Self-Reported Side Effects of Semaglutide and Tirzepatide in Online Communities

arXiv (Cornell University) · 2026-03-12

Social media can reveal patient experiences with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) that extend beyond clinical trial data. We analyzed 410,198 Reddit posts (May 2019-June 2025) mentioning semaglutide or tirzepatide. A total of 67,008 users self-reported using these medications, and 43.5% described at least one side effect. Gastrointestinal symptoms predominated, including nausea (36.9%), fatigue (16.7%), vomiting (16.3%), constipation (15.3%), and diarrhea (12.6%). Notably, reproductive symptoms (e.g., menstrual irregularities) and temperature-related complaints (e.g., chills, hot flashes) emerged as unrecognized potential effects. These findings highlight patient concerns not well captured in current labeling or trials. Large-scale social media analysis can complement traditional pharmacovigilance by detecting emerging safety signals and expanding understanding of the real-world safety profile of GLP-1 RAs.

Use of Naltrexone–Bupropion in Persons With Overweight/Obesity and Symptoms of Depression: A Pooled Analysis

Obesity · 2026-03-31

OBJECTIVE: The present study examined the safety and efficacy of the fixed-dose, extended-release combination of naltrexone and bupropion (NB-ER) in individuals with overweight/obesity and mild to moderate symptoms of depression. METHODS: Data were pooled from four double-blind, placebo-controlled trials. Participants with baseline Inventory of Depressive Symptomatology-Self-Report scores ≥ 14 suggestive of mild or greater depressive symptoms were included (N = 511). Primary outcomes were 56-week percent weight loss and changes in depression, as well as safety data for psychiatric adverse events (PAEs), depressive symptom increases, and suicidal ideation. Multiple imputation was applied, and outcomes were compared in the intention-to-treat population. RESULTS: In participants with symptoms of depression, 56-week weight loss was significantly greater with NB-ER (5.7% ± 0.6%) than with placebo (2.7% ± 0.8%; p = 0.003). Participants experienced clinically meaningful improvements in depression of -7.1 ± 0.4 with NB-ER and -6.7 ± 0.5 with placebo, with no significant differences between the groups. NB-ER and placebo did not differ in safety signals including PAE occurrence (27.5% NB-ER vs. 22.1% placebo), depressive symptom increases (9.5% NB-ER vs. 8.8% placebo), or suicidal ideation (1.8% NB-ER vs. 2.0% placebo). CONCLUSIONS: NB-ER appears to be both safe and effective for weight loss when offered to patients with mild to moderate symptoms of depression.

Anti-obesity medication for weight loss in early nonresponders to behavioral treatment: a randomized controlled trial

Nature Medicine · 2025-03-07 · 6 citations

Current guidelines recommend behavioral treatment (BT) as the first intervention for patients with obesity. However, a substantial minority (35–50%) do not achieve a clinically meaningful loss of ≥5%. Anti-obesity medications (AOMs) are recommended when target weight loss is not achieved; however, their efficacy among BT nonresponders has not been established. This double-blind, randomized controlled proof-of-principle study evaluated whether augmenting BT with AOM improved 24-week weight loss compared to BT with placebo in early nonresponders to BT. A total of 147 adults with a body mass index ≥31 kg m−2 (≥28 kg m−2 with obesity-related comorbidity) completed an initial 4-week BT run-in. The 76 early nonresponders who lost <2.0% of initial weight were then randomized to 24 weeks of either BT plus placebo (BT + P, n = 38) or BT plus AOM (phentermine = 15.0 mg d−1, n = 38). Early responders received ongoing BT and were not part of the randomized trial. The primary outcome was met; early nonresponders assigned to BT + AOM had a greater mean (±s.e.) reduction in weight of 5.9 ± 0.7% from randomization to week 24, as compared to 2.8 ± 0.7% for those assigned to BT + P (mean difference = 3.1 ± 1.0, 95% confidence interval = 1.1–5.1%, Cohen’s d = 0.73, P = 0.003). Stepping up early BT nonresponders to BT + AOM improves their 24-week weight loss. ClinicalTrials.gov registration: NCT03779048 . A randomized clinical trial showing the superiority of behavioral treatment plus phentermine to behavioral treatment plus placebo for weight loss in those that previously had not responded to behavioral treatment.

Are fewer cases of diabetes mellitus diagnosed in the months after SARS-CoV-2 infection? A population-level view in the EHR-based RECOVER program

UNC Libraries · 2023-06-10

Long-term sequelae of severe acute respiratory coronavirus-2 (SARS-CoV-2) infection may include increased incidence of diabetes. Here we describe the temporal relationship between new type 2 diabetes and SARS-CoV-2 infection in a nationwide database. We found that while the proportion of newly diagnosed type 2 diabetes increased during the acute period of SARS-CoV-2 infection, the mean proportion of new diabetes cases in the 6 months post-infection was about 83% lower than the 6 months preinfection. These results underscore the need for further investigation to understand the timing of new diabetes after COVID-19, etiology, screening, and treatment strategies.
