IVF Medications: A Complete Guide to Every Drug in Your Protocol

When your fertility clinic hands you a list of medications for your IVF cycle, it can feel like you're reading a foreign language. Gonal-F, Menopur, Cetrotide, Lupron, Ovidrel, progesterone in oil. So many names, so many needles. This guide breaks down every category of IVF medication so you feel informed and prepared.

Important: This guide is educational. Your doctor prescribed your specific protocol for a reason. Always follow their instructions for dosages and timing.

Category 1: Gonadotropins (Stimulation Drugs)

These are the heavy lifters of your IVF cycle. Gonadotropins stimulate your ovaries to produce multiple follicles (each containing an egg) instead of the single egg your body would normally release.

Gonal-F (follitropin alfa)

One of the most commonly prescribed stimulation drugs. It comes in a multi-dose pen or single-use prefilled syringe. Gonal-F is a recombinant FSH (follicle-stimulating hormone), meaning it's lab-made to be identical to the FSH your body naturally produces.

Administration: Subcutaneous injection (belly or thigh). Storage: Refrigerate before first use. After opening the pen, it's good for 28 days at room temperature or refrigerated. Common side effects: Bloating, injection site reactions, mood swings, headaches.

Menopur (menotropins)

Menopur contains both FSH and LH (luteinizing hormone). Some protocols use it alone, others combine it with Gonal-F or Follistim. Menopur requires mixing with sterile water before injection.

Administration: Subcutaneous injection. Storage: Room temperature before mixing, use immediately after. Side effects: Similar to Gonal-F, plus the mixing step can be stressful. Take your time. Watch your clinic's instruction video as many times as you need.

Follistim (follitropin beta)

Very similar to Gonal-F, Follistim is another recombinant FSH. It comes in a cartridge that loads into the Follistim Pen. Your doctor chooses between Gonal-F and Follistim based on their preference and your insurance coverage, as they're therapeutically similar.

Category 2: GnRH Antagonists (Preventing Premature Ovulation)

Once your follicles start growing, your body might try to ovulate too early. Antagonists prevent this.

Cetrotide (cetrorelix) and Ganirelix

These are essentially interchangeable. You'll start one of them around day 5 to 7 of stimulation, when your leading follicles reach about 14mm. They block the LH surge that would trigger ovulation.

Administration: Subcutaneous injection (belly). Storage: Room temperature. Side effects: Injection site redness, occasional headache. Generally well-tolerated.

Category 3: GnRH Agonists (Suppression)

Lupron (leuprolide acetate)

In "long protocol" or "Lupron down-regulation" cycles, you'll take Lupron for 1 to 2 weeks before starting stimulation. This suppresses your natural hormones so your doctor has complete control over the stimulation phase.

Lupron is also sometimes used as a trigger shot (instead of HCG) in patients at risk for OHSS (ovarian hyperstimulation syndrome).

Administration: Subcutaneous injection. Storage: Room temperature, protected from light. Side effects: Hot flashes, headaches, mood swings, fatigue. The suppression phase can feel like a mini-menopause, and it can be rough. You're not imagining it.

Category 4: Trigger Shots

The trigger shot is the most time-sensitive medication in your entire cycle. It triggers the final maturation of your eggs before retrieval. Your clinic will give you a specific time, sometimes down to the minute. Set multiple alarms.

Ovidrel (choriogonadotropin alfa)

A prefilled syringe of recombinant HCG. Subcutaneous injection, usually in the evening. No mixing required. This is the most convenient trigger option.

Pregnyl (HCG)

Requires mixing with sterile water. Intramuscular injection (typically the upper outer quadrant of the buttock). Having a partner or friend help with this injection is common and nothing to feel embarrassed about.

Category 5: Progesterone Support

After retrieval (or before a frozen transfer), you'll need progesterone to prepare and maintain your uterine lining for implantation. This continues through the first trimester if you become pregnant.

Progesterone in Oil (PIO)

The most common form. Intramuscular injection into the upper outer buttock. This is often the most dreaded medication because the needle is larger and the oil is thick. Tips: warm the vial in your hands or under warm water for 2 minutes. Use a heating pad on the injection site afterward. Alternate sides each day.

Endometrin (vaginal progesterone)

A vaginal insert used 2 to 3 times daily. Less painful than PIO but can be messy. Some clinics use this alone, others combine it with PIO.

Crinone (progesterone gel)

A vaginal gel applicator. Used once or twice daily. Similar to Endometrin in convenience and side effects.

Category 6: Supporting Medications

Estrace (estradiol)

Oral or vaginal estrogen used to build your uterine lining, especially in FET (frozen embryo transfer) cycles. Side effects include headaches, bloating, and breast tenderness.

Medrol (methylprednisolone)

A short course of steroid sometimes prescribed around transfer to reduce inflammation and support implantation. Usually just a few days.

Doxycycline

An antibiotic often prescribed to both partners before retrieval or transfer as a precaution.

Baby Aspirin

Low-dose aspirin (81mg) is commonly recommended to improve blood flow to the uterus.

Practical Tips for Managing All These Medications

• One tracking system: Don't scatter your schedule across apps, sticky notes, and your memory. Use one tool (TrackMyIVF was built for exactly this).
• Ice the injection site for 30 seconds before subcutaneous shots to reduce sting.
• Organize your fridge: Dedicate one shelf for IVF medications. Label opened dates.
• Travel kit: If you need to travel during stim, bring medications in an insulated bag with ice packs. Carry prescriptions in your name.
• Disposal: Use a sharps container for needles. Many pharmacies offer free disposal.
• Ask for help: Partners can learn to give injections. Nurses at your clinic can teach both of you. YouTube tutorials from fertility clinics are also helpful.

The Emotional Side of IVF Medications

Nobody talks enough about how IVF medications affect you emotionally. The hormones are real, and so are the feelings they amplify. You might cry at a commercial, snap at your partner over nothing, or feel inexplicably hopeless at 2am. This is not weakness. This is biochemistry layered on top of an already stressful situation.

Tell your support system what you're going through. If you're struggling, your clinic can adjust protocols. If you need to talk to someone, we've built crisis support directly into TrackMyIVF for the moments when it all feels like too much.

You're doing something incredibly brave. Every injection is an act of hope.
