Precautions

Do not use this medication if you are allergic to amitriptyline (Elavil) or perphenazine (Trilafon), or if you have:

  • liver damage;
  • a blood cell disorder (such as anemia);

Serious, life-threatening side effects can occur if you take amitriptyline and perphenazine before the MAO inhibitor has cleared from your body.

  • glaucoma;
  • problems with urination;
  • bipolar disorder (manic-depression), schizophrenia or other mental illness;
  • history of drug or alcohol addiction;
  • history of suicidal thoughts or behavior; or
  • history of breast cancer.

If you have any of these conditions, you may not be able to use amitriptyline and perphenazine, or you may need a dosage adjustment or special tests during treatment.

You may have thoughts about suicide when you first start taking an antidepressant, especially if you are younger than 24 years old. Tell your doctor if you have worsening symptoms of depression or suicidal thoughts during the first several weeks of treatment, or whenever your dose is changed.

Your family or other caregivers should also be alert to changes in your mood or symptoms. Your doctor will need to check you at regular visits for at least the first 12 weeks of treatment.
