good luck with your ablation. Hope you do well on Pradaxa! Best wishes!!
Avatar m tn I believe the correct (workable) way to take Warfarin is to find the dose level that keeps your INR in the desired range (usually 2 to 3) when you eat "normally".. just don't change your diet in any way that strongly affects you consumption of Vitamin K. Most foods do not contribute much "K", so keep it normal on those tht do, such a green leafy vegetables. I see no relationship between Warfarin and you leg problem.. are you on other medications?
Avatar m tn t know how warfarin is affecting your life style. I have been on warfarin for years and had no concerns about running and bike riding, and using power wood working tools. All of these activities puts one at an increased risk of a cut and bleeding, but I simply take the risk. On the other hand, I don't sky dive, or pick fights ....
Avatar m tn Hello, Dermatitis, urticaria, alopecia, rash, bullous eruptions, pruritus, and pallor have been reported infrequently with use of warfarin. If you are having these symptoms after use of warfarin then you can talk to your physician and get dabigatran prescribed as an alternative to warfarin. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.

Avatar f tn ?? Does anyone know the Half life of SUBOXONE - Beprenorphine.? I HEARD it was 70 hours, but that's what I heard....unsure if that is even accurate?
535882 tn?1396576685 whats the half life for syntriod. about how much time does it take to build up in you and also leave your system?
1569985 tn?1328247482 I take my warfarin before bed, so my time off warfarin is more like 1.5 days than two days. I go back on warfarin right after the exam, may take 7.5 mg instead of the usual 5 mg to get back on INR faster. I believe being off of warfarin increases my risk of a clot, but the risk is still low. Anyway, I split the difference toward the side of limiting clot risk while slightly increasing the risk of bleeding due to (minor) surgery.
