Progesterone 400 mg – Product Overview

Progesterone 400 mg represents a pharmaceutical‑grade soft gelatin capsule that has been specifically formulated by Sanzyme Biologics (P) Ltd. for use in the management of female infertility and as an adjunct component of hormone replacement therapy. Each blister pack contains ten soft gelatin capsules, each delivering a standardized dose of 400 milligrams of micronized progesterone. The product is offered in three convenient pack sizes — 100 capsules, 200 capsules, and 300 capsules — allowing clinicians, pharmacies, and patients to select the quantity that best fits their treatment protocol and usage patterns. The capsules are designed for oral administration and are packaged to preserve stability and potency throughout the shelf life.

What is Progesterone 400 mg?

Progesterone is a naturally occurring steroid hormone that plays a central role in the regulation of the menstrual cycle, preparation of the uterine lining for implantation, and the maintenance of early pregnancy. In clinical practice, micronized progesterone is utilized to supplement deficient levels in women who experience luteal phase insufficiency, irregular ovulation, or other hormonal imbalances that impede conception. The 400 mg soft gelatin capsule provides a micronized, highly bioavailable form of the hormone that is efficiently absorbed after oral ingestion, delivering a consistent plasma concentration that mimics the physiological luteal surge. This formulation is intended for use under the supervision of a qualified healthcare professional and is not intended for self‑diagnosis or over‑the‑counter purchase.

Uses and Benefits

The therapeutic applications of Progesterone 400 mg are broad and include, but are not limited to, support of ovulation induction protocols, endometrial preparation in assisted reproductive technologies such as in‑vitro fertilization (IVF), and the treatment of luteal phase deficiency. When combined with estrogen in hormone replacement regimens, progesterone protects the endometrial lining from estrogen‑induced hyperplasia, thereby reducing the risk of abnormal endometrial proliferation and potential cancerous changes. Patients who use the medication as part of a comprehensive fertility plan often experience improved cycle regularity, increased implantation rates, and higher clinical pregnancy outcomes. U.S. Food and Drug Administration (FDA) recognizes progesterone as a key component of hormone replacement therapy. Beyond reproductive health, Progesterone 400 mg has been investigated for its role in alleviating menopausal symptoms such as hot flashes, night sweats, and mood fluctuations. Additionally, adequate progesterone levels have been associated with supportive effects on bone mineral density when paired with calcium and vitamin D supplementation, making it a valuable component in holistic women’s health strategies.

How It Works

The biological activity of progesterone is mediated through intracellular progesterone receptors that regulate gene transcription involved in reproductive physiology. The micronized form in the soft gelatin capsule enhances dissolution and absorption, ensuring that steady-state plasma concentrations are achieved within a predictable timeframe. This pharmacological profile enables the hormone to thicken the endometrial lining, improve uterine receptivity, and sustain the early stages of pregnancy by preventing premature shedding of the uterine lining. The controlled release characteristics of the capsule also contribute to a lower peak concentration and a more gradual decline, which can translate into fewer side‑effects compared with immediate‑release formulations.

Dosage Guidelines

Dosage of Progesterone 400 mg must be individualized by a licensed healthcare provider based on the patient’s specific clinical situation, response to prior therapies, and any underlying medical conditions. In fertility treatment protocols, a typical regimen involves the oral administration of one capsule daily for a defined period, often beginning on a predetermined day of the menstrual cycle and continuing until a pregnancy test is performed or until the prescribed duration is completed. For hormone replacement therapy, the prescribing clinician may adjust the frequency and duration according to symptom control, laboratory monitoring, and coexisting therapies. Patients are strongly advised to adhere strictly to the dosing instructions provided on the prescription label. If a dose is missed, the patient should not double the next dose but should contact their physician for guidance. Regular follow‑up appointments and laboratory assessments are recommended to evaluate hormone levels and monitor for any adverse effects.

Side Effects

Like all pharmaceutical agents, Progesterone 400 mg may be associated with side effects, although many are mild and transient. The most commonly reported adverse events include abdominal bloating, breast tenderness, mild headache, and occasional nausea. Less frequent but clinically significant reactions can involve mood changes, dizziness, or breakthrough uterine bleeding. Although rare, serious adverse events such as allergic reactions, thromboembolic events, or hepatic dysfunction require immediate medical attention. Patients should report any new or worsening symptoms promptly.

Warnings and Precautions

Progesterone 400 mg is contraindicated in individuals with a known hypersensitivity to the drug or any of its excipients, as well as in patients with a history of estrogen‑dependent malignancies, unexplained vaginal bleeding, or active thromboembolic disorders. Caution should be exercised in patients with hepatic or renal impairment, as well as in those with a history of cardiovascular disease, because these conditions may influence drug metabolism and elimination. National Institutes of Health (NIH) provides detailed information on hormone safety. Concurrent use of other medications, particularly estrogen agonists, selective estrogen receptor modulators, or anticoagulants, may necessitate dosage adjustments or additional monitoring. Pregnant or breastfeeding women should only use the medication under the explicit direction of a physician, as the safety profile during these states requires careful evaluation. It is essential that all patients discuss their complete medical history and current medication list with their prescribing clinician before initiating therapy.

Frequently Asked Questions
