Susten 8% Vaginal gel (Progesterone)

Introduction About Susten 8% Vaginal gel (Progesterone)

Susten 8% Vaginal gel (Progesterone) is a prescription progesterone gel used for luteal phase support, often during assisted reproductive treatment.

It delivers progesterone locally through the vagina using a prefilled applicator. Your clinician will set the schedule, commonly once daily.

Typical effects can include vaginal discharge, bloating, breast tenderness, or headache.

What this gel is and why the vaginal route is chosen

This gel contains progesterone for vaginal use. Many clinicians prefer this route as it delivers strong local exposure to the uterus and often causes fewer body-wide effects. Systemic symptoms can still occur, and responses vary.

Common uses

Susten 8% Vaginal gel (Progesterone) is most often prescribed for:

• Luteal phase support in assisted reproductive techniques (such as IVF or similar protocols)
• Progesterone supplementation is used when a clinician determines progesterone support is needed during a fertility cycle.

Indications can vary by diagnosis and treatment. If unsure why it was prescribed, ask your clinician, as “progesterone support” means different things depending on timing and goals.

Typical dosing approach

Your prescriber will tell you how to use it. Many fertility protocols use 8% gel once daily at a set time. Some schedules differ by labs or clinic protocol. Do not change dose or timing on your own.

How to use it

• Use as directed and read the included instructions.
• Many people find that using the gel at bedtime can reduce the inconvenience of leakage.
• Some vaginal discharge or residue is common with progesterone gel and does not mean the dose failed. If concerned about the amount, ask your clinic.
• If you forget a dose, follow your prescriber’s instructions. If you can’t reach them, take it when remembered unless it’s close to your next dose. Do not double-dose unless told to do so.

What you may feel (side effects)

Some side effects are due to progesterone; some stem from the vaginal route.

Possible effects include:

• Vaginal discharge, irritation, or itching
• Breast tenderness
• Bloating
• Headache
• Mood changes or tiredness

Contact a clinician promptly if you have symptoms that may indicate an allergic reaction, such as hives, swelling of your face, lips, tongue, or throat, chest pain, shortness of breath, sudden severe headache, swelling or pain in a leg, severe pelvic pain, or heavy or unusual vaginal bleeding. These symptoms need urgent assessment, even if they may turn out to be unrelated.

Who should be cautious?

Your prescriber should check your history first. Progesterone isn’t suitable for everyone, especially with some cancers, unexplained vaginal bleeding, liver disease, or a history. Always provide your full medication and supplement list.

Storage basics

Store as directed on the package. Avoid heat exposure.
