Precautions and warnings
Imipramine should be used cautiously and with close physician supervision in people, especially the elderly, who have benign prostatic hypertrophy, urinary retention, and glaucoma, especially angle-closure glaucoma. The sedative effect is increased when imipramine is taken with other central nervous system depressants, such as alcoholic beverages, sleeping medications, other sedatives, or antihistamines. Imipramine may increase heart rate and stress on the heart. It may be dangerous for people with cardiovascular disease, especially those who have recently had a heart attack, to take this drug or other antidepressants in the same pharmacological class. Older people and persons with a history of heart disease may develop heart arrhythmias, heart conduction abnormalities, congestive heart failure, heart attack, abnormally rapid heart rates and strokes. Until a therapeutic dosage has been determined, people starting imipramine should be closely watched for signs of suicide. The risk of suicide is increased when imipramine is taken in overdose or combined with alcohol. Manic episodes and the emergence of symptoms of pre-existing psychotic states have been reported when imipramine therapy is started.
The most frequent of side effects are dry mouth, constipation, urinary retention, increased heart rate, sedation, irritability, dizziness, and decreased coordination. Dry mouth, if severe to the point of causing difficulty speaking or swallowing, may be managed by dosage reduction or temporary discontinuation of the drug. Imipramine usage has been linked to both increases and decreases in blood pressure and heart rate. Heart attacks, congestive heart failure, and strokes have been reported. Confusion, disorientation, delusions, insomnia, and anxiety have also been reported as side effects in a small percentage of people taking imipramine. Problems associated with the skin (loss of sensation, numbness and tingling, rashes, spots, itching and puffiness), seizures, and ringing in the ears have also been reported. Nausea, vomiting, loss of appetite, diarrhea, and abdominal cramping are all side effects associated with imipramine usage in a small number of people.
Increased plasma levels and effects with quinidine, cimetidine, SSRIs, propafenone, flecainide. Reduced plasma levels with barbiturates, phenytoin. May increase effects of anticholinergic drugs. Severe orthostatic hypotension with altretamine. Causes drowsiness and impaired performance in combination with alcohol.
Potentially Fatal: Severe hypertension with adrenaline, noradrenaline and methylphenidate. Reduces hypotensive effects of guanethidine, bethanidine, debrisoquine, bretylium, methyldopa and clonidine. Possible serotonin syndrome with MAOIs, separate admin by 3 wk.
Imipramine should not be given in conjunction with, or within 14 days of treatment with a MAO inhibitor. Combined therapy of this type could lead to the appearance of serious interactions such as hypertensive crises, hyperactivity, hyperpyrexia, spasticity, severe convulsions or coma and death may occur. Imipramine is contraindicated in patients with existing severe hepatic or renal damage, and those with a history of blood dyscrasias. Imipramine is contraindicated in patients who have shown hypersensitivity to the drug or hypersensitivity to tricyclic antidepressants belonging to the dibenzazepine group. Imipramine is contraindicated for use during the acute recovery phase following a myocardial infarction. It should not be used in patients with convulsive disorders or glaucoma.
Mode of actions
Imipramine inhibits noradrenaline re-uptake and, to a lesser extent, that of serotonin.
