What the label asks for
A reduced-calorie diet — and no high-fat meals with your dose
The label indication says Contrave is used in combination with a reduced-calorie diet and increased physical activity, to reduce excess body weight and maintain weight reduction long term. On top of that general framing sits one specific instruction: in clinical trials Contrave was administered with meals, but it should not be taken with a high-fat meal, because of the resulting significant increase in bupropion and naltrexone systemic exposure. That rule is not about calories — it is about drug levels.
What to prioritise
When your appetite is 50% of what it used to be, every bite has to earn its place. Here is the priority stack.
High-fat meals
Not with your doseThe label says a high-fat meal significantly increases how much bupropion and naltrexone reach the bloodstream, and lists avoiding high-fat meals among the measures that reduce seizure risk.
- CONTRAVE should not be taken with a high-fat meal
- The reason given is a significant increase in bupropion and naltrexone exposure
- Avoiding high-fat meals appears in the seizure-risk reduction list
- In clinical trials, Contrave was administered with meals
Alcohol
Minimise or avoidThe label reports rare neuropsychiatric events and reduced alcohol tolerance with bupropion, and separately treats abrupt withdrawal from heavy drinking as a seizure risk and a contraindication.
- Consumption of alcohol during treatment should be minimised or avoided
- Rare reports of neuropsychiatric events or reduced alcohol tolerance with bupropion
- Abrupt discontinuation of alcohol is a contraindication to Contrave
- If you drink heavily, talk to your provider before suddenly stopping
Habits that help vs habits that hurt
These patterns come up repeatedly in clinical guidance and community experience.
Prioritise these
- Take your tablets with ordinary meals if that helps you remember — the trials did
- Keep the tablets away from clearly high-fat meals, as the label instructs
- Follow the reduced-calorie diet and increased physical activity the indication describes
- Swallow the tablets whole, without cutting, chewing or crushing them
- Talk to your provider before suddenly stopping heavy alcohol use
- Tell any prescriber about Contrave before opioid-containing medicines are given
Watch out for
- Take Contrave with a high-fat meal — the label says not to, and ties it to seizure risk
- Take more than two tablets at one time, or more than four in a day
- Drink heavily during treatment: the label says to minimise or avoid alcohol
- Stop drinking abruptly without medical advice, given the seizure risk
- Double up after a missed dose — wait for the next scheduled one
- Assume opioid-containing cough or antidiarrhoeal remedies are fine
The high-fat meal trap
This is not a diet rule — it is a drug-level rule
It is easy to read "avoid high-fat meals" as ordinary weight-loss advice and file it with everything else. The label treats it very differently. It says Contrave should not be taken with a high-fat meal because of a resulting significant increase in bupropion and naltrexone systemic exposure, and it then lists avoiding high-fat meals alongside the other measures that reduce the risk of seizure: keeping the total daily dose within 360 mg of the bupropion component, splitting it into two daily doses, escalating gradually, never taking more than two tablets at one time, and waiting for the next scheduled dose if one is missed. The label reports the incidence of seizure with Contrave in clinical trials as about 0.1%, against 0% on placebo, and says the risk is dose-related. A high-fat meal effectively raises your dose.
Sample meal ideas
These are not prescriptions — they are starting points. Adapt to your preferences, culture, and dietary needs.
- Porridge or wholegrain toast
- Eggs with tomatoes and toast
- Yogurt with fruit
A fried breakfast is the classic high-fat meal — the label rules that out alongside your dose.
- A sandwich or wrap with salad
- Soup with bread
- A grain bowl with lean protein
Ordinary meals are fine. In the clinical trials, Contrave was administered with meals.
- Chicken or fish with vegetables
- A pasta dish with a lighter sauce
- Stir-fry with rice
Rich, creamy or deep-fried dinners are the ones to keep away from the evening tablet.
- Fried food and takeaways
- Creamy sauces and pastry
- Anything that reads as a heavy, fatty meal
The label does not define a fat threshold, so use judgement and ask your pharmacist if unsure.
