In women’s health and fertility care, progesterone sustained release (SR) tablets have become an important treatment. These tablets help release the hormone slowly over time, matching how the body normally works.
But what are they really used for? Who should take them — and who should avoid them? Let’s break it down in a simple and clear way.
What Are Progesterone Sustained Release Tablets?
Progesterone SR tablets are hormone medicines that release progesterone slowly through the day. This helps keep your hormone level steady and gives better results for problems like irregular periods or pregnancy support.
Doctors often give these tablets for:
- Fertility treatments (like IVF or IUI)
- Missed periods
- Hormone replacement during menopause
- Early pregnancy support
Why Is Progesterone Important?
Progesterone is a natural hormone that helps with regular periods and pregnancy. It thickens the womb lining and helps keep a pregnancy in its early weeks.
If your body doesn’t make enough progesterone, you might face:
- Irregular or missed periods
- Trouble getting pregnant
- Early miscarriage
Sustained release progesterone tablets give your body the hormone it needs in a steady way.
What Are These Tablets Used For?
1. Fertility Support (IVF/IUI)
After ovulation or embryo transfer, progesterone helps the womb prepare for a baby and hold the pregnancy.
2. Early Pregnancy Loss
It helps relax the womb muscles and keeps the lining strong, lowering the risk of miscarriage.
3. PCOS and Missed Periods
In women with PCOS or missed periods, progesterone helps trigger a normal monthly bleed.
4. Menopause Support (HRT)
Women on estrogen therapy after menopause also need progesterone to protect the womb lining.

What Is Sustained Release Tablets?
Sustained release (SR) tablets are special types of medicines that slowly release the drug in your body over many hours. Instead of taking the same medicine 2–3 times a day, these tablets work for a long time with just one or two doses.
These tablets have a special outer layer or formula that controls how fast the medicine is released. This helps keep the amount of medicine in your blood steady, which can give better results and fewer side effects.
SR tablets are used for health problems like high blood pressure, diabetes, low mood (depression), and hormone problems. For example, progesterone sustained release tablets are often given to women to help during pregnancy or to fix hormone imbalances. They release the hormone slowly, just like the body’s natural way.
Benefits of SR tablets:
- You take them less often
- Better control of symptoms
- Easy to follow the treatment
But remember: Do not crush or chew SR tablets. Breaking them can release too much medicine at once and may harm you. Always take them whole, with water, and follow your doctor’s advice.
Sustained release tablets make treatment simple, steady, and safe when used the right way.
