- Both a generic and a brand-name medicine, warfarin oral tablet, is available. Jantoven is a brand name for a product (Coumadin was discontinued in April 2020).
- Warfarin is a blood thinner that is used to treat and prevent blood clots that can cause heart attack, stroke, or death. Blood clots in atrial fibrillation, cardiac valve replacement, venous thrombosis, and pulmonary embolism are all treated with it.
Why is Coumadin being discontinued?
Coumadin (warfarin sodium) pills of all strengths are no longer being manufactured. The termination is due to an unexpected production issue, not to safety or efficacy concerns, according to Bristol-Myers Squibb, Coumadin’s producer.
Which blood thinner is the cheapest?
Popular Anticoagulants Prices Warfarin (Coumadin, Jantoven) is a low-cost blood thinner that is used to treat or prevent blood clots in the veins, arteries, lungs, and heart. It is more popular than similar medications.
What is the safest blood thinner to take?
Newer pharmacological choices prevent blood clots in afib patients and offer alternatives to warfarin, which was formerly the cornerstone of treatment (Coumadin, Jantoven). Warfarin has a danger of causing brain bleeding, thus patients must be monitored frequently and follow a strict diet, which can be challenging. Warfarin interacts with vitamin K, which can be found in leafy greens and other foods.
Pradaxa (dabigatran), Xarelto (rivaroxaban), Eliquis (apixaban), and most recently Savaysa (edoxaban) are newer drugs that function by preventing blood from pooling in the heart from clotting. The newer medications, unlike warfarin, are safer and easier to use for patients.
“According to cardiologist John D. Day, MD, of Intermountain Medical Center Heart Institute in Murray, Utah, “several of these medicines have been demonstrated to offer even higher stroke prevention than warfarin.” Dr. Day went over the Heart Rhythm Society’s guidelines.
“Furthermore, all of the newer blood thinners reveal that the most feared bleeding danger, spontaneous bleeding in the brain, is significantly lower than with warfarin,” Day says, emphasizing the patient safety benefits.
What is the most prescribed blood thinner?
Anticoagulants of newer sorts are also available and are becoming more widespread. These are some of them:
Warfarin and its newer substitutes come in the form of pills or capsules. Heparin, an anticoagulant that can be injected, is another option. On the Electronic Medicines Compendium (EMC) website, you may learn more about heparin.
How much does diltiazem cost without insurance?
Diltiazem is a drug that is used to treat high blood pressure. It works by reducing the amount of effort your heart has to do by relaxing blood arteries. It’s part of a class of drugs known as calcium channel blockers. The lowest GoodRx price for diltiazem is roughly $9.12, which is 69 percent less than the average retail price of $29.57.
Is Jantoven generic for Coumadin?
Many patients are disappointed to find that Bristol Myers Squibb’s (BMS) brand of Coumadin would be phased out on June 1, 2020 in the United States, Canada, Latin America, and Saudi Arabia.
Some patients who had been using Coumadin for more than 30 years had to switch to generics. Many patients, however, have reported that generics caused major side effects and that they were unable to control their INR (a blood test that measures how long it takes your blood to clot) levels as effectively as previously.
It’s critical that you know who makes your warfarin so that your blood tests don’t get messed up. One approach to minimize confusion is to have your prescription refilled at the same pharmacy each time and to double-check the manufacturer’s name while picking up your medication.
With a certain form of irregular heart rhythm (atrial fibrillation), heart valve replacement, recent heart attack, and certain surgeries (such as hip/kneer replacement), warfarin is an anticoagulant also known as “bloodthinner,” a vitamin K antagonist to avoid life-threatening blood clots.
BMS Coumadin is no longer available in any of the world’s pharmacies. What has happened is that BMS has provided authorization to use the Coumadin name in several countries, but the medicine is manufactured by separate companies.
Coumadin is currently accessible from Australia, New Zealand, and Turkey.
Warfarin is only available in two commercial preparations in Australia and New Zealand: Coumadin and Marevan. Aspen Pharmacare Australia PtyLtd manufactures both products, which were originally manufactured by Boots Healthcare Australia Pty Ltd.
Coumadin and Marevan are no longer sponsored by Aspen Pharma in Australia, and distribution is now handled by Mylan Health. As a result, Mylan may appear on the label of Australian Coumadin in the future.
The active ingredient in Australian Coumadin is either 1 mg, 2 mg, or 5 mg of warfarin sodium.

