Does Contrave keep you awake?
Bottom line
Yes. Insomnia is listed among the common adverse reactions on Contrave's own FDA label, published 2025-11-17. It clusters in the days after each dose increase. Contrave steps up on a published schedule that reaches the maintenance dose at week 4, so the pattern most people see is a few rough days after each step and a settling in between — not one long stretch. Once you are at 2 tablets twice a day and no longer stepping up, the trigger stops recurring.
No clinician has reviewed this page. Every clinical statement on it is drawn from the FDA label or the trial cited beside it, and every price carries the date it was verified — but that is sourcing, not medical review, and the two are not the same thing.

Does Contrave keep you awake?
Yes, and it is on the label rather than only in reports: insomnia appears among the common adverse reactions in Contrave's FDA prescribing information, published 2025-11-17. Listed means it was seen often enough in the trials to be printed, not that everyone gets it. Every drug on this site that lists insomnia is a stimulant or contains one, and the wakefulness is the same pharmacology that suppresses the appetite — not a separate effect that happens to come along with it. That is why the time of day you take it matters more here than for any other symptom on this list, and why the label says when to take it rather than leaving it to preference. It clusters in the days after each dose increase. Contrave steps up on a published schedule that reaches the maintenance dose at week 4, so the pattern most people see is a few rough days after each step and a settling in between — not one long stretch. Once you are at 2 tablets twice a day and no longer stepping up, the trigger stops recurring. What helps, in the order worth trying: taking it in the morning, and not later than the label says. The evening dose is the commonest single cause and the label is explicit about it; keeping caffeine to the first half of the day, since it is additive with the drug rather than separate from it; telling the prescriber early. Dose timing and dose size are both adjustable, and sleep loss is a reason people abandon these drugs rather than a price of taking them. It stops being ordinary at a specific line: insomnia with a racing or irregular heartbeat, agitation, or any change in mood — low mood, unusual irritability, or thoughts of harming yourself. Mood change is not a wait-and-see symptom on this class of drug; where this page shows a boxed warning above, that warning is about exactly this.
Why Contrave does this
Every drug on this site that lists insomnia is a stimulant or contains one, and the wakefulness is the same pharmacology that suppresses the appetite — not a separate effect that happens to come along with it. That is why the time of day you take it matters more here than for any other symptom on this list, and why the label says when to take it rather than leaving it to preference.
When it happens, against Contrave's own schedule
Tablets, twice a day. Each row is a step up, and the days after each one are when this tends to arrive.
| Weeks | Dose |
|---|---|
| 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 |
What actually helps
- 1Taking it in the morning, and not later than the label says. The evening dose is the commonest single cause and the label is explicit about it.
- 2Keeping caffeine to the first half of the day, since it is additive with the drug rather than separate from it.
- 3Telling the prescriber early. Dose timing and dose size are both adjustable, and sleep loss is a reason people abandon these drugs rather than a price of taking them.
This is not a GLP-1: it is naltrexone plus bupropion, and its risks are neurological and cardiovascular rather than gastrointestinal. Anyone taking an opioid, including buprenorphine for addiction, cannot take it at all.
When to stop reading and call someone
Insomnia with a racing or irregular heartbeat, agitation, or any change in mood — low mood, unusual irritability, or thoughts of harming yourself. Mood change is not a wait-and-see symptom on this class of drug; where this page shows a boxed warning above, that warning is about exactly this.
Separately, Contrave carries a boxed warning. Bupropion raises the risk of suicidal thoughts and behaviour in children, adolescents and young adults. The label carries that as a boxed warning and tells prescribers to watch for mood changes, particularly in the first months and after any dose change.

If you are thinking of switching
Insomnia is on the label of most drugs in this class, so a switch is not a reliable way out of it. What a switch does change is what you pay, and Contrave is $99 a month at the maintenance dose here.
