Tools (3)

`check_interactions`

Check drug-drug interactions for Norwegian medications via interaksjoner.no. This tool checks interactions between two or more medications using data from FEST (Forskrivnings- og EkspedisjonsSTøtte), the official Norwegian prescription and dispensing support database maintained by DMP (Direktoratet for medisinske produkter). Severity levels: - Level 4: "Bør ikke kombineres" — should not be combined, risk of serious adverse effects - Level 2: "Ta forholdsregler" — take precautions, monitor patient - Level 1: "Akademisk interesse" — academic interest, can generally be combined Returns: Recognized drugs with ATC codes, list of interactions with severity levels, descriptions, and clinical notes. If no interactions are found, returns no_interactions_found=true.

Parameter	Type	Required	Description
`drugs`	list[string]	required	List of drug names, substance names, or ATC codes to check for interactions. Accepts Norwegian trade names (e.g. 'Paracet', 'Marevan'), international substance names (e.g. 'paracetamol', 'warfarin'),
