Key takeaways:
Seroquel (quetiapine) is an atypical antipsychotic that can treat various mental health conditions. Weight gain is a common side effect of Seroquel.
In clinical trials, people taking Seroquel for about 6 months gained an average of 4 lbs. But nearly 1 in 4 people gained 7% or more of their starting body weight.
Certain lifestyle changes, such as a nutritious diet, regular exercise, and limited alcohol consumption, can help manage weight gain with Seroquel. Healthcare providers may also suggest weight loss medications for certain people.
Seroquel (quetiapine) is an atypical antipsychotic medication. It’s FDA approved to treat a few mental health conditions, including schizophrenia and bipolar disorder. It comes as an immediate-release tablet and an extended-release tablet (Seroquel XR). Depending on the condition being treated, Seroquel can be prescribed for children as young as 10 years old.
It’s common to want to know what side effects to expect when starting a new medication. And reading that weight gain is a side effect of Seroquel can spark a concern. How likely is this side effect? How much weight might you gain? Let’s discuss the facts surrounding Seroquel and weight gain, plus a few tips for managing weight changes should they happen to you.
In short, yes. Seroquel can cause weight gain. But everyone’s experience with the medication is unique. So it’s possible you may take Seroquel without much or any change to your body weight.
It’s common for antipsychotic medications to cause weight gain. But not every medication in this class has the same risk when it comes to this side effect.
Seroquel has a moderate risk of causing weight gain. This means there are some antipsychotics that are less likely than Seroquel to cause weight gain, such as Latuda (lurasidone). But there are also antipsychotics more likely to cause it, such as Zyprexa (olanzapine).
It’s possible to gain a significant amount of weight while taking Seroquel. In clinical trials, people gained an average of about 4 lbs after taking Seroquel for 26 weeks (about 6 months). But up to 23% of people gained at least 7% of their starting body weight. The medication seems to carry a similar risk of weight gain for both adults and children.
There are many factors that contribute to Seroquel’s ability to cause weight gain. This medication affects levels of several chemicals in the brain, including:
But these chemicals impact other areas of the body, too. They can stop your brain from receiving signals from your gut that you’re full after eating. This can make you feel hungrier and cause you to consume more calories without realizing it.
Seroquel can also negatively affect how your body releases and responds to its natural insulin. What’s more, it can cause your body to make more glucose (sugar) and fat cells.
All these actions combined can affect your body’s overall metabolism. Over time, this can lead to weight gain.
Long-term weight gain from Seroquel can raise your risk for other health conditions. These include Type 2 diabetes and high cholesterol, among others. It’s a good idea to discuss ways to manage or prevent weight gain with your healthcare provider when you first start taking Seroquel. Below are four steps you and your provider may decide to try.
As mentioned above, Seroquel might make you feel hungrier. But the types of foods you eat when you’re feeling this way can make quite an impact when it comes to weight gain.
Eating “healthy” looks different for everyone, and it’s often easier said than done. Making small adjustments to your usual eating habits is a good starting point. You’re also more likely to stick with smaller changes longer than if you try to make big changes.
Some suggestions you could try include:
Choosing snacks that are high in protein and fiber
Meal prepping ahead of time instead of making meal decisions when you’re hungry
Eating a variety of fruits and vegetables that you like
Drinking more water throughout the day
Picking foods that have unsaturated fats, such as avocado and nuts, rather than saturated fats
Limiting foods that have added sugars
Exercising is a great way to help boost your metabolism when Seroquel is slowing it down. It can also provide added benefits when it comes to your mental health. The “best” exercise plan is unique for everyone. So it’s a good idea to discuss what’s right for you with your healthcare provider.
Some simple ways to add more activity into your day could include:
Taking the stairs instead of the elevator or escalator
Extending your walk with your dog by a few minutes
Parking farther away than you usually would from store entrances
Putting on your favorite tunes and dancing for a few minutes
Doing a few sit-ups or push-ups during commercial breaks while watching TV
Alcohol can contribute to weight gain. Like Seroquel, alcohol slows down your metabolism. It also adds extra calories. Cutting back on how much or how often you drink can help if you’re trying to lose or maintain body weight.
Good to know: Alcohol and Seroquel interact with each other, too. The combination can worsen side effects, such as dizziness or drowsiness. Alcohol can also worsen symptoms of your mental health condition and make Seroquel less effective. So, weight gain aside, it’s a good idea to avoid or limit alcohol while taking this medication.
If lifestyle changes aren’t enough to help manage weight gain with Seroquel, your provider may suggest weight-loss medications. These aren’t appropriate for everyone, as they have risks of their own. But they can be helpful for some people.
No medications are FDA approved for antipsychotic-related weight gain. But some medications are supported by clinical evidence for chronic weight management, including:
Metformin, a popular diabetes medication
Topiramate (Topamax), a medication taken for seizures and migraines
Aripiprazole (Abilify), another antipsychotic that can sometimes cause weight loss
Semaglutide (Ozempic, Wegovy), an injectable medication approved for Type 2 diabetes and weight loss
Liraglutide (Victoza, Saxenda), an injectable medication that’s similar to semaglutide
All antipsychotics have some risk of weight gain. But there are several options that have a lower risk of weight gain than Seroquel. It may be worth discussing these alternatives with your healthcare provider.
Antipsychotics that tend to cause little to no weight gain include:
Haloperidol (Haldol)
Ziprasidone (Geodon)
Lurasidone
Cariprazine (Vraylar)
Fluphenazine
Keep in mind that switching antipsychotics isn’t always the right option. You may find that these are less effective for your symptoms than Seroquel. They may also cause other unwanted side effects, such as restlessness or uncontrollable body movements.
Seroquel (quetiapine) can cause weight gain for some people. In studies, people reported gaining an average of about 4 lbs after taking Seroquel for about 6 months. But some people may gain 7% or more of their starting body weight.
There are ways to help combat this Seroquel side effect. Diet, exercise, and healthy lifestyle choices can limit weight gain. There are also medications that your healthcare provider may prescribe to help you lose weight. Discuss options for managing body weight with Seroquel with your provider.
