Parlodel (Bromocriptine) – Patient Information (UK)

Parlodel is a brand of bromocriptine, a medicine used to treat a number of hormone-related conditions. It works by affecting dopamine activity in the body. Parlodel may be used for problems linked to high levels of prolactin, and for some other conditions where dopaminergic treatment is helpful.

This page explains how Parlodel works, how it is typically taken, practical tips, key safety information, and what to discuss with a healthcare professional. Product details may vary depending on the specific formulation and strength available in the UK.

Key product information

How Parlodel works (mechanism of action)

Bromocriptine is a dopamine agonist. Dopamine is a natural chemical messenger that helps regulate several processes, including control of prolactin release from the pituitary gland.

Under normal circumstances, dopamine acts as a “brake” on prolactin production. Parlodel stimulates dopamine receptors in the pituitary, leading to a reduction in prolactin levels. This can help:

• restore normal reproductive hormone balance
• reduce symptoms related to high prolactin
• shrink or control certain prolactin-secreting pituitary tumours (in appropriate cases)

Depending on the indication, bromocriptine may also have effects that influence other hormone systems and neurological pathways.

Pharmacokinetics (what the body does to the medicine)

“Pharmacokinetics” describes how the body absorbs, distributes, metabolises, and eliminates a medicine. For bromocriptine, the general principles are:

• Absorption: Bromocriptine is absorbed after oral use. Food can alter absorption rates and tolerability.
• Distribution: It distributes into body tissues and may reach target areas such as the pituitary.
• Metabolism: Bromocriptine is extensively metabolised by the liver.
• Elimination: Metabolites are eliminated primarily via the liver and bile pathways.
• Onset and steady effects: Effects on prolactin can develop over days, while full clinical benefits may take weeks depending on the condition.

Individual responses can vary. Your prescriber may adjust your dose gradually to improve tolerability.

Typical uses in the UK

Parlodel/bromocriptine is used for a range of conditions, particularly those involving raised prolactin. It may be prescribed in adults for:

• Hyperprolactinaemia (high prolactin levels) causing symptoms such as irregular or absent periods, infertility, or milk production not related to breastfeeding.
• Prolactin-secreting pituitary tumours (prolactinomas) where reduction in prolactin and tumour control is needed.
• Conditions requiring suppression of lactation in certain situations (use depends on clinical context and local guidance).
• Selected Parkinson’s disease-related uses where dopaminergic therapy is appropriate (depending on formulation and treatment plan).

Not every use is suitable for every patient. The best option depends on your symptoms, medical history, and any other medicines you take.

Timing: when to take Parlodel

Bromocriptine dosing is often split across the day to improve tolerability and maintain steady effect. A common practical approach is to take doses at set times, and to keep the schedule consistent.

General timing guidance

• Follow your dosing schedule carefully: take at the times instructed for your condition.
• Try to take the first doses in a safe time window: some people feel dizzy or nauseated early in treatment.
• Do not double up if you miss a dose—ask a pharmacist for advice on what to do for your specific schedule.

If you are starting treatment or increasing the dose, you may be advised to do so gradually to reduce side effects.

Food interactions and taking with meals

Food can influence the absorption and tolerability of bromocriptine. If you feel nausea or dizziness after taking Parlodel, your pharmacist or prescriber may advise adjusting how you take it relative to meals.

Practical advice

• Take with food if you experience stomach upset.
• If recommended for you, follow a consistent approach such as taking with meals or after a meal.
• Avoid abrupt changes in meal timing if it affects how you feel.

While bromocriptine does not have a “one-size-fits-all” food rule, patient experience often improves when the medicine is taken with a small meal.

Alcohol and medicine interactions

Combining Parlodel with alcohol may worsen side effects such as dizziness, sleepiness, or low blood pressure. For safety, it’s generally best to limit alcohol and avoid binge drinking.

Medicine interactions to be aware of

Bromocriptine can interact with other medicines, sometimes by changing levels in the body or by increasing side effects. Tell a healthcare professional about all medicines you use, including over-the-counter products and supplements.

• Other dopamine-related medicines: may increase risk of side effects.
• Antipsychotics: some medicines in this group can reduce the effect of dopamine agonists.
• Blood pressure medicines: there may be an increased risk of low blood pressure (especially when starting or increasing dose).
• Medicines that affect liver enzymes (certain anti-infectives, antifungals, and some other drug classes): may alter bromocriptine metabolism.
• Some migraine medicines and other prescription therapies: interaction potential varies—ask a pharmacist if unsure.

If you have a long-term condition and take multiple medicines, it can help to bring a list to your pharmacist so they can check interactions.