Although the medicine bears the correct brand name and is medically comparable, it is not the same Coumadin manufactured by BMS and sold in the United States.
There have been other generic warfarin products approved, and you may have seen additional brands including Jantoven, Marevan, Lawarin, Waran, or Uniwarfin.
They contain the same active chemicals as Coumadin, so they will operate in the same way. However, there may be minor differences in their formulations, such as binders and colour, which could make your body to react differently.
Jantoven is a generic warfarin made in the United States by UPSHER-SMITH Laboratories. It is a trademark owned by UPSHER-SMITH. Jantoven is a generic form of warfarin, not a brand name like Coumadin.
Many patients have been taking Taro-warfarin for at least ten years because they trust Taro’s prescription accuracy and experience with this generic drug.
Warfarintablets are available from Taro Pharma in the same strengths as BMS’ Coumadin: 1 mg, 2 mg, 2.5 mg, 3 mg, 4 mg, 5 mg, 6 mg, 7.5 mg, 10 mg.

Is it possible to switch from Coumadin (Warfarin) to Eliquis or other direct oral anticoagulants?
Warfarin was the only option for patients who required to take an oral anticoagulant for roughly 50 years (blood thinner).
Because warfarin has a small therapeutic window that can be influenced by factors such as nutrition, individuals on the drug must have their INR tested on a frequent basis.
Your INR aim is usually between 2-3 and 2.53.5, but your healthcare practitioner will set your exact target.
New oral blood thinners that are just as effective as warfarin in preventing strokes in adults with atrial fibrillation and normal heart valves are now accessible. Directoral anticoagulants (DOACs) are drugs that function by blocking a clotting protein called Factor Xa, which is one of several clotting factors in our blood.
Apixaban (Eliquis) was the third direct oral anticoagulant to receive FDA clearance in the United States, following dabigatran (Pradaxa; Boehringer Ingelheim) in 2010 and rivaroxaban (Xarelto; Bayer/Janssen) in 2011. In 2015, Edoxaban (Savaysa; Daiichi Sankyo) entered the market.
DOACs have several advantages over warfarin, including the absence of regular blood tests, the absence of food restrictions, and the absence of pharmaceutical interactions.
- Some of the new drugs are not safe for people with significantly impaired renal function.
- When compared to missing a warfarin dose, missing just one dose puts you at a greater risk of stroke. This is due to the fact that DOACs are short-acting, whereas warfarin works for more than 24 hours. So, if you have difficulties keeping track of your meds or occasionally forget to take them, you should probably remain with warfarin.
- Eliquis and similar medications may not be effective in patients who have FACTOR V LEIDEN.
- Protein C is unable to cleave and degrade factor V as a result of this gene mutation, resulting in an increased susceptibility to produce blood clots. However, no randomized control trials involving Eliquis in particular hypercoagulable illnesses have been conducted.
In your instance, either generic warfarin or Eliquis may be a better alternative to Coumadin, but you should have a thorough discussion with your doctor and pharmacist before making any changes.
Eliquis, especially the brand-name version, can be quite costly. A less expensive, generic version of Eliquis could mean that individuals will be able to get the prescription more easily.
Since 2002, CIPA member pharmacies have had a spotless safety record, serving millions of American clients and selling drugs at up to 80% cheaper than in the United States.
Many CIPA member clients are referred directly by their healthcare practitioners, who have done their homework and are familiar with CIPA’s validity and safety measures.
However, low cost does not imply inferior quality! Our pharmacy partners’ products are strictly controlled and meet the requirements set forth by their local and national regulatory agencies.
What is the difference between warfarin and Coumadin?
The anticoagulant medicine warfarin sodium is used to prevent blood clotting. The terms “anti” and “coagulant” refer to substances that cause blood to clot. Warfarin regulates how your blood clots (thickens into a lump) within your blood vessels. Coumadin and Jantoven are two brand names for warfarin.
What do anticoagulants like warfarin do?
Anticoagulants assist your body control how quickly your blood clots, preventing unwanted clots from forming inside your arteries, veins, or heart during certain medical conditions or prolonged periods of inactivity.
If you develop a blood clot, an anticoagulant may prevent it from spreading. It may also keep a piece of the clot from breaking off and making its way to your lungs, brain, or heart. Anticoagulants also aid in the prevention of new clot formation.
The blood clot is not broken up by an anticoagulant. A clot, on the other hand, may dissolve on its own over time.
How do I take warfarin?
