What Is IV Lasix?

Lasix is a diuretic medication that is used to treat patients with “excessive fluid accumulation”. Intravenous (IV) Lasix is typically recommended when other methods of treatment have failed.

When Might I Need IV Lasix?

Your doctor may recommend IV Lasix as a treatment for relapsing heart failure, hypertension, or other issues that may be causing your body to hold on to fluid and salt. Excessive fluid and salt in the body can make it hard for your heart to function efficiently.

What Should I Expect?

When taking Lasix intravenously, a medical staff member will check your blood pressure and may even draw blood. Next, the Lasix will be administered through an IV. Your blood pressure will be monitored throughout the visit and again when the appointment is over.

Each IV dose will typically be effective for 4-6 hours.

There are some side effects associated with IV Lasix, including:

  • Dizziness
  • Cramps
  • Weakness/Faintness
  • Cottonmouth
  • Diarrhea
  • Temporary Hearing Issues

If you experience more severe side effects like excessive weight loss or dehydration, please contact your doctor immediately.

How Should I Prepare?

Before having Lasix administered intravenously, it is important that you discuss any medical conditions you have or medications you are taking with your doctor. If you are or may be pregnant, please inform your doctor beforehand.

In addition to IV Lasix treatment, your doctor will be able to give you detailed information on dietary or lifestyle changes you can make for effective management of your health issues.

If you have any questions about IV Lasix, please ask your doctor during your next visit.
