Depression

100-200 mg PO qHS or divided q12hr

Up to 300 mg/day in severely ill

Renal Impairment

Supplemental dose not necessary in peritoneal or hemodialysis

Other Indications & Uses

Off-label: Postherpetic neuralgia, vulvodynia, eating disorder

Dosing considerations

Initial therapy may be administered in divided doses or a single daily dose

Dosage should be initiated at a lower level and increased according to tolerance and clinical response

Maintenance therapy may be given on a once-daily schedule for patient convenience and compliance

Treatment of patients requiring as much as 300 mg should generally be initiated in hospitals, where regular visits by the physician, skilled nursing care, and frequent electrocardiograms (ECGs) are available

The best available evidence of impending toxicity from very high doses is prolongation of the QRS or QT intervals on the ECG

Clinical symptoms of intolerance, especially drowsiness, dizziness, and postural hypotension, should also alert the physician to the need for reduction in dosage

            Warnings

            Black Box Warnings

            In short-term studies, antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults (<24 years) taking antidepressants for major depressive disorders and other psychiatric illnesses. This increase was not seen in patients aged >24 years. A slight decrease in suicidal thinking was seen in adults >65 years. In children and young adults, risks must be weighed against the benefits of taking antidepressants. Patients should be monitored closely for changes in behavior, clinical worsening, and suicidal tendencies. This should be done during initial 1-2 months of therapy and dosage adjustments. The patient’s family should communicate any abrupt changes in behavior to the healthcare provider

            Worsening behavior and suicidal tendencies that are not part of the presenting symptoms may require discontinuation of therapy

            This drug is not approved for use in pediatric patients

            Contraindications

            Hypersensitivity

            Acute recovery post-MI

            Within 14 days of taking MAO inhibitor

            Cautions

            Use caution in BPH and respiratory impairment

            Risk of anticholinergic side effects

            Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects; other reported clinical experience has not identified differences in responses between the elderly and younger patients

            This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function; because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function

            Use caution in patients with cardiovascular disease, because of possibility of conduction defects, arrhythmias, tachycardias, strokes, and acute myocardial infarction

            Caution in patients who have a family history of sudden death, cardiac dysrhythmias, or cardiac conduction disturbances

            Use caution in patients with a history of urinary retention or glaucoma, because of the anticholinergic properties of the drug

            Caution in patients with thyroid disease or those taking thyroid medication, because of possibility of cardiovascular toxicity, including arrhythmias

            Caution in patients with a history of seizure disorder, because this drug has been shown to lower seizure threshold; seizures precede cardiac dysrhythmias and death in some patients

            The pupillary dilation that occurs following use of many antidepressant drugs may trigger an angle-closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy

            The patient should be cautioned that this drug may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery

            Coadministration with MAO inhibitors

            • Risk of serotonin syndrome when coadministered within 14 days of MAOIs, or coadministered with other strong serotonergic drugs (eg, SNRIs, SSRIs)
            • Starting desipramine in a patient who is being treated with linezolid or IV methylene blue is contraindicated because of an increased risk of serotonin syndrome
            • If linezolid or IV methylene blue must be administered, discontinue desipramine immediately and monitor for CNS toxicity; may resume clomipramine 24 hr after last linezolid or methylene blue dose or after 2 weeks of monitoring, whichever comes first

            Clinical worsening and suicide risk

            • Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs
            • Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide; there has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment
            • Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (selective serotonin reuptake inhibitors [SSRIs] and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) with major depressive disorder (MDD) and other psychiatric disorders
            • Short-term studies did not show an increase in risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older
            • It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression
            • Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient's presenting symptoms
            • Prescriptions should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce risk of overdose

            Bipolar disorder

            • A major depressive episode may be the initial presentation of bipolar disorder; it is generally believed (though not established in controlled trials) that treating such an episode with an antidepressant alone may increase likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder
            • Whether any of the depressive symptoms represent a conversion is unknown; however, prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression; the drug is not approved for use in treating bipolar depression

            Serotonin syndrome

            • The development of a potentially life-threatening serotonin syndrome has been reported with serotonin-norepinephrine reuptake inhibitors (SNRIs) and SSRIs alone but particularly with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John’s Wort) and with drugs that impair metabolism of serotonin (in particular, MAOIs both those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue)
            • Serotonin syndrome symptoms may include mental status changes (eg, agitation, hallucinations, delirium, and coma), autonomic instability (eg, tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular changes (eg, tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (eg, nausea, vomiting, diarrhea); patients should be monitored for the emergence of serotonin syndrome

            Drug interaction overview

            • This drug is capable of blocking antihypertensive effect of guanethidine and similarly acting compounds
            • In patients who may use alcohol excessively, the potentiation may increase the danger inherent in any suicide attempt or overdosage

