Orgalutran for IVF: Dosing, Storage and How It Compares to Cetrotide
- Orgalutran (ganirelix 0.25 mg) is a daily shot that stops you from ovulating too early during IVF stimulation.
- Most patients start it around day 5 or 6 of stimulation and take it every day until trigger day.
- Orgalutran doesn’t need a fridge. Keep it below 86°F (30°C) and never freeze it.
- Each prefilled syringe is ready to use, so there’s no mixing.
Orgalutran for IVF has one job: it keeps your eggs from being released before your doctor can retrieve them. It comes as a small prefilled syringe that you inject under the skin once a day. Here’s how it works, when you start it, how to store it and how it compares to Cetrotide.
What Does Orgalutran for IVF Do?
Contents
During stimulation, medications like follitropin alfa help several follicles grow at once. As those follicles get bigger, your body may try to release LH, the hormone that starts ovulation. If that happens too soon, the eggs can be lost before retrieval.
Ganirelix, the active ingredient in Orgalutran, blocks that early LH surge. Doctors call it a GnRH antagonist. It works within hours, which is why clinics can add it in the middle of a cycle. The European Medicines Agency keeps the official Orgalutran product information if you want the full details.
When Do You Start Orgalutran for IVF?
Most clinics start Orgalutran for IVF on day 5 or 6 of stimulation. Others wait until your lead follicle reaches about 12 to 14 mm on ultrasound. You then inject 0.25 mg once a day, at about the same time each day.
You keep taking it until your doctor tells you to give the trigger shot. Your last dose is usually the morning of trigger day or the day before. Many patients use 4 to 6 syringes per cycle, though your own count depends on how your follicles grow. After that, a trigger like the Ovidrel trigger shot finishes egg maturation.
A few tips for each shot:
- Inject into the belly, at least an inch from your belly button
- Switch sides each day to reduce soreness
- Don’t push out the small air bubble in the syringe
- Tell your doctor if you have a latex allergy, the needle cover on some syringes contains latex
Does Orgalutran Need to Be Refrigerated?
No. Unlike many shots, Orgalutran for IVF is stored at room temperature, below 86°F (30°C). Don’t freeze it, and keep the syringes in their box to protect them from light. That makes it easier to handle than many other IVF medications.
Generic ganirelix brands can have different storage rules, so always read the label on your box. If you’re flying during a cycle, our guide on traveling with IVF medications explains how to pack shots in your carry-on.
Is Orgalutran Better Than Cetrotide?
Both medications do the same job and work about equally well. The main differences are practical. Orgalutran comes ready to inject. Cetrotide comes as a powder you mix with water before each shot.
| Orgalutran (ganirelix) | Cetrotide (cetrorelix) | |
|---|---|---|
| Dose | 0.25 mg daily | 0.25 mg daily |
| Form | Prefilled syringe | Powder plus solvent |
| Mixing needed | No | Yes |
| Storage | Room temperature | Check your box, many need a fridge |
