What Does Mysimba Cost in the Netherlands?
Mysimba (naltrexone/bupropion) is a prescription weight loss medication that costs between €90 and €140 per month in the Netherlands, depending on the pharmacy and the phase of the titration schedule. This medication is prescribed to adults with a BMI of 30 or higher, or a BMI of 27 or higher combined with weight-related comorbidities. Unlike GLP-1 medications such as Ozempic or Wegovy, Mysimba works through a different mechanism, combining naltrexone and bupropion to influence hunger signals and the brain's reward system.
Mysimba costs and insurance coverage are important considerations for many people choosing a weight loss treatment. In this article, we discuss exact prices, health insurance reimbursement policies, expected out-of-pocket expenses, and how Mysimba compares cost-wise to other weight loss medications.
How Much Does Mysimba Cost Per Month?
The price of Mysimba depends on the phase of the titration schedule. The medication is gradually increased over four weeks to the full maintenance dose.
Price Breakdown Per Treatment Phase
During the first week, you take only 1 tablet per day (morning). In week 2, this increases to 2 tablets, in week 3 to 3 tablets, and from week 4 onwards you take the full dose of 4 tablets per day (2 in the morning, 2 in the evening). Each tablet contains 8 mg naltrexone and 90 mg bupropion.
| Treatment Phase | Dosage | Tablets Per Day | Estimated Monthly Cost | |---|---|---|---| | Week 1 (titration) | 1 tablet in the morning | 1 | €30 - €45 | | Week 2 (titration) | 1 tablet twice daily | 2 | €50 - €70 | | Week 3 (titration) | 2 morning, 1 evening | 3 | €70 - €100 | | Week 4+ (maintenance) | 2 tablets twice daily | 4 | €90 - €140 |
The pharmacy retail price (AVP) for a package of 112 tablets (28 days maintenance dose) is approximately €115 to €130 according to the Farmacotherapeutisch Kompas. Online pharmacies sometimes offer lower prices, but you always need a prescription.
Annual Costs for Long-Term Use
With long-term use at the full maintenance dose, annual costs amount to approximately €1,100 to €1,680. This makes Mysimba cheaper than injectable GLP-1 medications like Wegovy (approximately €200-€300 per month), but more expensive than some generic weight loss aids.
Is Mysimba Covered by Dutch Health Insurance?
This is the key question for many patients. Mysimba is currently NOT covered by the basic Dutch health insurance package. The Zorginstituut Nederland (National Health Care Institute) ruled in 2016 that naltrexone/bupropion does not meet the criteria for inclusion in the basic package, primarily because the therapeutic added value compared to lifestyle interventions was insufficiently demonstrated for the requested price.
Why Doesn't Basic Insurance Cover Mysimba?
The Zorginstituut bases its assessment on three criteria:
This decision is separate from the fact that Mysimba is indeed an EMA-approved medication with proven efficacy. It simply means that the Dutch government considers the cost-benefit ratio insufficient for collective financing.
Supplementary Insurance and Mysimba
Some insurers offer partial reimbursement for weight loss medication through supplementary packages. This varies significantly between insurers and between years. In practice, most supplementary insurances do not specifically cover Mysimba, but there are exceptions:
Always check your policy conditions or contact your insurer. Look specifically for terms like "obesity medication," "weight loss medication," or "naltrexone/bupropion" in the reimbursement list.
What Are the Out-of-Pocket Expenses for Mysimba?
Because Mysimba is not included in the basic package, you essentially pay the full cost yourself. There is no "co-payment" in the traditional sense (as with medications that are covered), but rather full self-payment.
Understanding the Difference
It is important to understand the distinction:
This means you pay €90-€140 monthly out of pocket, unless your supplementary insurance covers a portion.

How Does Mysimba Compare Cost-Wise to Other Weight Loss Medications?
To make an informed choice, it is useful to compare Mysimba costs with other available weight loss options in the Netherlands.
| Medication | Active Ingredient | Average Monthly Cost | Basic Insurance | Average Weight Loss | |---|---|---|---|---| | Mysimba | Naltrexone/bupropion | €90 - €140 | No | 4-5% (56 weeks) | | Ozempic | Semaglutide 1mg | €120 - €180 | Diabetes only | 10-15% (68 weeks) | | Wegovy | Semaglutide 2.4mg | €200 - €300 | No | 15-17% (68 weeks) | | Mounjaro | Tirzepatide | €200 - €350 | No | 15-22% (72 weeks) | | Orlistat (Alli) | Orlistat | €40 - €60 | No | 3-4% (52 weeks) |
This comparison shows that Mysimba falls in the mid-range price segment. However, its effectiveness is more limited than GLP-1 medications. Those seeking greater weight loss may want to explore GLP-1 medication options, although these are also more expensive.
How Does Mysimba Work for Weight Loss?
