What Is Progestan 100 MG?
Progestan 100 MG is a micronized progesterone capsule used to support pregnancy during IVF treatment and other assisted reproductive procedures. Progesterone is a hormone your body naturally produces. During IVF, your clinic often prescribes supplemental progesterone to prepare the uterine lining for embryo implantation and to maintain early pregnancy.
Progestan is manufactured by Kocak Farma and is available in capsule form. It can be taken orally or vaginally, depending on what your doctor instructs. The 100 MG dose is most commonly used during the luteal phase of an IVF cycle or after a frozen embryo transfer (FET).
How Is Progestan 100 MG Used in IVF?
Your reproductive endocrinologist will tell you when to start, how much to take, and how long to continue. Most women take Progestan at bedtime to reduce dizziness. Dosing schedules vary — some clinics prescribe a single 100 MG capsule daily, others use multiple doses depending on the IVF protocol.
When used vaginally, Progestan capsules bypass the liver and may absorb more efficiently. Do not change your route of administration without speaking to your doctor first.
Progestan 100 MG is the European brand equivalent of Prometrium, Cyclogest, and Progynex. If your clinic has prescribed any of these, Progestan covers the same need. Fast IVF also carries Progestan 200 MG for patients who require a higher dose.

Progestan 100 MG is generally well-tolerated. The most common side effects include:
- Dizziness or drowsiness (most common when taken orally)
- Breast tenderness
- Nausea or bloating
- Fatigue
- Headache
Taking Progestan at bedtime helps reduce drowsiness. If you experience severe side effects, contact your healthcare provider right away. According to the NIH, progesterone supplementation during IVF is safe and well-studied when used as directed.
