The Complete IVF Medication Guide: Every Injection Explained by a Fertility Nurse
If you’re starting IVF, chances are you’ve opened a box of medications and immediately felt overwhelmed.
Needles, vials, mixing powders, confusing names, medication schedules—it can feel like learning a whole new language overnight.
The good news?
Once you understand why you’re taking each medication, the process becomes much less intimidating.
As a Registered Nurse with more than 10 years of fertility experience, I’ve taught hundreds of patients how to safely prepare and administer their IVF medications. My goal is simple: to help you feel confident—not confused.
Let’s walk through each medication together.
Why Are IVF Medications Needed?
Your natural menstrual cycle usually matures one egg each month.
During IVF, fertility medications encourage your ovaries to mature multiple eggs at the same time. More eggs can increase the number of embryos available for fertilization and, in some cases, improve the chances of having embryos to transfer or freeze.
Each medication has a specific role in helping your cycle progress safely.
Menopur (Menotropins)
What is it?
Menopur contains both FSH (follicle-stimulating hormone) and LH (luteinizing hormone).
What does it do?
It stimulates multiple ovarian follicles to grow and mature.
How is it given?
A once-daily subcutaneous injection after mixing the powder with sterile saline.
Common side effects
Mild burning during injection
Bloating
Headaches
Bruising
Injection site redness
Fertility Nurse Tip
Menopur often stings. Let the medication sit for a minute after mixing and inject slowly to help reduce discomfort.
Follistim
What is it?
A laboratory-made form of FSH.
What does it do?
Encourages your ovaries to produce multiple follicles.
Given
Subcutaneous injection using a medication pen.
Common side effects
Bloating
Tender ovaries
Mild headaches
Injection site soreness
Fertility Nurse Tip
Rotate injection sites every day to reduce irritation.
Gonal-F
What is it?
Another form of FSH that works similarly to Follistim.
Purpose
Stimulates follicle growth.
Common side effects
Mild bloating
Fatigue
Pelvic pressure
Cetrotide
What is it?
A GnRH antagonist.
Purpose
Prevents your body from ovulating before your egg retrieval.
Common side effects
Itching
Redness
Small welts at the injection site
Fertility Nurse Tip
Some temporary redness after Cetrotide is common and usually resolves quickly.
Ganirelix
Ganirelix serves the same purpose as Cetrotide.
It prevents premature ovulation while your follicles continue developing.
Common side effects are nearly identical and usually mild.
Lupron
Purpose
Depending on your protocol, Lupron may be used:
Before stimulation
As part of your trigger
To help prevent ovarian hyperstimulation syndrome (OHSS)
Common side effects
Headache
Hot flashes
Mood changes
Fatigue
Ovidrel
What is it?
A trigger shot containing hCG.
Purpose
Triggers final egg maturation before retrieval.
Timing is extremely important. Take it exactly as instructed by your fertility clinic.
Pregnyl
Another hCG trigger medication.
Works similarly to Ovidrel and is often mixed from a powder before injection.
Novarel
Novarel is another hCG trigger shot used to prepare the eggs for retrieval.
Like other trigger medications, timing is critical because egg retrieval is typically scheduled about 34–36 hours later.
Progesterone in Oil (PIO)
Purpose
Supports the uterine lining after egg retrieval and embryo transfer.
Given
Intramuscular injection into the upper outer hip.
Common side effects
Muscle soreness
Bruising
Lumps
Stiffness
Fertility Nurse Tip
Applying warmth afterward and gently massaging the area may help reduce soreness. Follow your clinic’s instructions for warming the medication if recommended.
Vaginal Progesterone
Common forms include vaginal suppositories or gel.
These medications also help support the uterine lining during early pregnancy.
Estrace (Estradiol)
Purpose
Helps build and maintain a healthy uterine lining for embryo implantation.
May be taken as
Oral tablets
Vaginal tablets
Patches (depending on your clinic’s protocol)
Common IVF Medication Side Effects
Many patients experience:
Bloating
Fullness in the ovaries
Mood changes
Fatigue
Mild headaches
Breast tenderness
Bruising
Injection site redness
If you experience severe abdominal pain, significant shortness of breath, rapid weight gain, persistent vomiting, or heavy bleeding, contact your fertility clinic promptly, as these may be signs of a complication requiring medical evaluation.
Frequently Asked Questions
Do IVF injections hurt?
Most injections cause only brief discomfort. Menopur may sting more than others, while progesterone in oil often causes muscle soreness afterward.
What if I miss a dose?
Contact your fertility clinic as soon as possible. Do not double a dose unless your clinic specifically instructs you to do so.
Can I travel with IVF medications?
Many medications can travel safely, but some require refrigeration. Always review storage instructions for each medication and plan ahead if you’re flying or traveling long distances.
Is bruising normal?
Yes. Mild bruising and redness are common and usually resolve within a few days.
You Don’t Have to Figure This Out Alone
Starting IVF is emotional enough without wondering whether you’re mixing a medication correctly or giving an injection at the right time.
As a fertility nurse, I help patients understand their treatment plans, organize medication schedules, and feel more confident throughout the IVF process.
Whether you’re preparing for your first injection or simply want reassurance that you’re on the right track, I’m here to help.
