Alcohol and weight loss medications don’t usually come up in the same conversation — but they should.
At Health Express Clinics in Lewisville, we commonly see patients who are prescribed Contrave or Qsymia for weight loss, and many are surprised to learn about the serious risks when mixing alcohol with these medications.
Today, let’s have an honest, medically grounded discussion about Contrave vs Qsymia and alcohol, how they interact, and why it matters far more than most patients realize.
Understanding Contrave and Qsymia: A Quick Refresher
Before we dive into alcohol interactions, let’s revisit the basics:
- Contrave combines bupropion (an antidepressant/smoking cessation aid) and naltrexone (used for addiction treatment).
- Qsymia combines phentermine (a stimulant appetite suppressant) and topiramate (an anticonvulsant often used for migraines).
Both medications are powerful tools for weight loss but affect brain chemistry in ways that can become complicated when alcohol enters the picture.
How Alcohol Interacts with Contrave and Qsymia
When you add alcohol to either Contrave or Qsymia, the risks aren’t just theoretical — they are very real and can be dangerous. Here’s how each drug is affected:
1. Alcohol and Contrave
Major Concerns:
- Increased Seizure Risk: Bupropion by itself lowers the seizure threshold. Alcohol withdrawal or binge drinking also increases seizure risk, making the combination particularly hazardous.
- Mood Instability: Alcohol is a central nervous system depressant. Mixing it with bupropion and naltrexone can worsen depression, anxiety, or mood swings — the very issues Contrave is often helping to manage.
- Liver Stress: Naltrexone is metabolized through the liver. Adding alcohol increases the liver’s workload, raising the risk of liver damage.
Clinical Insight:
At Health Express Clinics, we always screen for alcohol use before starting Contrave and advise strict limitation or complete avoidance of alcohol while taking it.
2. Alcohol and Qsymia
Major Concerns:
- Enhanced Sedation and Dizziness: Both topiramate and alcohol are sedatives. When combined, the effects amplify, making it easier to experience confusion, impaired judgment, or dangerous falls.
- Metabolic Side Effects: Phentermine is a stimulant, and alcohol is a depressant. This push-pull on the nervous system can cause erratic heart rates, blood pressure fluctuations, or dehydration.
- Memory and Cognitive Issues: Topiramate on its own can cause memory lapses. Alcohol worsens this problem, which can seriously affect daily functioning.
Clinical Insight:
Patients at Health Express Clinics who are prescribed Qsymia are cautioned that even small amounts of alcohol can have unexpectedly strong effects while on the medication.
5 Common Questions About Contrave, Qsymia, and Alcohol
1. Can I have “just one drink” while taking Contrave or Qsymia?
Answer:
There’s no truly safe amount, but occasional, minimal alcohol might be tolerated better with Qsymia than Contrave.
With Contrave, because of the seizure risk, we strongly discourage any alcohol use.
2. What happens if I accidentally drink while on Contrave or Qsymia?
Answer:
One drink may not cause a medical emergency, but pay close attention to any symptoms: dizziness, confusion, nausea, palpitations, or mood swings.
If symptoms are severe, seek medical help immediately.
3. Does drinking reduce the effectiveness of weight loss medications?
Answer:
Yes. Alcohol is not only high in empty calories but also affects metabolism and appetite regulation, undermining the benefits of Contrave or Qsymia.
4. Which is riskier with alcohol: Contrave or Qsymia?
Answer:
Contrave is riskier overall due to the potential for seizures and mood destabilization.
Qsymia carries risks too but tends to cause more cognitive impairment and accident risks when mixed with alcohol.
5. Can I stop Contrave or Qsymia temporarily if I plan to drink?
Answer:
No, stopping and starting medications like these is dangerous. They require a careful titration schedule to minimize side effects and prevent withdrawal effects.
Talk to your doctor if you anticipate needing to drink alcohol regularly — medication changes might be necessary.
Why the Risks Are Higher Than You Think
A few factors make alcohol even more dangerous with weight loss medications:
- Dehydration: Both alcohol and these medications can dehydrate the body, increasing side effect intensity.
- Electrolyte Imbalance: Alcohol affects sodium and potassium levels. Topiramate in Qsymia can also affect electrolytes, compounding the risk.
- Cognitive Impairment: Patients often underestimate how much their judgment and reflexes are impaired when combining alcohol with medications.
At Health Express Clinics in Lewisville, we frequently counsel patients who are surprised to learn that the occasional weekend drink might not be so harmless when added to their medication regimen.
Real-World Scenarios We See at Health Express Clinics
- Case 1: A patient taking Contrave who consumed three alcoholic beverages at a party later experienced a mild seizure. Fortunately, they recovered fully but needed a complete medication reassessment.
- Case 2: A patient on Qsymia had a fall after mixing wine with medication, resulting in a fractured wrist.
- Case 3: A young professional on Contrave noticed worsening anxiety and insomnia after moderate weekend drinking, requiring dosage adjustments and behavioral health support.
These examples are why we proactively address alcohol risks with every patient starting weight loss medication.
Tips for Patients: How to Stay Safe
✅ Be Honest with Your Doctor: Always disclose your alcohol use habits before starting medications.
✅ Commit to Low or No Alcohol: Especially critical if starting Contrave.
✅ Plan Social Events Carefully: Opt for mocktails or sparkling water when out with friends.
✅ Stay Hydrated: If you accidentally consume alcohol, drink extra water and monitor for side effects.
✅ Know the Signs of Trouble: Dizziness, confusion, rapid heart rate, seizures, or mood swings require immediate medical attention.

In summary:
