Overview
Managing bipolar disorder is challenging enough without the added stress of weight fluctuations. Many mood stabilizers can cause significant weight gain, adding to the emotional and physical toll. Thankfully, Lamictal (lamotrigine) stands out—it’s less likely to affect your weight, and some people even experience slight weight loss. But don’t just breathe a sigh of relief yet; knowing how Lamictal might work for you is essential. Keep reading to explore what the research says, and be sure to talk to your doctor about whether Lamictal is the right choice for your treatment. Weight changes should be the last thing you need to worry about while managing your health.
Does Lamictal cause weight gain?
Weight gain is a common concern for those taking medication to manage bipolar disorder. Many mood stabilizers, such as lithium and Depakote (valproate), are notorious for causing significant weight gain. Similarly, atypical antipsychotics like Clozaril (clozapine) and Zyprexa (olanzapine) can lead to a noticeable increase in weight. Even some antidepressants, including Paxil (paroxetine) and Remeron (mirtazapine), have weight gain as a side effect.
Why consider Lamictal?
Given the potential for weight gain with many mood stabilizers, choosing the right medication is crucial. If maintaining a healthy weight concerns you, Lamictal (lamotrigine) might be a better option. Unlike other mood stabilizers, Lamictal has a much lower risk of causing weight gain. Clinical trials have shown that less than 5% of people taking Lamictal experience weight gain, making it a more favorable choice for those worried about this side effect.
Factors influencing weight gain
It’s important to remember that various factors, including the severity of bipolar disorder and other existing health conditions, can influence weight gain. Bipolar disorder itself can increase your appetite or alter your metabolism, leading to weight gain that may not be directly related to the medication.
If you’re managing bipolar disorder, consult with your healthcare provider promptly. With personalized advice and treatment plan, ensure optimal mental health and overall well-being,” advises Dr. Richard Honaker at Your Doctors Online.
Managing weight while on Lamictal
- Consult a nutritionist: If you’re concerned about weight gain during your treatment, consider asking your doctor for a referral to a nutritionist. A nutritionist can help you create a meal plan that supports a healthy weight.
- Monitor your mood: Weight gain isn’t the only thing to watch out for. Mood changes may also indicate that your current medication isn’t as effective as it should be. If you notice continued mood swings, talking to your doctor is important.
- Personalized treatment: Everyone responds differently to mood stabilizers. It may take time to find the medication that works best for you. Never stop taking your medication without consulting your doctor, as this can lead to serious consequences.
Lamictal’s minimal impact on weight gain can be a significant advantage for those managing bipolar disorder. Still, it’s essential to consider all factors and work closely with your healthcare provider to determine the best treatment plan.

Can you lose weight while on Lamictal?
Yes, losing weight while taking Lamictal (lamotrigine) is possible, although it’s rare. Lamictal, primarily used as an anticonvulsant and mood stabilizer for bipolar disorder and seizure disorders, is known for being “weight-neutral.” This sets it apart from other mood stabilizers, which often contribute to weight gain.
Weight loss in clinical trials
In clinical trials, weight loss was observed slightly more often than weight gain among those taking Lamictal. For example:
- Epilepsy patients: About 5% of adults with epilepsy experienced weight loss while on Lamictal.
- Bipolar I disorder patients: On the flip side, only 1% to 5% of individuals with bipolar I disorder reported weight gain.
It’s worth noting that while weight changes were documented, the exact amount of weight lost or gained wasn’t specified in these trials.
Lamictal’s weight-neutral profile
In 2021, a comprehensive review of 13 studies on lamotrigine highlighted that this medication is not linked to significant weight gain. This research confirmed that Lamictal is generally “weight-neutral,” especially compared to mood stabilizers like lithium, valproic acid, and carbamazepine, which are more likely to cause weight gain.
