Which of the following is a contraindication for Tricyclic Antidepressants (TCAs)?

Tricyclic Antidepressants (TCAs) have a range of side effects and contraindications that must be considered when prescribing them. Low blood pressure is indeed a contraindication for TCAs because these medications can potentially exacerbate this condition. TCAs can lead to orthostatic hypotension, where blood pressure drops significantly when a person stands up from sitting or lying down, resulting in dizziness or fainting.

In contrast, hypertension is not a contraindication in a straightforward sense; in fact, certain TCAs are sometimes used in patients with hypertension under careful monitoring. Osteoporosis and diabetes are also conditions that require caution when prescribing medications, but they do not serve as direct contraindications for the use of TCAs inasmuch as low blood pressure does. Monitoring and management strategies exist for patients with osteoporosis and diabetes that would allow for the safe use of these antidepressants, provided overall patient health is assessed appropriately.
