SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires tooluniverse.

What problem does it solve? Assessing drug-drug interactions manually requires searching DrugBank, FDA labels, PubMed, and FAERS separately, then synthesizing mechanisms, severity, and management guidance into a coherent clinical recommendation. ## Core Features & Use Cases - Bidirectional DDI Analysis: Queries DrugBank, RxNorm, DailyMed, PubMed, and FAERS to detect interactions in both directions (A→B and B→A) with CYP450, transporter, and pharmacodynamic mechanism identification. - Risk Scoring & Evidence Grading: Produces a 0-100 risk score with Major/Moderate/Minor severity classification and star-rated evidence grades (FDA label, clinical study, theoretical). - Polypharmacy & Alternatives: Supports 3+ drug regimens with pairwise DDI matrices, plus safer alternative drug recommendations and monitoring schedules. - Use Case: A clinician asks whether simvastatin can be taken with ketoconazole; the Skill generates a markdown report identifying the CYP3A4 contraindication and recommending pravastatin or rosuvastatin instead. ## Quick Start Analyze the drug interaction risk between warfarin and amoxicillin and generate a clinical management report.

Frequently Asked Questions about tooluniverse-drug-drug-interaction

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check drug interactions between two medications?▼

Provide the two drug names and the Skill queries DrugBank for documented interactions in both directions, then checks FDA labels, PubMed literature, and FAERS adverse event reports. It outputs a markdown report with a risk score, severity classification, and management recommendations.

What data sources are used for drug interaction analysis?▼

The pipeline uses ToolUniverse tools covering RxNorm for drug identification, DrugBank for interaction mechanisms and pharmacology, DailyMed for FDA label warnings, PubMed for clinical literature, and FAERS for post-market adverse event surveillance.

Can this analyze polypharmacy with more than two drugs?▼

Yes, the Skill supports polypharmacy analysis of three or more medications by computing all pairwise interactions and presenting them in a DDI matrix with an overall polypharmacy risk score and prioritized monitoring schedule.

How is the DDI risk score calculated?▼

The score ranges from 0-100, adding points for identified mechanisms, FDA label warnings, literature evidence, and FAERS report volume. Scores of 70+ are classified Major, 40-69 Moderate, and below 40 Minor.

Why does the report show no interaction for a known drug pair?▼

The pipeline depends on DrugBank query results, and name-matching or API failures can return empty interactions. The report explicitly documents failed tool calls and empty results rather than fabricating findings, so verify drug name spelling and retry.

Does the Skill recommend alternative drugs to avoid interactions?▼

Yes, for major interactions it suggests safer alternatives in the same therapeutic class with different metabolic pathways, such as recommending pravastatin or rosuvastatin instead of simvastatin when combined with strong CYP3A4 inhibitors.
