Medication and Drug Interactions


Hello, pharmacist: I would like to ask if Zyprexa, Depakote, Seroquel, and Restoril contain steroids.
I often hear that taking psychiatric medications can lead to weight gain, and I am unsure if this is due to the presence of steroids.
During the time I have been taking these medications, I have gained a significant amount of weight, have difficulty losing fat, and am experiencing overall swelling.
Additionally, my family has a history of kidney issues.
While inquiring about weight gain at the clinic, I learned about the weight loss medication Contrave.
I would like to know if it is safe to combine Contrave with Zyprexa, Depakote, Seroquel, and Restoril.
Thank you very much for taking the time to respond.

Dr. Liu Huiya reply Pharmacology


Hello An Hsu: The medications Zyprexa, Depakote, Seroquel, and Trazodone do not contain steroids.
Regarding your concern about psychiatric medications causing weight gain, generally speaking, the classes of psychiatric medications that may lead to weight gain include antipsychotics, mood stabilizers (such as lithium, Depakote, and Tegretol), and certain antidepressants (like Remeron).
The medication you inquired about, Depakote, is more likely to cause weight gain.
However, the reasons behind weight gain are usually multifactorial, including genetic factors, changes in daily routine, dietary habits, and decreased physical activity.
Therefore, if you wish to lose weight, it is advisable to consult your psychiatrist first and not to purchase weight loss medications on your own.
Although Contrave is currently one of the two weight loss medications approved by the Department of Health (the other being "Roche's Xenical"), it acts on the central nervous system and is not suitable for patients currently taking psychiatric medications.
Thank you for your letter!

More Info


When it comes to psychiatric medications, concerns about weight gain are quite common among patients. The medications you mentioned—Zyprexa (Olanzapine), Depakote (Divalproex Sodium), Seroquel (Quetiapine), and Ambien (Zolpidem)—are not corticosteroids, but they can indeed lead to weight gain and other metabolic side effects.

Understanding Weight Gain with Psychiatric Medications
Weight gain associated with psychiatric medications can occur for several reasons, including changes in metabolism, increased appetite, and alterations in how the body processes food. Medications like Zyprexa and Seroquel are known to have a higher propensity for causing weight gain compared to other psychiatric medications. This is primarily due to their effects on neurotransmitters such as serotonin and histamine, which can increase appetite and lead to cravings for high-calorie foods.

1. Zyprexa (Olanzapine): This atypical antipsychotic is particularly notorious for causing weight gain. Studies have shown that patients can gain significant weight within the first few months of treatment. The mechanism is thought to involve increased appetite and changes in metabolism.

2. Seroquel (Quetiapine): Similar to Zyprexa, Seroquel can also lead to weight gain, although the extent may vary among individuals. It can cause sedation, which may lead to decreased physical activity and further contribute to weight gain.

3. Depakote (Divalproex Sodium): This medication, primarily used for mood stabilization and seizure control, can also lead to weight gain. It is thought to affect metabolic pathways and appetite regulation.

4. Ambien (Zolpidem): While primarily a sleep aid, Ambien is less commonly associated with weight gain compared to the other medications mentioned. However, sleep disturbances and changes in sleep patterns can indirectly affect weight.

Fluid Retention and Edema
The swelling and fluid retention you mentioned could be related to the medications, particularly if you have a family history of kidney issues. Some psychiatric medications can cause fluid retention, which may lead to a temporary increase in weight that is not necessarily due to fat gain. It is essential to monitor these symptoms closely, especially given your family history of kidney disease.

Combining Medications
Regarding the use of weight loss medications like Naltrexone/Bupropion (often referred to as Contrave) with your current psychiatric medications, it is crucial to consult with your healthcare provider. Combining medications can lead to interactions that may affect their efficacy or increase the risk of side effects. Your doctor will consider your overall health, the severity of your psychiatric condition, and the potential benefits and risks of adding a weight loss medication.

Managing Weight Gain
If you are experiencing significant weight gain, it is essential to address this with your psychiatrist. They may consider adjusting your medication regimen or incorporating lifestyle changes such as dietary modifications and exercise. Here are some strategies that may help:
1. Dietary Changes: Focus on a balanced diet rich in whole foods, such as fruits, vegetables, lean proteins, and whole grains. Reducing processed foods and sugary snacks can help manage weight.

2. Regular Exercise: Incorporating physical activity into your routine can help counteract weight gain. Aim for at least 150 minutes of moderate aerobic activity each week, along with strength training exercises.

3. Monitoring: Keep track of your weight and any changes in your body. Regular check-ins with your healthcare provider can help manage any side effects from medications.

4. Psychological Support: Consider discussing your concerns with a therapist or counselor who can provide support and strategies for coping with weight changes and body image issues.

In conclusion, while psychiatric medications can lead to weight gain, understanding the underlying mechanisms and working closely with your healthcare provider can help manage these concerns effectively. Always consult your doctor before making any changes to your medication regimen or starting new treatments.
