Here Is Some Important Information About Contrave
There is growing interest in medications that may assist weight loss, including Contrave (Naltrexone/Bupropion). If you’ve been prescribed this medication, or you plan to discuss medication options with your doctor, it’s worth noting some important insights about it.
This article, written by the experts at Chemist2U, will guide you through its usage, and discuss how it interacts with other medications. We’ll also provide insights on how you can conveniently order home delivery of your medications, so read along.
1. How does Contrave work?
This medication is prescribed for adults who are overweight or obese and are experiencing weight-related health issues. It contains two active ingredients: naltrexone and bupropion. Bupropion, known primarily as an antidepressant, aids in reducing appetite. Naltrexone, used in addiction treatment, helps suppress hunger and cravings.[1]
While the precise neurochemical interactions of these active ingredients are still being studied, it’s believed that they act on the hypothalamus and the mesolimbic dopamine circuit, leading to a feeling of fullness, reduced food intake, and increased energy expenditure.[2]
When you’re interested in topics like ‘Contrave benefits’, it’s important to note that it’s not a cure-all. It doesn’t directly treat other conditions linked to obesity, like high blood pressure, diabetes, or high cholesterol.[3] Moreover, Contrave (Naltrexone/Bupropion) should be part of a broader weight management strategy, including diet, exercise, and lifestyle changes.
2. How do you take Contrave?
Contrave (Naltrexone/Bupropion) is only available as an extended-release tablet, unlike other weight loss tablets like Phentermine and Topiramate, which are available in both extended-release and other forms.
This means it gradually releases its active ingredients to work over time. Generally, those prescribed Contrave (Naltrexone/Bupropion) start with one tablet each morning for the first week. In the second week, your doctor may add an evening tablet to your routine.
The Contrave dosage usually increases gradually each week. By the start of week four, you may be taking two tablets in the morning and two in the evening.[4]
It’s important not to exceed the dosage in your Contrave prescription. It is often taken with meals, but you may be asked to avoid high-fat meals to prevent increased exposure to the active ingredients. Also, remember that the tablets must be swallowed whole – no cutting, chewing, or crushing.
3. Who can take Contrave?
Contrave (Naltrexone/Bupropion) may be prescribed to adults with a Body Mass Index (BMI) of 30 kg/m² or more (classified as obese) or those with a BMI of 27 kg/m² or more (overweight), who also have weight-related health issues like hypertension, type 2 diabetes, or dyslipidemia.[5]
However, there are specific conditions where using Contrave (Naltrexone/Bupropion) is not advised. If you are pregnant, allergic to Naltrexone or Bupropion, have uncontrolled high blood pressure, have a history of seizures or eating disorders, have a history of bipolar disorder, are taking opioids regularly or intermittently or are dealing with opioid addiction, it might not be suitable for you.
4. Side effects of Contrave
Like any weight loss medication such as Xenical and Topomax, Contrave (Naltrexone/Bupropion) has potential side effects. Common side effects include nausea, dizziness, constipation, trouble sleeping, headaches, dry mouth, vomiting, and diarrhoea.
It’s crucial to be aware of serious side effects too, such as seizures, increased suicidal thoughts, the risk of opioid overdose, sudden opioid withdrawal, and allergic reactions.[6] If you experience any side effects, immediately reach out to your doctor, whether it’s through face-to-face or online consultation, for advice.
5. Contrave and other medications
When searching online for terms like ‘Contrave Australia’ or ‘Contrave for sustainable weight loss’, keep in mind that its effectiveness can be influenced by other medications you may be taking.
Contrave (Naltrexone/Bupropion) is metabolised by the enzyme CYP2D6. When co-administered with drugs that are also metabolised by this enzyme, like certain antidepressants, antipsychotics, beta-blockers, and Type 1C antiarrhythmics, it can increase the exposure of this enzyme in the body. This may necessitate a dosage adjustment.
Moreover, bupropion is broken down in the body by another enzyme called CYP2B6. Certain drugs, like ticlopidine and clopidogrel, can change how the body is exposed to bupropion and hydroxybupropion, and may also necessitate dosage adjustment. Other drugs, like Ritonavir, Lopinavir, and Efavirenz, can lower bupropion levels, which might make Contrave (Naltrexone/Bupropion) less effective.[7]
Discussing your current medication regimen with your doctor is crucial to preventing any adverse interactions and tailoring the treatment to your unique needs.
6. Medicines you should not use with Contrave
A key interaction to note is with Monoamine Oxidase Inhibitors (MAOIs). Since Bupropion, a component of Contrave (Naltrexone/Bupropion), inhibits the reuptake of dopamine and norepinephrine, it can significantly increase the risk of hypertensive reactions when used with MAOIs.[8]
To ensure safety, your doctor may instruct a gap of at least 14 days between discontinuing an MAOI and starting Contrave, and vice versa.
Additionally, opioid analgesics, including common cough and cold remedies and antidiarrheal preparations, may not work as effectively with Contrave (Naltrexone/Bupropion). If you require intermittent opioid treatment, it’s recommended to temporarily stop Contrave (Naltrexone/Bupropion) therapy.[9]
Always discuss with your doctor all the medications you’re taking to ensure that taking Contrave (Naltrexone/Bupropion) is safe and effective for you.
