Product introduction

SustEN 8% Gel should be inserted deep into the vagina exactly as prescribed. Use the medicine regularly and at the same time each day to maintain consistent support during early pregnancy. Treatment should always be guided by a doctor, and any ongoing bleeding or new symptoms should be reported promptly, as further evaluation may be required.


Most women tolerate SustEN 8% Gel well. Rarely, local side effects such as mild vaginal irritation, itching, burning sensation, or oily discharge may occur. These effects are usually mild and short-lived. If symptoms become bothersome or persistent, consult your doctor.


SustEN 8% Gel should be used only during the first trimester for the prevention of miscarriage. Any vaginal bleeding should always be investigated before and during treatment. The medicine should not be used in women with undiagnosed vaginal bleeding, severe liver disease, hormone-dependent cancers, thromboembolic disorders, or known allergy to progesterone or any ingredient in the product.

Uses of SustEN Vaginal gel

  • Prevention of Miscarriage

Benefits of SustEN Vaginal gel

Prevention of Miscarriage
SustEN 8% Gel helps in the prevention of miscarriage, especially in women who experience bleeding in early pregnancy and have a history of recurrent pregnancy loss. It supports the pregnancy by maintaining the uterine lining, helping the womb stay relaxed, and creating a favourable environment for the developing embryo. Vaginal administration delivers progesterone directly to the uterus, ensuring effective local action with lower exposure to the rest of the body. This helps improve the chances of continuing the pregnancy and provides reassurance and stability during a critical early phase of pregnancy.

Side effects of SustEN Vaginal gel

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
Common side effects of SustEN
  • No common side effects seen

How to use SustEN Vaginal gel

This medicine is for external use only. Use it in the dose and duration as advised by your doctor. Check the label for directions before use. Clean and dry the affected area and apply the gel. Wash your hands after applying

How SustEN Vaginal gel works

SustEN 8% Gel supports early pregnancy by acting on the uterus to maintain a healthy uterine lining needed for pregnancy to continue. It helps relax the uterine muscles, improves blood flow between the uterus and placenta, and reduces inflammatory and immune responses that could threaten the pregnancy.

Quick tips

  • Insert SustEN 8% Gel deep into the vagina while lying down, preferably at bedtime, to reduce leakage and help the medicine stay in place longer.
  • Use the medicine at regular times every day to maintain consistent hormonal support during early pregnancy.
  • Avoid skipping doses, especially during the first trimester, as this is a crucial period for supporting pregnancy.
  • Inform your doctor immediately if vaginal bleeding increases, becomes painful, or is accompanied by cramps or fever.
  • Avoid using other vaginal products such as douches, creams, or pessaries unless specifically prescribed, as they may interfere with treatment.
