Ticagrelor: What It Is, How It Works, and What You Need to Know

When you’re at risk for a heart attack or stroke, your doctor might prescribe ticagrelor, a direct-acting antiplatelet medication that stops blood clots from forming by blocking platelet activity. Also known by its brand name Brilinta, it’s one of the most commonly used drugs after a heart event or for people with severe coronary artery disease. Unlike older drugs like clopidogrel, ticagrelor works faster, doesn’t need to be converted by the liver to become active, and has a more predictable effect—making it a go-to for many cardiologists.

Ticagrelor is part of a larger group of drugs called P2Y12 inhibitors, which target a specific receptor on platelets to keep them from sticking together. It’s often paired with low-dose aspirin to give double protection against clots. People who’ve had a heart attack, unstable angina, or a stent placed in their heart arteries are the most common users. Studies show it reduces the risk of another heart attack or death from heart disease better than clopidogrel in many cases—but it also comes with a higher chance of bleeding, so it’s not for everyone.

Some people notice shortness of breath when they start taking ticagrelor. It’s not an allergy or lung problem—it’s a known side effect tied to how the drug affects certain chemicals in the body. Most get used to it within a few weeks. Other common issues include bruising easily, nosebleeds, or upset stomach. You’ll need to avoid certain painkillers like ibuprofen, which can interfere with its action. And you should never stop taking it suddenly unless your doctor tells you to—stopping too soon can trigger a clot.

There’s no one-size-fits-all when it comes to blood thinners. While some people do better on clopidogrel or prasugrel, others respond best to ticagrelor. Factors like age, kidney function, other medications, and even genetics can influence how well it works for you. If you’ve been on it for a while, you’ve probably noticed how it fits—or doesn’t fit—into your daily life. Maybe you’ve had to adjust your diet, avoid certain supplements, or schedule regular check-ups to monitor your blood.
