“Pulmonary embolism?”

No. Not at all. Aspirin nor NSAIDs which includes ibuprofen are not treatment for thromboembolism to the lungs. Aspirin in certain circumstances can be used as a prophylaxis for thromboembolic disease such as DVT after certain orthopedic surgery, To dissolve clots by medications requires thrombolytic medication which is very dangerous for bleeding to death and is done in a critical care hospitalized setting. Most common treatment would be an anticoagulant, such as apixaban, but this doesn't dissolve clots. Your own immune system slowly "dissolve" the clots over time.

Ibuprofen would have no effect whatsoever. Aspirin would prevent further platelet aggregation causing more of a clot. Other than that, it would have no therapeutic effect. Do you need much stronger medication a pulmonologist, a VQ scan, even an MRI or a chest CT or angiogram or a combination of them all in order to delineate the pulmonary embolism size, and a multitude of others? It’s best suited to speak with your pulmonary doctor about the most appropriate course of action. Indeed, blood thinners such as heparin, warfarin, etc.
Thank you for asking me. I pray for your health.

Be well,
