What Are the Common IVF Medications?
IVF medications vary based on a person’s fertility history, how their body responds to treatment, and their specific needs. Throughout the IVF cycle, different medications are used at various stages to optimize the chances of success.
Dr. David Harari, M.D., emphasizes the importance of medication in IVF stimulation. “The medications in IVF stimulation are very important,” he says. “Generally, it starts with a pretreatment protocol, which is usually a birth control pill for about three weeks.”
This initial step helps regulate the menstrual cycle and prepare the ovaries for stimulation.
“Then we move on to several other categories of medications,” he continues, “called GnRH analogs or antagonists, gonadotropins, HCG—human chorionic gonadotropin—as a trigger shot, estrogen, and progesterone.”
Each plays an important role, from stimulating egg production to triggering ovulation and supporting implantation.
Ovarian Stimulation Medications
Ovarian stimulation medications encourage the ovaries to produce multiple eggs in a single cycle instead of just one. These drugs have follicle-stimulating hormone (FSH) and sometimes luteinizing hormone (LH). They help support follicle growth.
FSH drugs such as Gonal-F, Follistim, and Bravelle help follicles grow. Menopur and Repronex are frequently used in these cases.
Ovulation Trigger Medications
When the follicles mature, a trigger shot is given. This helps prepare the eggs for retrieval. These medications contain human chorionic gonadotropin (hCG), which mimics the body’s natural LH surge. This surge tells the eggs to finish maturing.
Common hCG-based trigger shots include Ovidrel, Pregnyl, and Novarel. These injections are typically given 36 hours before egg retrieval. This helps improve the chances of getting mature eggs.
Medications to Prevent Premature Ovulation
Doctors prescribe GnRH agonists or antagonists to prevent eggs from being released too early. These medications manage hormones from the pituitary gland. They prevent an early LH surge, helping eggs mature properly.
GnRH agonists, such as Lupron and Synarel, lower the body’s natural hormones. This happens before ovarian stimulation begins. GnRH antagonists, such as Cetrotide and Ganirelix Acetate, prevent early ovulation. This helps doctors manage ovarian stimulation better.
Luteal Phase Support Medications
After egg retrieval, luteal phase support medications ready the uterus for implantation. They also help maintain early pregnancy. Progesterone supplements play a key role in maintaining the uterine lining.
Common progesterone medications include:
- Crinone (vaginal gel)
- Endometrin (vaginal suppository)
- Prometrium (oral or vaginal capsule)
- Progesterone in Oil (PIO) injections.
Some patients might need estrogen medications. These include Estrace, which comes as a pill taken orally or vaginally, and Vivelle-Dot, an estrogen patch. These help support implantation.
Other Supportive Medications
Some IVF protocols include extra medications to improve implantation chances and reduce complications. Low-dose aspirin is sometimes recommended to increase blood flow to the uterus.
Antibiotics might be given after egg retrieval to lower infection risk. Steroids can also help reduce uterine inflammation and improve implantation success.
Administering IVF medications correctly is crucial for the success of an IVF cycle. Different IVF meds require different methods of administration. Most ovarian stimulation medications and ovulation trigger shots are injectables. Some hormone regulators, however, are taken by mouth. You can take progesterone support as vaginal suppositories. Estrogen therapy comes as transdermal patches. Each method plays a specific role in preparing the body for IVF.

Injectable IVF Medications
Most IVF prescriptions need injections. These can be subcutaneous (under the skin) or intramuscular (into the muscle).
- Subcutaneous injections are given into the fatty tissue, usually in the abdomen or thigh. This method works for FSH drugs, such as Gonal-F and Follistim. It also applies to GnRH antagonists, like Ganirelix. These injections use a short, thin needle and are relatively easy to self-administer. The injection site should be cleaned with an alcohol swab, and the needle should be inserted at a 45- to 90-degree angle.
- Intramuscular injections, like progesterone in oil (PIO) and hCG trigger shots, go into the muscle. They are usually given in the upper outer part of the buttocks. These require a longer needle and must be injected at a 90-degree angle. After administering the injection, gently massaging the area helps distribute the medication and reduce discomfort.
Oral Medications
Some IVF drugs are taken in pill form to regulate hormone levels before and after ovarian stimulation. Doctors may prescribe birth control pills to sync cycles before stimulation.
“The purpose of the oral contraceptives initially is to turn off the ovarian function,” explains Dr. David Harari, M.D. “So that when we take over artificially with our stimulation hormones through the IVF stimulation cycle, we can have you produce multiple eggs at one time and stimulate those follicles for egg retrieval.”
