Buy Mysimba 8mg/90mg Prolonged-Release Tablets

What Is Mysimba?

Mysimba is a prescription weight-loss tablet containing naltrexone and bupropion. These prolonged-release tablets work on areas of the brain involved in appetite and food cravings, supporting weight loss when combined with a reduced-calorie diet and increased physical activity. Together, the two active ingredients affect brain pathways involved in hunger, cravings, and reward.

Weight-loss medicines like Mysimba are typically prescribed when lifestyle changes alone haven’t produced sufficient results.

What Is Mysimba Used For?

Mysimba is used to support weight loss and long-term weight management in adults with obesity, or overweight individuals with weight-related health risks such as high blood pressure, type 2 diabetes, or high cholesterol. Weight-loss medications may be considered for someone with:

• A BMI of 30 or above (obesity)
• A BMI of 27 or above with weight-related conditions

Mysimba is normally prescribed once diet and exercise alone haven’t achieved the desired level of weight loss.

What Are the Benefits of Using Mysimba?

Potential benefits of Mysimba, when used appropriately, include:

• Reduced appetite and food cravings
• Improved portion control
• Support for gradual, sustained weight loss
• Potential improvements in weight-related health risks

Even modest weight loss can improve health outcomes — NICE guidance notes that losing 5–10% of body weight can significantly reduce cardiovascular and metabolic risk factors.

How Does Mysimba Work for Weight Loss?

Mysimba works by affecting appetite regulation and reward pathways in the brain, targeting two key systems involved in hunger and food cravings. Bupropion stimulates neurons in the hypothalamus that help control appetite, while naltrexone blocks opioid receptors linked to the brain’s reward system. Together, they help reduce cravings and emotional eating patterns.

Unlike medications that act on digestion or blood sugar, Mysimba primarily works on the brain’s appetite control systems, which can help support healthier eating habits over time.

How Effective Is Mysimba for Weight Loss?

Clinical studies show Mysimba can support meaningful weight loss when combined with lifestyle changes, with many patients losing around 5–10% of their starting body weight over one year of treatment. Research assessed by the European Medicines Agency found that patients taking Mysimba lost more weight on average than those following lifestyle changes alone.

NICE also highlights that losing even a small percentage of body weight can improve blood pressure, blood sugar, and cholesterol levels — helping reduce the risk of later health complications, such as cardiovascular disease and type 2 diabetes.

Who Can Use Mysimba?

Mysimba is intended for adults with obesity, or overweight individuals with weight-related health conditions. A healthcare professional must assess suitability. It may be considered if:

• BMI is 30 or above
• BMI is 27 or above with weight-related conditions

Mysimba may not be suitable for people who:

• Are pregnant or breastfeeding
• Have uncontrolled high blood pressure
• Have a seizure disorder or epilepsy
• Have severe liver disease

A doctor or pharmacist will assess medical history and lifestyle factors to help determine the most appropriate weight-loss management option for long-term health.

Mysimba Dosages

Mysimba tablets are taken daily, with the dose gradually increased over four weeks to reduce the risk of side effects. The tablets are prolonged-release, meaning the medication is released slowly throughout the day.

How Many Mysimba Tablets Per Day?

Week	Dose
Week 1	One tablet once daily
Week 2	One tablet twice daily
Week 3	Two tablets in the morning, one tablet in the evening
Week 4 onwards	Two tablets twice daily (maximum dose of four tablets per day)

A healthcare provider may adjust the dose based on how treatment is being tolerated.

Is Mysimba Safe?

Mysimba is generally considered safe when prescribed appropriately and taken as directed by a healthcare professional, and has been approved for weight management in adults within Europe and the UK. Medicines used in the UK are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA), which monitors safety, quality, and effectiveness.

However, Mysimba may not be suitable for everyone and can cause side effects — a medical assessment is required before starting treatment.

How to Take Mysimba for the Best Weight Loss Results

As with most weight management medications, getting the most from Mysimba means combining it with healthy lifestyle changes, such as:

• Following a reduced-calorie, balanced diet
• Increasing physical activity
• Monitoring food intake and portion sizes
• Maintaining regular medical follow-ups

The NHS recommends adults aim for at least 150 minutes of moderate physical activity per week to support overall health and weight management.

Is Mysimba Available Online in the UK?

Mysimba is a prescription-only medicine in the UK, meaning it can only be accessed following an assessment by a qualified healthcare professional. An online consultation for Mysimba can be started with Express Home pharmacy, and one of our expert clinicians will provide a prescription if treatment is suitable.

Can You Get Mysimba on the NHS?

In some cases, Mysimba may be available through specialist weight-management services within the NHS if eligibility criteria are met. Access may vary depending on local healthcare policies.

Standard Mysimba Prices

The price of Mysimba can vary depending on the pharmacy, pack size, and whether it’s obtained privately or through NHS services. Private prescriptions often involve the cost of both the consultation and the medication itself. At Express Home pharmacy, the price of Mysimba starts from £99.99.

How Long Does Mysimba Take to Work?

Mysimba begins affecting appetite signals soon after starting treatment, but noticeable weight loss usually develops gradually over several weeks. Treatment progress is typically reviewed after 16 weeks if at least 5% of starting body weight hasn’t been lost by that point, treatment may be stopped.

How Long Does Mysimba Stay in Your System?

The active ingredients in Mysimba have half-lives meaning they remain in the body for several hours after each dose, though most of the medication is eliminated within a few days of stopping treatment. Because Mysimba tablets are prolonged-release, the medication is released gradually throughout the day.

Potential Mysimba Side Effects

Like all medicines, Mysimba may cause side effects. Many are mild and improve as the body adjusts to treatment. Common side effects include:

• Nausea
• Headache
• Constipation
• Dry mouth
• Insomnia
• Dizziness

Seek urgent medical help if you experience: Seizures; severe allergic reactions (swelling of the face, throat, or difficulty breathing); severe mood changes or suicidal thoughts; or signs of high blood pressure, like severe headaches or chest pain. Contact a healthcare professional immediately if any severe symptoms occur.

How Long Do the Side Effects Last?

Most side effects appear during the early weeks of treatment and improve as the body adapts to the medication. Gradually increasing the dose helps reduce the likelihood of side effects.

How Mysimba Interacts With Other Medicines

Mysimba may interact with certain medications and medical conditions. A healthcare provider should always be told about any medicines being taken. Important interactions include:

• Oral contraceptives (severe vomiting or diarrhoea may reduce effectiveness)
• Antidepressants or psychiatric medicines
• Opioid medicines (due to naltrexone’s opioid-blocking effects)
• Medicines that increase seizure risk

Mysimba is not recommended during pregnancy or breastfeeding, as weight-loss medicines are generally not considered safe during these periods.

Mysimba Alternatives

Other weight-management medicines may be available depending on health needs and eligibility, including:

• Orlistat (generic Xenical) — reduces fat absorption
• Wegovy — appetite regulation
• Mounjaro — hormone-based treatment

A healthcare professional can help determine the most suitable option for individual circumstances.
