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 it happens to everyone. 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. Most people see 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 first: fluid first, and enough salt with it. Both drop with intake and both cause this. 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.

How long does Contrave headache last?

What helps with headache on Contrave?

  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 boxed warning and main serious risks concern mood, seizures, opioid use and blood pressure. Its most common side effect is still nausea: in the trials 24% stopped because of an adverse event, against 12% on placebo, and nausea was the most common reason, at 6.3%. Anyone on long-term opioid treatment, including buprenorphine for addiction, cannot take it; for a short course of opioids it is paused, and lower opioid doses may be needed.

When is headache on Contrave serious?

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 behavior 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.

Would switching drugs help?

Headache is on 6 of the 13 FDA labels tracked here, so the other labels are worth reading before assuming a switch avoids it. What a switch does change is what you pay, and Contrave is $99 a month at the maintenance dose here.
