Surrogate medication protocols vary by fertility clinic, transfer type, and medical history. Do not use a Resource page as a medication schedule. Your fertility clinic should give you the exact medication names, doses, timing, injection or application instructions, monitoring plan, and stop dates.
Why medications may be used
In a gestational surrogacy cycle, medications may be used to prepare the uterine lining, synchronize timing, support embryo transfer, and support early pregnancy. SART explains that ART cycles can include hormone support for the uterine lining and that medicated frozen embryo transfer cycles often use estradiol and progesterone supplementation.
Your protocol may look different from another surrogate's protocol. Clinics adjust instructions based on ultrasound findings, bloodwork, embryo timing, prior response, and transfer plan.
Medications you may hear about
Depending on the protocol, the clinic may discuss:
- Estrogen or estradiol to support uterine-lining preparation.
- Progesterone after transfer or around transfer timing.
- Prenatal vitamins or supplements recommended by the clinician.
- Cycle-synchronization medications in some protocols.
- Antibiotics, aspirin, or other medications only if specifically prescribed.
Some medication names are common in ART, but that does not mean every surrogate takes them. The only correct medication list is the one issued by your treating clinic.
What monitoring may involve
Monitoring may include ultrasound checks, bloodwork, lining measurements, medication adjustments, pregnancy testing, and early ultrasound follow-up. After pregnancy is established, the clinic may continue certain medications for a defined period and then transition care to an OB/GYN or pregnancy care team.
If you miss a dose, inject at the wrong time, spill medication, have side effects, or are unsure about instructions, contact the clinic immediately. Do not self-correct without clinical guidance.
Questions to ask your clinic
- What is each medication for?
- How and when do I take it?
- What side effects should I report?
- What should I do if I miss or delay a dose?
- Which pharmacy fills the prescription?
- Who pays for the medication and supplies?
- When do I stop each medication?
- Who is available after hours for urgent medication questions?
Medication organization tips
Keep the written protocol, pharmacy labels, supply list, sharps instructions, and clinic phone numbers together. Confirm whether medications need refrigeration, whether injections require specific supplies, and how refills are handled before you run low. If travel is required around transfer, ask the clinic how to pack medication and what to do if a dose will fall during a flight, hotel stay, or appointment day.
Do not compare your protocol with another surrogate's protocol as if one must be wrong. Different clinics and transfer plans can use different timing, medications, and monitoring. What matters is that your instructions are clear to you and documented by your treating team.
How Patriot Conceptions can help
Patriot Conceptions can help organize reminders, pharmacy coordination, reimbursement documentation, and communication between the surrogate and clinic. The agency cannot change medication instructions. Medication decisions belong to the fertility clinic and treating providers.
