Data has accumulated to suggest that intraoperative floppy iris syndrome (IFIS) is a possible class effect of α-1 adrenoreceptor antagonists, which are used to treat benign prostatic hyperplasia. IFIS is a newly identified syndrome that can lead to surgical complications during cataract surgery.
An association between IFIS and the α-1 adrenoreceptor antagonist tamsulosin has previously been identified and advice communicated to healthcare professionals. A warning is now being added to the product information for all α-1 adrenoreceptor antagonists, advising patients to inform their cataract surgeon about past or current use of these medicines before surgery to ensure that appropriate measures are in place should IFIS occur.
