- Initial dose: 0.5 mg taken twice a week.
- Maintenance dose: Adjusted based on clinical response and prolactin levels, typically ranging from 0.5 mg to 1 mg per week.
- For some individuals, increased dosages may be necessary, as directed by a healthcare provider.
Expected Results
Patients using Dostinex can expect the following results:
- Reduction in prolactin levels, often within a few weeks of starting treatment.
- Improvements in symptoms related to hyperprolactinemia, such as menstrual irregularities and infertility.
- In some cases, a reduction in size of pituitary tumors associated with high prolactin levels.
Potential Side Effects
While Dostinex is generally well-tolerated, it is crucial to be aware of possible side effects, which can include:
- Nausea
- Headaches
- Dizziness
- Fatigue
- Constipation

In conclusion, Dostinex 0.5 mg is an effective treatment option for conditions associated with elevated prolactin levels. With appropriate usage and monitoring, many patients can achieve significant improvements in their symptoms.
