Bottom line

Read Off Label grades Cabergoline as B (6.8/10) based on strong evidence, strong benefit magnitude, and a med-risk safety profile.

Valvulopathy risk is real and dose-dependent — chronic Parkinson's-level dosing (3+ mg/day) is clearly associated; prolactinoma doses less certain.

Studied, labeled, or reported-use context: 0. — Rx; not individualized guidance.

What the evidence says

Valvulopathy risk is real and dose-dependent — chronic Parkinson's-level dosing (3+ mg/day) is clearly associated; prolactinoma doses less certain. Biohacker microdoses (0.25 mg weekly) are much lower than valvulopathy-risk dosing but long-term safety data in that population doesn't exist. Echocardiographic monitoring is described in some product-label and specialty-guideline contexts, with practices varying by dose, indication, duration, and jurisdiction.

Mechanism

Ergot-derived long-acting D2 dopamine receptor agonist; suppresses prolactin; used medically for hyperprolactinemia, prolactinoma, Parkinson's; off-label for post-orgasmic refractory reduction

Studied, labeled, or reported dose & route

0.25-0.5 mg once weekly (low-dose biohacker); 0.25-1 mg 2x/week (hyperprolactinemia)

This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.

Common questions

What does the evidence show about Cabergoline's effects?
Read Off Label rates the evidence for Cabergoline as Strong and the benefit magnitude as strong, producing an overall grade of B (6.8/10). Valvulopathy risk is real and dose-dependent — chronic Parkinson's-level dosing (3+ mg/day) is clearly associated; prolactinoma doses less certain.
What safety findings are reported for Cabergoline?
Cabergoline has a med risk profile in the database. Med (cardiac valvulopathy with high chronic doses — well-documented in Parkinson's and pituitary dosing; nausea; orthostatic hypotension; compulsive behaviors) Legal status: Rx (Dostinex).
What doses or routes are reported for Cabergoline?
0.25-0.5 mg once weekly (low-dose biohacker); 0.25-1 mg 2x/week (hyperprolactinemia) This is context from studies, approved labeling, clinical practice, or documented use; it is not individualized guidance and does not establish safety.
How does Cabergoline work?
Ergot-derived long-acting D2 dopamine receptor agonist; suppresses prolactin; used medically for hyperprolactinemia, prolactinoma, Parkinson's; off-label for post-orgasmic refractory reduction
