Contrave (naltrexone/bupropion) dosage schedule
Tablets, twice a day. The FDA label below escalates it on a schedule, and the maintenance dose is 2 tablets twice a day, reached no earlier than week 4.
| When | Dose | What the label says about it |
|---|---|---|
| Week 1 | 1 tablet in the morning | — |
| Week 2 | 1 morning, 1 evening | — |
| Week 3 | 2 morning, 1 evening | — |
| Week 4 and on | 2 morning, 2 evening | The full dose: 32 mg naltrexone and 360 mg bupropion a day. |
Maximum dose: 32 mg / 360 mg a day. The label sets nothing above it.
Does the price change as the dose goes up?
The dose changes and the bill does not: Currax's CurAccess program charges $99 a month for Contrave, with no price by dose. The escalation takes three weeks, and the full dose of two tablets twice a day starts in week 4.
halfrx records Contrave (naltrexone/bupropion) at $99/mo at the maintenance dose, verified 2026-09-22.
What happens if I miss a dose?
Take the next dose at the usual time rather than doubling up. Do not take it with a high-fat meal at any point in the schedule.

Questions
- How long does it take to reach the maintenance dose of Contrave?
- At the fastest the label allows, week 4. Each step has to be held for its full interval before the next one, and a step can be repeated if the current dose is not tolerated — so the real answer is usually longer than the chart, never shorter.
Every dose and interval on this page is from FDA prescribing information for Contrave (naltrexone/bupropion) , the version published 2025-11-17. Nothing here is a recommendation: the dose you take is the one your prescriber sets, and the schedule is often slowed deliberately for tolerability.
