Susten gel 8.0% is widely prescribed in gynaecology and reproductive medicine for luteal phase support, infertility treatment, hormonal imbalance, and menstrual regulation by bypassing the digestive system. The prescription-strength topical progesterone gel is formulated to deliver natural micronised progesterone directly through the skin for effective absorption. Progesterone is an essential female hormone that regulates the menstrual cycle, prepares the uterus for pregnancy, and supports early pregnancy. In women with progesterone deficiency, supplementation is often necessary to maintain hormonal balance and reproductive health. Susten gel provides targeted hormonal support with fewer systemic side effects than oral progesterone. When your body doesn’t produce enough of this hormone, menstrual irregularities may occur. Susten gel may be prescribed to increase your progesterone levels. Susten gel 8% is also used as part of the treatment program for women undergoing ART (Assisted reproductive Technology), and your gynaecologist has determined that your body is not able to produce an adequate amount of progesterone on its own. Progesterone gel may be given to increase your progesterone. Once the woman conceives, Susten gel may be supplemented for 10 to 2 weeks until the placenta's progesterone production is adequate. Susten Gel contains 8% w/w Progesterone, a bioidentical hormone that mimics the progesterone naturally produced by the ovaries. When applied topically, the gel is absorbed through the skin into the bloodstream, enabling steady, controlled hormone delivery. 

Progesterone plays a critical role in:

• Thickening and stabilising the uterine lining (endometrium)
• Supporting implantation of a fertilised egg
• Preventing premature uterine contractions
• Balancing estrogen dominance
• Regulating menstrual cycles

This makes Susten Gel particularly useful in IVF cycles, assisted reproductive techniques (ART), and hormone replacement therapy (HRT).

Susten Gel offers several benefits over oral or injectable progesterone:

• Direct absorption through the skin
• Avoids first-pass liver metabolism
• Reduced gastrointestinal side effects
• Consistent hormone levels
• Easy, painless application
• Better patient compliance

Because of these advantages, topical progesterone gels are increasingly preferred in modern gynaecological practice.

How to Use Susten Gel 8.0%

Susten gel is a reliable solution for women requiring consistent progesterone supplementation as part of fertility or hormonal treatment plans. Use only under medical supervision. Dosage and duration depend on your medical condition and treatment protocol. Read the instructions for use included in your prescription carefully. Generally, one needs to apply to clean, dry skin and allow it to absorb completely. Do not wash the area for at least 1–2 hours after application. Wash your hands thoroughly after use. Common application sites include the lower abdomen, thighs, arms, or shoulders.

What precautions should be taken?

Do not start using Susten gel if you are allergic to progesterone, progesterone-like medications, or any of the inactive ingredients in the gel. Inform your gynaecologist if you have liver disease, cancer of genital organs, breast cancer, unexplained vaginal bleeding, or have had a miscarriage and some tissues still left in the uterus or have had blood clots in the lungs or elsewhere. Avoid self-medication during pregnancy. Keep the medication out of reach of children.
