You should not use Pamelor if:

  • you are allergic to Pamelor or similar medicines (amitriptyline, amoxapine, clomipramine, desipramine, doxepin, imipramine, protriptyline, trimipramine);
  • you are allergic to certain seizure medications (carbamazepine, eslicarbazepine, oxcarbazepine, rufinamide); or

Tell your doctor if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or to prevent nausea and vomiting. An interaction with Pamelor could lead to a serious condition called serotonin syndrome.
