- trimipramine
Interactions between your drugs
pseudoephedrine trimipramine
Applies to: Coldmist Jr (guaifenesin / pseudoephedrine) and trimipramine
GENERALLY AVOID: Tricyclic antidepressants (TCAs) may enhance the pressor response to sympathomimetic agents such as pseudoephedrine. The mechanism is TCA inhibition of norepinephrine reuptake in adrenergic neurons, resulting in increased stimulation of adrenergic receptors. This may increase the risk of adverse reactions such as hypertension, throbbing headache, tremor, palpitation, chest pain, and cardiac dysrhythmia.
MANAGEMENT: Sympathomimetic agents such as pseudoephedrine should preferably be avoided during therapy with tricyclic antidepressants. If concomitant use is necessary, caution is recommended and cardiovascular status including blood pressure, should be monitored closely.

Drug and food interactions
trimipramine food
Applies to: trimipramine
GENERALLY AVOID: Concomitant use of ethanol and a tricyclic antidepressant (TCA) may result altered TCA plasma levels and efficacy, and additive impairment of motor skills, especially driving skills. Acute ethanol ingestion may inhibit TCA metabolism, while chronic ingestion of large amounts of ethanol may induce hepatic TCA metabolism.
MANAGEMENT: Patients should be advised to avoid alcohol during TCA therapy. Alcoholics who have undergone detoxification should be monitored for decreased TCA efficacy. Dosage adjustments may be required.

pseudoephedrine food
Applies to: Coldmist Jr (guaifenesin / pseudoephedrine)
MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.
MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.
