Parlodel (Bromocriptine) – Patient Information (Australia)

Parlodel is a prescription medicine containing bromocriptine, a medicine that affects certain brain receptors involved in the hormone prolactin and related processes. It is used for specific medical conditions and may be recommended by a healthcare professional based on your individual situation.

This page explains how Parlodel works, typical uses, what to expect, important safety information, and practical tips to help you use the medicine more confidently.

Key product information

How Parlodel works (mechanism of action)

Bromocriptine works by acting like dopamine at certain receptors. Dopamine helps regulate the release of prolactin from the pituitary gland. By stimulating dopamine receptors, bromocriptine:

• Decreases prolactin levels in the body
• Helps shrink or reduce the effects of certain prolactin-related conditions (depending on the cause)
• In some conditions, may help relieve symptoms by altering dopamine signalling in the brain

Because it influences dopamine pathways, Parlodel may also affect blood pressure, nausea, and alertness in some people.

Pharmacokinetics (how your body handles bromocriptine)

Pharmacokinetics describes what happens after you swallow a dose: absorption, distribution, metabolism, and elimination. While individual results vary, the general pattern for bromocriptine is:

• Absorption: Bromocriptine is absorbed from the gastrointestinal tract after oral dosing. Taking it with food may reduce some side effects (especially nausea).
• Distribution: It distributes into body tissues and crosses into the brain, which contributes to its effects.
• Metabolism: Bromocriptine is extensively metabolised in the liver. This is one reason drug interactions may occur.
• Elimination: Metabolites are eliminated mainly via the bile and faeces, with a smaller contribution via urine.

If you miss a dose or experience side effects, speak with your healthcare provider before making changes.

Typical uses in clinical practice

Parlodel is used for several conditions. The most common involve prolactin and dopamine-related pathways. Your clinician will determine whether bromocriptine is appropriate for you.

Common indications

• Hyperprolactinaemia (elevated prolactin levels), including when prolactin is increased due to certain pituitary disorders
• Prolactin-secreting pituitary adenomas (prolactinomas), including conditions where reduction of tumour size and/or prolactin levels is desired
• Disorders related to excess prolactin such as certain causes of irregular or absent periods, infertility related to prolactin, and related symptoms (as determined by your doctor)
• Parkinson’s disease and related conditions in selected situations, depending on treatment plan and tolerability
• Acromegaly (raised growth hormone), as part of a specialist-led regimen

Note: Not every patient needs the same therapy or dose, and treatment goals vary (e.g., symptom control vs long-term endocrine control).

When to take Parlodel (timing guidance)

Follow your healthcare professional’s instructions. In general, bromocriptine is taken by mouth, often with food to improve tolerability.

• With meals: Taking it with food may help reduce nausea and stomach upset.
• Consistent timing: Try to take doses at the same times each day to maintain steadier effects.
• Start low, go slow: Many regimens begin with a lower dose and increase gradually to minimise side effects.
• Missed dose: If you miss a dose, take it when you remember unless it is close to the next dose. Do not double up. If unsure, ask your pharmacist or doctor.

If you feel dizzy, light-headed, or overly sleepy, avoid driving and seek medical advice—especially after dose changes.

Food interactions

Food can affect how well you tolerate bromocriptine. While bromocriptine may be absorbed with or without food, eating may make it gentler on the stomach.

Practical advice regarding meals

• Take with food if you experience nausea or stomach discomfort.
• If your clinician has provided specific directions (e.g., “with meals” or “on an empty stomach”), follow those directions precisely.
• Maintain a regular eating pattern to help reduce variability in how you feel after each dose.

There are no specific “forbidden” foods generally listed for bromocriptine, but individual tolerability varies.

Alcohol interactions and other medicines

Alcohol and bromocriptine

Alcohol can worsen side effects of Parlodel in some people—particularly dizziness, drowsiness, and impaired judgement. As a result, it’s generally best to limit or avoid alcohol while starting or adjusting bromocriptine, and speak to your pharmacist if you plan to drink.

