⚠ Key cautions
Cautions: CONTRAINDICATED in pregnancy — feverfew has traditional uterine-stimulant/emmenagogue use; may trigger mild transient oral or GI discomfort; abrupt discontinuation after prolonged use has been associated with rebound headache ('post-feverfew syndrome') — taper if discontinuing after long-term use. Prescription interactions: mild antiplatelet effect — caution with anticoagulants/antiplatelets (bleeding risk); NSAIDs may theoretically reduce feverfew's antimigraine efficacy; contraindicated in Asteraceae/Compositae family allergy (ragweed, daisies, chrysanthemums, marigolds). Priority: High — clear pregnancy contraindication plus established bleeding-risk interaction.
