Does Contrave cause headaches?

Bottom line

Yes. Headache 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 cause headaches?

Yes, and it is on the label rather than only in reports: headache 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. The headache these labels list is usually the ordinary one that follows eating and drinking much less: less fluid, less salt, longer gaps between meals, and often less caffeine than the day before. It is listed on the label, and it is also the symptom most likely to have a cause you can fix in an afternoon. 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: fluid first, and enough salt with it. Both drop with intake and both cause this; not skipping meals entirely. Appetite suppression makes it easy to go a whole day, and a headache is often the first thing that notices; keeping caffeine steady rather than cutting it at the same time as everything else; watching whether it clusters after each dose increase, which is worth telling the prescriber before the next one. It stops being ordinary at a specific line: a headache that arrives suddenly and severely, or comes with fever, a stiff neck, visual change, weakness or confusion. Also any headache with a blood pressure reading well above your usual.

Why Contrave does this

The headache these labels list is usually the ordinary one that follows eating and drinking much less: less fluid, less salt, longer gaps between meals, and often less caffeine than the day before. It is listed on the label, and it is also the symptom most likely to have a cause you can fix in an afternoon.

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.

What actually helps

  1. 1Fluid first, and enough salt with it. Both drop with intake and both cause this.
  2. 2Not skipping meals entirely. Appetite suppression makes it easy to go a whole day, and a headache is often the first thing that notices.
  3. 3Keeping caffeine steady rather than cutting it at the same time as everything else.
  4. 4Watching whether it clusters after each dose increase, which is worth telling the prescriber before the next one.

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

A headache that arrives suddenly and severely, or comes with fever, a stiff neck, visual change, weakness or confusion. Also any headache with a blood pressure reading well above your usual.

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

Headache 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.
