What Happens When You Stop Taking Lasix?

Lasix is a medication that helps prevent fluid buildup in the body. This can help to reduce swelling, as well as improve blood circulation. Sometimes,


Lasix may also be used to help treat high blood pressure, weak pulse, or orthostatic hypotension. 

Mild Symptoms

What happens when you stop taking furosemide within a short period?

Some side effects may require medical attention if you have been taking Lasix for an extended period and stop taking it suddenly. Withdrawal symptoms such as nausea, vomiting, headache, increased thirst, electrolyte imbalance, and urination may occur when you stop taking this drug.

Also, stopping Lasix makes your kidneys return to their original function, which will cause fluids to build up again.

The buildup of fluids can lead to medical conditions like shortness of breath, swelling around the feet and ankles, and increased urination at night, especially for elderly patients.

Severe Symptoms

In more severe cases, what happens when you quit taking Lasix?

Well, your body may not have enough Lasix to function correctly. Your kidneys will try to compensate by producing more renin, an enzyme that regulates blood pressure.


Moreover, your systolic blood pressure may shoot up, causing congestive heart failure and stroke, especially for patients with a heart failure history. A faster heart rate can also lead to potential cardiac risks like a heart attack or damage to blood vessels.

Therefore, talk to your doctor about how to stop taking Lasix safely to avoid any medical emergency or if you have a medical history of cardiac issues.

Things to Remember After Stopping Lasix

First, speak with your doctor about stopping the medication’s risks and benefits.

Keep an Eye on Dehydration

Once your doctor approves and you stop taking Lasix, your body no longer has the same water access level. This can lead to dehydration. This sudden drop in fluid levels can cause several health problems.

After stopping Lasix, drinking lots of fluids is essential so that you don’t get dehydrated and drink enough water to avoid developing symptoms like dizziness, fatigue, and headaches.

The Sodium Level in the Body

It’s also a good idea to have some salty snacks on hand if you feel hungry. Some people experience cravings for high-sodium foods like french fries or chips to keep their sodium levels in control.

Eat these foods sparingly because they are often fried in saturated oils, which may contribute to sudden weight gain and heart disease.

Instead, choose healthy snacks such as yogurt with fruit, whole grain crackers with cheese, fruit smoothies made with almond milk and frozen berries, apple slices dipped in peanut butter, and celery sticks dipped in hummus.

If you experience any symptoms after discontinuing Lasix, consult a licensed healthcare professional in your nearest emergency room as soon as possible.

Should You Take the Risk of Staying on Lasix Medication?

What is Lasix?

Lasix, also known as furosemide, is a prescription drug typically used to treat fluid buildup in the lungs, the stomach, or the legs caused by congestive heart failure, liver disease, or kidney failure.
