Can You Go Off and On GLP-1 Weight Loss Drugs?

Whether to save money or reduce side effects, there are many reasons people are curious about cycling off and on glucagon-like peptide-1 (GLP-1) weight loss drugs like semaglutide (Ozempic, Wegovy). Others may be forced to stop and restart due to loss of access, pregnancy, or an upcoming medical procedure.

Though there are some legitimate and unavoidable reasons to pause your GLP-1 use, experts generally recommend staying on them for the foreseeable future to maintain weight loss and continue enjoying the associated health benefits. Most people who stop using their GLP-1 drug gain back the weight they’ve lost, and frequently yo-yoing between weight loss and weight gain may have some negative effects on your long-term health.

GLP-1 cycling can negatively impact weight loss efforts by leading to weight yo-yoing.

“If the intervals between shots are long enough, this can cause some weight regain, which can be very frustrating for patients,” says Meghan Garcia-Webb, MD, a board-certified internal, lifestyle, and obesity medicine physician in private practice in Wellesley, Massachusetts. When repeated over time, losing and regaining weight can also carry metabolic and psychological consequences.

“In general, repeated cycles of weight loss and regain is associated with worsened cardiometabolic risk factors,” says Sara Velayati, MD, obesity medicine specialist and assistant professor at Albert Einstein College of Medicine in New York City.

“In general, when someone goes off a GLP-1, it stops working,” says Dr. Garcia-Webb. Any of the effects you experienced while taking the medication go away: Food noise and increased appetite return, and weight regain often follows.

How quickly that process begins depends, in part, on the medication you’re taking and how long it stays in your system. “Wegovy and Zepbound [tirzepatide] will be out of a person’s system in a few weeks, while Saxenda [liraglutide], because it’s a daily medication, will be out in a few days,” says Garcia-Webb.

Skipping GLP-1 doses generally isn’t a good idea, says Garcia-Webb. However, there are legitimate medical reasons to take a planned break from GLP-1s.

For instance, people who have an upcoming medical procedure, such as a colonoscopy or surgery, must pause GLP-1 use. “It’s extremely important to stop these medications well ahead of time to lower your risk of aspiration (breathing in stomach contents) during surgery, as this can be very dangerous,” says Garcia-Webb. Ask your doctor when you should stop and restart your GLP-1.

“Pregnancy is also a good reason to stop taking a GLP-1 medication,” says Garcia-Webb. She suggests stopping GLP-1s two to three months before trying to get pregnant.

There are also nonmedical factors that may require you to take an unwanted GLP-1 break. “Many people have to deal with going on and off medications due to insurance issues, supply chain issues, or the changing cost of medications,” says Garcia-Webb. Pausing your medication for more than a few weeks may require going back to a starter dose and restarting the long process of working up to a full-strength dosage.

It’s possible to use a GLP-1 medication temporarily if you have a specific reason, such as needing to lose a set amount of weight to prepare for a weight loss procedure, says Velayati.

However, beyond such specific, time-limited scenarios, both clinical evidence and guidelines state that GLP-1 drugs should not be used in the short term if your goal is lasting weight loss and health risk reduction.

“Patients should understand that these medications are generally intended for long-term management of a chronic condition,” says Velayati.

The easiest and safest way to keep the weight off is to continue taking your GLP-1 medication as prescribed.

Once you lose your desired amount of weight with a GLP-1 drug, it’s also important to use healthy lifestyle habits to help maintain your weight loss.

Eating a nutritious diet that incorporates at least 25 grams of fiber per day to keep you satiated is essential.

If you’re eager to reduce your use of your GLP-1, talk to your doctor about your options. Some clinicians may be willing to experiment with lowering your dose to find a “maintenance dose,” though this practice has not been validated by clinical research and isn’t approved by the U.S. Food and Drug Administration.

“The maintenance dose is the highest dose that keeps a patient at their healthy weight but doesn’t cause intolerable side effects,” says Garcia-Webb. Only change your dosage in close partnership with your doctor, and know that there’s no guarantee that you’ll have success with a smaller dose, even after some trial and error.

• Experts generally recommend long-term GLP-1 use, because stopping these weight loss medications typically leads to increased appetite and weight regain.
• Repeatedly stopping and restarting GLP-1 drugs can cause weight yo-yoing, which increases your risk for cardiometabolic dysfunction and negatively shifts body composition toward a higher body fat percentage.
• While consistent GLP-1 use is ideal, medical professionals note that some people may need to stop taking these drugs temporarily for surgery to prevent aspiration, during pregnancy, or to manage intolerable gastrointestinal side effects like nausea and vomiting.
• To sustain weight loss achieved with a GLP-1 medication, it’s essential that you maintain a healthy diet and consistent exercise routine.
