How often should your doctor track digoxin levels?

I have been on digoxin for several years to treat my chronic SVT. My doctor has only checked my levels once, but I recently read somewhere that doctors should check every few months. If my SVT is controlled is it okay to only check once every year or two?

    Tough question! Digoxin is a quirky drug. It has a very tight blood level of effectiveness between not working at all and being toxic. Additionally, blood levels can be affected by other drugs and conditions. For example, calcium levels and thyroid function can greatly affect the required dose of digoxin.

    I am afraid only your doctor can answer this question. Your doc is the only one who knows you well enough. However, the fact that your SVT is controlled is a good sign!

    Thank you! I do have Graves' Disease and currently take A LOT of medications! I will ask my doctor the next time I see him, and I do trust his judgement!

    Interesting, I have thyroid issues and SVT too. I wonder if there is a connection or just a coincidence?

    There is definitely a connection! If you are hyperthyroid or even hypothyroid and either overdose your meds or get a temporary spike in thyroid activity you can trigger an episode (or several) of SVT. Here is a useful article on the subject.
