PE treatment options: What to expect and common approaches

If you or someone you care about has a pulmonary embolism (PE), knowing the usual treatment options can make decisions less scary. A PE happens when a blood clot travels to the lungs and blocks blood flow. Symptoms often include sudden shortness of breath, chest pain that gets worse when you breathe, fast heartbeat, lightheadedness, or coughing up blood. If any of these happen, get urgent medical help.

Most PE care focuses on stopping the clot from growing, preventing new clots, and protecting the lungs and heart. Doctors usually start with anticoagulant medicines—these thin the blood so clots can’t get bigger. Common choices are low molecular weight heparin (LMWH) in the hospital, then an oral anticoagulant like apixaban, rivaroxaban, dabigatran, or warfarin. Many people stay on anticoagulants for about three months after a PE that had a clear trigger, like surgery or a long trip. If the PE had no clear cause, or if you have ongoing risk factors, treatment may last longer or be lifelong.

When clot-busting or procedures are needed

For large or life-threatening PEs that affect blood pressure or oxygen levels, doctors may use thrombolysis—medicines that dissolve clots quickly. Thrombolytics carry a higher bleeding risk, so teams weigh benefits and risks carefully. In certain cases, catheter-directed thrombolysis or mechanical clot removal through a minimally invasive procedure can be used to target the clot and reduce bleeding risk. Rarely, open surgical embolectomy is done when other options aren’t possible.

Other treatments and follow-up

Sometimes teams place an inferior vena cava (IVC) filter to catch clots coming from the legs when anticoagulation is not safe. Oxygen, fluids, and pain relief support recovery. After the acute phase, follow-up includes checking how well the anticoagulant is working, watching for bleeding, and testing for underlying causes like clotting disorders or cancer when appropriate.

Prevention matters. If you’re headed for surgery or a long flight, simple steps like moving often, using compression stockings, and following doctor advice on blood thinners can cut risk. Lifestyle steps—staying active, managing weight, and quitting smoking—also help long term.

Decisions about which medicine, how long to treat, or whether to use procedures are personal and depend on your health, bleeding risk, and the cause of the PE. Talk with your healthcare team, ask about risks and benefits, and get clear instructions about symptoms that need immediate care.

Keep a medication card listing your anticoagulant and dose, and tell every doctor or dentist you see about it. Watch for warning signs like unusual bruising, heavy bleeding, severe headache, or black stools — call right away if they appear. Pregnant people and those with cancer need a tailored plan; low molecular weight heparin is often preferred in pregnancy. If cost or access is a problem, ask about patient assistance programs or generic options. Always carry ID noting your anticoagulant and emergency contact details.
