Welcome to nSIDES

nSIDES is the home for the drug side effect and drug interaction resources made available from the Tatonetti Lab at Columbia University. Below you will find descriptions of each of the resources with links to download the data and access the code. Please reach out if you have any questions and share how you're using these resources!

Drug side effects extracted from structured product labels.

OnSIDES (ON label SIDE effectS resource) is the newest member of the NSIDES family. The initial release (v01) of the OnSIDES database of adverse reactions and boxed warnings extracted from the FDA structured product labels. All labels available to download from DailyMed ( as of April 2022 were processed in this analysis. In total 2.7 million adverse reactions were extracted from 42,000 labels for just under 2,000 drug ingredients or combination of ingredients.

We created OnSIDES using the ClinicalBERT language model and 200 manually curated labels available from Denmer-Fushman et al.. The model achieves an F1 score of 0.86, AUROC of 0.88, and AUPR of 0.91 at extracting effects from the ADVERSE REACTIONS section of the label and an F1 score of 0.66, AUROC of 0.71, and AUPR of 0.60 at extracting effects from the BOXED WARNINGS section.


The data are available as a set of SQL tables or as CSV flat files.

A resource of pediatric drug safety signals.

Adverse drug events are responsible for up to 10% of pedaitric hospitalizations and drug side effects are primaryYeah safety concerns in pediatrics. Unfortunately, due to the structural and ethical challenges of including children in clinical trials, there is little information available. We invented a method that leverages post-marketing adverse drug event reports to identify drug safety signals that vary across the developmental phases of childhood. We systematically applied this method across all adverse events and all childhood developmental phase to produce a database of pediatric drug safety signals, called KidSIDES. You can access the manuscript, source code, data files, and web portal for KidSIDES below.



The PDSPortal is a RShiny application we created to enable browsing of the pediatric drug safety signals. You can access it at

Off label drug side effect and drug-drug interaction safety signals.

Drug side effects and drug-drug interactions were mined from publicly available data. OffSIDES (OFF label drug SIDE effectS) is a database of drug side-effects that were found, but are not listed on the official FDA label. TwoSIDES is the only comprehensive database drug-drug-effect relationships. Over 3,300 drugs and 63,000 combinations connected to millions of potential adverse reactions.

Note that these resources are quite a bit out of date. We will be updating them for 2022 and then including them our routine quarterly updates going forward. As the repositories and project pages are built out for these projects, they will be posted here.


The data are available as flat files in this directory.


Side effect signals for combinations of drugs (3+).

ManySIDES (currently called nsides v0.1 but in the process of transitioning to its new name) is our resource for drug combination side effects and is currently under active development. You can read more about v0.1 in the release notes and the code repository.
