How we grade severity & evidence

Severity levels

  • Contraindicated: These should generally not be used together.
  • Major: Potentially serious — often needs a change or close monitoring.
  • Moderate: Can be significant — usually manageable with monitoring.
  • Minor: Usually limited clinical impact.

Evidence grades

  • Established: Well documented — supported by controlled studies or strong clinical data.
  • Probable: Good supporting evidence, though not definitively proven.
  • Suspected: Some evidence suggests this interaction, but it is not well established.
  • Possible: Limited or conflicting evidence; the interaction may occur.
  • Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.

Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.

Of 633 documented Buprenorphine interactions, 601 are rated major — including this one.

The Bottom Line
Combining bromopride and buprenorphine can add up their sedating effects, so the guidance is to avoid using them together; check with your pharmacist or doctor before making any changes.

Bromopride is a medicine for nausea and stomach problems, and it can make you feel drowsy. Buprenorphine (found in Belbuca, BuTrans, Sublocade, and others) is an opioid used for pain or for treating opioid dependence, and it can also make you sleepy. Taken together, these two can add up and make you more drowsy than either one alone. You might feel very sleepy, dizzy, or slower to react.

This warning is based on how these drugs are expected to behave rather than strong studies, but the caution is real. Please don't stop or change anything on your own. Talk with your pharmacist or doctor, who can manage this safely for you.

Effect: Additive CNS depression (potentiation of sedative effects) with concomitant bromopride and buprenorphine.

Mechanism: Pharmacodynamic. Both agents independently produce sedation (bromopride, a dopamine antagonist antiemetic; buprenorphine, a partial mu-opioid agonist). This is additive PD, not a metabolic/PK interaction. Neither is a prodrug relevant here.

Evidence: Theoretical. Onset: unspecified. Severity: major.

  • Documented guidance is to avoid concomitant use.
  • If co-prescribed, monitor for excess sedation, dizziness, and respiratory depression; consider dose individualization and closer observation.

What happens

Potentiation of sedative effects

Interaction Deep Dive

Using bromopride together with opioid analgesics can lead to enhanced sedative effects. Concurrent administration should be avoided1.

How to manage this interaction

The documented guidance is to avoid using bromopride and buprenorphine together because their sedative effects can add up.

  • Keep taking both exactly as prescribed for now, and do not stop either on your own.
  • Ask your pharmacist or prescriber whether an alternative anti-nausea medicine could be used instead.
  • If they decide to continue both, doses may need to be adjusted and individualized by your care team, and they may monitor you more closely.
  • Watch for strong drowsiness, dizziness, confusion, or slowed breathing, and seek help if these occur.

Management is individual — confirm any change with your pharmacist or prescriber.
