Warfarin Overview

Warfarin (also known by the brand names Coumadin, Jantoven, Marevan, Uniwarfin) is an anticoagulant normally used in the prevention of thrombosis and thromboembolism, the formation of blood clots in the blood vessels and their migration elsewhere in the body, respectively. It was initially introduced in 1948 as a pesticide against rats and mice, and is still used for this purpose, although more potent poisons such as brodifacoum have since been developed. In the early 1950s, warfarin was foun...

warfarin and roxys
1 Reply RSS
If u take warfarin and take alot of roxys can it raise your inr level to the piont the inr level Can be dangerous ## Hello, Brown eyes! How are you? No, Oxycodone hasn't been known to do that, though it is recommended that a patients INR always be checked within a few days of starting any new medication, since there's no way to predict exactly how anyone may react to something. The FDA classifies Oxycodone as being a narcotic analgesic, so it has the potential to be habit forming and may cause side effects, such as nausea, dizziness, drowsiness, dry mouth and constipation. Warfarin may cause side effects, such as nausea, dizziness, headache, increased risk of bleeding and easy bruising. Have they both been prescribed for you?

Coumadin vs warfarin
31 Replies RSS
My mom was on coumadin for many years but then her insurance company told her she had to take warfarin as this is the one they would pay for. Is there really any different in these two drugs? It seems to me that she has been having more problems with the warfarin (keeping this medication at the right level) than the coumadin. I was told they were the same medications and do the same. I just wanted to know if some people have difficulties taking warfarin vs coumadin??? Thanks. ## No, they work exactly the same for me. I have been taking one or the other for 3 1/2 years because of 2 pulmonary embolisms. I take 10mg a day. At times I go up and down but have been steady for a couple months now on warfarin. Food will change the way it works. Salads and some other greens really mess things up...

I have had chronic severe back pain for approximately 30 years. I have bouts where I can hardly walk, currently I am in that state right now. A friend of mine says she takes this herbal dietary supplement for her severe back and neck pain. I am wondering if I can take the same even though I am on a regimen of warfin due to having had blood clots approximately seven years ago? I also see a chiropractor approximately every two weeks faithfully. ## Hello, Cindy! How are you? No, it is not safe for you take this supplement with Warfarin. It contains plum flower and ginseng, the latter of which also causes blood thinning. The FDA lists the typical side effects of Warfarin as possibly including nausea, dizziness, headache, increased risk of bleeding and easy bruising. Is there anything else I...

Hello, I cannot find any information on taking the supplement "Sam-e" (S-Adenosylmethionine) with warfarin. would love to find out if this can be taken while on a blood thinner ## Hello, Diana! How are you? It isn't advisable, the Mayo Clinic notes that SAMe can affect your risk of bleeding when taking with blood thinners, such as Warfarin or anticoagulants. The FDA lists the typical side effects of Warfarin as possibly including nausea, dizziness, headache, increased risk of bleeding and easy bruising. Is there anything else I can help with?

INR dropping though warfarin dose going up, also leg spasms-what's going on?
2 Replies RSS
This is a bit long, sorry. I know it takes awhile to get the dose right, but this seems kinda weird to me, particularly since I'm getting somewhat conflicting answers from different doctors. I know I'm not missng doses, I have a pill box I use and an alarm set to go off and remind me to take it. The doctors at the blood clinic don't seem overly concerned, but they have said that they usually get people at a theraputic level faster than I'm going. I don't really take any other meds, I had a few Norco (hydrocodone acetomenophen) prescribed by the ER for a really bad headache a few days after I got out of the hospital and very rarely will take a dose for back pain, but not very often. I've taken six doses in the past five weeks, hardly regular use, and none of them ...

pro time at 300
1 Reply RSS
My Dr. Tested me today. I have been taking coumadin for over one month @ 5mg one day, then 6 for two, and repeating. My level was 300! That seems high to me as my goal was 200. My Dr. Told me he didn't need to see me for a whole month now, and I am concerned my levels will keep going up! Any feedback? Thank you! ## Hi Zena, If I had this concern I'd probably give my doctor a call about it right away, just to be on the safe side. However for reference, I did come across an article on PubMed that may help explain what prothrombin time levels are considered to be in the normal range. And apparently if you are taking Coumadin to prevent clotting, it is likely that your doctor will want your INR levels to be somewhere between 2.0 and 3.0 (I'm thinking this translates to 200 or 30...
