What should you know about embryo transfer medication?

Treatment plans may use hormones before or after transfer to coordinate the cycle and support the uterine lining. Progesterone may be supplied as a vaginal preparation, injection, or another form, depending on the clinic's protocol. Other medicines can be used to control cycle timing or prepare the endometrium. The right medicine, dose, route, and start date are personal to the cycle; do not compare schedules with another patient.

Keep a written schedule and follow the instructions for storage, application, and missed doses. If you vomit, miss a dose, cannot keep medicine down, or have trouble using the prescribed form, contact the clinic for specific advice rather than doubling the next dose. Keep the clinic informed about all other medicines, supplements, allergies, and new symptoms.

Ask for prompt medical advice about a suspected allergic reaction, severe headache with visual changes, severe pelvic pain, heavy bleeding, fever, faintness, breathlessness, or rapidly increasing abdominal swelling. Seek urgent help for swelling of the face or throat, collapse, or difficulty breathing. Do not stop prescribed support because of spotting without speaking to the clinic.

Ask what each medicine is for, when it starts and stops, and what to do after a missed dose. Confirm the route of administration, storage instructions, side effects worth reporting, and whether every medicine should continue after the pregnancy test.
