Antidepressant side effects and their impact on treatment outcome in people with major depressive disorder: an iSPOT-D report
Open accessAbstract
Side effects to antidepressant medications are common and can impact the prognosis of successful treatment outcome in people with major depressive disorder (MDD). However, few studies have investigated the severity of side effects over the course of treatment and their association with treatment outcome. Here we assessed the severity of side effects and the impact of treatment type and anxiety symptoms over the course of treatment, as well as whether side effects were associated with treatment outcome. Participants were N = 1008 adults with a current diagnosis of single-episode or recurrent, nonpsychotic MDD. Participants were randomised to receive escitalopram, sertraline, or venlafaxine-extended release with equal probability and reassessed at 8 weeks regarding Hamilton Rating Scale Depression (HRSD 17 ) and Quick Inventory of Depressive Symptomatology (QIDS-SR 16 ) remission and response. Severity of side effects were assessed using the Frequency, Intensity, and Burden of Side Effects Rating (FIBSER) scale and assessed at day 4 and weeks 2, 4, 6, and 8. Frequency, intensity, and burden of side effects were greatest at week 2, then only frequency and intensity of side effects gradually decreased up to week 6. Treatment type and anxiety symptoms did not impact the severity of side effects. A greater burden—but not frequency or intensity—of side effects was associated with poorer treatment outcome and as early as 4 days post-treatment. Together, this work provides an informative mapping of the progression of side effects throughout the treatment course and their association with treatment outcome. Importantly, the burden of side effects that are present as early as 4 days post-treatment predicts poorer treatment outcome and should be monitored closely. iSPOT-D: Registry name: ClinicalTrials.gov.

TL;DR
In N = 1008 adults with major depressive disorder randomized to escitalopram, sertraline, or venlafaxine-XR, side-effect frequency, intensity, and burden peaked at week 2; frequency and intensity then declined up to week 6, while burden did not decline after week 4. Greater side-effect burden predicted poorer treatment outcome, including as early as day 4, whereas treatment type and anxiety symptoms did not affect side-effect severity.
Key findings
- Side effects were greatest at week 2. Frequency and intensity gradually decreased up to week 6, but burden did not decrease after week 4 and endured throughout treatment; mean FIBSER burden was 0.56 (SD 1.11) at day 4, 0.88 (SD 1.25) at week 2, 0.90 (SD 1.20) at week 4, 0.81 (SD 1.18) at week 6, and 0.85 (SD 1.20) at week 8.
- Treatment type, DASS42 anxiety, HRSD17 anxiety/somatization, and presence of anxious depression did not improve model fit for side-effect severity (e.g., treatment type p = 0.162 for frequency, p = 0.091 for intensity, p = 0.149 for burden; anxiety predictors all p > 0.05). There were also no differences in maximum frequency, intensity, or burden between anxious and non-anxious depression.
- Greater burden of side effects was associated with poorer QIDS-SR16 remission and response at every timepoint except week 4 QIDS-SR16 response; at day 4, QIDS-SR16 remission OR = 0.69 (95% CI 0.51–0.92, p = 0.016) and response OR = 0.70 (95% CI 0.53–0.91, p = 0.010). For HRSD17, greater burden at week 2 was associated with poorer remission (OR = 0.76, 95% CI 0.60–0.95, p = 0.015), and greater intensity at week 6 was associated with poorer remission (OR = 0.68, 95% CI 0.50–0.93, p = 0.015).
- Adverse events occurred in 473/1008 participants (46.9%); 1016 adverse events were reported, of which 804 (79.1%) were related to antidepressant treatment. Adverse events were not associated with HRSD17 or QIDS-SR16 remission and response (all p > 0.05).
Methods
- Phase-IV, multi-site, international, randomized, open-label trial; N = 1008 adults aged 18–65 with current single-episode or recurrent, nonpsychotic MDD diagnosed by MINI-Plus per DSM-IV, requiring HRSD17 > 16 at entry. Participants were randomized with equal probability to escitalopram, sertraline, or venlafaxine-extended release; data were collected between December 1, 2008 and September 30, 2013.
- Side-effect severity was measured with the self-reported FIBSER at day 4 and weeks 2, 4, 6, and 8. Depression severity was assessed with HRSD17 and QIDS-SR16; remission was HRSD17 ≤ 7 or QIDS-SR16 ≤ 5, and response was ≥50% decrease from baseline.
- Hierarchical linear mixed-effect models tested timepoint, treatment type, anxiety measures, and anxious depression against side-effect scores, with subject as a random effect and covariates age, sex, baseline QIDS-SR16, dosage at study outcome, and age of MDD onset; model comparison used AIC/BIC. Pearson correlations and logistic regression models, adjusted for the same covariates, tested associations between side effects and treatment outcome.
Limitations
- Stated in the paper: findings are limited to the antidepressants used in the study; specific side effects were not assessed and side effects could not be matched with their corresponding severity; allowed non-psychotropic medications may have been misinterpreted as study-treatment side effects; and DSM-IV criteria were used, so the DSM-5 anxious distress specifier was not assessed.
- Evident from the text: the trial was open-label with no placebo arm and participants knew which medication they were taking, so expectancy effects on side-effect reporting cannot be ruled out. Also, both FIBSER and QIDS-SR16 are self-reported, which the paper notes may help explain why burden associations were found for QIDS-SR16 but not clinician-rated HRSD17.

In the paper
“Given that we found no differences in either the maximum reported side effects or frequency, intensity, and burden of side effects across timepoints between people with anxious and non-anxious depression, our difference in findings may be attributable to either a difference in the clinical severity of samples or lack of covariate controls.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
