Indications & Clinical Uses

Kliogest, an oral estrogen‑progestogen combination, is used in hormonal contraception to prevent pregnancy.

  • Contraception: prevents pregnancy by inhibiting ovulation and stabilising the endometrium.
  • Menstrual cycle regulation: reduces irregular bleeding and provides predictable cycles.
  • Acne treatment: decreases androgen‑driven acne by lowering circulating androgen levels.

How It Works

  • Norethisterone acetate binds to progesterone receptors, suppressing the mid‑cycle surge of luteinising hormone (LH) and follicle‑stimulating hormone (FSH), thereby inhibiting ovulation. Estradiol activates estrogen receptors, stabilising the endometrial lining and providing cycle control, while also contributing to the negative feedback on gonadotropin release.

Side Effects

Kliogest may cause a range of adverse reactions. Patients should be aware of both common and serious possibilities.

Common Side Effects

  • Nausea
  • Headache
  • Breast tenderness
  • Weight gain
  • Mood changes
  • Spotting or breakthrough bleeding

Serious or Rare Side Effects

  • Venous thromboembolism (deep‑vein thrombosis, pulmonary embolism)
  • Stroke or transient ischemic attack
  • Myocardial infarction
  • Severe hypertension
  • Hepatic adenoma or other liver disorders
  • Anaphylactic reaction or severe allergic response

Precautions & Warnings

Before prescribing Kliogest, clinicians should consider several safety factors.

  • Assess thrombotic risk: evaluate personal or family history of clotting disorders.
  • Avoid smoking: especially in women over 35 years of age.
  • Monitor blood pressure: check regularly during therapy.
  • Consider liver function: contraindicated in active liver disease.
  • Review medication interactions: especially enzyme‑inducing drugs.
  • Store at ambient temperature: keep below 25 °C, in the original pack, and protect from moisture.

Avoid Interactions

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

Major Interactions (Avoid)

  • Antiepileptic enzyme inducers (e.g., carbamazepine, phenytoin): reduce contraceptive efficacy.
  • Rifampin and rifabutin: decrease hormone levels, compromising protection.
  • Griseofulvin: lowers effectiveness of the hormonal components.

Moderate Interactions (Monitor Closely)

  • Certain antibiotics (e.g., tetracycline, metronidazole): may slightly reduce efficacy.
  • Antifungal azoles (e.g., ketoconazole): can increase hormone concentrations, raising side‑effect risk.
  • Herbal supplements such as St. John’s wort: may reduce contraceptive effectiveness.

Frequently Asked Questions

Kliogest is an oral combined hormonal contraceptive containing norethisterone acetate and estradiol. It is prescribed to prevent pregnancy by inhibiting ovulation and providing cycle control, and it may also be used to regulate menstrual bleeding and treat acne related to androgen excess.

Norethisterone acetate acts as a progestogen, suppressing the mid‑cycle surge of luteinising hormone (LH) and follicle‑stimulating hormone (FSH), which blocks ovulation. Estradiol, an estrogen, stabilises the endometrial lining and contributes to negative feedback on the hypothalamic‑pituitary axis, enhancing cycle regularity.

The specific dosing regimen for Kliogest is determined by the prescribing healthcare professional based on individual patient factors. Patients should follow the prescriber’s instructions and not alter the dose without medical advice.

Kliogest is intended for use as a contraceptive and is not recommended for women who are pregnant or planning to become pregnant. It is generally contraindicated during breastfeeding unless the prescriber determines that the benefits outweigh the risks. Consultation with a healthcare provider is essential.

To order Kliogest, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Kliogest contains the same class of active ingredients—an estrogen (estradiol) and a progestogen (norethisterone acetate)—as many other combined oral contraceptives. Its efficacy and safety profile are comparable, though individual formulations may differ in hormone doses, which can influence side‑effect frequency and specific clinical preferences.

Kliogest tablets should be stored at ambient temperature, below 25 °C, in the original packaging to protect them from moisture and light. Keep the product out of reach of children and do not use if the packaging is damaged.

Kliogest is taken orally, usually once daily at the same time each day, as directed by the prescriber. Consistent daily intake helps maintain hormone levels and maximises contraceptive effectiveness.

The most serious risks include venous thromboembolism, pulmonary embolism, stroke, myocardial infarction, severe hypertension, and rare liver disorders such as hepatic adenoma. Patients should seek immediate medical attention if they experience symptoms such as unexplained leg pain, chest pain, severe headache, or visual changes.

Kliogest is contraindicated in women with a history of thromboembolic disorders, active liver disease, known or suspected breast cancer, uncontrolled hypertension, or those who are pregnant or breastfeeding. It should also be avoided by smokers over 35 years of age and by individuals taking certain interacting medications without medical supervision.
