FLUOXETINE in Prozac
may interact with DEXTROMETHORPHAN in Robitussin Cough
Although there is limited evidence for this potential interaction, unusual side effects such as visual hallucinations or serotonin syndrome (elevated blood pressure, tremor, alterations in mental status, irritability and agitation, or irregular involuntary muscle contractions) may occur when fluoxetine and dextromethorphan are taken together. To avoid this potential interaction, you may want to use a cough suppressant other than dextromethorphan. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
This interaction is poorly documented and is considered moderate in severity.