Every day, you’ll take warfarin. The dose is usually between 1 and 10 milligrams. Your healthcare practitioner will prescribe a dosage strength; however, this dosage may alter depending on the findings of each laboratory test.
- Take your dose if you forget to take it and remember within eight hours of the time it was scheduled to be taken. Wait until the next day and only take the prescribed dose for that day if it has been more than eight hours. DO NOT TAKE TWO DOSES AT ONCE.
- Call your healthcare practitioner if you forget to take your warfarin for two or more days in a row. It’s possible that the dose will need to be adjusted. (Never adjust your dose without first consulting your doctor.)
- To help you remember to take your prescription, obtain a pillbox or a calendar and check off each day after you take your dose.
- To avoid missing a dose, refill your medication one week before it expires.
- Take warfarin as directed by your doctor for as long as you need it. Never stop taking warfarin without first consulting your healthcare practitioner.
Warfarin is manufactured by a number of companies and comes in a variety of shapes, sizes, and colors. Each tablet hue corresponds to a different milligram strength (mg). For the various strengths of their tablets, all manufacturers use the same color code; however, the size and shape of the tablets may vary from one manufacturer to the next.
Each tablet is scored (has an indent across the tablet) and has the strength marked on one side so it can easily be broken in half if your healthcare professional adjusts your dose. For instance, if your doctor recommends a 5-mg pill and subsequently reduces your dose to 2.5 mg (21/2 mg), you should break one of the 5-mg tablets in half and take the half-tablet. Contact your provider if you have any queries regarding your warfarin dose.
What blood tests will I need while I am on warfarin?
To determine how well the drug is working, you will need to have your blood tested. The prothrombin time (PT or protime) blood test is used to calculate your International Normalized Ratio (INR) (INR). Your INR tells your doctor how well warfarin is working to prevent blood clots and whether or not the dose needs to be modified.
Blood tests can be performed in a laboratory, an anticoagulation clinic, a doctor’s office, or even at home. Blood tests are usually performed once or twice a week to once a month (if your results have been stable). Follow your doctor’s recommendations for how often you should have blood tests and when you should alter your warfarin dosage.
- INR levels can be affected by illness, health status, food, or prescription changes. Changes in your health, medications (prescription and over-the-counter), or lifestyle should be reported to your healthcare provider so that necessary dosage adjustments can be made.
- If you’re going on a trip, talk to your doctor about having your blood tests done at a different lab while you’re away.
Where should I store warfarin?
Warfarin should be kept at room temperature, away from extremes of temperature, heat, light, and moisture. Because of the wetness in bathrooms, never store drugs in bathroom cupboards.
What precautions should I take while taking warfarin?
It’s critical to avoid becoming pregnant when using warfarin. If you are a woman who has not yet entered menopause, use effective birth control to avoid pregnancy.
If you’re taking warfarin and thinking about getting pregnant, talk to your doctor about the dangers and how to minimize them. If you become pregnant or suspect you could be pregnant, call your doctor right away.
Inform all of your doctors and dentists that you are taking warfarin before having any treatment. Before having surgery or a dental operation, you may need to have a blood test and cease taking warfarin for a few days.
If feasible, contact your warfarin-monitoring healthcare professional at least two weeks before any dental or surgical operation. Do not discontinue taking warfarin without first consulting your physician.
Before beginning any workout or sports program, consult your doctor. If you plan to make any big dietary changes, such as a weight-loss regimen, or if you plan to take any nutritional supplements, talk to your doctor.
Vitamin K and foods Normal blood clotting requires vitamin K. Large variations in the amount of vitamin K in your diet, on the other hand, can affect how warfarin functions. If you eat vitamin K-rich foods, it’s critical to maintain a consistent weekly intake of vitamin K-rich foods.
If you’re thinking about changing your eating habits, let your doctor know. Tell your healthcare practitioner if you intend to:
Changing your eating habits could result in you getting more or less Vitamin K from your diet. Your provider may want to check your blood more frequently to see how warfarin is functioning if you change your eating patterns.
The following vegetables are known to have high vitamin K content per serving. While it’s vital to be aware of vitamin K-rich foods, it’s equally critical to maintain a well-balanced diet.
Choose vegetables that are low in Vitamin K, such as corn, squash, potatoes, onions, carrots, cucumbers, celery, peppers, pumpkin, and tomatoes, to get extra vegetable servings in your daily meal plan.
