DailyMed Drug Label Database
Overview
DailyMed is the National Library of Medicine's official repository of FDA-approved drug labeling information, containing 140,000+ structured product labels (SPLs) for prescription drugs, OTC medications, biologics, and vaccines. The REST API (v2) provides structured JSON/XML access to the full label content including indications, dosage, warnings, contraindications, adverse reactions, and packaging data — with no authentication required.
When to Use
- Retrieving official FDA-approved prescribing information for a drug by name, NDC code, or set ID
- Extracting structured label sections (indications, warnings, dosage, adverse reactions) for pharmacological research
- Looking up all marketed formulations of an active ingredient with packaging and NDC codes
- Cross-referencing drug labels using RxCUI identifiers from RxNorm integration
- Building drug information pipelines that require authoritative FDA label content (not user-reported data)
- Comparing label content across brand name and generic formulations of the same drug
- For adverse event reports from FAERS, use
fda-databaseinstead; DailyMed contains label text, not post-market safety signals - For drug-drug interaction severity data, use
ddinter-database; DailyMed label text is unstructured for interactions

scientific-brainstorming
Structured ideation methods: SCAMPER, Six Thinking Hats, Morphological Analysis, TRIZ, Biomimicry, plus more. Decision framework for picking methods by challenge type (stuck, improving, systematic exploration, contradiction). Use when generating research ideas or exploring interdisciplinary connections.
12snakemake-workflow-engine
Python-based workflow management system for reproducible, scalable pipelines. Define rules with file-based dependencies; Snakemake automatically determines the execution order and parallelism. Supports local, SLURM, LSF, AWS, and Google Cloud execution via profiles; per-rule conda/Singularity environments. Use for bioinformatics NGS pipelines, ML training workflows, and any multi-step file-processing analysis. Use Nextflow instead for Groovy-based dataflow pipelines or when nf-core ecosystem integration is required.
11esm-protein-language-model
Protein language models (ESM3, ESM C) for sequence generation, structure prediction, inverse folding, and protein embeddings. Use when designing novel proteins, extracting sequence representations for downstream ML, or predicting structure from sequence. Local GPU or EvolutionaryScale Forge cloud API. For traditional structure prediction use AlphaFold; for small-molecule cheminformatics use RDKit.
11biopython-sequence-analysis
Biopython sequence analysis: parse FASTA/FASTQ/GenBank/GFF (SeqIO), NCBI Entrez (esearch/efetch/elink), remote/local BLAST, pairwise/MSA alignment (PairwiseAligner, MUSCLE/ClustalW), phylogenetic trees (Phylo). Use for gene family studies, phylogenomics, comparative genomics, NCBI pipelines. For PCR/restriction/cloning use biopython-molecular-biology; for SAM/BAM use pysam.

11archs4-database
Query ARCHS4 REST API for uniformly processed RNA-seq expression, tissue patterns, co-expression across 1M+ human/mouse samples. Retrieve z-scores, co-expressed genes, samples by metadata, HDF5 matrices. For variant population genetics use gnomad-database; for pathway enrichment use gget-genomic-databases (Enrichr).
