Before you take this type of medicine, be sure to tell your doctor if you:

  • Are nursing, pregnant, or plan to become pregnant
  • Take any prescription medications for other conditions, like blood pressure drugs, antidepressants, sedatives, or antipsychotics
  • Take any dietary supplements, herbal medicines, or over-the-counter medications
