If you’re starting IVF and have been prescribed Meriofert, you’re likely staring at a box of syringes, vials, and alcohol wipes thinking, “How am I going to inject this?”

You’re not alone. In this post, I’ll walk you through exactly what Meriofert is, how it’s used in IVF stimulation, and what it actually feels like to inject it each day. Whether you're preparing for your first cycle or just curious about what’s ahead, this is for you.

What Is Meriofert?

Meriofert PFS 900 IU is a type of menotrophin — a hormone medication used to stimulate the ovaries during IVF. It contains FSH (follicle-stimulating hormone) and LH (luteinising hormone), two key hormones your body naturally produces to mature eggs.

When used in IVF, it helps your ovaries produce multiple follicles, rather than just one, to increase your chances of retrieving mature eggs for fertilisation.

Meriofert is part of the stimulation phase in IVF and is injected subcutaneously (just under the skin) — usually in the lower belly.

What Comes in the Box?

As shown in the image, a standard Meriofert PFS 900 IU kit includes:

• Sealed sterile syringes and needles

• Pre-filled vials of Meriofert powder and solvent

• Alcohol prep pads (for cleaning the skin)

• A pharmacy label with your exact dose and instructions

It must be stored in the fridge (2–8°C) — so make sure you’re keeping it cool!

Your IVF Clinic Will Personalise the Dose

Your clinic may adjust your dosage based on:

• AMH levels

• Antral follicle count (AFC)

• Age and response in previous cycles

• Risk of OHSS (Ovarian Hyperstimulation Syndrome)

How to Prepare and Inject Meriofert

1. Wash your hands and clean the surface

2. Wipe your belly with an alcohol pad (usually 2–3 inches below your belly button)

3. Mix the powder and solvent (as instructed by your clinic or pharmacist)

4. Draw the solution into the syringe

5. Pinch the skin and insert the needle at a 45–90° angle

6. Inject slowly, then remove and dispose of the needle safely

7. Apply gentle pressure if needed, and rotate injection sites daily

It might sound complicated, but after a couple of days, many people feel more confident. Some even find it helpful or empowering to take control of the process.

What It Feels Like (Emotionally & Physically)

You may feel:

• Overwhelmed at first — especially handling needles (but get used to it very quickly - I was so scared in the beginning, but when I realised you hardly feel anything it got easier)

• Tenderness or bruising at the injection site (try switching the sites each day)

• Hormonal mood swings from rising oestrogen levels

• Bloating or pressure as follicles grow

But you’re also likely to feel proud, capable, and resilient. Taking injections daily is no small task. You’re doing something brave — every single day.

Storage Tips

• Keep Meriofert in the fridge (never in the freezer)

• Take it out about 10 minutes before injecting to let it warm slightly

• Don’t shake the solution when mixing — gently swirl instead

• If you’re travelling, use a cool bag or fridge-safe pouch. (You find a good one here)

Cost & Where It Comes From

In the UK, Meriofert is often prescribed by your IVF clinic and dispensed by a fertility pharmacy. It’s not usually something you buy over the counter.

If you’re doing IVF on the NHS, it may be included in your funded cycle. If you’re going private, this medication may cost £250–£400 per box depending on the dose.
