Clinical Disclaimer: Drug Interactions

Class-Level Flags: Interaction flags in Column R represent broad drug classes and must be verified by a clinical pharmacist against the BNF.

1. Additive Bleed Risk: Antiplatelets (Aspirin, Clopidogrel), NSAIDs (Ibuprofen, Naproxen), SSRIs/SNRIs & Steroids impair haemostasis → triggers Bleeding Risk SMS template in Clinical Notes.
2. Increased DOAC Plasma Levels: CYP3A4/P-gp inhibitors (Amiodarone, Diltiazem/Adizem, Verapamil, Clarithromycin, Azoles) slow clearance → increases bleeding risk; review dose/monitoring & triggers Bleeding Risk SMS template.
3. Enzyme Inducers (Thrombosis Risk): Carbamazepine, Phenytoin, Rifampicin & St John's Wort accelerate clearance → high risk of DOAC failure / clot. Bleeding SMS is suppressed; urgent prescriber review required.

Important context for clinical governance:
• Child-Pugh Score: Flags elevated ALT/Bili but does not calculate Child-Pugh score for severe hepatic disease.
• Medication Adherence: Checks if DOAC is on repeat, but does not analyse issue dates to confirm compliance.
• OTC / Herbals: Only flags drugs in Column R. Cannot detect unprescribed OTC NSAIDs or St John's Wort.
• Risk Scores: Does not calculate or monitor HAS-BLED, ORBIT, or CHA2DS2-VASc scores.
• Recent Acute Events: Does not screen for recent GI bleeds, planned surgeries, or acute AKI between bloods.
• Contraindications: Does not check for pregnancy or breastfeeding status.
