Anti-obesity medications, including GLP-1 receptor agonists, have reshaped weight management, but continuity of therapy isn’t always realistic. Cost barriers, insurance changes, and tolerability issues often lead patients to pause treatment. Months later, many return after experiencing weight regain, asking to restart therapy.
These conversations can be complex. When is it appropriate to reinitiate treatment? Should clinicians restart the same agent or consider switching? And how should expectations be reframed after an interruption? With limited formal guidance on reintroduction strategies, clinicians are often left to rely on their own judgment and the patient's opinion.
On Healthcasts, providers weighed in on how they approach restarting anti-obesity medications after a break, offering practical insight into timing, agent selection, and patient counseling.

Key takeaways about restarting GLP-1 therapy:
Family Practice
"1. When a patient feels they are unable to do without it—weight is climbing, and hunger has returned and is preoccupying, and the patient is challenged (and not succeeding) to avoid temptation.
2. If an agent has been successful, there is no reason it wouldn't continue to be successful. Maintenance dosing and clear-eyed future weaning planning should be a big part of the next regimen, however. I would start a patient back on what they'd been successful on previously, but sometimes GLP-1s of a different manufacturer may be preferred by the patient due to cost, and to that we need to be sensitive."
Family Practice
"1. It depends on why it was stopped, if due to side effects or cost, I think it is fine to restart; however, MEAL PLANNING and adherence are mandatory for me, there is way too much I want a med for weight loss and not change my life, which is what got them into obesity in the first place. If they stopped it because they 'fell off the wagon,' it depends on whether this is the first time or a pattern. If it's a pattern, then I am not so inclined to restart meds.
2. If they had side effects or issues with a med, then no, I do not restart. If they quit due to cost or other reasons, I think it is okay to go back to the same agent if they saw success with it."
Nurse Practitioner
"1. I would restart if weight gain recurs after stopping, or other co-morbidities worsen secondary to weight gain.
2. If the previous agent worked, I would try that one again, but I am open to switching."
Unspecified/Other
"1. Restart whenever the patient is ready.
2. For me, typically depends on coverage/affordability, always assuming the agent is not contraindicated, and if the patient meets criteria."
Family Practice
"1. As long as the patient understands that permanent therapy with GLP-1 will be necessary to maintain weight loss, you can resume medication anytime. Starting over again at a low dose and titrating up will likely be needed.
2. Insurance will usually make the decision for you, but if there actually are options, let past success or failure dictate the specific med."
Family Practice
"1. As soon as the patient is ready, preferably before gaining a bunch of weight back. It's easier to do microdosing and keep the weight off than to try to start over and lose weight again.
2. Depends on the patient. If it worked well before, I'd use the same agent. If there were side effects or a lack of benefit, then I'd switch agents."
Nurse Practitioner
"1. We usually try to help patients take a 3-month break.
2. You can do either; it does depend on patient results and tolerance/affordability."
Nurse Practitioner
"1. Greater than 10% regain of baseline weight.
2. I would retry the same agent if the patient had great success with it in the past, and had no insurance issues. If there are problems with success or coverage, it is definitely time to try a new agent. There are many on the market to choose from."
Family Practice
"1. I've read somewhere that patients can regain up to about 14 to 18% of the weight that they lost once they come off these medications, and that can be even more if they have not made lifestyle changes. Restarting could be anytime the patient is motivated to get back on it, but actually add on the lifestyle changes that are necessary to maintain the weight off.
2. If the patient tolerated the medication and has results, I would use the same medication; otherwise switched to a different one."
Family Practice
"1. I would suggest 2-4 weeks, but this is case dependent, based on shared decision making with the patient.
2. Once again, case by case, depending on experience, along with shared decision making, either choice is an option under different circumstances."