Be extra cautious if you:

• Start Parlodel or have a recent dose increase
• Already experience sleepiness or “blackout” episodes
• Take other medicines that affect the brain (see below)

Drug interactions (medicine combinations to discuss)

Bromocriptine is metabolised by liver enzymes and may interact with other medicines. Tell your healthcare professional about all medicines, supplements, and herbal products you use.

Medicines that may require extra caution

• Antipsychotics (dopamine antagonists) may reduce bromocriptine’s effect.
• Metoclopramide and similar dopamine-related medicines may influence outcomes.
• Some antibiotics or antifungals may change bromocriptine levels through liver metabolism pathways.
• HIV medicines and other medicines that affect the liver enzyme system may alter bromocriptine exposure.
• Blood pressure medicines: Parlodel can affect blood pressure. Combination may increase risk of dizziness or fainting.
• Medicines causing drowsiness (for example, some sleep medicines, strong antihistamines, opioids): together they may increase sleepiness or impairment.

If you’re unsure whether a medicine interacts, ask a pharmacist. Keeping an up-to-date list can make this quicker.

Dosing: what to expect

Dosage depends on the condition being treated, your age, medical history, and how you respond to treatment. Many patients begin with a lower dose and have gradual adjustments to reduce side effects.

General principles (not a substitute for your plan)

• Start low: A small starting dose helps your body adapt.
• Increase gradually: Your prescriber may increase dose every few days or weeks, depending on your response.
• Split dosing: Some regimens use divided doses across the day for steadier tolerability.
• Monitor response: For prolactin-related conditions, blood tests may be used to guide dosing.

Important: Use the exact dose and schedule your healthcare professional specifies. Do not stop or change dosage without advice.

Safety profile and side effects

Like all medicines, Parlodel can cause side effects. Not everyone will experience them, and side effects may improve as your body adjusts.

Common side effects

• Nausea or stomach upset
• Dizziness or light-headedness (especially when standing)
• Headache
• Fatigue
• Low blood pressure symptoms (e.g., feeling faint)
• Vomiting (less common but possible)

Less common but serious risks

Seek urgent medical help if you experience symptoms that could indicate a serious reaction.

• Severe chest pain, shortness of breath, or swelling (rare but important)
• Fainting or severe dizziness
• Hallucinations, confusion, or unusual behaviour changes
• Severe or persistent headache or vision changes
• Signs of allergic reaction such as rash, swelling of the face/lips, or difficulty breathing

Impulse control and sleep-related effects

Dopamine agonists can, in some individuals, be associated with behavioural changes such as:

• Compulsive behaviours (e.g., gambling or increased urges)
• Changes in libido
• Sudden sleep onset or significant sleepiness

Tell your doctor promptly if you or your family notice unusual urges, behavioural changes, or sudden sleepiness. Avoid driving or operating machinery if you feel drowsy.

Practical use tips to improve tolerability

• Take with food if nausea is a problem, unless your clinician instructs otherwise.
• Rise slowly from sitting or lying positions to reduce dizziness.
• Hydrate and keep meals regular, especially during dose increases.
• Keep track of side effects (time, severity, dose taken) and share this with your pharmacist/doctor.
• Be cautious with driving, especially when starting or increasing the dose.
• Don’t stop suddenly without professional advice—dose adjustments may be needed gradually.

What if you miss a dose?

If you forget a dose, take it as soon as you remember if it’s not close to the next dose. If it is near the next dose, skip the missed dose and continue your schedule. Do not take double doses to make up for the missed one.

If you miss several doses, contact your healthcare professional for guidance on how to restart safely.

Alternative options

Treatment alternatives depend on the condition being treated (e.g., elevated prolactin, pituitary adenoma, Parkinson’s disease, acromegaly). Below are common categories that may be considered by clinicians.

Possible alternatives (discuss with a healthcare professional)

• Other dopamine agonists for prolactin-related disorders (choice depends on tolerability and availability).
• Non-oral treatments or surgical options for selected pituitary conditions (specialist-led decision).
• Other medicines targeted to the underlying condition, such as hormone-regulating therapies in endocrine disorders.
• Supportive management (e.g., symptom control) alongside disease-specific treatment.

Your clinician can explain which alternative best fits your goals, medical history, and side effect risks.
