Prolactin Disease (Hyperprolactinemia & Prolactinoma) Treatment in India

🧬 Prolactin Disease — Hyperprolactinemia & Prolactinoma Treatment in India

Pituitary Endocrinology · Dopamine Agonists · Neurosurgery · Fertility Restoration

💡 Did you know? Prolactinomas are the most common hormone-secreting pituitary tumour, accounting for about 40% of all pituitary adenomas. They are 3–5 times more common in women than men.

🔴 Pathological Causes

• Prolactinoma — the most common pathological cause
• Other pituitary tumours — causing stalk compression and dopamine deficiency
• Hypothyroidism — high TRH levels stimulate prolactin secretion
• Chronic kidney disease or liver disease — reduced prolactin clearance
• Polycystic ovary syndrome (PCOS)
• Empty sella syndrome or pituitary stalk damage

🧠 Symptoms from Tumour Pressure (Large Macroprolactinomas)

• 🤕 Persistent headaches — especially behind the eyes
• 👁️ Visual disturbances — loss of peripheral vision (bitemporal hemianopia) from optic chiasm compression
• 😴 Fatigue & cold intolerance — from secondary hypothyroidism
• 💧 Diabetes insipidus — rare, from posterior pituitary involvement
• 🫧 CSF rhinorrhoea — rare, with very large tumours invading the skull base

1 💊 Dopamine Agonists (First-Line Treatment)

Dopamine agonists are the cornerstone of treatment. They normalise prolactin levels and shrink the tumour by more than 50% in 80–90% of patients.

• Cabergoline (Dostinex) — preferred first-line agent. Given just once or twice a week, typical dose 0.5–2 mg/week. Better tolerated and more effective than bromocriptine.
• Bromocriptine — older alternative, taken daily. Preferred in women planning pregnancy due to longer safety record.
• Quinagolide — non-ergot alternative for patients intolerant of cabergoline.

2 🔪 Trans-Sphenoidal Surgery

Minimally invasive endoscopic trans-sphenoidal surgery (through the nose) is reserved for:

• Patients who cannot tolerate dopamine agonists
• Resistant prolactinomas (failure of medical therapy)
• Acute visual deterioration not responding to medication
• Cystic prolactinomas
• CSF rhinorrhoea
• Pituitary apoplexy (sudden bleeding into tumour)

Indian neurosurgical centres routinely achieve cure rates of 70–90% for microprolactinomas and 30–50% for macroprolactinomas with experienced pituitary surgeons.

3 ☢️ Radiation Therapy

Reserved for aggressive, residual, or recurrent tumours not responding to medication or surgery. Stereotactic radiosurgery (Gamma Knife or CyberKnife) provides precise, single-session radiation with minimal damage to surrounding tissue. Conventional fractionated radiation may be used for very large or invasive tumours.

4 🤰 Fertility Restoration & Pregnancy Management

One of the great successes of treatment: fertility returns in over 90% of women within months of starting dopamine agonists. For those planning pregnancy, bromocriptine is usually preferred due to its longer safety record. Cabergoline can also be used. Most women can stop medication once pregnancy is confirmed, with monitoring throughout pregnancy.

5 🛡️ Long-Term Monitoring & Withdrawal

Patients on dopamine agonists need periodic prolactin levels, MRI scans (1–2 yearly) and visual field tests. After 2 or more years of normal prolactin and tumour shrinkage, careful withdrawal of medication may be attempted in selected patients — about 30–40% remain in long-term remission off treatment.

Q1. Is prolactinoma cancer?

No. Prolactinomas are benign (non-cancerous) tumours of the pituitary gland. They do not spread elsewhere in the body. Malignant prolactinomas are extremely rare.

Q2. Can I get pregnant if I have a prolactinoma?

Yes — fertility returns in over 90% of women once prolactin is normalised with cabergoline or bromocriptine. Most women have successful pregnancies. Your endocrinologist will guide medication adjustment before and during pregnancy.

Q3. Will I need surgery for a prolactinoma?

Most patients (80–90%) do NOT need surgery. Dopamine agonists alone are usually sufficient. Surgery is reserved for resistant tumours, intolerance to medication, or visual emergencies.

Q4. How long do I need to take medication?

Typically at least 2 years of normal prolactin levels and significant tumour shrinkage before considering withdrawal. About 30–40% of patients remain in long-term remission after stopping medication. Some need lifelong therapy.

Q5. What documents do I need to share for a medical opinion?

Please send: (1) serum prolactin levels (multiple readings if available), (2) pituitary MRI report and images, (3) other pituitary hormone tests (TSH, T4, cortisol, LH, FSH, testosterone/estradiol), (4) visual field test, (5) current medication list.
