Susten 400 Softgel Capsule is used for supporting pregnancy in women undergoing fertility treatment and providing hormone replacement therapy by delivering 400mg of natural progesterone. Manufactured by Sun Pharmaceutical Industries Ltd, this bioidentical hormone helps maintain the uterine lining necessary for embryo implantation and early pregnancy support, making it essential for women experiencing female infertility or requiring progesterone supplementation. Patients exploring comprehensive women's health solutions often consider Clofi 100mg (Clomiphene) for ovulation induction, while those needing different progesterone strengths may find Susten SR 200mg appropriate for maintenance therapy. The softgel capsule formulation ensures optimal absorption and bioavailability, providing consistent hormone levels crucial for reproductive health outcomes.
Dosage & How to Take Susten 400 Softgel Capsule
Take Susten 400 Softgel Capsule exactly as prescribed by your fertility specialist or gynecologist, typically once or twice daily depending on your treatment protocol. The 400mg capsule is commonly administered vaginally or orally, with vaginal administration often preferred during fertility treatments for direct uterine exposure. Insert the softgel capsule deep into the vagina using clean hands before bedtime if using vaginally, or swallow whole with water if taking orally. For assisted reproductive technology cycles, treatment usually begins after ovulation or embryo transfer and continues through the first trimester if pregnancy occurs. Never adjust your dosage without medical supervision, as progesterone levels must be carefully maintained during early pregnancy. Your healthcare provider will monitor your response through blood tests and ultrasound examinations to ensure appropriate hormone support.
Is Susten 400 Softgel Capsule Right for You?
Susten 400 Softgel Capsule is safe for most women undergoing fertility treatment or requiring hormone replacement therapy under medical supervision. This medication is particularly appropriate for women with luteal phase defects, those undergoing IVF or IUI procedures, women with recurrent pregnancy loss due to progesterone deficiency, or postmenopausal women requiring hormone supplementation. You should not use this medication if you have undiagnosed vaginal bleeding, known or suspected breast cancer, active thromboembolic disorders, or severe liver disease. Women with a history of depression, diabetes, or cardiovascular conditions should inform their healthcare provider before starting treatment. Patients requiring additional fertility support may benefit from NeoHCG 10000 (HCG) for triggering ovulation. Common side effects include drowsiness, breast tenderness, bloating, and mood changes. Contact your doctor immediately if you experience severe abdominal pain, sudden vision changes, or signs of allergic reaction.

Your doctor will determine if this medication is right for your specific condition. Always follow your healthcare provider's instructions.

Follow your healthcare provider's specific instructions carefully.
How long does Susten 400 Softgel Capsule take to work?
Susten 400 begins working within hours of administration, but noticeable effects depend on why you're taking it. For pregnancy support, it works immediately to maintain hormone levels. For menstrual regulation, you may need several weeks of treatment to see results. Continue taking it for the full duration prescribed by your doctor, even if you feel better. Don't stop suddenly without medical advice.
Is Susten 400 Softgel Capsule safe to use?
Susten 400 is generally safe when used as prescribed by a doctor. However, it may cause side effects like drowsiness, dizziness, headache, or breast tenderness.

Report any unusual symptoms to your healthcare provider immediately.
Can I buy Susten 400 Softgel Capsule online without a prescription?
Susten 400 is a prescription medication that should only be purchased with a valid doctor's prescription.

They will evaluate your condition, determine appropriate dosage, and monitor your treatment for safety and effectiveness.

Progesterone for Luteal Phase Support: Why the Route Changes Everything
Vaginal progesterone gives serum levels that look low while putting roughly eight times more hormone into the endometrium than an injection does, and raising the dose does not raise the blood level. Route by route dosing, the endometrial versus serum numbers, what 26,198 randomised women showed about choosing between injection and vaginal, and why dydrogesterone will not show on a progesterone test.

Provera and the Progestin Withdrawal Bleed: What Bleeding, or Not Bleeding, Actually Tells You
A progestin course to bring on a missed period is a diagnostic test, not just a treatment. Bleeding proves estrogen, a responsive endometrium and an open outflow tract all at once; no bleeding sends the investigation somewhere else entirely. Label doses for medroxyprogesterone and micronized progesterone, the response rates behind them, and why the pregnancy test comes first.

The hCG Trigger Shot: Dose, the 36 Hour Window, and When It Stops Faking a Positive Test
The trigger shot starts a 34 to 36 hour clock that ends at retrieval, which is why clinics give the time to the minute. Dose equivalence across urinary and recombinant products, why 500 mcg bought more hyperstimulation and no more pregnancies than 250 mcg, the clearance data behind how long the injection keeps faking a positive test, and the FDA position on hCG for weight loss.
