Susten 8% Vaginal gel (Progesterone)

Susten 8% Vaginal Gel, Explained Simply

Susten 8% Vaginal Gel is a prescription progesterone gel used to support the luteal phase and help stabilize the uterine lining. Doctors often include it in fertility plans like IVF or IUI, and sometimes for early pregnancy support when your own progesterone is not quite enough. It’s the same type of hormone your body makes—just delivered right where it’s needed. This is general information to help you understand the product. Always follow your own provider’s directions.

Where Susten 8% Commonly fits in

• Luteal phase support in IVF/ICSI, IUI, or timed cycles
• Early pregnancy support when a clinician confirms low progesterone or past luteal issues
• Endometrial stabilization when estrogen is used to build the lining in certain protocols

Your exact schedule depends on your history, lab results, and the plan your fertility team built for you.

How this Gel Supports Fertility Goals

After ovulation, your body should make enough progesterone to turn the uterine lining into a cozy, stable place for implantation. If levels drop too early or don’t rise enough the lining can break down or get spotty. Susten 8% adds back progesterone locally, which helps to:

• Thicken and stabilize the endometrium at the right time
• Support implantation in ART cycles as directed
• Balance estrogen’s effects on the uterus so things stay orderly

Step-By-Step Application Made Easy

Use only as your doctor prescribes. These are general, practical steps:

• Wash and dry your hands.
• Open one prefilled applicator as shown on its pack.
• Lie on your back with knees bent, or stand with one leg raised whatever’s comfortable.
• Gently insert the applicator high into the vagina.
• Press the plunger fully to release the gel.
• Remove and discard the single-use applicator. Do not flush.
• Stay lying down for 10–15 minutes if you can. A little leakage later is normal use a thin liner.

Tips:

• Try to apply it at the same times each day.
• Avoid tampons and other vaginal products (creams, douches) around dosing time unless your provider says otherwise.
• If you miss a dose, use it when you remember unless it’s close to the next one. Don’t double up unless told to.

Typical Dosing Patterns Your Clinic May Choose

Your plan is personal. Common examples in fertility care include:

• Once daily starting after ovulation, egg retrieval, or embryo transfer
• Sometimes twice daily for stronger luteal support
• Continued into early pregnancy if advised (often up to 10–12 weeks), then tapered off

Only your clinician can set the right start date, frequency, and stop date for you.

What You Might Feel Day to Day

Common, usually mild effects:

• Vaginal discharge or residue (the gel can thicken and exit later)
• Mild vaginal irritation, itching, or burning
• Breast tenderness or bloating
• Headache, nausea, or a bit of dizziness
• Sleepiness, though less common with the vaginal route than oral

Less common but serious get medical help right away:

• Signs of a blood clot (leg swelling/pain, chest pain, sudden shortness of breath)
• Severe headache, vision changes, trouble speaking, or weakness on one side
• Yellowing of skin/eyes, severe belly pain, or very dark urine (possible liver issue)
• Severe mood changes or depression
• Allergic reaction (rash, facial swelling, trouble breathing)

If a side effect is bothering you, tell your provider. A small schedule tweak can help a lot.

Who Should Pause and Talk to Their Doctor First

Do not use unless your clinician says it’s safe if you have:

• Unexplained vaginal bleeding not yet checked out
• Active or past blood clots, stroke, or serious liver disease
• Known or suspected breast cancer or other hormone‑sensitive cancers (unless your specialist clears it)
• Allergy to progesterone or any component of the gel/applicator

Pregnancy and breastfeeding:

• Early pregnancy use is common in fertility care but only continue if your provider instructs you to.
• If you become pregnant, do not stop suddenly without guidance.
• During breastfeeding, discuss risks and benefits with your clinician.

Medicine, Food, and Product Interactions to Know

Because Susten 8% is used vaginally, fewer drug interactions show up compared to oral dosing, but they can still happen.

• Strong enzyme inducers (like rifampin, carbamazepine, phenytoin, St. John’s wort) may lower hormone levels.
• Strong inhibitors (like ketoconazole, itraconazole, certain antibiotics such as clarithromycin) may raise levels.
• Estrogen products and other hormones should be balanced by your provider.
• Avoid other intravaginal products near dosing time unless your clinician okays them—they can interfere with absorption.

Storage, Handling, and Neat little Pointers

• Store at room temperature away from heat and moisture.
• Keep applicators in the original packaging until use.
• Single use only—discard after one application.
• Keep out of reach of children and pets.
• Keep a simple symptom log and bring it to appointments. It really helps fine‑tune your plan.
