Both horsetail and oral dexamethasone can promote the loss of potassium from the body. Signs of low potassium are difficult to observe, but they can include muscle cramps, weakness, excessive thirst, and frequent urination. Very low potassium levels can cause dangerous changes in heartbeat. Inform your doctor before taking dexamethasone with horsetail or any other herbal supplement. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
