From the Guidelines
Ticagrelor should not be immediately discontinued for minor rectal bleeding without consulting a healthcare provider. For patients on ticagrelor for acute coronary syndrome or coronary stenting, premature discontinuation increases the risk of serious cardiovascular events including stent thrombosis 1. When minor rectal bleeding occurs, the patient should seek medical evaluation to determine the bleeding source while continuing the medication. The healthcare provider may recommend continuing ticagrelor with close monitoring if the bleeding is minor and self-limited. However, if bleeding is persistent or worsening, temporary interruption might be necessary while addressing the underlying cause. During any interruption, the shortest possible duration should be targeted to minimize thrombotic risk. Some key points to consider include:
- The risk of bleeding associated with ticagrelor is higher than with clopidogrel 1
- The decision to stop ticagrelor depends on the individual's thrombotic risk, the severity of bleeding, and the time elapsed since the initial indication for antiplatelet therapy 1
- Patients should be educated to report any bleeding immediately and understand that self-discontinuation without medical consultation could lead to serious consequences 1
- In general, for patients with a history of acute coronary syndrome, ticagrelor should be continued for at least 12 months, unless the risk of bleeding outweighs the benefit 1. It is essential to weigh the risks and benefits of continuing or stopping ticagrelor in each individual case, considering the latest evidence and guidelines 1.
From the Research
Gastrointestinal Bleeding Risk with Ticagrelor
- The risk of gastrointestinal bleeding with ticagrelor is a concern, as it is a potent antiplatelet medication 2.
- A study found that third-generation P2Y12 inhibitors, including ticagrelor, were associated with a higher risk of gastrointestinal bleeding compared to clopidogrel (RR 1.28,95% CI 1.13-1.46) 2.
- Another study found that clopidogrel is safer than ticagrelor with regard to GI-related risks, including fewer overall GI/anal bleeding events and spontaneous GI hemorrhagic episodes 3.
Management of Gastrointestinal Bleeding
- The management of gastrointestinal bleeding depends on the underlying cause and severity of the bleed 4.
- For patients taking ticagrelor, the decision to stop the medication due to a small amount of rectal bleeding should be made on a case-by-case basis, considering the individual's risk factors and medical history 5, 6.
- Proton pump inhibitors (PPIs) may be prescribed to reduce the risk of gastrointestinal bleeding in patients taking antiplatelet medications, including ticagrelor 6.
Considerations for Ticagrelor Use
- Ticagrelor is a potent antiplatelet medication that requires careful consideration of the benefits and risks, including the risk of gastrointestinal bleeding 5, 2.
- Patients taking ticagrelor should be monitored closely for signs of gastrointestinal bleeding, and the medication should be stopped if bleeding occurs 3.
- The use of PPIs and other gastroprotective agents may be considered to reduce the risk of gastrointestinal bleeding in patients taking ticagrelor 6.