Factors influencing weight changes
Even though Lamictal itself doesn’t usually cause weight gain, several factors can still influence your weight while on this medication, including:
- Severity of Bipolar disorder: Bipolar disorder can impact metabolism and appetite, sometimes leading to weight gain independent of medication.
- Other health conditions: Co-existing conditions and their treatments can also affect how your body responds to Lamictal.
Considerations for weight management
If weight management is a concern while you’re on Lamictal, here are a few steps you can take:
- Monitor changes: Keep track of any weight changes and discuss them with your doctor.
- Lifestyle adjustments: Work with a nutritionist to develop a diet and exercise plan that supports a healthy weight.
- Stay informed: Regularly review your treatment plan with your healthcare provider to ensure that Lamictal is still the best option for managing your condition without unwanted side effects.
While weight loss on Lamictal is uncommon, its reputation as a weight-neutral medication makes it a valuable option for those looking to manage bipolar disorder without the added stress of significant weight fluctuations.
How does lamotrigine affect weight?
Lamictal (lamotrigine) stands out among medications used to treat bipolar disorder and seizures due to its minimal impact on weight. Unlike many anticonvulsants, which often contribute to weight gain, Lamictal has a unique mechanism of action that reduces the likelihood of significant weight changes.
The mechanism behind Lamictal’s weight-neutral effect
Lamictal modulates certain brain chemicals, particularly glutamate, which is crucial in mood stabilization and seizure control. Unlike other anticonvulsants that enhance the effects of GABA (a brain chemical that can cause sedation and weight gain), Lamictal reduces glutamate activity. This “activating” effect may be why Lamictal doesn’t typically cause weight gain and may even lead to slight weight loss in some cases.
Research findings on Lamictal and weight changes
Several studies have highlighted Lamictal’s impact on weight:
- Weight loss: In one study, patients who took Lamictal for six weeks lost an average of 1 kg (about 2.2 pounds).
- Comparison with other anticonvulsants: In another study, a common anticonvulsant, gabapentin, led to an average weight gain of 1.8 kg (about 4 pounds) in the same period.
- Prevalence of weight changes: While weight loss on Lamictal is uncommon, it occurs in a small percentage of people (less than 1%).
Why Lamictal may be a preferred choice?
Lamictal’s unique impact on brain chemistry makes it a preferred option for those concerned about weight gain while managing bipolar disorder or seizure disorders. By focusing on glutamate rather than GABA, Lamictal provides mood stabilization and seizure control without the added burden of weight gain, a common side effect of many mood stabilizers and anticonvulsants.
If you’re on Lamictal or considering it as a treatment option, you can be reassured by its reputation as a weight-neutral medication. While individual experiences may vary, the risk of significant weight gain with Lamictal is low, making it a compelling choice for those managing bipolar disorder or seizures without wanting to add weight fluctuation to their list of concerns.

Drug interactions and other considerations
Lamictal’s effectiveness and side effect profile can be influenced by other medications and conditions:
- Drug interactions: Taking Lamictal with drugs like valproic acid or divalproex sodium can increase the amount of Lamictal in your body, raising the risk of side effects. Conversely, drugs like carbamazepine or phenytoin can reduce Lamictal levels, potentially making it less effective.
- Birth control and antibiotics: Estrogen-containing birth control pills and the antibiotic rifampin can decrease Lamictal levels by about 50%, potentially reducing its efficacy.
- Liver and kidney health: If you have liver or kidney issues, your doctor may adjust your dosage or consider alternative medications.
Pregnancy and breastfeeding
The safety of Lamictal during pregnancy is not fully established. If you are pregnant or planning to become pregnant, consult your doctor. Additionally, since Lamictal can pass into breast milk, it may cause side effects in breastfeeding infants, so discussing feeding options with your healthcare provider is important.
While Lamictal is generally weight-neutral, its other side effects and potential drug interactions make it crucial to consult with your doctor regularly. This ensures that your treatment plan is both safe and effective, helping you manage bipolar disorder without unnecessary risks.
