Does Contrave cause dry mouth?
Yes, and it is on the label rather than only in reports: dry mouth 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. Dry mouth is listed by the stimulant-based tablets here and it comes from the same nervous-system effect that raises heart rate and blunts appetite: less saliva. It is among the most common reactions on these labels and among the least dangerous, but it is not harmless, because saliva is what protects teeth. It does not follow the dose schedule, so it does not come and go with dose increases. What helps first: sipping water through the day rather than drinking a lot at once. It stops being ordinary at a specific line: dry mouth with a great deal of thirst and passing much more urine than usual, which is a diabetes picture rather than a side effect. Also mouth ulcers or white patches that do not clear.
What helps with dry mouth on Contrave?
- 1Sipping water through the day rather than drinking a lot at once.
- 2Sugar-free gum or lozenges, which prompt what saliva there is. Sugared ones on a dry mouth are how people get cavities fast.
- 3Telling the dentist you are taking this. Reduced saliva changes what a check-up should look for.
- 4Avoiding alcohol-based mouthwash, which dries further.
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 dry mouth on Contrave serious?
Dry mouth with a great deal of thirst and passing much more urine than usual, which is a diabetes picture rather than a side effect. Also mouth ulcers or white patches that do not clear.
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?
Dry mouth is on 3 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.
