Description
π Susten 100 mg (Progesterone)
Product Description
Natural Micronized Progesterone Supplement
Susten 100 mg is a prescription medication containing the hormone Progesterone.1 This formulation typically contains micronized progesterone, meaning the particles are very fine, which enhances the absorption and bioavailability of the hormone when taken orally or used vaginally.2
Progesterone is a naturally occurring female hormone vital for regulating the menstrual cycle and supporting pregnancy.3 It plays a critical role in preparing the lining of the uterus (endometrium) for implantation and maintaining it once pregnancy occurs.
The 100 mg dose is a standard strength used in various hormone replacement and fertility protocols.
Key Indications:
-
Luteal Phase Support (LPS): Used during assisted reproductive technologies (ART) such as IVF, to support the early stage of pregnancy by thickening the uterine lining.4
-
Preventing Threatened or Recurrent Miscarriage: Used to supplement low progesterone levels, which may contribute to early pregnancy loss.5
-
Hormone Replacement Therapy (HRT): Used in post-menopausal women to protect the uterine lining from the excessive growth (endometrial hyperplasia) that can be caused by estrogen therapy.6
-
Treatment of Menstrual Disorders: Used to treat secondary amenorrhea (absence of periods) caused by hormonal imbalance.7
Key Benefits:
-
Natural Hormone: Contains the same molecular structure as the progesterone naturally produced by the body.8
-
Versatile Administration: Can often be administered orally or vaginally/rectally, depending on the indication and required absorption profile.
-
Uterine Lining Support: Crucial for maintaining a healthy endometrium for implantation and pregnancy.9
π‘οΈ Precautions
Is Susten 100 mg Right for You?
Because progesterone is a hormone, its use must be carefully monitored, especially regarding potential cardiovascular or liver effects.
Please inform your doctor if the patient:
-
Has a History of Blood Clots: Strict Warning: Progesterone, especially when taken orally, may slightly increase the risk of blood clots in the legs (DVT), lungs (PE), or brain (stroke).10
-
Has Undiagnosed Vaginal Bleeding: Bleeding must be investigated before starting therapy.
-
Has a History of Liver Disease: Progesterone is metabolized by the liver, and severe liver impairment may be a contraindication.11
-
Has or is Suspected of Having Breast or Uterine Cancer: Hormone-dependent cancers are generally contraindications.12
-
Has a History of Depression: Progesterone can sometimes worsen depressive symptoms.13
-
Is Using Vaginally for Fertility: Be sure to follow the doctor’s instructions precisely regarding administration route, as the vaginal route achieves higher local uterine concentrations.
β οΈ Side Effects
Understanding Potential Reactions
Side effects are common and often relate to the hormone itself or the route of administration.
Common Side Effects (Often more prominent with oral use):
-
Drowsiness, sedation, or dizziness (often why oral doses are taken at bedtime).14
-
Headache.
-
Nausea, bloating, or abdominal discomfort.15
-
Breast tenderness.
-
Change in menstrual bleeding patterns.
Common Side Effects (Vaginal/Rectal use):
-
Local irritation, discharge, or burning.
Serious Side Effects (Seek medical attention immediately):
-
Signs of a Blood Clot: Sudden severe chest pain, shortness of breath, unexplained swelling/pain in the leg, or sudden severe headache/vision change.
-
Jaundice: Yellowing of the skin or eyes (sign of liver issues).16
-
Severe Allergic Reaction: Rash, hives, or swelling of the face, lips, or tongue.17
π How to Use
Guidelines for Effectiveness
The proper route and timing of administration are critical, especially in fertility treatment.
-
Dosage: Take the exact number of capsules prescribed. The dosage schedule is highly dependent on the indication (HRT vs. fertility).
-
Route of Administration: Crucial Step: Confirm with your doctor whether you are to take the capsule orally (by mouth) or vaginally. Do not switch routes without instruction.
-
Oral Use: Usually taken at bedtime, as the progesterone can cause sedation or dizziness.18 Take with a glass of water.
-
Vaginal Use: The capsule is inserted deep into the vagina, usually using a finger or an applicator (if provided). This route bypasses the liver and delivers the hormone directly to the uterus, often preferred in IVF.
-
Consistency: Take the medication at the same time(s) every day.
-
If You Miss a Dose: Take it as soon as you remember. If it is almost time for your next dose, skip the missed one. Do not double the dose.
-
Storage: Store at room temperature (below 19$30^\circ\text{C}$), protected from moisture.20
