Parlodel (Bromocriptine) – Patient Information (UK)
Parlodel is a brand of bromocriptine, a medicine used to treat several hormone-related conditions. It works by affecting brain chemicals that control prolactin (a hormone involved in milk production), and it can also help with certain movement disorders. This guide explains how Parlodel works, how it’s used, common practical considerations, and key safety information to help you feel confident using your medicine.
Important: This page is for general information. Always follow the advice of your healthcare professional and the instructions provided with your medicine. If you have questions about your specific situation, ask a pharmacist or doctor.

What Parlodel is used for (typical indications)
Parlodel is used in the UK for a range of conditions linked to high prolactin levels and other dopamine-related effects. The exact indication determines the dose and schedule.
Common indications include
- Hyperprolactinaemia: Conditions where the body produces too much prolactin, leading to symptoms such as irregular periods, fertility problems, or milk production not related to childbirth.
- Prolactin-secreting pituitary adenomas (prolactinomas): Benign pituitary tumours that increase prolactin.
- Galactorrhoea: Breast milk production not due to pregnancy or breastfeeding, often linked to elevated prolactin.
- Parkinson’s disease and parkinsonism: To improve movement symptoms by replacing or mimicking dopamine activity.
- Off-label or specialist-use situations: In some circumstances, specialists may use bromocriptine for other dopamine-responsive conditions. Your clinician will advise if this applies to you.
Note: Parlodel may also be used in specific reproductive-related settings under specialist supervision. The safest approach is to follow your healthcare professional’s plan exactly.
How Parlodel works (mechanism of action)
Bromocriptine is a dopamine receptor agonist. Dopamine is a natural chemical messenger in the brain. In normal physiology, dopamine helps control prolactin release from the pituitary gland.
- Prolactin reduction: Bromocriptine stimulates dopamine receptors (mainly D2 receptors) on lactotroph cells in the pituitary, which reduces prolactin secretion.
- Movement effects: In Parkinson’s disease, dopamine activity in specific brain pathways is reduced. By acting like dopamine at receptors, bromocriptine may help improve motor symptoms.
Because prolactin levels are affected, many hormone-related symptoms improve as levels normalise.
Pharmacokinetics: what the body does to Parlodel
Pharmacokinetics describes how the medicine is absorbed, distributed, metabolised, and removed from the body.
- Absorption: Bromocriptine is taken by mouth and is absorbed from the gastrointestinal tract. Absorption can be influenced by food, timing, and individual factors.
- Distribution: It distributes into tissues and can cross into the central nervous system, which is relevant to its effects on movement and brain hormones.
- Metabolism: Bromocriptine is primarily metabolised by the liver (commonly via cytochrome P450 enzymes). This means other medicines that affect liver enzymes may change levels of bromocriptine.
- Elimination: Metabolites are excreted mainly via the faeces and urine.
Half-life: Reported half-life can vary, and the clinical effect may outlast a single dosing interval. Your prescriber sets the dose based on your condition and response.
How to take Parlodel: timing and practical use
Parlodel dosing depends on the condition being treated. Always use the schedule provided by your healthcare professional. Below are general practical tips that many people find helpful.
General timing guidance
- Take it with food if needed: If you experience nausea or stomach upset, taking bromocriptine with food may improve tolerability (your clinician can advise the best approach for you).
- Consistency matters: Try to take each dose at roughly the same times daily.
- Do not double up: If you miss a dose, follow the advice in your medicine information leaflet (or ask your pharmacist). In general, doubling can increase side effects.
- Do not stop suddenly unless advised: For long-term therapy, sudden stopping can be problematic. Discuss any changes with a clinician.
Starting and dose adjustments
Many patients start on a lower dose and increase gradually to reduce side effects such as dizziness or nausea. Follow the titration plan carefully.
Food interactions: can you take Parlodel with meals?
Food may affect how bromocriptine is absorbed. For some people, taking Parlodel with food reduces gastrointestinal side effects.
- General approach: If your leaflet or clinician advises, take it with meals.
- Be consistent: If you start taking it with food, continue similarly to avoid day-to-day fluctuations.
- Absorption differences: Some medicines and meals can change drug absorption patterns. If you notice changes in symptoms after altering meal timing, speak to your pharmacist.
Alcohol interactions and alcohol safety
Alcohol can increase the risk of side effects such as drowsiness, dizziness, and low blood pressure. Bromocriptine may already cause these effects in some people.
Practical advice
- Limit or avoid alcohol until you know how Parlodel affects you.
- Be cautious with activities requiring alertness (driving, operating machinery) if you feel dizzy or sleepy.
- Report concerning effects (fainting, severe dizziness, unusual sleepiness) to a healthcare professional promptly.
Medicine interactions: important drug-to-drug considerations
Bromocriptine can interact with other medicines, particularly those affecting dopamine pathways, blood pressure, or liver metabolism. Always tell your pharmacist about:
- All prescription medicines
- Over-the-counter products
- Herbal supplements
- Any recent changes to medicines
Common categories that may interact
- Antipsychotics (dopamine antagonists) may reduce the effect of bromocriptine.
- Other dopamine-related medicines may alter effects or side-effect risk.
- Blood pressure medicines: bromocriptine can lower blood pressure in some people; combining may increase dizziness or faintness.
- Medicines that affect liver enzymes (for example certain antibiotics/antifungals or anti-seizure medicines) may change bromocriptine levels.
- Medicines that cause nausea or those used to treat it may be considered together for tolerability planning.
Signs an interaction may be happening
- Symptoms worsening unexpectedly
- New or stronger dizziness, fainting, or severe sleepiness
- Unusual involuntary movements or severe restlessness
- Severe stomach upset that doesn’t improve
If you suspect an interaction, seek advice from a pharmacist or prescriber rather than stopping abruptly.
Dose and how Parlodel is typically used
Because Parlodel is used for multiple conditions, dosing varies. Below are typical ranges used in clinical practice to help you understand how doctors often approach dosing. Your exact dose may differ.
| Condition (examples) | Typical starting approach | Typical dosing schedule | Adjustments |
|---|---|---|---|
| Hyperprolactinaemia / prolactinoma | Low dose initially to reduce side effects | Often taken 1–2 times daily | Dose may increase based on prolactin blood test results and symptom response |
| Galactorrhoea | Low dose initially | Usually 1–2 times daily | Adjusted depending on symptom improvement and prolactin levels |
| Parkinson’s disease | Low dose with gradual titration | Often 2–3 times daily depending on response | Increased carefully to balance symptom control and side effects |
Follow your local instructions: Your healthcare professional will prescribe the exact strength and schedule. Tablets may come in different strengths; ensure you’re taking the correct number of tablets.
Practical tip for dosing
- Use reminders (phone alarm, pill organiser) to help you take doses on time, especially when multiple daily doses are needed.
- Keep a simple log (what time you took it and any side effects). This helps your clinician fine-tune therapy.
Safety profile: side effects and when to seek help
Like all medicines, Parlodel (bromocriptine) can cause side effects. Many are mild and improve as your body adjusts, but some require urgent medical attention.
Common side effects
- Nausea and indigestion
- Dizziness or feeling light-headed
- Headache
- Fatigue
- Low blood pressure (sometimes especially on standing)
- Stomach upset
Less common but important effects
- Fainting or severe dizziness
- Hallucinations, confusion, or unusual behaviour (more relevant in some people, especially with Parkinson’s therapy)
- Uncontrolled sleepiness or sudden sleep episodes (important for driving safety)
