Concomitant SSRIs and oral anticoagulants up major bleed risk: study

The likelihood of major bleeding peaks in the first 30 days of concomitant use, researchers say.

Concomitant use of SSRIs and oral anticoagulants increases the risk of major bleeding by a third in older adults with AF compared with use of oral anticoagulants alone, Canadian doctors report.

Their results, published in JAMA Network Open, suggest the likelihood of major bleeds peaks in the first 30 days of concomitant use and persists for up to six months.
