Bromocriptine: What it’s for and what to watch for

Did you know bromocriptine started as a Parkinson's drug but is now often used to treat high prolactin levels? If someone suggested bromocriptine to you, this page tells you what it does, how people usually take it, and the common problems to watch for—without medical jargon.

How bromocriptine is used

Bromocriptine is a dopamine agonist. Doctors prescribe it mainly for:

- Hyperprolactinemia (high prolactin): it lowers prolactin to stop unwanted milk production, restore periods, or treat infertility related to prolactin.

- Parkinson’s disease: it can help with motor symptoms, often alongside levodopa.

- Type 2 diabetes (in some regions): a quick-release low-dose form (brand name Cycloset) can help blood sugar control for certain patients.

Different conditions need different doses. That’s why you should follow your doctor’s plan rather than copying someone else’s dose.

Practical dosing, effects and warnings

Typical dosing starts low and goes up slowly. For prolactin problems doctors often start with 1.25 mg once a day or every other day, then increase as needed. Parkinson’s doses are usually higher and set by a neurologist. Diabetes-type dosing is a specific low, once-daily morning tablet.

Common side effects are nausea, dizziness, lightheadedness (especially when standing), headache, and constipation. These often ease after a few days. To reduce nausea, take the pill with food and start with a very low dose.

Watch for these more serious signs and call your doctor: fainting, chest pain, new or severe mental changes (hallucinations, intense mood swings, or gambling/impulse behavior), or sudden shortness of breath. Bromocriptine can affect blood pressure and mood, so monitoring is important.

Interactions to know: antipsychotics and some anti-nausea drugs that block dopamine can cancel bromocriptine’s effect. Strong CYP3A4 inhibitors (some antifungals, certain antibiotics) can raise bromocriptine levels—tell your prescriber about all medicines and supplements you take. Don’t use bromocriptine if you want to breastfeed; it stops milk production.

Quick safety tips: lie down for the first dose if you worry about fainting, take with food to cut nausea, and avoid driving until you know how it affects you. Keep regular follow-up visits to check blood pressure, symptoms, and hormone levels if used for prolactin issues.

If you’re unsure whether bromocriptine fits your needs, talk to your doctor or pharmacist. They can explain dose changes, side effect management, and monitoring steps specific to your health. If you suspect a serious reaction, seek medical help right away.
