What you should know about MULTAQ

Take MULTAQ exactly as prescribed. And remember—it's important to keep talking to your doctor about MULTAQ, and to ask any questions that come up.

Make MULTAQ a part of your daily routine.

The recommended dose is 1 tablet, 2 times a day with food—take 1 tablet at breakfast, and the other with your evening meal.

Please note, drinking grapefruit juice may change how your body absorbs MULTAQ. So you shouldn't drink grapefruit juice while you're taking MULTAQ.

If you forget to take MULTAQ, wait and take your next dose at your regular time.

Don't try to "double up" to make up for a missed dose. If you're having trouble remembering to take MULTAQ as prescribed, be sure to speak with your doctor.

Here are a few simple things you can do to help you remember to take MULTAQ:

Keep your pills in an easy-to-see spot in the room where you eat most of your meals
Set an alarm clock or the alarm on your watch to remind you to take MULTAQ at the same time each day
Buy a pillbox labeled with the 7 days of the week, and place the prescribed amount of MULTAQ into each day's compartment

MULTAQ can interact with certain medications.

This can cause serious side effects. It's important to tell your doctor and pharmacist about any other medicines, including herbal supplements, that you are taking. For a list of what you should not take while on MULTAQ, read the Important Safety Information.

Some people may experience diarrhea, nausea, vomiting, pain in the stomach area, and indigestion when they begin taking MULTAQ. For more information and a complete list of side effects, please read the MULTAQ Medication Guide.

Episodes may come and go, but the disease doesn't go away.

After starting on MULTAQ, you may find that you're experiencing fewer AFib episodes. But even if you've been better for a long time, this doesn't mean that you no longer have AFib. You should keep taking MULTAQ as prescribed.

You may still have episodes even while taking MULTAQ.

This doesn't mean that MULTAQ isn't working. When you're taking MULTAQ, you can go more days without having an AFib episode, as well as reduce your risk of going to the hospital for heart problems. However, AFib is a chronic disease and can't be cured. Consult with your doctor if you experience symptoms that concern you.

MULTAQ is a prescription medicine used to lower the chance you would need to go into the hospital for heart problems. It is meant for people who have had an abnormal heart rhythm called atrial fibrillation (AFib) or atrial flutter (AFlutter) in the last 6 months, but who may currently have a regular heart rhythm or will have medical treatment to return to a regular rhythm. MULTAQ may be safely used by people who have had AFib and AFlutter who also have other conditions such as high blood pressure, stroke, or diabetes.