            Pregnancy & Lactation

            Pregnancy

            There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy

            Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at http://womensmentalhealth.org/clinical-and-research­programs/pregnancyregistry/antidepressants

            Safe use during pregnancy has not been established; therefore, if it is to be given to pregnant patients or women of childbearing potential, the possible benefits must be weighed against possible hazards to mother and child

            Animal reproductive studies have been inconclusive

            Lactation

            Safe use during lactation has not been established; therefore, if it is to be given to pregnant patients, nursing mothers, or women of childbearing potential, the possible benefits must be weighed against possible hazards to mother and child

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            COMMON BRAND NAME(S): Norpramin

            WARNING: 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.

            USES: Desipramine is used to treat depression. This medication may improve your mood, sleep, appetite, and energy level and may help restore your interest in daily living. This medication belongs to a class of medications called tricyclic antidepressants. It works by restoring the balance of a certain natural substance (norepinephrine) in the brain.This drug is not recommended for use in children younger than 18 years due to risk of serious side effects.

            HOW TO USE: Read the Medication Guide provided by your pharmacist before you start taking desipramine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth with or without food as directed by your doctor, usually 1 to 3 times daily. The dosage is based on your medical condition and response to treatment. Your doctor may start you at a low dose and gradually increase your dose. This medication may make you sleepy or wakeful. Depending on how this medication affects you, your doctor may direct you to take the entire dose once daily either in the morning or at bedtime.Follow your doctor's instructions carefully.

Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: breathing problems (such as asthma, chronic bronchitis), personal or family history of glaucoma (angle-closure type), diabetes, eating disorders (such as bulimia), heart problems (such as arrhythmias, coronary artery disease, heart attack), liver problems, kidney problems, personal or family history of other mental/mood conditions (such as bipolar disorder, schizophrenia), seizures, overactive thyroid (hyperthyroidism), trouble urinating (such as due to enlarged prostate), any condition that may increase your risk of seizures (including alcohol/sedative dependency, use of electroconvulsive therapy, brain injury/disease such as stroke), certain types of tumors (such as pheochromocytoma, neuroblastoma).Desipramine 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 desipramine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: 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, or vomiting. Talk to your doctor about using desipramine safely.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).This drug may make you dizzy or drowsy or blur your vision.

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.Older adults may be more sensitive to the side effects of this drug, especially dizziness (more likely when standing up), drowsiness, constipation, trouble urinating, mental/mood changes (such as confusion, agitation) and heart effects such as QT prolongation (see above). Dizziness, drowsiness, and confusion can increase the risk of falling.During pregnancy, this medication should be used only when clearly needed. Infants born to mothers who have taken similar medications during pregnancy may have symptoms such as trouble urinating, prolonged sleepiness, shaking, and seizures. Discuss the risks and benefits with your doctor.Since untreated mental/mood problems (such as depression, panic disorder) can be a serious condition, do not stop taking this medication unless directed by your doctor.

            DRUG INTERACTIONS: 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.Some products that may interact with this drug include: disopyramide, certain drugs for high blood pressure (such as clonidine, guanadrel, guanethidine), digoxin, thyroid supplements, valproic acid.Taking MAO inhibitors with this medication 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 this medication. Most MAO inhibitors should also not be taken for two weeks before and after treatment with this medication. Ask your doctor when to start or stop taking this medication.The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.Other medications can affect the removal of desipramine from your body, which may affect how desipramine works. Examples include barbiturates (such as phenobarbital), cimetidine, haloperidol, certain drugs for heart rhythm (such as flecainide, propafenone), halofantrine, HIV protease inhibitors (such as fosamprenavir), phenothiazines (such as thioridazine), pimozide, certain anti-seizure drugs (such as phenytoin), antidepressants (such as trazodone), among others.Cigarette smoking decreases blood levels of this medication. Tell your doctor if you smoke or if you have recently stopped smoking.Many drugs besides desipramine may affect the heart rhythm (QT prolongation in the EKG), including amiodarone, dofetilide, pimozide, procainamide, quinidine, sotalol, sparfloxacin, macrolide antibiotics (such as erythromycin), among others. Before using desipramine, report all medications you are currently using to your doctor or pharmacist.Tell your doctor or pharmacist if you are taking other products that cause drowsiness including alcohol, marijuana (cannabis), antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), and opioid pain relievers (such as codeine, hydrocodone).Check the labels on all your medicines (such as cough-and-cold products) because they may contain drowsiness-containing ingredients or decongestants that could increase your heart rate or blood pressure. Ask your pharmacist about the safe use of those products.Desipramine is very similar to imipramine. Do not take medications containing imipramine while using desipramine.