Teas made from herbs. Start avoiding the herbal teas and supplements listed below because they may impact the INR, making it too high or too low. If you want to consume tea, black tea (like orange pekoe tea) is fine because it is low in Vitamin K.
Supplements made from herbs. The INR may be affected by the herbal supplements listed below, causing it to be either high or too low. When celery, clove, garlic, ginger, and parsley are used in modest amounts in cooking or as a flavoring, they are usually harmless (these are marked by an asterisk .) They aren’t meant to be taken as a supplement.
- The herbal supplements listed below may prevent your blood from clotting and should not be used before surgery if you are on anticoagulant medications:
- Do not use any vitamin supplements that deliver more than 100% of the RDA (RDA). Tell your doctor if you’re taking any vitamins in excess of the RDA (especially vitamins A, C or E).
- Warfarin levels can also be affected by nutritional supplements like Boost and Ensure. Inquire with your doctor about the safety of using these products.
- The consumption of alcoholic beverages raises the risk of severe bleeding. If you’re taking warfarin, check with your doctor to see if drinking alcoholic beverages is safe for you.
Some drugs can make warfarin’s anticoagulant action stronger, while others can make it less. When you quit, start, or raise the amount of drugs that are known to influence the way warfarin works, you may require further blood tests. It’s possible that the warfarin dosage will need to be altered as well. If you experience any changes in your other prescription prescriptions, talk to your healthcare professional who handles your warfarin.
This is not an exhaustive list of drugs that potentially interfere with warfarin’s effectiveness. Many non-prescription drugs, in fact, can interfere with the effectiveness of warfarin. Acetaminophen (Tylenol), aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) (such as ibuprofen, naproxen, or ketoprofen, and cold and cough treatments containing NSAIDs), antacids, laxatives, or other pain or discomfort medications are among examples.
Before using any over-the-counter drug, herbal product, natural treatment, nutritional supplement, or prescription medication from another healthcare practitioner or dentist, always check with the healthcare provider who monitors your warfarin. Your doctor may need to alter your warfarin dosage or suggest a different drug or product that is less likely to interact with warfarin. Stopping or starting any medications without first consulting your healthcare professional is not a good idea.
- When using razors, be cautious. To reduce the risk of cuts, use an electric razor or hair-removing lotions.
- Brush your teeth with a gentle toothbrush. Brush and floss your teeth gently to avoid gum bleeding.
- In the event of an emergency, keep your healthcare provider’s phone number on hand.
- If you experience any symptoms of disease, such as vomiting, diarrhea, infection, or fever, contact your healthcare professional. Warfarin’s effectiveness can be affected by illness.
- Always keep or wear identification that says you’re on warfarin. You may not be able to speak for yourself in an emergency.
- Avoid potentially dangerous situations at home or at work. Because warfarin inhibits clotting, even minor injuries must be monitored for bleeding. When you’re on warfarin, bruising (bleeding beneath the skin) and wounds from sharp objects are more dangerous. If you’ve suffered any injuries to your body or head as a result of falls or strikes, see your doctor right once.
- Before you travel, see your doctor. Before you travel, you may require a blood test and a dose adjustment for your warfarin.
- Carry your prescriptions with you at all times while traveling. Do not pack prescription pills in checked baggage or leave them in the car.
- If you’re going to be sat for a long time throughout your trip, get up and walk if you can, or do some foot and leg raises.
What should I do if I cut myself while on warfarin?
If you cut yourself and it’s a little cut, apply steady pressure to the wound until it stops bleeding. It could take up to ten minutes. Continue to apply pressure and proceed to the nearest emergency room if the bleeding does not stop.
If you cut yourself and it’s a large cut, apply consistent pressure and get medical attention right once, either by dialing 911 or your local emergency number, or by having someone drive you to the nearest emergency room.
What are the side effects of warfarin?
The most common side effect of warfarin is bleeding, which can manifest as a variety of symptoms. If you see any of the following signs of bleeding, call your doctor:
- Feeling colder, weaker, or exhausted than normal, or seeming paler than usual (symptoms of anemia).
- Bruises that arise out of nowhere, swell up, and hurt; purplish blotches on your skin.
If you have any of these symptoms, your doctor may recommend a blood test, a dose adjustment, drug discontinuation, or anti-bleeding medication.
Summary of important points to remember
- Many drugs can interact with warfarin, so talk to your doctor and pharmacist about everything you’re taking, including over-the-counter medications.
