Side Effects and Cautions

• Chasteberry has not been associated with serious side effects. However, it can cause gastrointestinal problems, acne-like rashes, and dizziness.
• Chasteberry may affect certain hormone levels. Women who are pregnant or taking birth control pills or who have a hormone-sensitive condition (such as breast cancer) should not use chasteberry.
• Because chasteberry may affect the dopamine system in the brain, people taking dopamine-related medications, such as selegiline, amantadine, and levodopa, should avoid chasteberry.
• Tell your health care providers about any complementary and alternative practices you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
