Generic Dostinex Information

Introduction

Dostinex (cabergoline) is a dopamine‑receptor agonist prescribed primarily for the management of hyperprolactinaemia and for adjuvant therapy of Parkinson’s disease. In the United Kingdom it is classified under Women’s Health and Hormones because elevated prolactin levels most commonly affect menstrual function and fertility. The drug is marketed by several manufacturers, the most widely known brand being Dostinex™. Cabergoline’s long‑acting profile allows once‑weekly dosing, offering a convenient alternative to older treatments.

What is Dostinex?

Dostinex is the commercial name for the synthetic ergot derivative cabergoline. It belongs to the class of dopamine‑2 (D₂) receptor agonists. The medication was developed in the 199s by Janssen‑Cilag and received European Union marketing authorisation in 1995 for hyperprolactinaemia. In the UK the Medicines and Healthcare products Regulatory Agency (MHRA) lists Dostinex as a prescription‑only medicine (POM).

Dostinex is the generic version of the original brand name Cabaser®, containing the same active compound cabergoline. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Dostinex Works

Cabergoline mimics the action of dopamine on D₂ receptors located in the anterior pituitary gland. By stimulating these receptors, it suppresses the secretion of prolactin from lactotroph cells. Reduced prolactin levels restore normal gonadotropin release, allowing ovulation, regular menstrual cycles and normal lactation control.

In Parkinson’s disease, dopaminergic deficiency in the basal ganglia contributes to motor symptoms. Cabergoline’s D₂ agonism compensates for this deficit, improving rigidity and tremor. The drug has a high affinity for D₂ receptors and a long elimination half‑life (≈65 hours), which underpins its weekly dosing schedule. Steady‑state plasma concentrations are usually achieved after 2–3 weeks of therapy.

Conditions Treated with Dostinex

• Hyperprolactinaemia – Excess prolactin (> 25 µg/L in women, > 20 µg/L in men) can cause galactorrhoea, amenorrhoea, infertility and sexual dysfunction. Cabergoline normalises prolactin in > 90 % of patients, according to UK‑based observational studies.
• Pituitary Adenomas (Prolactin‑secreting) – Small or macroprolactinomas respond to cabergoline with tumour shrinkage in up to 80 % of cases, reducing the need for surgery.
• Adjunctive Therapy in Parkinson’s Disease – Used when levodopa alone does not control motor fluctuations, cabergoline improves “off” periods and may allow lower levodopa doses.
• Off‑Label Use for Irregular Menstrual Cycles – Some endocrinologists prescribe low‑dose cabergoline to correct menstrual irregularities linked to mildly elevated prolactin.

In the UK, hyperprolactinaemia is estimated to affect .1 % of the adult population, making Dostinex a frequently requested medication in endocrine clinics.

Who is Dostinex For?

• Adults with confirmed hyperprolactinaemia (laboratory‑verified prolactin elevation) who experience symptoms such as infertility, galactorrhoea or menstrual disturbance.
• Patients diagnosed with prolactin‑secreting pituitary adenomas where surgery is contraindicated, or as postoperative adjuvant therapy.
• Individuals with Parkinson’s disease whose motor symptoms are inadequately managed by levodopa alone and who have no contraindication to dopamine agonists.
• Women of child‑bearing age seeking to restore fertility without surgical intervention, provided hepatic and cardiac function are normal.

Contraindications include uncontrolled hypertension, severe cardiac valvulopathy, a history of fibrotic disorders (e.g., retroperitoneal fibrosis), and pregnancy. Cabergoline must be used cautiously in patients with hepatic impairment or psychiatric disorders (e.g., psychosis), as dopamine modulation can exacerbate symptoms.

Risks, Side Effects, and Interactions

Common

• Nausea or vomiting
• Headache
• Dizziness, especially on standing (orthostatic hypotension)
• Fatigue or somnolence
• Nasal congestion

These events are usually mild and transient, often diminishing after the first few weeks of therapy.

Rare

• Valvular heart disease – Dopamine agonists have been linked to valve thickening; routine echocardiography is recommended after ≥ 2 years of high‑dose therapy.
• Pulmonary fibrosis – Extremely uncommon but reported in long‑term ergot use.
• Psychiatric disturbances – Hallucinations or impulse‑control disorders (e.g., pathological gambling) may appear in susceptible individuals.

