Carbamazepine
Summary
Carbamazepine is used to treat epilepsy, which is a condition causing seizures, and bipolar disorder, which involves mood swings. It also helps with nerve pain, which is pain from nerve damage.
Carbamazepine stabilizes electrical activity in the brain, which helps prevent seizures and stabilize mood. It acts like a traffic light, controlling nerve signals to prevent them from becoming too fast or erratic.
Carbamazepine is usually taken by mouth, two to four times a day, with meals to reduce stomach upset. The starting dose for adults is typically 200 mg twice daily, with adjustments based on response.
Common side effects of Carbamazepine include dizziness, drowsiness, and nausea, which are unwanted reactions to the medication. These effects occur in more than 10% of users.
Carbamazepine can cause serious skin reactions, especially in people of Asian descent, and may affect blood cell counts. It should not be used by those with bone marrow depression or allergies to it.
