News item update
Update provided on 20 September.
We are seeing an increase of suspected adverse event reports following use of intravenous co-amoxiclav (amoxicillin and clavulanic acid) products.
These reports often include anaphylaxis/hypersensitivity signs with a rapid onset, usually within minutes of administration of the product. The most frequently reported signs are urticaria, allergic oedema (often facial/periocular), erythema and pruritus. This can also be accompanied by hypotension and tachycardia.
We are working with the Marketing Authorisation Holders to investigate this finding and are closely monitoring reports.