Mysimba combines two active substances that each work through a different mechanism:
Naltrexone: The Opioid Receptor Antagonist
Naltrexone blocks opioid receptors in the brain, particularly in the reward center. This reduces cravings for food linked to emotional eating or binge eating. Naltrexone was originally developed for treating alcohol and opioid addiction.
Bupropion: The Dopamine-Norepinephrine Reuptake Inhibitor
Bupropion increases the concentration of dopamine and norepinephrine in the brain. This leads to reduced hunger and slightly increased energy expenditure. Bupropion was originally developed as an antidepressant (Wellbutrin) and smoking cessation aid (Zyban).
The combination of both substances has a synergistic effect on the hypothalamic hunger center and the mesolimbic reward system. Clinical studies show that the combination is more effective than either substance alone (Greenway et al., 2010, The Lancet).
What Do Clinical Studies Say About Mysimba's Effectiveness?
The efficacy of naltrexone/bupropion was investigated in the COR (Contrave Obesity Research) study program, consisting of four large randomized, double-blind, placebo-controlled trials.
Key Study Results
For comparison: in the STEP-1 trial with semaglutide 2.4mg (Wegovy), participants lost an average of 14.9% of body weight (Wilding et al., 2021). This partly explains why GLP-1 medications are becoming increasingly popular. More information about these medications can be found on our Mounjaro page.
Where Can You Buy Mysimba in the Netherlands?
Mysimba is available by prescription only. You can obtain it through:
1. Your GP: can prescribe Mysimba as part of a weight management treatment 2. An obesity clinic: specialized clinics that prescribe weight loss medication 3. Online doctor consultations: some platforms offer online consultations after which a prescription can be issued 4. The pharmacy: after receiving the prescription, you can collect it at any pharmacy
Note: never buy Mysimba without a prescription through unofficial channels. Counterfeit products circulate that can be dangerous. A registered physician must always assess whether Mysimba is safe for you, given the contraindications (uncontrolled hypertension, epilepsy, eating disorders, concurrent use of MAO inhibitors).

Who Is Eligible for Mysimba?
According to EMA guidelines, Mysimba is indicated for:
You can calculate your BMI to see if you qualify. Mysimba is always prescribed as an adjunct to a reduced-calorie diet and increased physical activity.
Contraindications
Mysimba must not be used in cases of:
What Are the Side Effects of Mysimba?
The most common side effects of Mysimba relate to the gastrointestinal tract and nervous system:
Very Common (more than 1 in 10 users)
Common (1 in 10 to 1 in 100 users)
Most side effects diminish after the first 2-4 weeks of use. The gradual titration schedule is specifically designed to minimize gastrointestinal side effects. Contact your doctor if symptoms persist or are severe.
Tips to Reduce Mysimba Costs
While options are limited, there are some strategies to reduce costs:
For those who find Mysimba costs prohibitive but would benefit from pharmaceutical support for weight loss, it may be worthwhile to compare prices of other treatments.
Frequently Asked Questions About Mysimba Costs and Coverage
Can I Submit a Mysimba Claim to My Health Insurer?
You can submit an invoice to your health insurer, but the chance of reimbursement from the basic package is nil. Only if your supplementary insurance explicitly covers obesity medication do you have a chance of (partial) reimbursement. Check your policy conditions under "medications" or "obesity treatment."
Is Mysimba Cheaper Than Ozempic?
Yes, Mysimba is generally cheaper than Ozempic. Mysimba costs €90-€140 per month, while Ozempic costs €120-€180 per month. However, the difference in effectiveness is significant: Ozempic leads to an average of 10-15% weight loss versus 4-5% with Mysimba.
How Long Should I Use Mysimba?
Guidelines recommend evaluating treatment after 16 weeks. If you have not lost at least 5% of your body weight by then, discontinuation is recommended. With successful treatment, Mysimba can be continued long-term, but the optimal treatment duration has not been established.
Will Mysimba Be Covered by Basic Insurance in 2026?
There are currently no indications that the Zorginstituut Nederland will revise its position on Mysimba. The focus of reimbursement policy for obesity medication is more on newer GLP-1 medications, which have greater effectiveness. Monitor the Zorginstituut website for current developments.
Can I Combine Mysimba with Other Weight Loss Medications?
No, Mysimba should not be combined with other weight loss medications without explicit medical advice. Combination with GLP-1 agonists has not been studied in clinical trials and is not recommended. Always discuss with your doctor which treatment is most suitable for your situation.
Conclusion
Mysimba costs average €90 to €140 per month at the full maintenance dose, and the medication is not covered by basic Dutch health insurance. The total annual investment amounts to €1,100 to €1,680 out of pocket. While Mysimba is a proven effective weight loss medication, its effectiveness is more limited than newer GLP-1 medications.
For those considering pharmaceutical support for weight loss, it is important to weigh both costs and expected results in the decision. A consultation with a specialized physician can help determine the right choice based on your personal situation, BMI, and any comorbidities.
