Nausea and vomiting are among the most distressing withdrawal symptoms — several legitimate medication options exist to help.
Common options a doctor might prescribe or recommend:
- Ondansetron (Zofran) — a commonly used prescription anti-nausea medication
- Promethazine — another prescription option, though it carries its own sedation effect worth discussing given other withdrawal symptoms
- Over-the-counter options (like bismuth subsalicylate for mild symptoms)
What to discuss with a doctor before choosing one: Any other medications you’re taking (some anti-nausea medications interact with other withdrawal management medications or have their own QT-prolongation considerations, similar to the methadone concern) [link to QT prolongation article], and whether oral medication is realistic if vomiting is severe enough that you can’t keep pills down.
Why treating this matters beyond comfort: Uncontrolled nausea and vomiting contribute directly to the dehydration risk that’s the most significant genuine medical concern during opioid withdrawal itself. hydration article
When medication isn’t enough: If vomiting persists despite anti-nausea treatment and you can’t stay hydrated, that’s a reason to seek medical care rather than continue managing it at home. [“when to go to the ER” article]
