Paroxetine, propranolol
Paroxetine may increase the bradycardic effect of propranolol
Paroxetine, ranolazine [2] ---> SmPC of [2] of EMA
Ranolazine is partially metabolised by CYP2D6; therefore, inhibitors of this enzyme may increase plasma concentrations of ranolazine. No dosage adjustment necessary.
Paroxetine, risperidone [2] ---> SmPC of [2] of eMC
Paroxetine, strong CYP2D6 inhibitor, may increase the plasma concentrations of risperidone (narrow therapeutic index). Caution is recommended

Paroxetine, sertindole
The plasma concentration of sertindole is increased in patients concurrently taking potent CYP2D6 inhibitors; sertindole should therefore only be used concomitantly with CYP2D6 inhibitors with extreme caution.
Paroxetine, St. John's wort [2] ---> SmPC of [2] of eMC
As with other SSRIs, co-administration with serotonergic drugs may lead to an incidence of 5-HT associated effects (serotonin syndrome)

Selective serotonin reuptake inhibitors may reduce the activity of plasma cholinesterase, what may cause prolongation of neuromuscular blocking action of mivacurium and suxamethonium
Paroxetine, tamoxifen [2] ---> SmPC of [2] of eMC
Concomitant medications that inhibit CYP2D6 may lead to reduced concentrations of the active metabolite endoxifen. Therefore, potent inhibitors of CYP2D6 should whenever possible be avoided during tamoxifen treatment
Paroxetine, terfenadine
The CYP3A4 inhibition may increase the terfenadine plasma levels and prolong the QT interval (risk of life-threatening arrythmias). The combination is contraindicated
Paroxetine, tetrabenazine [2] ---> SmPC of [2] of eMC
Inhibitors of CYP2D6 may result in increased plasma concentrations of the active metabolite dihydrotetrabenazine, why they should only be combined with caution. A reduction of the tetrabenazine dose may be necessary.
Paroxetine, ticagrelor [2] ---> SmPC of [2] of EMA
Due to reports of cutaneous bleeding abnormalities with SSRIs, caution is advised when administering SSRIs with ticagrelor as this may increase the risk of bleeding.

The previous or concomitant treatment of SSRIs with trimipramine may increase the plasma levels of both antidepressants by substrate competition
Paroxetine, vortioxetine [2] ---> SmPC of [2] of EMA
Depending on individual patient response, a lower dose of vortioxetine may be considered if strong CYP2D6 inhibitor is added to vortioxetine treatment
CONTRAINDICATIONS of Paroxetine
- Known hypersensitivity to paroxetine or any of the excipients.
- Paroxetine is contraindicated in combination with monoamine oxidase inhibitors (MAOIs). In exceptional circumstances, linezolid (an antibiotic which is a reversible non-selective MAOI) can be given in combination with paroxetine provided that there are facilities for close observation of symptoms of serotonin syndrome and monitoring of blood pressure
- Treatment with paroxetine can be initiated:
- two weeks after discontinuation of an irreversible MAOI, or
- at least 24 hours after discontinuation of a reversible MAOI (e.g. moclobemide, linezolid, methylthioninium chloride (methylene blue; a preoperative visualising agent which is a reversible non-selective MAOI)).
- At least one week should elapse between discontinuation of paroxetine and initiation of therapy with any MAOI.
- Paroxetine should not be used in combination with thioridazine, because, as with other drugs which inhibit the hepatic enzyme CYP450 2D6, paroxetine can elevate plasma levels of thioridazine (see section 4.5 Interactions with other medical products and other forms of interaction). Administration of thioridazine alone can lead to QTc interval prolongation with associated serious ventricular arrhythmia such as torsades de pointes, and sudden death.
- Paroxetine should not be used in combination with pimozide
- Purified soya lecithin may contain peanut protein. The PhEur monograph does not contain a test for residual protein.

CONTRAINDICATIONS of Pimozide
- In common with several other neuroleptics, pimozide has been reported to prolong the QT interval. It is, therefore, contra-indicated in patients with a pre-existing congenital prolongation of QT, or with a history or family history of this syndrome, and in patients with a history of cardiac arrhythmias and a history of Torsades de pointes. Orap should not be used in the case of acquired long QT interval, such as that associated with the concomitant use of drugs known to prolong the QT interval, known uncorrected hypokalaemia or hypomagnesaemia, or clinically significant cardiac disorders (eg recent acute myocardial infarction, uncompensated heart failure, arrhythmias treated with class IA and III antiarrhythmic medicinal products) or clinically significant bradycardia.
- Orap is also contra-indicated in patients with severe central nervous system depression and in patients with a known hypersensitivity to pimozide or other diphenylbutyl-piperidine derivatives. It should not be used in patients with depression or Parkinson's syndrome.
- The concomitant use of orally or parenterally administered cytochrome P450 CYP 3A4 inhibiting drugs such as azole antimycotics, antiviral protease inhibitors, macrolide antibiotics and nefazodone is contra-indicated. The concomitant use of CYP 2D6 inhibiting drugs such as quinidine is also contra-indicated. The inhibition of either or both of these cytochrome P450 systems may result in the elevation of pimozide blood concentration and increase the possibility of QT-prolongation.
- Orap is contraindicated with concomitant use of serotonin uptake inhibitors such as sertraline, paroxetine, citalopram and escitalopram
