Medicines that can react with this one.

Together they raise the risk of serotonin syndrome and seizures, and tramadol works less well.
Paroxetine raises aripiprazole levels; the dose may need to be lowered.
Paroxetine blocks the change of codeine into its active form, so pain relief may be poor.
Paroxetine raises risperidone levels and its side effects.
The combination can rarely cause serotonin syndrome.