Serious

• Severe hypotension leading to syncope or falls
• Myocardial infarction or stroke in patients with existing cardiovascular disease
• Allergic anaphylaxis – characterised by rash, swelling, or respiratory compromise; requires immediate medical attention

Drug–Drug Interactions

• Antihypertensives (e.g., ACE inhibitors, diuretics) – additive blood‑pressure‑lowering effect.
• Antipsychotics (e.g., haloperidol, risperidone) – dopamine antagonism may reduce cabergoline efficacy.
• Macrolide antibiotics (e.g., erythromycin) and azole antifungals (e.g., ketoconazole) – CYP3A4 inhibition can increase cabergoline plasma levels, raising toxicity risk.
• Concomitant ergot derivatives – additive risk of fibrotic complications.

Patients should inform their healthcare provider of all prescription, over‑the‑counter and herbal products they are taking.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dose for hyperprolactinaemia: .25 mg orally once weekly. The dose may be titrated up to 1 mg/week based on prolactin response and tolerability.
• Parkinson’s disease adjunct: .5 mg to 2 mg daily in divided doses, as directed by a neurologist.
• Missed dose: If a weekly dose is forgotten, take it as soon as remembered unless the scheduled next dose is within 48 hours; in that case skip the missed dose to avoid double dosing.
• Overdose: Symptoms may include severe nausea, vomiting, hypotension, and altered consciousness. Seek emergency medical care immediately. Activated charcoal may be administered if presentation is within one hour of ingestion.

Precautions

• Take the tablet with water, preferably after a light meal to reduce gastrointestinal upset.
• Avoid alcohol, as it can potentiate dizziness and hypotension.
• Regular monitoring of blood pressure, liver function tests, and, after prolonged therapy, echocardiography is advisable.
• Women planning pregnancy should discontinue cabergoline after consultation; the drug is contraindicated during gestation.

FAQ

• **Can Dostinex be stored at temperatures below room temperature?**
  Cabergoline tablets are stable at 15‑30 °C (59‑86 °F). Refrigeration is not required and may cause condensation that harms the tablet coating.

• **What does the imprint on a Dostinex tablet look like?**
  The typical .5 mg tablet bears the imprint “DOST .5” on one side and a smooth, white surface on the reverse. In the generic version supplied by our pharmacy, the imprint may read “CAB .5”.

• **Is there a difference between UK‑sourced and EU‑sourced Cabergoline?**
  The active ingredient must meet the same European Pharmacopoeia standards regardless of the country of manufacture. Formulation excipients may vary slightly, but efficacy and safety remain equivalent.

• **Do travel restrictions apply when carrying Dostinex across EU borders?**
  When travelling, keep the medication in its original labelled packaging, carry a copy of the prescription, and declare it at customs if requested. The UK’s Personal Importation Scheme permits up to a three‑month supply for personal use.

• **Can cabergoline affect drug‑testing results for athletes?**
  Cabergoline is not listed on the World Anti‑Doping Agency (WADA) prohibited list. However, athletes should disclose any medication to their governing body, as some labs may flag dopamine‑modulating agents for further review.

• **What is the history behind the development of cabergoline?**
  Cabergoline was first synthesised in the 198s by a team at Janssen Pharmaceutica, aiming to create a long‑acting dopamine agonist with fewer side effects than earlier ergot derivatives. It received its first regulatory approval for hyperprolactinaemia in 1995.

• **How does cabergoline compare with bromocriptine for prolactin suppression?**
  Clinical trials have shown cabergoline to be more effective in normalising prolactin at lower weekly doses and to have a better tolerability profile. Bromocriptine requires daily dosing and is associated with higher rates of nausea.

• **Is there any evidence that cabergoline improves mood in patients with depression?**
  Small pilot studies suggest dopaminergic stimulation may have modest antidepressant effects, but cabergoline is not licensed for depression and larger trials are lacking. Patients should not self‑medicate for mood disorders.

• **Can Dostinex be crushed or split for dose adjustment?**
  The tablet is scored for easy division; splitting is acceptable for dose titration. Crushing is discouraged because it may affect the drug’s release profile and increase gastrointestinal irritation.

• **What are the legal limits for importing Dostinex for personal use into the UK?**
  Under the MHRA’s personal importation rules, a non‑prescription consumer may receive up to a three‑month supply, provided a valid prescription is presented and the product is from a licensed source. Larger quantities require a special import licence.
