When should you consider stopping your weight loss medication?

You might think the only time to stop taking WLIs is after you’ve reached your goal weight, but there may be other reasons why you might consider stopping.

You have achieved your goal weight

Once you’ve reached your target weight and have maintained it for a few months, you can discuss with your doctor how to taper off the treatment.

Each person will reach their target weight at a different time; for some, it may take up to a year, while for others, it may take even longer. While some insurance providers or medical guidelines may have suggestions regarding the duration of weight loss injections, other health experts claim continuing to take them can help sustain weight loss and preserve health benefits.

So there isn’t any specific timeframe on when everyone should stop; only you and your doctor can discuss this after reaching your target weight.

You’re having problematic side effects

It’s very common to get side effects when you start taking WLI. The most common side effects typically include nausea, vomiting, stomach issues and fatigue. As your body adjusts to the treatment, these side effects should subside. But after each dose increase, you may notice these side effects may worsen again temporarily.

Your healthcare provider will do their best to minimize the risk of side effects. They'll gradually increase your dose, provide tips to manage them, and avoid increasing the dosage until you’re ready.

But if the side effects persist or become severe, you may be advised to discontinue treatment for your overall health. You might be able to try an alternative weight loss medication, likely one that isn’t a GLP-1 – and your provider will be able to advise you on this.

The long-term cost is too much

Weight loss injections can be expensive. In the US, the cost of Wegovy can vary depending on insurance coverage, but the list price for a year’s supply can exceed $16,000. Zepbound costs over time can sometimes work out a little lower, but the list price may still reach $13,000 annually.

If you haven’t yet started WLI, try to financially plan for at least 1.5 years of treatment. This duration should provide you with enough time to achieve a significant amount of weight loss – approximately 8.3% mean weight loss achieved with Wegovy and 15.3% with Zepbound by month 12.

Additionally, this timeline will allow you to taper off the medication gradually, which can help prevent side effects and reduce the risk of regaining weight.

The medication isn't effective as it was

WLI can be effective for helping you lose weight. In the first few months, you should notice significant weight loss, but after a year or two, your progress might plateau.

This plateau usually happens for several reasons, including your body adapting to the medication, so it doesn’t have the same effects as it did initially.

Additionally, factors such as your diet and physical activity levels can contribute to this plateau. If you’ve stopped maintaining a calorie deficit or have been less active, you might not see as much of a difference in your weight loss progress.

You feel ‘ready’

If you’re satisfied with your weight loss and feel confident in your ability to maintain the results without further treatment, it might be time to stop your treatment. To help you decide if you’re ready, you might find it helpful to ask yourself:

  • Are you happy with your weight loss results?
  • Are you confident you can sustain this weight loss?
  • Are you physically active a few times a week?
  • Are you following a well-balanced, calorie-controlled diet?

If you answered ‘yes’ to all of these questions, it could be a good time to come off treatment.

How to come off weight loss injections

Your doctor will provide all the information on how to stop weight loss injections, but here’s what the process may look like:

Recommended tapering methods

The recommended way to discontinue GLP-1 treatment is to gradually decrease your dose. This will help minimize side effects, and give your body time to adjust to the reduced dose. This will allow you to solidify your healthy habits, like diet and exercise. Tapering off will also help prevent rapid weight gain, which is a challenge for many people after stopping treatment.

The tapering method will differ for each person. Generally, you’ll reduce the dose every few weeks, so it could take approximately four to five months to completely stop.

Is it safe to stop weight loss injections suddenly?

Unless you’ve been advised to by a healthcare provider for medical reasons (such as a drug interaction or side effects), then it generally isn’t recommended to stop using GLP-1 treatment suddenly. Doing so can lead to a big increase in appetite, which significantly increases your risk of weight regain.

GLP-1s promote a feeling of fullness, slow stomach emptying, and decrease appetite. Discontinuing them abruptly can lead to overeating. Many individuals might gain weight after stopping treatment, and stopping suddenly only increases this risk.

Stopping suddenly can also interfere with glucose metabolism and cause high blood sugar levels. This can lead to fatigue, blurred vision, and feeling excessively thirsty.

How to maximise your long-term success when stopping weight loss injections

Here are some tips on how to prevent weight regain after stopping treatment.

Lifestyle consolidation

Critically review your diet and exercise habits. If you have behaviors that cause you to overeat, try to change them. For example, if you tend to have a late-night snack, sleep earlier, or if you order out when there’s nothing to eat, consider meal prepping in advance.

Be strict with yourself. You should generally eat healthily and work out at least three times a week. But also allowing yourself cheat days can help you have a more sustainable lifestyle.

Remind yourself of the bigger picture. Think about why you started this weight loss treatment and how regaining weight will undermine the goal you set for yourself months or years ago.

Create a good support network. Allow support from your friends, family, registered dietitians, doctors, and online communities to help keep you on track.

Lastly, be nice to yourself. If you have a bad day of eating or didn’t work out like you hoped, try not to worry too much about it. So long as it doesn’t become part of your regular habits, a couple of bad days shouldn’t affect the progress you’ve been making for several years.

Want to stop weight loss treatment for another reason?

If you want to stop using weight loss injections or are unsure when to stop, contact your doctor, and they’ll answer any concerns you may have.