Indications (when Parlodel may be considered)

Below are common indications where bromocriptine is used. Availability and exact labelling may differ by product and patient circumstances.

• Hyperprolactinaemia: to lower prolactin and relieve symptoms.
• Prolactinomas: to reduce prolactin secretion and help control tumour size.
• Suppression of lactation: in certain post-partum or clinical scenarios.
• Parkinson’s disease: as part of dopaminergic treatment strategies.

If you are using Parlodel for prolactin-related symptoms, follow-up blood tests may be used to monitor response.

Dosing: what patients should know

Dosing depends on the condition being treated, your age, how you respond, and how well you tolerate the medicine. Doctors commonly begin with a lower dose and increase gradually.

How dosing is often structured

• Start low: to reduce dizziness, nausea, and blood pressure changes.
• Increase gradually: based on clinical response and side effects.
• Split doses: to maintain tolerability and steady effects.

Examples of dosing principles (not a personal prescription)

Many treatment plans follow a “titration” approach (slow dose adjustment). For exact dose and schedule for you, refer to the instructions provided with your medicine.

• Prolactin-related treatment: frequently involves divided dosing across the day with gradual increases.
• Parkinson’s disease treatment: titration is tailored to symptom control and tolerability.

If you’re unsure about how to take your tablets, speak to a pharmacist. Never change dose schedules without advice.

Safety profile: side effects and when to get help

Like all medicines, Parlodel can cause side effects. Many are more likely when starting treatment or after dose increases. Some side effects can be managed by dose adjustments or taking the medicine with food.

Common side effects

• Nausea, indigestion, or stomach upset
• Dizziness (including light-headedness)
• Headache
• Fatigue or sleepiness
• Low blood pressure symptoms (e.g., feeling faint when standing)
• Constipation or changes in appetite

Less common but important risks

• Falls or fainting: particularly during the first days of treatment or after dose increases.
• Sudden sleepiness: in some people, dopaminergic medicines can cause excessive sleepiness.
• Unusual behaviours or impulse control issues: rare, but important to recognise early (e.g., gambling urges, increased libido, compulsive spending).
• Hallucinations or confusion: especially in older patients or those with other risk factors.
• Heart valve or cardiovascular concerns: monitoring may be considered in longer-term therapy depending on individual risk.
• Severe allergic reaction: seek urgent help if you develop swelling, rash, or breathing difficulties.

When to seek urgent medical advice

Seek urgent medical care or emergency help if you experience:

• chest pain, severe shortness of breath, or symptoms of stroke
• fainting that does not quickly resolve
• severe persistent vomiting or dehydration
• severe headache with visual symptoms or neurological changes
• signs of an allergic reaction (swelling of face/lips, wheezing, widespread rash)

If you experience severe side effects, stop and seek urgent advice as appropriate. Do not ignore symptoms that feel rapidly worsening.

Practical use tips (to help you stay comfortable)

Getting started

• Be cautious when standing: move slowly from sitting or lying positions, especially at the start.
• Take with food if nausea happens: this can improve tolerability for many people.
• Keep a symptom diary: track side effects and time of dosing to help your pharmacist adjust the plan.

Adherence and routine

• Use reminders if dosing is frequent—missed doses can affect symptom control.
• Avoid sudden changes unless advised, especially if you are stable.

Driving and operating machinery

Bromocriptine can cause dizziness or sleepiness. Until you know how it affects you, use caution with driving or operating machinery. If you become unusually drowsy or fall asleep unexpectedly, seek medical advice promptly and avoid driving.

Stopping or missing doses

Do not stop Parlodel suddenly unless you’re instructed to do so by a healthcare professional. Stopping can lead to return of symptoms or other effects depending on the indication.

Missed dose guidance

If you miss a dose, it may be appropriate to take it when you remember unless it is close to the next dose. Because schedules vary, ask a pharmacist for advice for your specific timing.

Alternative options

If Parlodel is not suitable due to side effects, interactions, or specific clinical needs, your healthcare professional may consider alternatives. The best choice depends on the reason you are taking bromocriptine.

Common alternatives (depending on indication)

• Other dopamine agonists used for prolactin-related conditions (examples depend on local prescribing practice).
• Prolactin monitoring and symptom management approaches if medication is not tolerated.
• Surgical or radiotherapy options in selected pituitary tumour cases (specialist-led).
• For Parkinson’s disease, other dopaminergic medicines or combination regimens may be considered.

Only switch medicines under medical guidance. Different dopamine agonists can vary in side effect profiles and dosing schedules.
