Ticagrelor Side Effects

Most people tolerate ticagrelor well, but side effects are always a possibility. If adverse reactions do occur, they often involve symptoms like headache, dizziness, and shortness of breath. If you develop any potentially serious problems, such as coughing up blood or any other signs of bleeding, contact your healthcare provider right away.

An Introduction to Ticagrelor Side Effects

Just like any medicine, ticagrelor (Brilinta™) can cause side effects. Because it affects the blood's ability to form clots, potentially serious reactions are possible. Many of these are related to the risk of bleeding.
(This article covers many, but not all, of the possible side effects with ticagrelor. Your healthcare provider can discuss a more complete list with you.)

Serious Side Effects of Ticagrelor

As mentioned, some ticagrelor side effects are potentially serious and should be reported immediately to your healthcare provider. These include but are not limited to:
  • Shortness of breath (although shortness of breath is a common side effect of ticagrelor and is not usually dangerous, your healthcare provider should still make sure this symptom is not caused by other, more serious problems)

    • Blood in the urine

    • Bleeding gums
    • Bleeding from cuts that takes a long time to stop
