NHS Warns: Toilet Bleeding May Signal Danger
19 May
Summary
- Internal bleeding is a serious side effect of apixaban.
- Blood in urine or stool requires immediate medical attention.
- Always carry your anticoagulant alert card with you.

Individuals prescribed apixaban, a widely used anticoagulant, are being alerted by the NHS to a potentially serious side effect. The medication, designed to prevent dangerous blood clots, can cause bleeding more than usual. A key concern highlighted is the appearance of blood in urine or stool, which may signal internal bleeding and necessitates an immediate call to NHS 111.
More severe bleeding can occur, and patients experiencing this symptom are urged to seek medical advice promptly. Other rare but serious side effects include severe allergic reactions and dangerously low blood pressure. The NHS emphasizes that all patients on apixaban should carry an anticoagulant alert card, presenting it before any medical or dental procedures.
