Intralipid

An IV infusion that may support embryo implantation

What is Intralipid?

Intralipid is a fat emulsion used as an intravenous nutritional supplement. In fertility treatment, it is used to improve the chances of embryo implantation and pregnancy.

How does Intralipid work?

  • Immune system modulation: Intralipid helps regulate your immune system. This can help patients who have elevated natural killer (NK) cell activity, which can hinder embryo implantation.
  • Nutritional support: it provides essential fatty acids, which are important for cellular function and overall health.

How it’s given

  • Preparation: Intralipid is given through an intravenous (IV) infusion.
  • Duration: the infusion typically takes about 2 hours.
  • Frequency: you will have 3 doses. The first is 1 week before your transfer, the second is 1 week after your positive hCG, and the third is at your 7-week ultrasound scan.

Possible side effects

Most patients tolerate Intralipid well, but some may have side effects. Common side effects include:

  • Mild reactions: headache, dizziness, fever or chills.
  • Infusion site reactions: pain, redness or swelling where the IV goes in.

Allergic reactions are rare, but some patients may have a rash, itching or difficulty breathing. Tell your healthcare provider immediately if you have these symptoms.

On the day

Please bring a laptop, a book or something to keep you busy for the 2 hours. We will give you some food and drinks during the infusion. Wear a shirt that rolls up easily or gives us access to your elbow for the IV.
