Checking that the SKILL.md file is still in the repository.
Query the nSIDES drug side effect databases (OnSIDES, OffSIDES, KidSIDES). Use whenever the user asks about drug adverse reactions, side effects, off-label safety signals, or pediatric drug safety for a given drug name.

nSIDES Query Skill
Search drug adverse reactions across three complementary nSIDES sources by drug name.
| Source | Content | Method | Scale | |
|---|---|---|---|---|
| OnSIDES v3.1.0 | Label-extracted ADEs (US/EU/UK/JP) | PubMedBERT NLP on product labels | 1,955 ingredients, 5.5M drug-ADE pairs | |
| OffSIDES | Off-label side effects | Propensity-score matching on FAERS | 3,300+ drugs | |
| KidSIDES | Pediatric safety signals by developmental phase | Disproportionality analysis on FAERS | Age-stratified ADE signals |
Entity Detection
| Input | Routing | |
|---|---|---|
| any free text | substring match on drug / ingredient name across all three sources |
No ID-based routing — all queries are natural-language drug names.
API
| Function | Input | Returns | |
|---|---|---|---|
search(entity, limit) | drug name string | dict with keys: entity, onsides, offsides, kidsides | |
search_batch(entities, limit) | list of drug names | list[dict] | |
search_onsides(drug_name, limit) | drug name | list[dict] — ingredient, effect, meddra_id, source, label_count | |
search_offsides(drug_name, limit) | drug name | list[dict] — drug, condition, PRR, A/B/C/D | |
search_kidsides(drug_name, limit) | drug name | list[dict] — drug, event, nichd_phase, gam_score, ror | |
summarize(result) | single search() output | compact text | |
to_json(result) | single search() output | JSON string |
Output Fields
OnSIDES row
ingredient— RxNorm ingredient nameeffect— MedDRA adverse effect termmeddra_id— MedDRA concept IDsource— label origin country (US / EU / UK / JP)label_count— number of labels reporting this ADE
OffSIDES row
drug— RxNorm drug namecondition— MedDRA side effect namePRR— proportional reporting ratio (>1 = signal)A/B/C/D— 2×2 contingency countsmean_reporting_frequency— proportion of drug reports with this effect
KidSIDES row
drug— drug concept nameevent— adverse event namenichd_phase— NICHD developmental phase (e.g. "Neonatal", "Infancy", "Adolescence")gam_score— GAM model scoreror/ror_lower/ror_upper— reporting odds ratio with 95% CI
Usage
See if __name__ == "__main__" block in 15_nSIDES.py for runnable examples: single-drug query, batch query, text summary, and JSON output.
