Other Medications and dormirel

Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.

Do not take dormirel with the following medications, as their effects may be enhanced:

  • Epinephrine (for low blood pressure).
  • Medications that affect the heart, such as those used to treat arrhythmias, some antibiotics, certain antimalarial medications, certain antihistamines, certain medications used to reduce lipids (fat) in the blood, or certain neuroleptic agents (medications for treating mental disorders).
  • Medications that decrease the elimination of others, such as azole derivatives or macrolides, as they may increase the effect of dormirel.
  • Certain diuretics (medications that increase urine elimination).
  • Central nervous system inhibitors (e.g., barbiturates, hypnotics, sedatives, anxiolytics, opioid analgesics, antipsychotics, or procarbazine).
  • Antihypertensives (medications for high blood pressure) with a central nervous system effect, such as guanabenz, clonidine, or alpha-methyldopa.
  • Other anticholinergic medications, such as those used to treat depression or Parkinson's disease, monoamine oxidase inhibitors (medications for depression), neuroleptics (medications for treating mental disorders), atropine-like medications for treating spasms, or disopyramide (for certain heart problems).
  • If you are taking other medications that can cause ear toxicity, such as carboplatin or cisplatin (medications for cancer), chloroquine (a medication for malaria), or certain antibiotics (medications for infections) like erythromycin or injectable aminoglycosides, among others, dormirel may mask the toxic effects of these medications, so you should periodically review the condition of your ears.
