Tofranil™ (imipramine hydrochloride) Tablet Sugar Coated, 50 mg

This information is intended for U.S. healthcare professionals only.


Tofranil™ (imipramine hydrochloride tablets USP) is indicated in:

  • Depression - For the relief of symptoms of depression. Endogenous depression is more likely to be alleviated than other depressive states. One to three weeks of treatment may be needed before optimal therapeutic effects are evident.
  • Childhood Enuresis - May be useful as temporary adjunctive therapy in reducing enuresis in children aged 6 years and older, after possible organic causes have been excluded by appropriate tests. In patients having daytime symptoms of frequency and urgency, examination should include voiding cystourethrography and cystoscopy, as necessary. The effectiveness of treatment may decrease with continued drug administration.


Suicidality and Antidepressant Drugs

Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of imipramine hydrochloride or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Imipramine hydrochloride is not approved for use in pediatric patients.


Tofranil is contraindicated:

  • with concomitant use of monoamine oxidase inhibiting compounds. Hyperpyretic crises or severe convulsive seizures may occur in patients receiving such combinations. The potentiation of adverse effects can be serious, or even fatal. When it is desired to substitute Tofranil in patients receiving a monoamine oxidase inhibitor, as long an interval should elapse as the clinical situation will allow, with a minimum of 14 days. Initial dosage should be low and increases should be gradual and cautiously prescribed.
  • during the acute recovery period after a myocardial infarction.
  • in patients with a known hypersensitivity to this compound should not be given the drug. The possibility of cross-sensitivity to other dibenzazepine compounds should be kept in mind.


  • All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases.
  • Families and caregivers of patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to healthcare providers. Such monitoring should include daily observation by families and caregivers.
  • 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. Hypomanic or manic episodes may occur, particularly in patients with cyclic disorders.
  • Extreme caution should be used in
    • patients with cardiovascular disease because of the possibility of conduction defects, arrhythmias, congestive heart failure, myocardial infarction, strokes, and tachycardia. These patients require cardiac surveillance at all dosage levels of the drug.
    • patients with increased intraocular pressure, history of urinary retention, or history of narrow-angle glaucoma because of the drug's anticholinergic properties.
    • hyperthyroid patients or those on thyroid medication because of the possibility of cardiovascular toxicity.
    • patients with a history of seizure disorder because this drug has been shown to lower the seizure threshold.
    • patients receiving guanethidine, clonidine, or similar agents, since Tofranil may block the pharmacologic effects of these drugs.
    • patients receiving methylphenidate hydrochloride. Since methylphenidate hydrochloride may inhibit the metabolism of Tofranil, downward dosage adjustment of imipramine hydrochloride may be required when given concomitantly with methylphenidate hydrochloride.
  • Since Tofranil may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as operating an automobile or machinery, the patient should be cautioned accordingly.
  • Tofranil may enhance the CNS depressant effects of alcohol or other CNS depressants. Therefore, it should be borne in mind that the dangers inherent in a suicide attempt or accidental overdosage with the drug may be increased for the patient who uses excessive amounts of alcohol.Deaths may occur from overdosage with this class of drugs.
  • Elderly patients and patients with cardiac disease or a prior history of cardiac disease are at special risk of developing the cardiac abnormalities associated with the use of Tofranil.
  • An activation of the psychosis may occasionally be observed in schizophrenic patients.
  • Concurrent administration of Tofranil with electroshock therapy may increase the hazards.
  • Patients taking imipramine hydrochloride should avoid excessive exposure to sunlight since there have been reports of photosensitization.
  • Both elevation and lowering of blood sugar levels have been reported with imipramine hydrochloride use.
  • Patients who develop a fever and a sore throat during therapy with imipramine hydrochloride should have leukocyte and differential blood counts performed. Tofranil should be discontinued if there is evidence of pathological neutrophil depression.
  • Prior to elective surgery, Tofranil should be discontinued for as long as the clinical situation will allow.


  • Serious adverse reactions may include clinical worsening of depression and suicidal ideation, hypotension, hypertension, arrhythmias, heart block, tachycardia, congestive heart failure, myocardial infarction, strokes, confusion, seizures, serotonin syndrome, and withdrawal symptoms with abrupt discontinuation of Tofranil including nausea, headache, and malaise.
  • Other adverse reactions may include anticholinergic effects (such as dry mouth, constipation, blurred vision, and urinary retention); gastrointestinal complaints; nausea; vomiting; anorexia; peculiar taste, anorexia; sleep disorders; and anxiety. See full prescribing information for full listing of adverse reactions.


  • The safety and effectiveness of the drug as temporary adjunctive therapy for nocturnal enuresis in pediatric patients less than 6 years of age has not been established. Safety and effectiveness in the pediatric population other than pediatric patients with nocturnal enuresis have not been established.
  • Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.
  • Tofranil should be used with caution in patients with significantly impaired renal or hepatic function.
