A nurse is providing teaching to a client who has neuropathic pain and a new prescription for amitriptyline once per day. Which of the following information should the nurse include in the teaching?

A. Increase fluids while taking the medication: Amitriptyline is a tricyclic antidepressant that can cause anticholinergic side effects such as dry mouth and constipation. Increasing fluid intake helps to mitigate these effects and prevent dehydration and constipation. B. Expect an elevation in blood pressure with initial doses of the medication: Amitriptyline can cause orthostatic hypotension rather than elevated blood pressure. Clients should be informed about the risk of dizziness or fainting. C. Stop the medication immediately if urine becomes orange in color: Orange urine is not a common side effect of amitriptyline. Clients should not stop the medication without consulting their provider. D. Take the medication in the morning: Amitriptyline has sedative effects and is typically taken at night to help manage sleep disturbances and reduce daytime drowsiness.
