Cabergoline
A long-acting dopamine agonist that lowers prolactin, used to manage hyperprolactinemia and related sexual dysfunction. High chronic doses carry a cardiac valve risk.
- Half-life
- 2.7 d
- Out of system
- ~14 days
- Route
- Oral
- Level
- Advanced
Levels carry over between doses — every 2–3 days is typical. After the last dose, roughly 97% has cleared in ~14 days (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Cabergoline is used for
- Lowers elevated prolactin, restoring libido and sexual function
- Long half-life allows convenient twice-weekly dosing
- Effective for prolactin-secreting conditions and related dysfunction
How it's typically used
Literature range: 0.25 mg orally twice weekly for prolactin control, titrated per response as reported in the research.
What to watch for
- High chronic doses carry a risk of cardiac valve fibrosis (valvulopathy)
- Can cause nausea, dizziness, low blood pressure and impulse-control effects
- Prescription dopamine agonist; use only under medical supervision
About Ancillaries (SERMs / AIs)
- What they are
- Support drugs — SERMs, aromatase inhibitors, and prolactin controls used to manage the side effects of androgen use or to restart natural production afterwards.
- How they're run
- Oral tablets, dosed against bloodwork rather than on a fixed schedule.
- What to watch
- These are only meaningful with labs in hand. Crushing oestrogen with an AI wrecks joints, libido, and lipids just as thoroughly as having too much of it.
