Deltacortril for IVF: 5 Key Facts You Need to Know
Quick Summary
- Deltacortril (prednisolone) is a low-dose steroid used in some IVF protocols to support implantation.
- It calms the immune system so the body is less likely to reject the embryo.
- Typical dose: 5–10 mg/day, often starting a few days before embryo transfer.
- Short-term use at these doses is well-tolerated for most patients.
- Order Deltacortril 5mg directly from Fast IVF — European-sourced, fast shipping.
Deltacortril ivf use has quietly become a standard add-on in many reproductive clinics. You might see it on your protocol sheet and wonder why a steroid is part of your IVF cycle. Here’s what you need to know.
What Is Deltacortril?
Contents
Deltacortril is a brand name for prednisolone, a synthetic corticosteroid. It belongs to the same family as prednisone and cortisone. In everyday medicine it’s used for arthritis, allergies, and autoimmune conditions because it reduces inflammation and dampens immune responses.
In IVF, it serves a more targeted purpose — helping the uterus accept an embryo without triggering an immune reaction.
Why Do Some IVF Clinics Use Deltacortril?
Here’s the core idea: your immune system is designed to recognize foreign cells. An embryo — which carries genetic material from a partner — can sometimes trigger that response. Deltacortril lowers the immune activity in the uterine lining, which may reduce the chance of the body rejecting the embryo before it can implant.
Clinics use it most often for patients with:
- Repeated implantation failure
- Elevated uterine natural killer (uNK) cell levels
- Autoimmune conditions like thyroid disease or lupus
- Thin or inflamed endometrial lining
Not every clinic includes it in standard protocols, the evidence is still mixed, but it’s a common addition for higher-risk cases. Learn more about how IVF protocols work in our guide to the IVF process.
What Deltacortril Dosage Is Used in IVF?
The most common dose is 5 mg once daily. Some protocols use 10 mg, and a few go higher for specific immune conditions. Timing usually looks like this:
- Start: 2–5 days before embryo transfer (or earlier in some protocols)
- Duration: Through the two-week wait, then tapered if pregnancy is confirmed or stopped after a negative result
- Form: Oral tablet — Deltacortril 5mg tablets are the most widely used form
Always follow your clinic’s exact instructions. Do not change the dose without talking to your doctor first.
Does Deltacortril Improve IVF Success Rates?
Studies show mixed results. Some trials found that prednisolone improved implantation rates in patients with elevated uNK cells or multiple failed cycles. Others showed no benefit in unselected patients. A 2019 Cochrane review noted limited evidence either way.
The bottom line: it’s used selectively, not universally. If your doctor prescribes it, there’s a specific reason based on your test results and history. Pair it with good lifestyle habits — see our 10 tips for a successful IVF cycle for practical guidance.

What Are the Side Effects of Deltacortril in IVF?
At the low doses used in IVF — 5 to 10 mg for a few weeks — most patients don’t notice much. Common mild effects include:
- Slightly increased appetite
- Mild mood changes or difficulty sleeping
- Minor fluid retention
- Stomach upset (taking it with food usually solves this)
Serious side effects are rare at these doses and durations. The risks associated with corticosteroids — like bone density loss or blood sugar spikes — apply to long-term high-dose use, not to a short IVF cycle. If you have diabetes, hypertension, or a history of peptic ulcers, flag this before starting.

Frequently Asked Questions
Is Deltacortril the same as prednisone?
They’re closely related but not identical. Prednisolone (Deltacortril) is already in its active form, while prednisone must be converted by the liver first. Both are corticosteroids and produce similar effects — many protocols use them interchangeably, but prednisolone is preferred for patients with liver conditions.
When do I start taking Deltacortril for IVF?
Most protocols start it 2–5 days before embryo transfer. Some clinics begin it earlier in the cycle. Follow your clinic’s timeline exactly — timing matters.
Can I stop Deltacortril suddenly after embryo transfer?
Don’t stop without checking with your doctor. A short taper is usually recommended even at low doses. If you get a positive result, your doctor will likely keep you on it for the first trimester then taper gradually.
Does Deltacortril affect a pregnancy test?
No. Prednisolone does not affect hCG levels, which is what pregnancy tests detect. It won’t cause a false positive or false negative.
Do I need a prescription for Deltacortril?
Yes — it’s a prescription medication. Your reproductive endocrinologist will prescribe it if it’s part of your protocol. Fast IVF requires a valid prescription for dispensing.
