Susten SR 200 mg (Progesterone) Tablet

Introduction About Susten SR 200 mg Tablet

Susten SR 200 mg (progesterone) is an oral sustained-release progesterone capsule. Progesterone is a natural hormone involved in the menstrual cycle and in preparing the uterine lining (endometrium).

When your body is not making enough progesterone, or when a medical plan calls for additional support, a prescriber may use progesterone to help create a more stable, predictable hormone pattern.

What “SR” means and why it matters

SR stands for sustained release. Instead of releasing the full dose quickly, an SR capsule is designed to release progesterone more gradually over time. For some patients, that can mean steadier coverage through the day or night. It can also affect how and when side effects show up.

Because SR products are made to release slowly, they should not be crushed, chewed, or opened unless a pharmacist specifically confirms it is safe for that exact product.

Common reasons progesterone may be prescribed

Your specific reason for taking progesterone depends on your medical history and goals; however, progesterone capsules like Susten SR 200 mg are commonly used in the following situations:

• Hormone therapy support: In some hormone therapy plans, progesterone is used to help protect the uterine lining when estrogen is part of treatment for people who still have a uterus.
• Irregular cycles or luteal phase concerns: Progesterone may be used on certain cycle days to support the second half of the cycle, based on your clinician’s schedule.
• Fertility care protocols: Some fertility treatment plans include progesterone support. The dose and duration can be very specific, so it is important not to adjust it without guidance.

If your prescription directions feel unclear, ask what cycle day to start, how long to continue, and what to do if bleeding starts sooner than expected.

How Susten SR 200 mg works in the body

Progesterone helps shift the uterine lining into a more “secretory” (supportive) state after ovulation. In simplified terms, it helps the lining stay stable instead of breaking down early.

In a medication plan, that stability is sometimes the point of treatment, whether it is to manage bleeding patterns, support a hormone regimen, or follow a fertility protocol.

Typically, Susten SR 200 mg (progesterone) is taken as prescribed by your doctor.

Susten SR 200 mg (progesterone) dosing is individualized. Some people are instructed to take progesterone once a day, often in the evening, because it can cause sleepiness in some patients.

Others may be told to take it for a set number of days per month, or on a timed schedule, as part of fertility care.

Do not change brands, strengths, or dosing schedules on your own. With hormones, small changes in timing can lead to unexpected spotting, cycle changes, or altered treatment results.

Possible side effects to know about

Many people tolerate progesterone well, but side effects can happen, especially when starting or changing a dose. Possible side effects include:

• Drowsiness or fatigue
• Dizziness
• Headache
• Breast tenderness
• Bloating or stomach discomfort
• Mood changes
• Spotting or changes in the bleeding pattern (depending on your treatment plan)

Contact your prescriber promptly if you have severe symptoms, chest pain, sudden shortness of breath, one-sided leg swelling, yellowing of the skin or eyes, or heavy bleeding. These are not common, but they need urgent medical review.

Please share key precautions and your medical history.

Progesterone is not a fit for everyone. Make sure your prescriber knows if you have had blood clots, stroke, liver disease, unexplained vaginal bleeding, or a history of hormone-sensitive cancers.

Also share a complete medication list, including supplements, because hormone plans are often adjusted around other therapies.

Substitute Options Available in the Market

Do not substitute progesterone products without clinician approval. Switching from sustained-release to immediate-release, or from oral to vaginal progesterone, can change absorption and clinical effect.

Potential alternatives your clinician may consider include:

• Susten 8% Vaginal gel (Progesterone)
• Generic micronized progesterone capsules
• Prometrium (micronized progesterone)
• Utrogestan (micronized progesterone, availability varies)
• Vaginal progesterone products used in fertility care, such as:

• Crinone (progesterone vaginal gel)
• Endometrin (progesterone vaginal insert)

• Other progestins are used in specific situations (not the same as progesterone and not interchangeable without guidance), such as:

• Medroxyprogesterone acetate (Provera)
• Norethindrone products

If a substitute is needed due to availability, side effects, or cost, ask your clinician what changes (if any) are expected in timing, symptom control, or monitoring.

FAQs

1. Is Susten SR 200 mg the same as “bioidentical progesterone”?

Progesterone is often described as bioidentical when it is chemically the same as the hormone made by the body. Whether a specific brand uses micronized progesterone and how it is formulated depends on the product label. If that detail is relevant for your care, ask the pharmacist to confirm the exact ingredient and formulation.

2. Can Susten SR 200 mg affect hormonal birth control?

It can. Adding progesterone may influence blood patterns and complicate how symptoms are interpreted. Do not combine it with birth control or change contraception plans unless your prescriber tells you to.

3. Is it safe to use progesterone if I have migraines?

Some people notice migraine pattern changes with hormone shifts. This is individualized. Please inform your prescriber about your migraine history to help them select the safest approach and dosing schedule.

4. Does this medication contain peanut oil or soy?

Some progesterone products use oils or specific excipients in the capsule. Ingredients vary by manufacturer. If you have peanut, soy, or other serious allergies, check the full ingredient list on the package and confirm with a pharmacist before taking it.

5. Will progesterone show up on a drug test?

Routine employment drug screens typically do not test for progesterone. If you are in a monitored program with specialized hormone testing, ask what is included in the panel and share your prescription documentation.
