Generic Dostinex Information

Introduction

Dostinex (cabergoline) is an oral dopamine‑agonist used primarily to treat hyperprolactinaemia – a condition in which excess prolactin disrupts menstrual cycles, fertility and lactation. In Hong Kong, Dostinex is prescribed by endocrinologists, obstetric‑gynaecologists and neurologists for its ability to normalise prolactin levels with once‑weekly dosing. The medication belongs to the Women’s Health and Hormones groups and is manufactured by several international pharmaceutical companies under strict regulatory oversight. In addition to prolactin‑related disorders, Dostinex is approved for the management of Parkinson’s disease and certain pituitary tumours, providing clinicians with a versatile therapeutic option.

What is Dostinex?

• Definition – Dostinex is a brand name for the synthetic ergot derivative cabergoline. It is classified as a long‑acting dopamine‑2 (D2) receptor agonist.
• Development – Cabergoline was first synthesized in the 198s and received European Union approval in 1997 for hyperprolactinaemia. Subsequent approvals followed in the United States (1999) and other jurisdictions, including Hong Kong.
• Manufacturer – The original product is marketed by Ipsen (formerly by Abbott Laboratories) and distributed in Hong Kong through licensed local wholesalers.
• Generic availability – Numerous reputable generic manufacturers produce cabergoline tablets that contain the same active ingredient, dosage strength and bioavailability as the brand‑name product.

How Dostinex Works

Cabergoline binds selectively to dopamine‑2 receptors located on lactotroph cells in the anterior pituitary gland. Activation of these receptors inhibits the secretion of prolactin, thereby reducing circulating prolactin concentrations.

• Onset – Serum prolactin levels typically decline within 24‑48 hours after the first dose.
• Duration – Cabergoline has a long plasma half‑life of approximately 65 hours, allowing sustained receptor activation with once‑weekly dosing.
• Clearance – The drug is metabolised primarily by hepatic cytochrome P450 enzymes (CYP2D6, CYP3A4) and excreted in the urine and feces. Impaired liver function can modestly extend the elimination period.

The same dopaminergic mechanism also provides modest stimulation of striatal dopamine pathways, which accounts for its utility in Parkinson’s disease at higher doses.

Conditions Treated with Dostinex

• Hyperprolactinaemia (primary indication) – Normalises prolactin, restores ovulation, alleviates galactorrhoea and improves fertility.
• Pituitary adenomas – Small prolactin‑secreting tumours (micro‑adenomas) often shrink with cabergoline therapy, reducing the need for neurosurgery.
• Parkinson’s disease (adjunct therapy) – Improves motor symptoms when added to levodopa at doses up to 3 mg per day.
• Restless‑leg syndrome (off‑label) – Dopaminergic activity can lessen sensory disturbances in some patients.

In Hong Kong, hyperprolactinaemia is estimated to affect .2–.4 % of women of reproductive age, making Dostinex a frequently prescribed endocrine medication. Early treatment can prevent long‑term infertility and bone‑density loss associated with chronic estrogen deficiency.

Patient Groups Most Likely to Benefit

• Women with menstrual irregularities caused by elevated prolactin (e.g., oligomenorrhoea, amenorrhoea).
• Couples facing infertility where a female partner’s prolactin level exceeds the normal range (> 25 ng/mL).
• Patients with prolactin‑secreting micro‑adenomas that are < 10 mm in diameter and not causing visual field defects.
• Parkinson’s patients who require additional dopaminergic stimulation but cannot tolerate higher levodopa doses.

Contra‑indications / caution – Individuals with uncontrolled hypertension, severe hepatic impairment, or a history of fibrotic disorders (e.g., pulmonary, cardiac or retroperitoneal fibrosis) should avoid Dostinex or use it under strict supervision. Pregnant or breastfeeding women must discuss risks with their physician, as safety data are limited.

Risks, Side Effects, and Interactions

Common

• Nausea or vomiting
• Headache
• Dizziness or light‑headedness (orthostatic hypotension)
• Fatigue
• Nasal congestion

Rare

• Valvular heart disease (particularly mitral regurgitation) – screening echocardiography recommended for long‑term use.
• Pulmonary or retroperitoneal fibrosis – reported in isolated case series.
• Psychotic symptoms (hallucinations, worsening of underlying schizophrenia).

Serious

• Severe hypotension leading to syncope.
• Cardiac arrhythmias (especially in patients with pre‑existing conduction disorders).
• Life‑threatening allergic reactions (anaphylaxis).

Drug–Drug Interactions

• CYP2D6 inhibitors (e.g., fluoxetine, paroxetine, quinidine) may increase cabergoline plasma concentrations, raising the risk of side effects.
• Antihypertensives – additive hypotensive effect; monitor blood pressure closely.
• Levodopa – combined therapy may enhance dopaminergic effects; dosage adjustments may be needed.
• Ergot‑derived medications (e.g., ergotamine) – additive risk of vasospasm and fibrosis.

Patients should provide a complete medication list to their prescriber, including over‑the‑counter supplements and herbal products.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dose for hyperprolactinaemia – .5 mg (one tablet) taken orally once weekly. Dose may be titrated to 1 mg weekly after 4 weeks if prolactin remains elevated.
• Parkinson’s disease adjunct – .5 mg to 1 mg taken 2–3 times weekly, not exceeding a total of 3 mg per day.
• Administration – Swallow tablet whole with water; may be taken with or without food, but consistency improves absorption.
• Missed dose – If a dose is forgotten for less than 48 hours, take it as soon as remembered and resume the regular weekly schedule. Do not double‑dose to “catch up.”
• Overdose – Symptoms may include severe nausea, vomiting, profound hypotension and loss of consciousness. Seek emergency medical care immediately; supportive measures (IV fluids, pressors) are standard.

Precautions – Avoid alcohol while initiating therapy, as it can exacerbate dizziness. Patients with renal impairment generally do not require dose adjustment, but those with hepatic disease should start at the lowest dose and monitor liver function tests.
