IVF Blood Thinner

Blood Thinning Injections (Anticoagulants) in IVF Treatment

What are Blood Thinning Injections?

Blood thinning injections used in IVF treatment are generally from the low molecular weight heparin (LMWH) group (e.g., enoxaparin). The aim is to reduce blood clotting and support the embryo's attachment to the uterus.

For What Purpose are They Used?

• To prevent microclot formation
• To improve endometrial blood flow
• To support implantation
• To reduce risk in certain immune and clotting problems

Who Needs Them?

• Thrombophilia (clotting disorder)
• Recurrent pregnancy loss
• Recurrent IVF failure
• Antiphospholipid syndrome
• Certain selected high-risk patients

Is Routine Use Necessary?

No. It is not routinely recommended for every IVF patient. It is only beneficial in the appropriate patient group.

When are They Started?

They are usually started on the day of or after embryo transfer. In some cases, they may be started earlier.

How are They Used?

They are administered as daily subcutaneous injections. The dose is determined according to the patient.

Side Effects

• Bruising at the injection site
• Mild bleeding tendency
• Rarely, serious bleeding

Risks

The risk of bleeding may increase with overdose or incorrect use. Therefore, medical supervision is essential.

When are They Discontinued?

If pregnancy occurs, they are usually continued into the first trimester or as per doctor's recommendation. Individual planning is required.

Clinical Fact

Blood thinners are only beneficial in a specific patient group. Unnecessary use does not provide benefit and may pose a risk.

Conclusion

Blood thinning injections are supportive treatments used in selected patients during IVF treatment. Correct patient selection is critically important.
