PRISTIQ (desvenlafaxine succinate) Contraindications

Contraindications

  • PRISTIQ must not be used concomitantly in patients taking monoamine oxidase inhibitors (MAOIs), including linezolid, an antibiotic, methylene blue, a dye used in certain surgeries, or in patients who have taken MAOIs within the preceding 14 days due to the risk of serious, sometimes fatal, drug interactions with selective serotonin reuptake inhibitor (SSRI) or serotonin norepinephrine reuptake inhibitor (SNRI) treatment or with other serotonergic drugs. These interactions have been associated with symptoms that include tremor, myoclonus, diaphoresis, nausea, vomiting, flushing, dizziness, hyperthermia with features resembling neuroleptic malignant syndrome, seizures, rigidity, autonomic instability with possible rapid fluctuations of vital signs, and mental status changes that include extreme agitation progressing to delirium and coma. Based on the half-life of desvenlafaxine succinate, at least 7 days should be allowed after stopping desvenlafaxine succinate and before starting an MAOI.
     
  • Hypersensitivity to desvenlafaxine succinate extended-release, venlafaxine hydrochloride or to any excipients in the desvenlafaxine formulation (see DOSAGE FORMS, COMPOSITION AND PACKAGING).
