Hip replacement surgery, whether involving a valve replacement or not, carries a significant risk of blood clots. This is because the surgery is invasive and immobilises the patient for a period of time, increasing the chance of blood pooling. Aspirin, a blood thinner, is often prescribed to mitigate this risk. However, the duration of aspirin use after hip replacement surgery is a matter that needs careful consideration and should always be discussed with your surgeon and medical team. There's no one-size-fits-all answer.

What is the Purpose of Aspirin After Hip Replacement?
The primary reason for prescribing aspirin (or other blood thinners like warfarin or newer anticoagulants) after hip replacement is thromboprophylaxis. This means preventing the formation of blood clots (thrombi) in the legs and pelvis, which can travel to the lungs (pulmonary embolism) or brain (stroke), causing serious complications or even death. The risk of these events is significantly higher in the weeks following major surgery.
How Long Will My Doctor Recommend Taking Aspirin?
The length of time you'll need to take aspirin (or other anticoagulants) varies greatly depending on several factors:
- Your individual risk factors: Age, pre-existing conditions (such as a history of blood clots), smoking, obesity, and other health issues can all influence the risk assessment.
- Type of hip replacement: The surgical technique and type of prosthesis used might influence the risk of complications.
- Your post-operative recovery: Your mobility and overall progress after surgery play a role in determining the duration of anticoagulant therapy. Patients who are more mobile tend to have a lower risk of clot formation.
- The specific protocol of your surgeon: Each surgeon may have different preferences based on their experience and assessment of individual patient needs.
What Happens if I Stop Taking Aspirin Too Soon?
Stopping aspirin prematurely increases the risk of blood clot formation. This could lead to serious complications like deep vein thrombosis (DVT), pulmonary embolism (PE), or stroke.
What Happens if I Take Aspirin for Too Long?
While the risk of bleeding increases with prolonged aspirin use, this is balanced against the risk of blood clots. Your doctor will monitor you and adjust your medication as needed to find the optimal balance of risk and benefit. Prolonged use may also increase the risk of gastrointestinal issues.
What are the Alternatives to Aspirin?
Besides aspirin, other blood thinners such as warfarin, apixaban, rivaroxaban, and dabigatran are often prescribed for thromboprophylaxis after hip replacement surgery. The choice depends on your individual circumstances and your doctor's assessment.
Can I Take Aspirin Over-the-Counter After Hip Replacement?
No. Never adjust or discontinue your medication without consulting your doctor. Over-the-counter aspirin should not be used as a substitute for the medication your doctor has prescribed. They will adjust dosage and duration based on your specific needs and recovery.
What are the Side Effects of Aspirin?
Common side effects of aspirin can include stomach upset, nausea, heartburn, and bleeding. These side effects should be reported to your doctor. Rare but serious side effects can include allergic reactions and internal bleeding.

They will work with you to determine the best course of action for your specific situation. Your individual needs and risk factors will determine the precise duration of your aspirin therapy after a hip replacement surgery, regardless of whether it includes a valve replacement.
