Use cautiously with geriatric patients, patients with hepatic impairment, and those who take antidepressants and other CNS depressants.\n\nIn the elderly, the frequency and severity of adverse events associated with the use of cyclobenzaprine, with or without concomitant medications, are increased. In elderly patients, cyclobenzaprine should be initiated with a 5 mg dose and titrated slowly upward.\n\n<strong>Adverse\/Side Effects <\/strong>\n\nAdverse effects include dizziness, drowsiness, dry mouth, urinary retention, serotonin syndrome with antidepressant use, or increased sedation with other CNS depressants.\n\n<strong>Patient Teaching &amp; Education<\/strong>\n\nThe medication should be taken as directed.\u00a0 It may cause dizziness or drowsiness.\u00a0 Patients should be advised to change positions slowly because of the potential orthostatic changes that may occur.\u00a0 Additionally, patients should avoid concurrent use with alcohol or other CNS depressants.\u00a0 Patients should be aware that constipation may occur as a side effect of medication therapy and increased fluid intake may assist in preventing complications.<sup>[footnote]uCentral from Unbound Medicine. <a href=\"https:\/\/www.unboundmedicine.com\/ucentral\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.unboundmedicine.com\/ucentral<\/a>[\/footnote]<\/sup>\n\n<strong>Serotonin Syndrome<\/strong>\n\nThe development of a potentially life-threatening serotonin syndrome has been reported with cyclobenzaprine hydrochloride when used in combination with other drugs, such as selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), tramadol, bupropion, meperidine, verapamil, or MAO inhibitors (MAOIs). The concomitant use of cyclobenzaprine hydrochloride with MAO inhibitors is contraindicated.\n\nSerotonin syndrome symptoms may include mental status changes (e.g., confusion, agitation, hallucinations), autonomic instability (e.g., diaphoresis, tachycardia, labile blood pressure, hyperthermia), neuromuscular abnormalities (e.g., tremor, ataxia, hyperreflexia, clonus, muscle rigidity), and\/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Treatment with cyclobenzaprine hydrochloride and any concomitant serotonergic agents should be discontinued immediately if the above reactions occur, and supportive symptomatic treatment should be initiated. If concomitant treatment with cyclobenzaprine hydrochloride and other serotonergic drugs is clinically warranted, careful observation is advised, particularly during treatment initiation or dose increases.\n\n<strong>General<\/strong>\n\nBecause of its atropine-like action, cyclobenzaprine hydrochloride should be used with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in those taking anticholinergic medication.\n\n<strong>Impaired Hepatic Function<\/strong>\n\nThe plasma concentration of cyclobenzaprine is increased in patients with hepatic impairment.\n\nCyclobenzaprine, especially when used with alcohol or other CNS depressants, may impair mental and\/or physical abilities required for performance of hazardous tasks, such as operating machinery or driving a motor vehicle.\n\nNow let\u2019s take a closer look at the medication grid on cyclobenzaprine in Table 10.8b.<sup>[footnote]Vallerand, A., Sanoski, C.
