Indications & Clinical Uses

  • Katya, a combined oral contraceptive, is used in the hormonal regulation of reproduction.
  • Contraception: Provides reliable prevention of pregnancy when taken as prescribed.
  • Regulation of menstrual cycles: Helps achieve more predictable bleeding patterns.
  • Acne management: May improve acne associated with hormonal fluctuations.

How It Works

  • Ethinylestradiol/Gestodene works by suppressing the hypothalamic‑pituitary‑ovarian axis, inhibiting the mid‑cycle surge of luteinising hormone (LH) and follicle‑stimulating hormone (FSH). This prevents ovulation. The estrogen component stabilises the endometrial lining, while the progestogen thickens cervical mucus and alters the endometrium, creating conditions unfavorable for implantation.

Side Effects

Katya may cause a range of adverse reactions. Most are mild and transient.

Common Side Effects

  • Nausea or mild gastrointestinal upset
  • Breast tenderness or enlargement
  • Headache or migraine
  • Spotting or breakthrough bleeding
  • Weight gain or fluid retention
  • Mood changes or irritability

Serious or Rare Side Effects

  • Venous thromboembolism (deep‑vein thrombosis, pulmonary embolism)
  • Arterial thrombosis (stroke, myocardial infarction)
  • Severe hypertension
  • Liver dysfunction or cholestatic jaundice
  • Allergic reactions (rash, angioedema, anaphylaxis)
  • Visual disturbances or eye pain

Precautions & Warnings

  • Before prescribing Katya, clinicians should evaluate individual risk factors and counsel patients on safe use.
  • Cardiovascular assessment: Review history of thrombosis, hypertension, or smoking.
  • Liver function: Avoid in active liver disease or severe hepatic impairment.
  • Smoking restriction: Advise women >35 years who smoke to discontinue use.
  • Missed dose management: Provide clear instructions for handling forgotten tablets.
  • Drug‑interaction review: Check concomitant medications that may reduce efficacy.
  • Store at ambient temperature: Keep below 25 °C in the original packaging, protected from moisture.

Avoid Interactions

Katya can interact with several medicines, altering its contraceptive effectiveness or increasing adverse effects.

Major Interactions (Avoid)

  • Strong CYP3A4 inducers (e.g., phenytoin, carbamazepine, rifampin, St. John's wort) – may markedly reduce hormone levels.
  • Certain antiretrovirals (e.g., efavirenz) – can diminish contraceptive efficacy.
  • High‑dose glucocorticoids – may increase risk of thrombotic events.

Moderate Interactions (Monitor Closely)

  • Antifungal agents (ketoconazole, itraconazole) – may increase hormone concentrations.
  • Macrolide antibiotics (erythromycin, clarithromycin) – modestly raise plasma levels.
  • Selective serotonin reuptake inhibitors – may exacerbate mood‑related side effects.

Frequently Asked Questions

Katya is a combined oral contraceptive containing ethinylestradiol and gestodene. It is prescribed to prevent pregnancy and to help regulate menstrual cycles in women of reproductive age.

The combination suppresses the release of luteinising hormone and follicle‑stimulating hormone, preventing ovulation. The estrogen stabilises the endometrium, while the progestogen thickens cervical mucus and alters the uterine lining, reducing the chance of implantation.

The dosing regimen for Katya is determined by the prescribing healthcare professional. Typically, it is taken as a daily oral tablet following the specific cycle schedule indicated on the prescription label.

Katya is intended for use only when pregnancy is not desired. It should not be started during pregnancy, and women who become pregnant while using it should discontinue the product. Safety during breastfeeding has not been established; a healthcare provider should be consulted.

To order Katya, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Katya contains gestodene, a third‑generation progestogen, which may be associated with a lower incidence of androgenic side effects such as acne compared with older progestins. Its efficacy in preventing pregnancy is comparable to other combined oral contraceptives when taken correctly.

Katya tablets should be stored at ambient temperature, below 25 °C, in the original blister pack or container. Protect them from excess moisture and direct sunlight to maintain product stability.

Katya is taken orally, usually once daily at the same time each day. The tablets are typically packaged in a 21‑day active pill series followed by a 7‑day placebo or pill‑free interval, during which withdrawal bleeding occurs.

Serious risks include venous or arterial thromboembolism, severe hypertension, liver disorders, and rare allergic reactions such as anaphylaxis. Patients should seek immediate medical attention if they experience symptoms like sudden chest pain, shortness of breath, severe headache, or visual changes.

Katya is contraindicated in women with a history of thromboembolic disorders, uncontrolled hypertension, active liver disease, known or suspected breast cancer, or those who are pregnant. It should also be avoided by smokers over 35 years of age.
