How to Monitor Escitalopram and Sertraline Side Effects
How should clinicians target side effect monitoring when prescribing escitalopram or sertraline?
Although many SSRI adverse effects overlap, some symptoms were reported more often with specific agents in this outpatient sample. This guide helps clinicians focus follow-up questions on the side effects that differed significantly for escitalopram and sertraline compared with the other SSRIs studied.
-
Identify the SSRI being monitored
Determine whether the patient is taking escitalopram, sertraline, or fluoxetine before interpreting side effect patterns. In this study, significant between-group differences were found for escitalopram and sertraline, while most other side effects did not differ significantly among the three SSRIs.
-
Monitor escitalopram for specific cognitive, vestibular, and somatic complaints
When the patient is taking escitalopram, ask directly about headache, pruritus, memory impairment, decreased concentration, and dizziness. These adverse effects were reported significantly more often in escitalopram-treated patients in this sample, with P values of .038, .007, .042, .018, and .006, respectively.
-
Monitor sertraline for decreased appetite
When the patient is taking sertraline, specifically assess for decreased appetite. In this study, sertraline was the only SSRI associated with a significant between-group difference for this symptom, with chi-square 6.136 and P = .047.
-
Continue broad surveillance for shared SSRI adverse effects
Do not limit follow-up to only the statistically different symptoms, because many common side effects were reported across the SSRI groups. The study found no significant differences for most other adverse effects, and common complaints overall included flatulence, somnolence, dry mouth, weight gain, light headedness, fatigue, yawning, memory impairment, decreased concentration, and sweating.
-
Ask about unlisted or unexpected symptoms
Include an open-ended adverse-effect question even when using drug-specific prompts. The study detected uncommon additional complaints, including shortness of breath among two patients taking escitalopram and apathy and hair loss among two patients taking sertraline.
Clinical Considerations
- The fluoxetine group was small, with only 8% of the sample taking fluoxetine, which limits interpretation of comparative differences.
- The study compared patient-reported symptoms in a naturalistic setting and does not establish that the SSRI caused every reported symptom.
- No significant between-group differences were found for most measured side effects, so drug-specific monitoring should supplement rather than replace broad side effect review.
Bottom Line
Use targeted follow-up for escitalopram and sertraline by asking specifically about escitalopram-associated headache, pruritus, memory impairment, decreased concentration, and dizziness and sertraline-associated decreased appetite, while still reviewing common SSRI adverse effects broadly.
