IVF Medication Injections: A Patient’s Guide

IVF injections help several eggs develop, control the timing of ovulation and, in some treatment plans, support the uterine lining. Your fertility team chooses the medicines and teaches you how to use them safely; this IVF injection guide explains the main steps, everyday precautions and symptoms that need medical attention.

For many couples, the first injection feels like a big emotional milestone. Feeling nervous does not mean you are unprepared. At PRAVI IVF & Fertility Centre, Kanpur, you can discuss your concerns and ask for practical instructions before beginning treatment.

Why are injections needed during IVF?

In a usual menstrual cycle, one egg generally matures. During IVF, fertility medicines encourage several follicles, the small fluid-filled sacs in the ovaries that contain eggs, to grow. This allows the doctor to plan egg retrieval before ovulation occurs.

Not every follicle contains an egg, and not every egg will be mature. Injections support the treatment process, but they cannot guarantee pregnancy. Your age, ovarian reserve, medical history and response to treatment help determine your prescription.

Types of IVF injections and what they do

Ovarian stimulation injections

These medicines contain follicle-stimulating hormone, sometimes with luteinising hormone activity, to encourage follicle growth. They are usually given daily for roughly one to two weeks, although the exact duration varies. Many are injected under the skin using a pen device or syringe.

Your doctor may adjust the dose after monitoring. A higher dose is not automatically better, and another patient's prescription is not a useful comparison.

Medicines to prevent early ovulation

Medicines called GnRH antagonists or agonists help control the body's hormone signals so eggs are not released before retrieval. Depending on the protocol, these may begin before stimulation or be added during it. Some protocols use a nasal preparation rather than an injection.

The trigger injection

The trigger helps eggs complete their final maturation. It may contain hCG, a GnRH agonist or a combination, depending on your treatment plan and safety needs.

Its timing is especially important because egg retrieval is scheduled around it, commonly about 34–36 hours later. Follow the exact time provided by your clinic, even if it falls late in the evening. Do not calculate or change the timing yourself.

Progesterone support

After egg retrieval, progesterone is commonly prescribed when a fresh embryo transfer is planned. It may be given as injections, vaginal preparations or other prescribed formulations. Frozen embryo transfer cycles have their own medication plans, and some do not need ovarian stimulation injections.

Do not stop progesterone because of spotting, symptoms or a home pregnancy test unless your doctor instructs you. Read more about medication support during IVF and early pregnancy.

What happens before you start?

Your team will review your medical history and relevant investigations, which may include an ultrasound and hormone tests. Tell them about allergies, existing health conditions, previous reactions to medicines, and all supplements or other treatments you use.

Before leaving with your prescription, ask for a written schedule showing the medicine name, dose, route and timing. Request a demonstration using the same device you will use at home, then repeat the steps back to the nurse.

• Confirm which medicines require refrigeration.
• Ask whether each injection goes under the skin or into a muscle.
• Save the clinic's contact details and ask about after-hours support.
• Check what to do if a dose is missed, spilled or given incorrectly.

A safe routine for injections at home

Many patients give their own under-the-skin injections after training, or ask a trained partner to help. Injections into a muscle may require a trained caregiver or healthcare professional. Always follow the instructions for your particular medicine and device.

• Wash your hands and arrange supplies on a clean surface.
• Check the medicine name, prescribed dose, expiry date and appearance.
• Prepare or mix the medicine only as demonstrated.
• Use the recommended injection site and rotate sites as instructed.
• Clean the skin as advised and allow it to dry before injecting.
• Use a new sterile needle and syringe where applicable; never share devices.
• Place used needles directly into an approved sharps container, not loose household waste.
• Record the dose and time immediately afterwards.

If you are unsure whether the full dose went in, do not automatically inject another dose. Contact the team for advice.

Storage in Kanpur's summer heat

Storage rules differ between products and can change after opening or mixing. Follow the package instructions and your pharmacist's advice rather than assuming every fertility medicine belongs in the fridge.

Keep medicines away from sunlight, hot vehicles and children. Never freeze medicines that require refrigeration. For travel or a power cut, ask how to maintain the required temperature; avoid direct contact with ice packs. If storage conditions are uncertain, check before using the medicine.

Why scans and blood tests matter

Ultrasound scans show how follicles are growing. Blood tests may also be used to assess hormone levels. Together, these help your doctor decide whether to adjust medication, schedule the trigger or change the treatment plan for safety.

Attend monitoring appointments even if you feel well. Symptoms alone cannot show whether your ovaries are responding as expected. Our guide to follicular monitoring during IVF explains this stage in more detail.

Common side effects and warning signs

Mild stinging, a small bruise, temporary redness, bloating, headache or breast tenderness can occur. Hormonal changes and treatment stress may also affect mood. Mention symptoms at your appointments and contact the clinic sooner if they worsen.

Ovarian hyperstimulation syndrome, or OHSS, is an excessive response to stimulation that can cause enlarged ovaries and fluid shifts. Your team monitors your response and may change the trigger or postpone embryo transfer to reduce risk.

Contact your clinic urgently for:

• Increasing abdominal pain or marked swelling.
• Persistent vomiting or difficulty keeping fluids down.
• Passing much less urine or rapid weight gain.
• Fever or spreading redness around an injection site.

Seek emergency care for breathing difficulty, chest pain, fainting, sudden severe pelvic pain, or facial or throat swelling. Do not wait for a routine appointment. OHSS symptoms can begin or worsen after egg retrieval, including during early pregnancy.

Missed doses, discomfort and everyday life

If you miss an injection, take the wrong dose or give the trigger at the wrong time, contact your clinic immediately with the medicine name and timing. Do not double a dose or try to correct the schedule yourself.

A relaxed position and allowing cleaned skin to dry may make injections more comfortable. Ask before using ice, numbing products or pain medicines. Report significant pain rather than assuming you must tolerate it.

Gentle activity is often comfortable, but enlarged ovaries can make vigorous exercise, jumping or twisting unsuitable. Ask about exercise and intercourse during stimulation. There is no special food or home remedy that replaces prescribed medicines or monitoring.

You do not have to manage everything alone

A shared calendar, phone reminders and a quiet injection routine can reduce daily stress. Partners can help organise supplies and attend demonstrations without taking control away from the person receiving treatment. Find more ideas in our guide to partner support during IVF.
