What You Can Do To Help

Taking MULTAQ as part of your overall atrial fibrillation (AFib) treatment plan can make a critical difference in your health. But there are things you can do to help control your AFib. Alcohol, caffeine, smoking, and stress can play a role in triggering AFib episodes. Avoiding these may help.

There are also other medical conditions which can put you at risk for developing AFib or making your AFib worse.

Managing these conditions may help with your AFib.

High blood pressure. 49.3% of people with AFib also have high blood pressure. Because high blood pressure can put you at risk for developing AFib, working with your doctor to manage your high blood pressure may help decrease this risk.
Diabetes. 17.1% of people with AFib also have diabetes. Diabetes can put you at risk for developing AFib. Working with your doctor to help manage your diabetes may help decrease this risk.
Obesity. Obesity also increases the risk of developing AFib. Getting regular exercise and eating better may make a difference. Talk to your doctor before starting any diet or exercise routine.

Make sure to talk with your doctor before making any changes to your diet or exercise routine.

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.
