Lofepramine reduces neuronal reuptake of monoamines, particularly noradrenaline, and enhances serotonergic transmission. This increases the availability of chemical messengers involved in mood regulation. Its active metabolite, desipramine, also contributes to its antidepressant effect.

lofepramine hydrochloride in pregnancy
The product information advises avoiding lofepramine during pregnancy unless there are compelling medical reasons because medicine-specific safety is not established. Independent UK pregnancy information states that tricyclic antidepressants as a class are not known to harm the baby, but exposure near delivery can cause temporary newborn withdrawal or adaptation symptoms. Discuss treatment with the prescriber when planning pregnancy or as soon as pregnancy is recognised; do not stop abruptly without advice.
lofepramine hydrochloride while breastfeeding
The product information advises against use while breastfeeding unless there are compelling medical reasons. UK specialist guidance says lofepramine may be used cautiously for a full-term, healthy infant, although imipramine or nortriptyline are preferred because direct evidence for lofepramine is absent. If used, monitor the infant for unusual drowsiness, poor feeding, inadequate weight gain, irritability, constipation or reduced wet nappies; seek specialist advice for premature or unwell infants.
lofepramine hydrochloride interactions
Check prescribed, over-the-counter and herbal products with a pharmacist or prescriber. Important interactions include:
Monoamine oxidase inhibitors
The combination is contraindicated because severe reactions may occur; a defined separation period is required when switching.
Amiodarone and other QT-prolonging medicines
May increase the risk of dangerous ventricular arrhythmias; amiodarone should be avoided.
Fluoxetine, fluvoxamine and other serotonergic antidepressants
May increase serotonergic effects, lofepramine exposure and seizure risk.
