Triavil is used to treat depression occurring with other mental/mood disorders (such as anxiety, agitation, schizophrenia). Triavil is a combination of a tricyclic antidepressant (amitriptyline) and an antipsychotic medication (perphenazine). Together, they restore the balance of certain natural chemicals in the brain (neurotransmitters such as dopamine, norepinephrine, and serotonin). Triavil helps you to have a better mood and sense of well-being, think more clearly, and feel less nervous, so that you can take part in everyday life.
Antidepressant medications are used to treat a variety of conditions, including depression and other mental/mood disorders. These medications can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. It is very important to talk with the doctor about the risks and benefits of antidepressant medication (especially for people younger than 25), even if treatment is not for a mental/mood condition. Tell the doctor right away if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed. There may be a slightly increased risk of serious, possibly fatal side effects (such as stroke, heart failure, fast/irregular heartbeat, pneumonia) when Triavil is used by older adults with dementia. Triavil is not approved for the treatment of dementia-related behavior problems. Discuss the risks and benefits of Triavil, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor.
How to Use Triavil
Read the Medication Guide provided by your pharmacist before you start using Triavil and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take Triavil by mouth with or without food as directed by your doctor, usually 1 to 4 times daily. If you take it only once a day, take it at bedtime to help reduce daytime sleepiness. The Dosage of Triavil is based on your medical condition and response to treatment. Your doctor may direct you to take a low dose at first, gradually increasing the dose to lower the chance of side effects (such as drowsiness, dry mouth, muscle spasms). Follow your doctor's directions carefully. Take Triavil regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. Do not increase your dose or take Triavil more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase. Do not stop taking Triavil without consulting your doctor. Your condition may become worse when the drug is suddenly stopped. Muscle aches, headaches, and trouble sleeping may also occur. To prevent these symptoms while you are stopping treatment with Triavil, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details. Report any new or worsening symptoms right away. Triavil may not work right away. You may see some benefit within a week. However, it may take up to 4 weeks before you see the full effect. Tell your doctor if your condition lasts or gets worse (such as increased anxiety, your feelings of sadness get worse, or you have thoughts of suicide).
Before taking amitriptyline with perphenazine, tell your doctor or pharmacist if you are allergic to it; or to other tricyclic antidepressants (such as nortriptyline); or to other phenothiazines (such as chlorpromazine, fluphenazine); or if you have any other allergies. Triavil may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using Triavil, tell your doctor or pharmacist your medical history,bleeding problems, decreased bone marrow function, breathing problems (such as asthma, emphysema), liver problems, low blood pressure, recent heart attack, breast cancer, problems urinating (such as due to enlarged prostate), overactive thyroid (hyperthyroidism), personal or family history of glaucoma (angle-closure type), personal or family history of bipolar disorder, alcohol/substance abuse, family history of suicide, seizures, diabetes, conditions that may increase your risk of seizures (such as head injury, drug/alcohol withdrawal), a certain severe reaction to other medications (neuroleptic malignant syndrome), a certain adrenal gland tumor (pheochromocytoma), restless legs syndrome, Parkinson's disease. Perphenazine/amitriptyline may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using perphenazine/amitriptyline,certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death). Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, vomiting, or eating disorders (such as bulimia). Talk to your doctor about using perphenazine/amitriptyline safely. Triavil may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis). Before having any surgery, procedure, or imaging (such as X-ray, CT-scan), tell your doctor or dentist about Triavil and all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Triavil may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness. Caution is advised during hot weather because the perphenazine in Triavil can reduce sweating, increasing your risk for a severe reaction to too much heat (heatstroke). Drink plenty of fluids. Avoid strenuous exercise in hot weather. If you become overheated, promptly seek cooler shelter and/or stop exercising. Get medical help right away if your body temperature is above normal or if you have mental/mood changes, headache, or dizziness. Avoid exposure to certain chemicals used in gardening (organic phosphate insecticides). Get medical help right away if you are exposed to garden chemicals and have an unusual headache, heavy sweating, or difficulty breathing. If you have diabetes, Triavil may increase your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms such as increased thirst/urination. Your doctor may need to adjust your diabetes medication, exercise program, or diet. Children may be more sensitive to the side effects of Triavil, especially uncontrolled movements. Older adults may be more sensitive to the side effects of Triavil, especially dizziness, lightheadedness, drowsiness, confusion, bleeding, constipation, difficulty urinating, uncontrolled movements, and QT prolongation (see above). Dizziness, lightheadedness, drowsiness, and confusion can increase the risk of falling. During pregnancy, Triavil should be used only when clearly needed. Babies born to mothers who have used Triavil during the last 3 months of pregnancy may rarely develop symptoms including muscle stiffness or shakiness, drowsiness, feeding/breathing difficulties, or constant crying. If you notice any of these symptoms in your newborn especially during their first month, tell the doctor right away. Since untreated mental/mood problems (such as depression, schizophrenia) can be a serious condition, do not stop taking Triavil unless directed by your doctor. If you are planning pregnancy, become pregnant, or think you may be pregnant, immediately discuss with your doctor the benefits and risks of using Triavil during pregnancy. Triavil passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding.
If you miss a dose of Triavil, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up.
See also Precautions section. Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.anticholinergic/antispasmodic medications (such as belladonna alkaloids, dicyclomine, scopolamine), certain antihypertensive medications (such as clonidine, guanabenz, methyldopa), other drugs that can cause bleeding/bruising (including antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen/naproxen, blood thinners such as dabigatran/warfarin), disulfiram, levodopa, lithium, thyroid supplements. Taking MAO inhibitors with Triavil may cause a serious (possibly fatal) drug interaction. Avoid taking MAO inhibitors (isocarboxazid, linezolid, metaxalone, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with Triavil. Most MAO inhibitors should also not be taken for two weeks before and after treatment with Triavil. Ask your doctor when to start or stop taking Triavil. Other medications can affect the removal of perphenazine/amitriptyline from your body, which may affect how Triavil works. Examples include cimetidine, azole antifungals (such as ketoconazole, itraconazole), drugs to treat irregular heartbeat (such as amiodarone, flecainide, propafenone, quinidine), macrolide antibiotics (such as erythromycin), rifamycins (such as rifabutin), anti-HIV drugs (such as fosamprenavir), ritonavir, SSRI antidepressants (such as fluoxetine, paroxetine), St. John's wort, among others. Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine). Many drugs besides perphenazine/amitriptyline may affect the heart rhythm (QT prolongation). Examples include amiodarone, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), among others. Check the labels on all your medicines (such as antacids, allergy, or cough-and-cold products) because they may contain cimetidine, decongestants, or ingredients that cause drowsiness. Ask your pharmacist about using those products safely. Aspirin can increase the risk of bleeding when used with Triavil. However, if your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually 81-162 milligrams a day), you should continue taking it unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details. Amitriptyline is very similar to nortriptyline. Do not use medications containing nortriptyline while using amitriptyline.
