Please note: a valid prescription is required for all prescription medication.
Buy Contrave ER 8-90mg tablets online with a valid prescription and compare current listed pricing, available quantity details, and safety basics before ordering. Here you can match the selected naltrexone bupropion ER tablet listing to your prescription, check the 8 mg/90 mg strength, and review access factors such as cash-pay status and US delivery from Canada. Before checkout, confirm the product form, quantity, storage expectations, and key warnings with the information below.
Contrave ER is an extended-release prescription weight loss medication used with a reduced-calorie diet and increased physical activity for certain adults. It is not the same as a GLP-1 injection, and it should not be started, stopped, or combined with other medicines without clinician guidance.
Contrave ER 8-90mg Tablets Price and Available Options
Start by comparing the currently listed price against the selected strength, tablet count, and any option shown on the product selector. Contrave 120 tablets may represent a bottle quantity, not a promise about how long it will last, because the prescribed schedule can change during titration. Match the listing to the medicine name, release type, and strength written by your prescriber before placing an order.
Each tablet contains 8 mg of naltrexone hydrochloride and 90 mg of bupropion hydrochloride in an extended-release formulation. If different quantities or presentations appear as separate listings, compare them separately rather than assuming the same total contents, pill count, or ordering path. This matters because tablet strength and total quantity affect the selected product, while clinical instructions come from the prescriber.
If you are comparing Contrave price without insurance, focus on the cash-pay amount shown for the selected quantity and any checkout requirements attached to that option. Coverage status can change how an order is processed, but the safest product match still starts with the exact tablet strength and quantity on the prescription.
| Product detail | What to check before checkout |
|---|---|
| Form | Extended-release oral tablets |
| Strength | 8 mg naltrexone HCl and 90 mg bupropion HCl per tablet |
| Quantity | Confirm the listed tablet count, such as a 120-tablet listing when shown |
| Use path | Match to the prescriber’s written instructions, not a self-selected schedule |
Quick tip: Compare the selected quantity and strength before comparing totals across listings.
How to Buy Contrave ER Online
To order Contrave ER online, choose the correct product listing, confirm the quantity, and provide the requested customer and prescriber details during checkout. Keep the prescription information available, especially if the order details need to be matched against what your clinician prescribed. This step protects against choosing a tablet count or strength that looks similar but does not match the order.
Prescription details may be verified with your prescriber when needed. Supporting information may also be requested if the selected product, quantity, or account details require clarification. These checks are part of matching the prescription order to the selected product; they do not replace clinical guidance about whether this medicine is appropriate.
If the selected order uses US shipping from Canada, review the checkout information carefully before payment. Confirm the shipping address, contact information, and product selection in one pass so any follow-up questions can be handled without changing the medicine details. The practical value of this listing is comparison: current listed price, tablet strength, quantity, and access path can be reviewed in one place.
Prescription, Strength, and Quantity Details
Contrave ER tablets combine two active ingredients. Naltrexone is an opioid antagonist, a medicine that blocks opioid receptors, and bupropion is an antidepressant-class medicine that also affects appetite-related pathways. The extended-release tablet is designed to release medicine over time, so it should not be crushed, split, or chewed unless the official label or prescriber specifically says otherwise.
The 8 mg/90 mg strength identifies the amount of each active ingredient in one tablet. It does not describe an individual dosing schedule by itself. Many prescriptions involve a titration period, which means the number of tablets taken may change over time according to the clinician’s instructions. Because of that, the tablet count on a bottle should not be used to self-calculate treatment duration.
The Understanding Contrave Dosage resource can help you prepare non-urgent questions about tablet schedules, missed doses, and label terms. Use it to organize a discussion with your clinician, not to change the plan on your own.
Why it matters: The same active ingredients can appear in other products, but this ER combination has its own label.
What This Medicine Is Used For
Contrave weight loss medication is used as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in certain adults. The official indication includes adults with obesity, and some adults who are overweight and also have a weight-related condition such as high blood pressure, type 2 diabetes, or dyslipidemia. A clinician determines whether the medicine fits the person’s health profile.
This treatment is not an over-the-counter diet pill and is not used for sudden weight changes. It is also different from injectable GLP-1 medicines such as semaglutide products. Contrave tablets work through naltrexone and bupropion pathways, while GLP-1 medicines work through incretin hormone pathways and have different forms, dosing schedules, and warnings.
For product browsing, the Weight Management category groups prescribed options that may be compared by form and class. The Obesity and Overweight product lists can also help organize related listings without replacing clinical assessment.
Safety Points Before Ordering
Contrave ER carries important warnings because it contains bupropion. Antidepressant-class medicines can increase the risk of suicidal thoughts and behaviors in some younger people, and mood or behavior changes need prompt clinical attention. Report new agitation, worsening depression, panic symptoms, unusual mood changes, or thoughts of self-harm to a healthcare professional right away.
Do not use naltrexone bupropion tablets in several situations listed in the official prescribing information. Key contraindications include uncontrolled high blood pressure, seizure disorder, current or prior bulimia or anorexia nervosa, use of other bupropion-containing products, chronic opioid use, acute opioid withdrawal, abrupt discontinuation of alcohol or certain sedatives, MAOI use within the restricted window, pregnancy, or known hypersensitivity to the ingredients. These are safety exclusions, not ordinary side-effect precautions.
