Key Reminders

When starting a new medication, it is always important to share this information with your doctor and pharmacist.  While it may be safe with one medication, others may become toxic or less effective. They can provide more information regarding potentially harmful combinations and how to manage them.  For example, did you know these combinations could be dangerous if not carefully managed?

  • Lithium with NSAIDs (ibuprofen, naproxen) or certain blood pressure medications (lisinopril)
  • Clozapine and cigarette smoking
  • Benzodiazepine anti-anxiety medications (alprazolam, lorazepam) and opioid pain medications (hydrocodone, oxycodone, morphine)
  • Antacids and certain antipsychotics (chlorpromazine, fluphenazine)
