IVIG and Recurrent Pregnancy Loss: What Families Should Know

An honest look at the evidence, the questions to ask, and what home infusion involves if your doctor prescribes it

Lately our office has been getting calls from women and families asking about IVIG after repeated pregnancy loss. Many have read about it online or heard about it from a friend. Some have already talked with a specialist. Almost all of them are carrying a lot of grief and a lot of hope at the same time.

Those calls deserve a careful, honest answer. So here is what we know, what is still uncertain, and what to ask. One thing up front: we are a nursing company. We do not prescribe IVIG or decide who should receive it. That decision belongs to you and your reproductive specialist.

What is recurrent pregnancy loss?

The American Society for Reproductive Medicine (ASRM) defines recurrent pregnancy loss as the loss of two or more pregnancies. The losses do not have to be in a row to warrant an evaluation.

If this is your story, you are not alone, and it is not your fault. ASRM's 2026 guidance also carries a hopeful fact: 50 to 80 percent of people with RPL go on to have a successful pregnancy, even without medical treatment.

ASRM recommends starting with a focused evaluation. That can include chromosome testing of pregnancy tissue when possible, testing guided by your history, screening for conditions such as thyroid disease and diabetes, and emotional support and counseling. In many cases no cause is found. Doctors call that "unexplained" RPL, and it is where questions about immune treatments usually come up.

What is IVIG?

IVIG, or intravenous immunoglobulin, is made from antibodies collected from the donated plasma of thousands of healthy donors. It is given through an IV, usually over several hours.

IVIG is FDA approved for conditions such as primary immunodeficiency and certain autoimmune and neurologic disorders. It is not FDA approved for recurrent pregnancy loss. When a doctor prescribes it for RPL, that is an "off label" use. Off label prescribing is legal and common in medicine, but it means the FDA has not reviewed the evidence for this purpose.

Why has IVIG been studied for RPL?

Pregnancy depends on a delicate balance in the immune system. Researchers have long asked whether some unexplained losses involve that balance going wrong, and whether a treatment that acts on the immune system could change the outcome. IVIG has been studied with that question in mind for more than 30 years.

What does the research show?

The honest answer is that the evidence is mixed, and the question is not settled.

• A 2014 Cochrane review pooled 8 trials of IVIG involving 303 women. It found no significant difference in live births compared with placebo.
• A 2015 trial in women with secondary RPL (losses after a prior birth) and at least four losses found no significant difference in live births.
• A 2022 trial from Japan studied 102 women with four or more unexplained losses and no prior live birth. They received high doses of IVIG for five days, starting very early in pregnancy. The researchers reported more ongoing pregnancies and live births in the IVIG group than in the placebo group.
• After that trial, the European Society of Human Reproduction and Embryology (ESHRE) updated its guideline. It now says high dose IVIG very early in pregnancy may improve live birth rates in women with four or more unexplained losses. It calls this a conditional recommendation based on one trial, and it says more research is needed.
• ASRM's 2026 guidance advises against the routine use of treatments that lack strong evidence of benefit.

What does that mean for you? It means experts disagree, the research is still developing, and results from one group of patients in one trial may not apply to anyone else. A reproductive specialist who knows your history is the right person to weigh it with you.

Questions to ask your doctor

• What has my evaluation found, and is my RPL considered unexplained?
• Do I fit the group of patients that was studied? How many losses, and was there a prior birth?
• What are the possible benefits and risks for me specifically?
• When would treatment start, how often, and for how long?
• What are the alternatives, including no treatment?
• Will my insurance cover it? Many plans consider IVIG for RPL experimental, so ask for a benefits check before you start.
• Where would infusions happen: a clinic, an infusion center, or at home?

What are the risks?

IVIG is a powerful medication with real risks. All immune globulin products carry an FDA boxed warning for blood clots, and IVIG products also carry one for kidney problems. Pregnancy already raises the risk of clots, which is one more reason this decision needs a careful conversation with your specialist.

More common side effects include headache, chills, flushing, muscle aches, nausea, and tiredness. Many are related to how fast the infusion runs and ease when it is slowed down.

If your doctor prescribes IVIG: what home infusion looks like

If you and your doctor decide on IVIG, a specialty pharmacy prepares the medication and a registered nurse can give it in your home.

At every DOMO Health visit, the nurse:

• Checks the order, the product, and your dose against your current weight
• Takes your vital signs before, during, and after the infusion
• Starts slowly and increases the rate only if you are tolerating it
• Watches closely for reactions and carries emergency medication every time
• Documents every detail and reports back to your pharmacy and care team

For many families, getting treatment at home means less time in waiting rooms and less disruption at an already hard time.

How DOMO Health fits in

DOMO Health is a nurse led specialty home infusion company. Our registered nurses are trained and competency validated in IVIG administration, and they work with our specialty pharmacy partners when a prescriber orders home infusion.
