NAPLEX Practice Exam 2025 – Comprehensive Test Preparation

Question: 1 / 1820

What special precaution is associated with the use of tricyclic antidepressants (TCAs)?

QT prolongation

TCAs are known to have a potential side effect of QT prolongation. QT prolongation is a condition that affects the electrical rhythm of the heart, causing an abnormal heartbeat. It is important for individuals taking TCAs to regularly monitor their heart rhythm and report any changes to their doctor. The other options are incorrect because they are not specific to the use of TCAs and may be potential side effects of other medications. Rapid weight loss, increased urination, and decreased appetite may also be symptoms of underlying medical conditions that should be discussed with a doctor.
