Kliogest (Norethisterone Acetate, Estradiol)

Norethisterone acetate, the active ingredient in Kliogest, is a combined estrogen‑progestogen presented as an oral tablet for oral administration. Together with estradiol, it provides both estrogen and progestogen activity to replace declining endogenous hormones, helping to alleviate menopausal vasomotor symptoms and to prevent ovulation for contraception. It also contributes to the maintenance of bone mineral density, which is important in post‑menopausal women.

GNH India supplies Kliogest as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring quality and regulatory conformity for global distribution.

Indications & Clinical Uses

Kliogest, a combined estrogen‑progestogen, is used in therapeutic areas that involve hormonal regulation.

  • Menopausal symptom relief: Reduces hot flashes, night sweats and improves quality of life in peri‑ and post‑menopausal women.
  • Osteoporosis prevention: Helps maintain bone mineral density and reduces risk of fractures in post‑menopausal patients.
  • Contraception: Suppresses ovulation and stabilizes the endometrium to provide reliable combined oral contraceptive protection.

How It Works

  • Norethisterone acetate is a synthetic progestogen that binds to progesterone receptors, while estradiol is a bioidentical estrogen that activates estrogen receptors (ERα and ERβ). The combined action supplies exogenous hormone levels that replace the decline of endogenous estradiol and progesterone during menopause and, when used as a contraceptive, the progestogenic component inhibits the mid‑cycle LH surge, preventing ovulation, and the estrogen component stabilizes the endometrial lining.

Side Effects

Kliogest may be associated with a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

  • Nausea: mild stomach upset.
  • Headache: transient tension‑type headaches.
  • Breast tenderness: swelling or discomfort.
  • Irregular vaginal bleeding: spotting or breakthrough bleeding.

Serious or Rare Side Effects

  • Venous thromboembolism: deep vein thrombosis or pulmonary embolism.
  • Stroke: ischemic or hemorrhagic cerebrovascular events.
  • Severe allergic reaction: anaphylaxis or angioedema.

Precautions & Warnings

Before prescribing Kliogest, clinicians should consider several precautionary measures to ensure patient safety.

  • Assess cardiovascular risk: evaluate history of thrombosis, stroke, or myocardial infarction.
  • Screen for hormone‑dependent cancers: avoid use in active breast, endometrial or ovarian cancer.
  • Monitor liver function: contraindicated in severe hepatic impairment.
  • Counsel on smoking: advise against use in women over 35 who smoke.
  • Review concomitant medications: consider interactions with anticoagulants or enzyme inducers.
  • Store at ambient temperature: keep tablets below 25 °C in the original container, protected from moisture.

Avoid Interactions

Kliogest can interact with other medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid)

  • Strong CYP3A4 inducers (e.g., rifampicin, carbamazepine): may reduce hormonal levels and contraceptive efficacy.
  • Anticoagulants (e.g., warfarin): increased risk of thrombotic events when combined with estrogen.

Moderate Interactions (Monitor Closely)

  • Antiepileptic drugs (e.g., phenytoin, phenobarbital): may decrease hormone concentrations.
  • Antifungal agents (e.g., ketoconazole): may increase hormone levels, raising side‑effect risk.
  • Selective serotonin reuptake inhibitors (SSRIs): may exacerbate mood changes.

Frequently Asked Questions

Kliogest is a combined estrogen‑progestogen oral tablet indicated for relief of menopausal symptoms such as hot flashes and night sweats, for prevention of post‑menopausal bone loss, and as a combined oral contraceptive to inhibit ovulation and stabilize the endometrium.

Norethisterone acetate acts as a synthetic progestogen binding to progesterone receptors, while estradiol activates estrogen receptors. Together they replace declining endogenous hormones, suppress the mid‑cycle luteinizing hormone surge to prevent ovulation, and provide estrogenic support to maintain bone density and alleviate vasomotor symptoms.

The specific dosing regimen for Kliogest is determined by the prescribing clinician based on the individual’s therapeutic indication, age, medical history, and concomitant medications. Patients should follow the prescriber’s instructions and not alter the dose without medical advice.

Kliogest is contraindicated in pregnancy because the estrogen and progestogen components can affect fetal development. It is generally not recommended during breastfeeding unless the benefits outweigh the risks, and this decision should be made by a healthcare professional.

To order Kliogest, submit an enquiry on the product page at gnhindia.com with the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and the necessary import documentation.

Kliogest contains norethisterone acetate and estradiol, whereas many other combined oral contraceptives use ethinyl‑estradiol as the estrogen component. Estradiol is a natural estrogen, which may offer a different side‑effect profile, particularly regarding estrogen‑related metabolic effects, while still providing effective ovulation suppression.

Kliogest tablets should be stored at ambient temperature, preferably below 25 °C, in the original packaging to protect them from moisture and light. Do not store in a bathroom or near heat sources, and keep out of reach of children.

Kliogest is taken orally, usually once daily at the same time each day, with or without food, as directed by the prescribing clinician. Consistent daily intake helps maintain stable hormone levels and ensures optimal therapeutic effect.

The most serious risks include venous thromboembolism, stroke, myocardial infarction, and severe allergic reactions such as anaphylaxis. Patients with a history of cardiovascular disease, smoking, or hormone‑dependent cancers should be evaluated carefully before initiating therapy.

Kliogest is contraindicated in women with active breast, endometrial or ovarian cancer, uncontrolled hypertension, a history of thromboembolic disorders, severe liver disease, or known hypersensitivity to its ingredients. It should also be avoided in pregnant women and in smokers over 35 years of age.