Common side effects can include nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea. Some people may also experience increased blood pressure or heart rate. Serious reactions are less common but can include seizures, severe allergic reactions, liver injury, angle-closure glaucoma, and neuropsychiatric symptoms. The Common And Rare Contrave Side Effects resource can help you identify symptoms to discuss with a clinician.
- Blood pressure: confirm monitoring plans if readings are elevated.
- Seizure risk: review past seizures, eating disorders, and interacting medicines.
- Mood changes: report new or worsening psychiatric symptoms promptly.
- Opioid exposure: disclose pain medicines, opioid treatment, or recent opioid use.
- Pregnancy: do not use this medicine during pregnancy.
Interactions, Monitoring, and Food Considerations
Before ordering, review current medicines with the prescriber and pharmacist. Important interactions can involve opioid pain medicines, medicines for opioid use disorder, monoamine oxidase inhibitors, other products that contain bupropion, alcohol, sedatives, seizure-threshold-lowering medicines, and some drugs affected by CYP2D6 metabolism. This includes certain antidepressants, antipsychotics, beta blockers, and antiarrhythmics.
High-fat meals are specifically relevant. The label advises that Contrave should not be taken with a high-fat meal because exposure to the active ingredients can increase. That does not mean one universal diet is required, but meal timing and food choices should follow the label and the clinician’s plan. Alcohol intake also deserves caution because bupropion may increase seizure risk in susceptible people.
Monitoring is part of safe use. Blood pressure and pulse may need checking before and during treatment, especially in people with hypertension or cardiovascular risk factors. People with diabetes who use insulin or insulin secretagogues may need glucose monitoring because weight loss and reduced food intake can affect blood sugar. These points should be reviewed before the selected product is matched to an order.
Storage, Handling, and Travel Basics
Contrave ER tablets are generally stored at room temperature according to label directions. Keep the bottle tightly closed, dry, and away from children and pets. Avoid storing tablets in bathrooms, cars, or other places where heat, moisture, or temperature swings may affect the medicine.
Unlike many injectable weight management products, these tablets are not typically handled as refrigerated medicines. Still, the package should be protected from moisture and physical damage during handling. If tablets arrive broken, discolored, or different from the expected product description, do not use them until the issue is clarified by an appropriate professional.
For travel, keep the medicine in its labeled container and carry enough information to show that it was prescribed. Do not combine tablets with other medicines in an unmarked container, especially because bupropion-containing products can look similar to unrelated tablets. If travel crosses borders, plan ahead so medicine details, prescriber information, and personal identification are consistent.
Compare Related Weight Management Options
Contrave is one option among prescription weight loss pills and injectable medicines. It may be considered when an oral tablet is clinically appropriate, but it is not interchangeable with GLP-1 receptor agonists, stimulants, lipase inhibitors, or diabetes medicines sometimes associated with weight change. Form, mechanism, monitoring needs, contraindications, and tolerability can differ substantially.
The Contrave Vs Wegovy comparison can help frame differences between an oral naltrexone bupropion ER product and a semaglutide injection. Use comparison content to prepare questions about class, safety profile, and route of administration. The final selection should come from a clinician who knows the full medication list and health history.
Some customers also compare naltrexone bupropion price, form, and access against other weight management therapies. Keep those comparisons practical. A lower listed total is not useful if the strength, quantity, contraindications, or prescribed product do not match the treatment plan.

Is Contrave ER the same as Ozempic?
No. Contrave ER is an oral extended-release tablet that combines naltrexone and bupropion. Ozempic is an injectable semaglutide product in the GLP-1 receptor agonist class and is approved for type 2 diabetes, though semaglutide products are also used in weight management under different brand names and labels. The medicines differ in mechanism, route, dosing schedule, warnings, and monitoring needs.
What foods should be avoided while taking naltrexone bupropion ER?
The official label advises not taking Contrave with a high-fat meal because it can increase exposure to naltrexone and bupropion. Alcohol also deserves caution because bupropion can increase seizure risk in susceptible people. There is no single required diet for every patient, but the medicine is intended to be used with a reduced-calorie diet and physical activity plan directed by a clinician.
What side effects should be monitored with Contrave ER?
Common side effects include nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea. More serious concerns include increased blood pressure or heart rate, seizures, severe allergic reactions, liver problems, angle-closure glaucoma, and mood or behavior changes. Because the product contains bupropion, new or worsening depression, agitation, panic, or suicidal thoughts need prompt medical attention.
What should I ask my clinician before starting Contrave ER?
Ask whether the medicine fits your weight-management plan, medical history, blood pressure status, seizure risk, pregnancy status, and current medication list. It is especially important to discuss opioid use, other bupropion-containing products, antidepressants, alcohol intake, diabetes medicines, and any history of eating disorders. Also ask how response will be assessed and what symptoms should trigger follow-up.
How long can it take to assess response to Contrave ER?
Response is assessed over time, not after a single dose. The label describes evaluating treatment after a period on the maintenance dose, and clinicians may stop therapy if an adequate response has not occurred. Individual timelines can differ because titration, tolerability, diet, physical activity, and other health factors matter. Do not change the schedule or continue beyond the clinician’s plan without guidance.
Can Contrave ER be used with opioid medicines?
Contrave contains naltrexone, which blocks opioid receptors. It is contraindicated in chronic opioid use, acute opioid withdrawal, and certain opioid treatment situations. Using opioids with naltrexone can reduce pain-control effects and may create serious risks if someone tries to overcome the blockade. Any opioid pain medicine, cough product, or treatment for opioid use disorder should be discussed before therapy starts.
