Parlodel (Generic Bromocriptine): Complete Medication Guide
Key Takeaways
Bromocriptine is a dopamine agonist that lowers prolactin levels and treats conditions like hyperprolactinemia and Parkinson's disease.
Common side effects include nausea, dizziness, and headaches, while serious side effects may involve heart problems or severe blood pressure changes.
Dosing starts low and increases gradually, typically taken with food to minimize stomach upset.
Drug interactions are possible with certain blood pressure medications, antipsychotics, and other dopamine-related drugs.
Bromocriptine is a cost-effective alternative to brand-name drugs and works the same way as the brand-name Parlodel.
Parlodel (Generic Bromocriptine) Overview
Bromocriptine is a dopamine agonist—a medication that mimics the effects of dopamine, a chemical messenger in the brain. It's used to treat conditions caused by high prolactin levels, including hyperprolactinemia (excess prolactin), prolactinomas (prolactin-secreting tumors), and certain fertility problems. Bromocriptine also helps manage Parkinson's disease symptoms by increasing dopamine activity in the brain.
The generic version works identically to brand-name Parlodel and contains the same active ingredient as brand-name drugs. It comes in tablet and capsule forms and is typically taken by mouth. Bromocriptine was developed in the 1970s and remains a trusted option for managing prolactin-related disorders and movement problems. Your healthcare provider may recommend bromocriptine if other treatments haven't worked or if you need a medication that targets dopamine pathways directly.

Side Effects
Bromocriptine is generally well-tolerated, but some people experience side effects, especially when starting the medication or increasing the dose. Most side effects are mild and improve as your body adjusts.
Common Side Effects
Nausea and vomiting – Occurs in many people, particularly with higher doses; taking the drug with food helps reduce this effect.
Dizziness and lightheadedness – May happen especially when standing up quickly or changing positions; avoid sudden movements.
Headaches – Usually mild and may decrease over time as your body adapts to the medication.
Fatigue – Some people feel tired or sluggish, particularly during the first few weeks of treatment.
Constipation – Less common but possible; drinking water and eating fiber can help manage this.
Abdominal cramps – Mild stomach discomfort may occur but typically resolves without intervention.
Serious Side Effects
Heart valve problems – Prolonged use at high doses may rarely cause thickening or damage to heart valves; your doctor may monitor this with imaging.
Severe drop in blood pressure – Can lead to fainting, chest pain, or serious dizziness; report sudden pressure changes immediately.
Hallucinations or confusion – Dopamine-affecting drugs may cause mental changes, especially in older adults or those with certain psychiatric conditions.
Severe headache with vision changes – May indicate a serious condition requiring immediate medical attention.
Chest pain or irregular heartbeat – Seek emergency care if you experience these symptoms while taking bromocriptine.
When to Seek Medical Attention
Contact your doctor if you experience persistent nausea, severe dizziness, unusual fatigue, or any mental health changes. Report chest pain, severe headaches, vision problems, or fainting immediately—these may need emergency evaluation.
If you notice swelling in your legs, shortness of breath, or a racing heartbeat, seek urgent care. Most side effects are manageable with dose adjustments or timing changes, so don't stop taking bromocriptine without talking to your healthcare provider first.

Important: Take bromocriptine exactly as prescribed. If you miss a dose, take it as soon as you remember unless it's close to your next scheduled dose—then skip the missed dose and continue your regular schedule. Never double up on doses. Do not stop taking bromocriptine without your doctor's approval, as stopping suddenly can cause your prolactin levels to rise or Parkinson's symptoms to worsen.
Drug Interactions
Bromocriptine may interact with several medications and substances, potentially reducing effectiveness or increasing side effect risk. Always inform your healthcare provider about all medications, supplements, and over-the-counter drugs you're taking.
Antipsychotics (Haloperidol, Risperidone, Olanzapine)
Antipsychotics block dopamine in the brain and may counteract bromocriptine's effects. Using both together may reduce the benefit of either medication or worsen psychiatric symptoms. Your doctor may need to adjust doses or choose alternative medications.
Blood Pressure Medications (Lisinopril, Metoprolol, Amlodipine)
Bromocriptine may lower blood pressure, and combining it with blood pressure-lowering drugs could cause excessive drops. This increases dizziness, fainting, or heart-related complications. Your doctor may monitor blood pressure more closely or adjust doses.
Ergot Alkaloids (Ergotamine, Dihydroergotamine)
Both bromocriptine and ergot alkaloids cause blood vessel constriction. Taking them together raises the risk of severe blood pressure spikes, stroke, or heart problems. These combinations are typically avoided unless closely supervised.
Metoclopramide (Reglan)
Metoclopramide blocks dopamine and may reduce bromocriptine's effectiveness. This combination may be necessary for some patients but requires careful monitoring and possible dose adjustments to maintain therapeutic benefit.
Oral Contraceptives and Estrogen
Estrogen can increase prolactin levels and may reduce bromocriptine's effectiveness at lowering prolactin. Your doctor may recommend adjusting bromocriptine dose or choosing alternative birth control options.
Sympathomimetic Drugs (Pseudoephedrine, Phenylephrine, Amphetamines)
These medications stimulate the nervous system similarly to dopamine and may cause excessive stimulation, increased heart rate, or dangerous blood pressure elevation when combined with bromocriptine.

Frequently Asked Questions
Bromocriptine treats conditions caused by high prolactin levels, including hyperprolactinemia, prolactinomas (prolactin-secreting tumors), and fertility problems. It's also used to manage Parkinson's disease by increasing dopamine activity in the brain. Understanding generic vs. brand-name drugs helps you see that generic bromocriptine works identically to brand-name Parlodel for all these conditions.
Bromocriptine typically begins working within days to weeks, but it may take 2–3 months to see full benefits, especially for Parkinson's disease. Prolactin levels usually drop within the first week, but symptoms may take longer to improve. Your doctor may gradually increase your dose over several weeks to achieve the best results.
Alcohol may worsen dizziness, nausea, and fainting—common side effects of bromocriptine—and should be avoided or limited. Alcohol may also reduce the medication's effectiveness and increase blood pressure fluctuations. Discuss safe alcohol use with your healthcare provider based on your specific situation.
Bromocriptine may be used during pregnancy in some cases, particularly for prolactinomas, but risks and benefits must be carefully discussed with your doctor. Prolactin-secreting tumors sometimes grow during pregnancy, and bromocriptine may help prevent complications. However, your doctor must weigh these benefits against potential risks to the developing baby.
Take the missed dose as soon as you remember unless it's close to your next scheduled dose. If it's nearly time for your next dose, skip the missed one and resume your regular schedule. Never double up on doses to make up for a missed one, as this increases side effect risk and may cause dangerous blood pressure changes.
The Bottom Line
Bromocriptine is a dopamine agonist that effectively lowers prolactin levels and treats Parkinson's disease by increasing dopamine activity in the brain. The generic version offers the same benefits as brand-name Parlodel at a lower cost, making it an accessible option for most patients. While common side effects like nausea and dizziness usually improve over time, serious effects like heart valve changes and blood pressure fluctuations require careful monitoring. With gradual dose increases, regular blood pressure checks, and open communication with your doctor about any concerns, bromocriptine can be a safe and effective treatment.
