Side Effects and Cautions

• Hawthorn is considered safe for most adults when used for short periods of time. Side effects are usually mild and can include upset stomach, headache, and dizziness.
• Drug interactions with hawthorn have not been thoroughly studied. It was once thought that hawthorn interacted with the heart medicine digoxin. However, a very small study in people without heart conditions found no interaction, but evidence is limited.
• 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.
