Medical Conditions Treated with Susten 200
Here are some common medical conditions where It is used:
1. Luteal Phase Support in Fertility Treatment
In IVF (In Vitro Fertilization) and IUI (Intrauterine Insemination), doctors prescribe Susten 200 after ovulation or embryo transfer to prepare the uterus and maintain pregnancy.
2. Threatened or Recurrent Miscarriages
Low progesterone levels can cause the uterine lining to shed prematurely. Susten 200 helps by maintaining the lining and giving the embryo a stable environment.
3. Hormone Replacement Therapy (HRT)
In menopausal women undergoing estrogen therapy, it balances the effects of estrogen and prevents uterine lining thickening (endometrial hyperplasia).
4. Irregular Periods / Secondary Amenorrhea
If your periods are irregular or absent (especially due to hormonal imbalance), it will help restore the cycle.
5. Endometriosis
Progesterone can reduce the growth of endometrial tissue and ease symptoms like pain and heavy bleeding.

Susten is available in different forms based on the patient’s needs:
- Susten 200 Capsules – oral or vaginal use
- Susten Gel – vaginal application
- Susten Injection – intramuscular use for stronger support

🧴 Which form is best?

Mechanism of Action: How Does Susten 200 Work?
Progesterone prepares the endometrium (uterine lining) to receive and nourish the fertilized egg. It prevents the uterus from contracting and ensures a pro-pregnancy environment.
In non-pregnancy cases, it helps regularize hormonal imbalances by mimicking natural progesterone activity.

- If you’re using it vaginally, lie down for 15–20 minutes afterward to ensure proper absorption.
- Take it at the same time every day to maintain consistent hormone levels.
- Don’t stop suddenly — follow your doctor’s instructions on when to taper or stop.
