Monitoring Anticoagulation at Home

Monitoring Anticoagulation at Home

Are there any options for do-it-yourself monitoring?

While most people on warfarin or Coumadin® go to an anticoagulation clinic to monitor and test their blood’s clotting time, some people are able to do their own testing and monitoring from home. People who do so may feel a greater sense of control and ability to take part in managing their own care. This option is especially valuable for people who maintain a full schedule, enjoy traveling, or have other reasons that make it difficult to get to the clinic. The need for testing and monitoring at home only applies to people taking warfarin or Coumadin® for stroke risk reduction using anticoagulation medication; NOACs do not require testing.

Who is a good candidate for at-home anticoagulation monitoring?

If you have been diagnosed with atrial fibrillation and have been taking warfarin or Coumadin® for at least 90 days, you may be eligible to begin testing your INR or clotting time (also called Prothrombin time) from home. If you’re interested and willing to manage your part of the process, your healthcare provider can submit a request to authorize you to complete your testing and monitoring requirements from home. From there, you’ll work with your insurance provider or national healthcare benefits program to arrange for any necessary payments and connect you with a monitoring company that will provide the equipment and teach you the steps for timely and accurate measurement.

What is the process for at-home monitoring?

Most medical coverage options allow for weekly or bi-weekly testing, and the testing must usually be communicated back to the monitoring company who then communicates it to your doctor so that you can maintain a prescription for your medication. The monitoring company will alert your healthcare provider if results of your blood clotting time are out-of-range so your doctor can promptly adjust your dosage. This regular communication also allows the monitoring company to track your usage and send additional supplies when your usage data indicates you should be running low, which will save you time and energy.

People who monitor at home will likely want to create a convenient place for storing supplies, testing, and reporting results. During training, your monitoring company may help you work out a system to remind yourself when it’s time to test.

Just wondering if anyone has had an issue with a low pulse with Atenolol. I’ve been dealing with a fib for two years and over the last two months it’s gotten to the point where it’s almost every other day lasting  around five or six hours each time. I tried metoprolol and cardizem but it just made me too sick with all the side effects. I want to go back to the atenolol but I’m concerned with my pulse getting in the 40s when I’m taking it.

This may have been asked before, I'm wondering if anyone has had the convergence procedure done. I've never heard of it & wondered if it's a viable alternative to other procedures, the good & the bad, and success rates. Here's an article about it, I hope it's ok to post.

I'm 29 and have had a few episodes in the past, but this one has lasted so I went to the urgent care, which led me to the er. They said I have afib going on, an irregularly irregular heart beat, but my pulse and blood pressure were normal, just skipping beats and lightheaded.

Went to the cardiologist and he talked for a few minutes and went straight to electric cardioversion for the following tuesday, it's friday when he said it's almost Monday and I'm gonna try to get a 2nd opinion.

Honestly being thus young and I'm pretty healthy, I'm getting very anxious and depressed.
