What's this test for?

This test is ideal if you're taking disopyramide to manage an irregular heartbeat or fast heart rhythm and need to make sure your dose is working correctly. It measures how much of the medication is in your blood, which helps confirm you're getting enough to control your heart rhythm without taking too much. It's especially useful if you've had a recent dose change or are experiencing side effects.

What happens after I get my results?

Your results will show up in your account with the normal therapeutic range explained so you can see exactly where your level falls. If your level is too low or too high, simple next steps like adjusting timing of your next dose or retesting sooner can help, and if your result suggests a dangerously high level with symptoms like dizziness or fainting, seek medical care right away. You can download a standard lab report from your account at any time, and the trends feature lets you track your disopyramide levels over multiple tests to see how they change.

Who should consider this test?

Anyone currently prescribed disopyramide for an irregular heartbeat or rapid heart rate should consider this test, especially after starting the medication or changing the dose. It's also useful if you have kidney or liver issues, since these can affect how your body processes the drug. People experiencing possible side effects like blurred vision, dry mouth, or dizziness may also want to check their levels.

What symptoms indicate I may need this test?

If you notice your heart racing, skipping beats, or fluttering again after starting disopyramide, it could mean your dose needs checking. Symptoms like dizziness, blurred vision, very dry mouth, or fainting can signal your level is too high and needs attention. Feeling unusually tired or noticing your original heart rhythm symptoms return can also be a sign your level is too low.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. Once processed, they'll be uploaded directly to your secure online account where you can view and download them.

What is disopyramide and why does it matter?

Disopyramide is a medication used to control irregular or fast heartbeats by helping stabilize the heart's electrical activity. Getting the dose right matters a lot because too little won't control your heart rhythm, while too much can cause serious side effects. Regular level checks help keep the medication working safely and effectively for you.

What does high disopyramide level mean?

A high level means there's more of the drug in your blood than needed, which raises the risk of side effects like very low blood pressure, dizziness, blurred vision, or dangerous heart rhythm changes. This can happen if your kidneys or liver aren't clearing the drug as quickly as usual, or if the dose is too high for your body. If you have symptoms like fainting or severe dizziness along with a high result, seek medical care immediately.

What does low disopyramide level mean?

A low level means there may not be enough medication in your system to properly control your heart rhythm, which could let your original symptoms like a racing or irregular heartbeat come back. This can happen if a dose was missed, taken inconsistently, or if your body processes the drug faster than average. Retesting after confirming consistent dosing can help clarify whether an adjustment is needed.

How often should I retest?

Retesting is often recommended after any dose change, typically once the medication has reached a steady level in your body, which is usually a few days. Beyond that, periodic checks every few months or whenever new symptoms appear can help make sure your levels stay in the right range. Your exact retest schedule may depend on your overall health and how stable your levels have been.

What should I do if my results are abnormal?

If your level is outside the normal range, avoid changing your dose on your own and instead review the report details in your account for guidance on what the number means. Keep track of any symptoms you're experiencing and note the timing of your last dose relative to the blood draw, since this affects results. If you have severe symptoms like fainting, chest pain, or a very irregular heartbeat, seek medical care right away.
