Key takeaways
Furosemide (Lasix) and amiodarone (Pacerone) are both prescription medications, but they serve very different purposes. Furosemide (Lasix) is a diuretic, also known as a water pill, that helps you get rid of extra fluid and lower blood pressure by making you urinate more. It's often used for swelling due to heart, liver, or kidney problems. On the other hand, amiodarone (Pacerone) is an antiarrhythmic medication used to treat serious heart rhythm problems. It works by slowing down the electrical activity in your heart to keep your heartbeat normal. Furosemide (Lasix) starts working within an hour and is taken once or twice daily, while amiodarone (Pacerone) can take weeks to show effects and often requires a hospital stay to start. Furosemide (Lasix) can cause dehydration and electrolyte imbalances, whereas amiodarone (Pacerone) has a range of serious side effects, including lung and liver damage, and can stay in your body for weeks. Both medications are available in generic forms and require careful monitoring by your healthcare provider.