In addition to birth control pills, doctors may also prescribe Estrace (Estradiol) to thicken the uterine lining before embryo transfer.
In some cases, steroids like Dexamethasone help calm an overactive immune response, ensuring a more favorable environment for implantation.
Vaginal Suppositories and Transdermal Patches
For luteal phase support, doctors often use vaginal suppositories. Standard options include Crinone, Endometrin, and Prometrium. These medications help maintain the uterine lining and support implantation. Estrogen patches are another option, delivering a steady dose of hormones through the skin.
Sticking to the IVF Medication Schedule
Following the correct IVF medication schedule is essential. Timing is key for injectable medications. The hCG trigger shot, for example, should be given exactly 36 hours before egg retrieval. Missing a dose or taking medication incorrectly can impact treatment success.
Proper medication storage is also important. Some require refrigeration, while others should be kept at room temperature. Patients should always check the instructions provided by their fertility clinic. Many find it helpful to set alarms or reminders to ensure they stay on track with their treatment plan.
Administering meds for IVF can feel overwhelming at first, but with practice and guidance, it becomes more manageable. Fertility clinics provide step-by-step instructions, and nurses are available for support. Some patients find comfort in online forums. They can share experiences and tips with others facing the same process.
However, beyond managing the schedule and administration, the financial aspect of fertility medications can also be a challenge. Since IVF treatment often involves multiple medications, exploring ways to reduce fertility medication costs can help ease the financial burden while ensuring patients stay on track with their treatment plans.
Risks & Side Effects of IVF Medications
IVF medications can sometimes cause side effects. These range from mild discomfort to serious complications. Understanding these risks helps patients recognize what is expected and when to seek medical advice.
Common Side Effects of IVF Medications
Many patients experience mild to moderate side effects as their bodies adjust to IVF meds. These symptoms are typically temporary and subside once the cycle is complete.
Hormonal medications may lead to side effects. These include bloating, headaches, nausea, and breast tenderness. Some women also report mood swings and irritability due to fluctuating hormone levels.
Injection-site reactions are common with injectable medications. You may notice redness, swelling, or mild bruising. Using ice packs before injections and rotating injection sites can help minimize discomfort.
Some patients feel abdominal discomfort after an hCG trigger shot. This happens as the ovaries enlarge. This usually goes away after egg retrieval. However, if you have severe or lasting pain, you should tell your doctor.
Ovarian Hyperstimulation Syndrome (OHSS)
A more serious side effect of stimulation medications is ovarian hyperstimulation syndrome (OHSS). This condition happens when the ovaries react too much to the medication. This causes swelling and fluid build-up in the abdomen. OHSS symptoms can range from mild to severe.
Due to fluid retention, mild OHSS may cause bloating, nausea, and weight gain.
In moderate to severe cases, symptoms can include:
- Severe abdominal pain
- Rapid weight gain
- Vomiting
- Difficulty breathing
Severe OHSS needs medical help. Doctors closely watch hormone levels and follicle growth during an IVF cycle. This helps them adjust medications and lower the risk of OHSS.
Multiple Pregnancy Risks
IVF medications help more eggs mature. This increases the chances of having twins or triplets. Some couples see this as a good thing. However, multiple pregnancies carry risks. These include early birth, low weight at birth, and problems like gestational diabetes and preeclampsia. Many fertility experts recommend transferring only one embryo during IVF. This helps lower the risk.
Allergic Reactions and Uncommon Side Effects
Although rare, some patients may experience an allergic reaction to specific IVF prescriptions. Symptoms may include rashes, itching, dizziness, or difficulty breathing. If an allergic reaction occurs, medical attention is needed immediately.
Some women might notice changes in their menstrual cycle after stopping IVF medications. This can include delayed periods or irregular bleeding. These effects usually resolve as hormone levels return to normal.
Reducing Risks and Managing Side Effects
Drink enough water, rest well, and follow your IVF medication schedule. These steps can help manage your symptoms. Stay in touch with your fertility clinic to quickly address unusual or severe reactions.
Final Thoughts
IVF medications help regulate hormones and stimulate egg production. They also prevent early ovulation and support implantation. Each drug plays a specific role in optimizing the chances of a successful IVF cycle. The process might feel overwhelming. However, understanding how these medications work can help patients feel more prepared. Stick to the IVF medication schedule and talk with your fertility specialist.
