How Susten SR 300 Tablet Works

Progesterone is a natural female hormone that prepares and maintains the uterine lining (endometrium) for implantation and pregnancy. It stabilizes the endometrium, reduces uterine contractions, and supports the luteal phase when endogenous progesterone is inadequate.

Dosage & Directions

Oral sustained-release tablet; take exactly as prescribed, preferably at the same time each day. Usually taken after food and often at bedtime (may cause drowsiness/dizziness). Swallow whole; do not crush or chew. Duration and dose depend on indication (luteal support/pregnancy support/amenorrhea).

Always follow your doctor's prescription. Do not self-medicate.
