Dostinex dosage: simple, practical dosing for cabergoline

Dostinex (cabergoline) is a strong dopamine agonist used mostly for high prolactin levels. A little pill can have a big effect, so dosing is cautious and gradual. Below you’ll find common starting plans, how doctors usually adjust doses, what to watch for, and practical tips to reduce side effects.

Typical dosing for hyperprolactinemia

Most prescribers start low and go slow. A common approach is 0.25 mg twice a week (for example, Monday and Thursday) for the first 2 weeks. If tolerated, the dose is often increased to 0.5 mg twice weekly. Many people do well on 0.5–1 mg per week; some need up to 2 mg per week. Your doctor will pick a schedule that fits your test results and symptoms.

Why twice weekly? Cabergoline has a long half-life, so twice-weekly dosing keeps levels steady without daily pills. If your prolactin stays high or symptoms persist, your clinician may slowly raise the dose. For fertility or menstrual issues, doses are usually low; for other conditions, different regimens apply under specialist care.

Short notes on other uses and limits

For stopping milk production after birth, some protocols used a single 1 mg dose within the first day postpartum. That approach varies by country and clinician; check current local guidance before using it. Higher doses have been used for Parkinson’s disease in the past, but that requires specialist management and heart monitoring because of valve risks.

Always talk with your prescriber before changing doses. If you miss a scheduled dose, take it as soon as you remember unless the next dose is due within 48 hours—then skip and continue the regular schedule. Don’t double up.

Blood tests and monitoring matter. Doctors usually check baseline prolactin, then recheck after 4–6 weeks to judge response. If doses go above typical ranges or symptoms suggest heart issues, an echocardiogram may be ordered because long-term high-dose cabergoline has been linked to valve changes.

Common side effects are nausea, headache, dizziness (especially on standing), and tiredness. Taking Dostinex at night and with a small snack often reduces nausea and dizziness. Avoid driving or heavy machinery until you know how it affects you. If you feel faint, sit or lie down and contact your healthcare provider.

Interactions and special situations: cabergoline can amplify blood-pressure-lowering drugs and other dopamine-active medicines. If you have uncontrolled heart disease, severe liver problems, or certain psychiatric conditions, mention that—your doctor may choose a different treatment.

Bottom line: start low, check prolactin, and adjust slowly. Small, spaced doses usually do the job with fewer side effects. If anything feels off—new chest symptoms, fainting, sudden swelling—get medical advice right away. Your prescriber will tailor the exact plan to your tests, goals, and overall health.
