It is generally recommended to avoid aspirin and other blood thinners before flying after egg retrieval if you have ovarian hyperstimulation syndrome (OHSS). After egg retrieval, especially with OHSS, your ovaries are enlarged and there's an increased risk of bleeding and clotting complications. Aspirin, being a blood thinner, can increase bleeding risk. Most fertility specialists advise waiting at least 1-2 weeks after egg retrieval before flying, and longer if you have OHSS symptoms. The pressure changes and immobility during flights can potentially worsen OHSS symptoms and increase clotting risks.
Instead of taking aspirin, stay well-hydrated, move your legs frequently if you must fly, wear compression stockings, and follow your doctor's specific instructions regarding activity restrictions and medication use. Your fertility clinic may recommend alternative approaches to prevent blood clots if necessary. Always consult with your fertility doctor before taking any medications or planning travel after egg retrieval, as they can provide personalized advice based on your specific situation and OHSS severity. According to a recent study 1, aspirin is generally as safe as low-molecular-weight heparin for preventing thromboembolic events among patients undergoing orthopedic surgery; however, aspirin can increase the risk of deep vein thrombosis.
Some key points to consider:
- The risk of OHSS and associated complications should be carefully evaluated before flying after egg retrieval 2.
- Aspirin may not be the best option for preventing blood clots in patients with OHSS, and alternative approaches should be considered 3, 1, 4.
- Staying hydrated, moving legs frequently, and wearing compression stockings can help reduce the risk of blood clots during flights.
- It is essential to follow the specific instructions of your fertility doctor regarding activity restrictions and medication use after egg retrieval.
