Final answer:
The psychiatrist should proceed cautiously when adding nortriptyline as an adjunct to fluoxetine due to the risk of serotonin syndrome. Close monitoring of the patient is essential to detect any symptoms and adjustments may be necessary to minimize the risk.
Step-by-step explanation:
To add nortriptyline as an adjunct to fluoxetine, the psychiatrist should follow a cautious approach due to the potential for drug interactions. The combination of nortriptyline, a tricyclic antidepressant, and fluoxetine, a selective serotonin reuptake inhibitor (SSRI), can increase the risk of serotonin syndrome. Serotonin syndrome is a potentially life-threatening condition that can occur when there is an excessive amount of serotonin in the brain.
The psychiatrist should carefully monitor the patient for symptoms of serotonin syndrome, such as agitation, confusion, rapid heart rate, and high blood pressure. If any symptoms are observed, prompt medical attention should be sought. The dosage of both medications may need to be adjusted to minimize the risk of serotonin syndrome.
