Dostinex is a generic name for cabergoline, a dopamine promoter that reduces high levels of prolactin in the blood.
How It Works
Cabergoline, the active ingredient in Dostinex, is a chemical that can block the release of prolactin from the pituitary gland. Prolactin is a hormone which is elevated by certain conditions. Prolactin levels naturally go up in pregnant and nursing women. In both women and men, the level of this hormone can go up due to emotional or physical stress. Problems in the pituitary gland, such as tumors, may cause prolactin levels in the blood to be abnormal.
Medications like Dostinex can bring down elevated prolactin levels in the blood to the normal range.
Dostinex is prescribed to treat hyperprolactinemia, the medical term for high levels of prolactin in the blood not caused by pregnancy. This condition is more common in women than men. Women with hyperprolactinemia may have trouble getting pregnant, experience changes or ceasing of ovulation, miss periods, and may also suffer from galactorrhea (breasts producing milk when not pregnant). Hyperprolactinemia also disrupts normal production of other hormones like estrogen and progesterone.
Hyperprolactinemia also affects men, who can also experience galactorrhea, suffer from impotence, dulling of the sex drive and infertility.
Dostinex is prescribed to treat such conditions in women and men.
The dosage of Dostinex should be prescribed by a physician. Dosage will vary depending on the condition being treated, gender of the patient and the severity of prolactin levels in the blood. Dostinex is prescribed only after testing the blood for prolactin levels.
Dostinex should be taken by the mouth, if needed with some water. The medication can be taken with or without food. Dostinex is usually prescribed to be taken twice a week.
It’s normal for doctors to instruct patients to take Dostinex at a low dose and gradually increase the dosage to a desired volume. This prevents the patient from suffering from serious side effects.
Follow the dosage exactly as instructed.
It’s important to take Dostinex regularly as instructed. Mark down the days you should take Dostinex on a calendar to avoid forgetting a dose.
Dostinex may cause one or more of the following side effects:
Rare but serious side effects of Dostinex include shortness of breath, persistent cough, swelling of ankles or, unusual tiredness, mood changes, unusually strong urges to engage in compulsive behavior like gambling or sex, vision changes, breast pain or painful menses. Immediately seek medical care if any of these side effects occur.
Do not take Dostinex if known to be allergic to cabergoline or similar ergot medications.
