Indications & Clinical Uses

Neofollin (estradiol valerate) is used in estrogen‑dependent conditions to restore hormonal balance.

  • Menopausal hormone therapy: alleviates vasomotor symptoms and helps maintain bone density in post‑menopausal women.
  • Hypoestrogenism: restores physiologic estrogen levels in women with deficient endogenous production.
  • Primary ovarian insufficiency: provides estrogen replacement to support secondary sexual characteristics and bone health.

How It Works

  • Estradiol valerate is hydrolyzed in vivo to estradiol, which binds to estrogen receptors ERα and ERβ in target tissues. Receptor activation modulates transcription of estrogen‑responsive genes, leading to restoration of estrogenic activity in the hypothalamic‑pituitary‑gonadal axis, bone, cardiovascular and urogenital systems.

Side Effects

Neofollin may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects

  • Nausea or vomiting
  • Breast tenderness or enlargement
  • Headache or dizziness
  • Local injection site pain or erythema
  • Fluid retention or mild edema

Serious or Rare Side Effects

  • Deep vein thrombosis or pulmonary embolism
  • Stroke or myocardial infarction
  • Endometrial hyperplasia or carcinoma
  • Hepatic dysfunction or cholestasis

Precautions & Warnings

Before initiating therapy, clinicians should evaluate individual risk factors and monitor patients regularly.

  • Cardiovascular risk assessment: review history of thromboembolic disease.
  • Liver function monitoring: estradiol can affect hepatic metabolism.
  • Contraindication in estrogen‑dependent tumors: avoid use in known breast or endometrial cancer.
  • Bone health evaluation: consider baseline density and follow‑up.
  • Pregnancy and lactation: use only if clearly indicated after risk‑benefit analysis.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Estradiol valerate can interact with several drug classes; awareness of interaction severity guides clinical decisions.

Major Interactions (Avoid)

  • Anticoagulants (e.g., warfarin): increased risk of thrombotic events.
  • Selective estrogen receptor modulators (e.g., tamoxifen): antagonistic effects.
  • Aromatase inhibitors: counteract estrogenic activity.

Moderate Interactions (Monitor Closely)

  • CYP3A4 inhibitors (e.g., ketoconazole): may raise estradiol levels.
  • CYP3A4 inducers (e.g., rifampin): may reduce efficacy.
  • Thyroid hormone replacement: may require dose adjustment of levothyroxine.

Frequently Asked Questions

Neofollin is an injectable form of estradiol valerate prescribed for hormone replacement therapy. It is indicated to relieve menopausal symptoms, treat hypoestrogenism, and provide estrogen support in women with primary ovarian insufficiency.

After intramuscular injection, estradiol valerate is converted to estradiol, the natural estrogen. The hormone binds to estrogen receptors in various tissues, activating gene transcription that restores estrogen‑dependent physiological functions such as bone maintenance, vasomotor regulation, and urogenital health.

The dosage of Neofollin is individualized. A qualified prescriber determines the amount, frequency, and duration based on the patient’s clinical condition, age, and response to therapy. No fixed regimen is provided in public literature.

Neofollin is generally reserved for women who are not pregnant. Use during pregnancy or lactation is only considered when the potential benefit outweighs the risk, and it should be decided by a healthcare professional after careful evaluation.

To request Neofollin, 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 (including cold‑chain where required) and import documentation.

Neofollin delivers estradiol valerate as a depot injection, offering a longer duration of action compared with oral estradiol tablets that require daily dosing. This can improve adherence but requires intramuscular administration by a trained professional, whereas oral forms are self‑administered.

Neofollin should be stored refrigerated between 2 °C and 8 °C. Protect the vials from light, do not freeze, and avoid shaking. Keep the product in its original packaging until use to maintain stability.

Neofollin is given as an intramuscular injection, typically into the gluteal or deltoid muscle. Administration should be performed by a qualified healthcare professional using aseptic technique, following the dose prescribed by the treating physician.

Serious risks include thromboembolic events such as deep‑vein thrombosis, pulmonary embolism, stroke, and myocardial infarction. Additionally, there is a potential for endometrial hyperplasia or carcinoma, especially in women with pre‑existing estrogen‑dependent conditions.

Neofollin is contraindicated in women with known estrogen‑dependent tumors (e.g., breast or endometrial cancer), active or history of thromboembolic disease, uncontrolled hypertension, liver disease, or those who are pregnant unless clearly indicated by a physician.
