Before Using
Drug information provided by: Merative, Micromedex®
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Certain side effects, such as muscle spasms of the face, neck, and back, tic-like or twitching movements, inability to move the eyes, twisting of the body, or weakness of the arms and legs, are more likely to occur in children, who are usually more sensitive than adults to some of the side effects of perphenazine and amitriptyline combination.
The perphenazine and amitriptyline combination must be used with caution in children with depression. Studies have shown occurrences of children thinking about suicide or attempting suicide in clinical trials for this medicine. More study is needed to be sure the perphenazine and amitriptyline combination is safe and effective in children
Geriatric
Confusion, vision problems, dizziness or fainting, drowsiness, dryness of mouth, constipation, problems in urinating, trembling of the hands and fingers, and symptoms of tardive dyskinesia (such as uncontrolled movements of the mouth, tongue, jaw, arms, and/or legs) are especially likely to occur in elderly patients. Older patients are usually more sensitive than younger adults to the effects of perphenazine and amitriptyline combination.
Breastfeeding
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