- Do not quit or begin taking any drugs, herbal items, natural cures, or nutritional supplements without first consulting your warfarin medication provider.
- Consume roughly the same quantity of vitamin K-rich meals on a weekly basis, as these foods can impact how warfarin functions.
- DO NOT take a duplicate dose if you forget to take a pill. On the same day, take the missed dose as soon as feasible. To make up for the missing dose, DO NOT take a double dose of warfarin the next day.
- Keep an eye out for signs of unusual or excessive bleeding or bruising. If you suspect something is wrong, contact your healthcare practitioner straight once.
- DO NOT switch warfarin products without consulting your doctor first. Different brands of warfarin medications may not be comparable, and if you switch brands, your dose may need to be checked and changed more regularly.
- DO NOT STOP taking warfarin for any reason, even if it’s for a simple surgery like dental work, without first seeing your doctor who oversees your treatment.
- Alcohol can make you more prone to bleeding. If you’re taking warfarin, check with your doctor to see if drinking alcoholic beverages is safe for you.
Is Coumadin really rat poison?
Studies reveal that the toxins accumulate in birds of prey and other species, prompting legislation in Canada and the United States to prohibit the use of rodent poisons based on blood thinners.
Anticoagulant rodenticides (ARs) are compounds that function similarly to the blood-thinning medicine warfarin in humans. Warfarin is employed as a rat poison, although it is a first-generation AR, meaning it is less deadly and less prone to bioaccumulation than its second-generation counterparts.
Pesticides like DDT have long been known to build up in, and occasionally kill, animals that feast on target pests, but scientists didn’t realize how much this might also happen with second-generation ARs until recently. “It appears that whenever someone obtains a group of deceased birds of prey and looks at their livers, they discover a remarkably high prevalence of these substances,” says John Elliott, an ecotoxicologist at Environment Canada in Delta.
Elliot announced this week at the 2012 meeting of the North American division of the Society of Environmental Toxicology and Chemistry in Long Beach, California, that in a study of more than 130 dead birds of prey found in and around Vancouver, Canada, “virtually 100 percent” of the owls and a large proportion of the hawks had residues of at least one second-generation AR in their livers.
“From a regulatory standpoint, it’s ‘PBT,'” he explains. “Bioaccumulative, persistent, and poisonous.”
These birds of prey are most likely eating poisoned rats. Other birds, on the other hand, can be poisoned if insects consume the rat bait and subsequently eat the insects. Some birds will eat the bait right off the hook. Elliott put sparrows in a cage with rat-bait pellets in a test. He explains, “They went right for the bait.”
ARs function by disrupting the capacity of blood to clot. According to Maureen Murray, a wildlife veterinarian at Tufts Cummings School of Veterinary Medicine in North Grafton, Massachusetts, who has worked with hundreds of injured birds of prey, many of whom are suffering from AR poisoning, there is a huge variation in how susceptible individual birds and animals are to the poisons. Humans who use blood-thinning medicines like warfarin have similar variations. “It’s a drug that necessitates a lot of monitoring,” Murray explains.
Governments are taking action to address the issue. According to Elliott, Canada will begin restricting most outdoor residential usage of ARs on January 1st to the less harmful first-generation compounds. In most cases, bait will have to be kept in tamper-resistant bait stations or other areas where non-target species cannot reach it.
Second-generation ARs may be banned from the consumer market by the US Environmental Protection Agency. According to Anne Fairbrother, director of ecosciences at Exponent, a science and engineering firm in Bellevue, Washington, there is also a trend toward higher use of bromethalin, a strong neurotoxic.
She believes, however, that residential bans will have little impact because most outdoor rodenticide use is done by professional pest-control operators. According to a survey done last summer, “a lot” of operators keep their products outside for long periods of time. “Wildlife exposures will be greatly increased,” adds Fairbrother.
She’s also not keen about the prospect of moving to bromethalin. “There is no antidote,” she continues, implying that the substance could be harmful to children and pets. Vitamin K, on the other hand, can be used to alleviate AR toxicity.
Fairbrother suggests that a better solution would be to prohibit permanent bait stations and require pest-control professionals to use ARs only when needed. Consumers should also be informed about the substances’ potential environmental consequences.
“We know customers can understand and respond to wildlife exposure alerts,” Fairbrother says. A survey a few years ago questioned customers if they were aware that rodenticides can harm non-target species, she says. She claims, “They had no idea.” “Now that I know, I’m going to be a lot more careful about how I use them,” they said after being notified.
