There have been reports of blood pressure being lowered by CES so care should be taken in treating patients on high blood pressure medication. CES treatment at higher than necessary currents may cause dizziness or nausea that is usually transient, but can sometimes last for hours to days. Treatment immediately prior to going to sleep may cause difficulty sleeping due to increased alertness. It is recommended that CES be used at least 3 hours before going to sleep. Paradoxical reactions such as hyperexcited states, increased anxiety, and sleep disturbances are rare, but may occur.
