Cabergoline Tablets: Uses, Dosage, Side Effects & More
Learn about cabergoline tablets, their uses, dosage, side effects, and important safety information.
What Is Cabergoline?
Cabergoline is a medication classified as a dopamine agonist, which means it activates certain dopamine receptors in the brain. It is primarily used to treat conditions associated with high levels of the hormone prolactin, a condition known as hyperprolactinemia. Cabergoline is available in tablet form and is taken orally, usually under the supervision of a healthcare provider.
How Does Cabergoline Work?
Cabergoline works by mimicking the action of dopamine, a neurotransmitter in the brain. Dopamine normally inhibits the release of prolactin from the pituitary gland. By activating dopamine receptors, particularly the D2 receptors, cabergoline reduces the production and release of prolactin. This helps restore hormonal balance and alleviate symptoms associated with excess prolactin.
Uses of Cabergoline Tablets
- Hyperprolactinemia: Cabergoline is used to treat high levels of prolactin in the blood, which can cause menstrual irregularities, infertility, and unwanted milk production (galactorrhea).
- Prolactinomas: It is effective in treating prolactin-secreting pituitary tumors, helping to shrink the tumor and normalize prolactin levels.
- Fertility Issues: Cabergoline can help restore fertility in both men and women affected by high prolactin levels.
- Menstrual Disorders: It is used to treat amenorrhea (absence of menstruation) and oligomenorrhea (infrequent menstruation) caused by hyperprolactinemia.
- Suppression of Lactation: Cabergoline can be used to prevent or stop milk production in women who do not wish to breastfeed.
Dosage and Administration
The dosage of cabergoline varies depending on the condition being treated and the individual patient. It is important to follow the prescribed dosage and instructions provided by a healthcare professional.
Typical Dosage for Adults
| Condition | Starting Dose | Maintenance Dose |
|---|---|---|
| Hyperprolactinemia | 0.25 mg twice a week | 0.25 mg to 2 mg per week |
| Prolactinoma | 0.25 mg twice a week | 0.25 mg to 2 mg per week |
| Suppression of Lactation | 1 mg on the first day after delivery | As directed by physician |
The dose may be adjusted based on the patient’s response and prolactin levels. Cabergoline is usually taken with food to minimize gastrointestinal side effects.
