- Certain other antidepressants and antipsychotics: may increase sedation or raise amitriptyline levels.
- Anticholinergic drugs including some antihistamines and motion sickness preparations: additive effects can cause pronounced dry mouth, constipation or urinary retention.
- Certain antifungals, terbinafine and some antivirals: can increase amitriptyline concentrations.
- Enzyme inducers such as carbamazepine: may lower amitriptyline levels and alter response.
- The anticoagulant drug family includes warfarin.: effects on bleeding risk may change and status monitoring may be required.
