Tegretol® 100 mg/5 mL Oral Suspension contains carbamazepine, a medicine used to treat certain neurological conditions. Doctors commonly prescribe this medication to help control epileptic seizures and manage nerve-related pain.
Carbamazepine acts on the central nervous system. It stabilizes nerve activity and reduces abnormal electrical signals in the brain. As a result, the medicine helps control seizures and decreases nerve pain.

Doctors may also prescribe Tegretol oral suspension to manage conditions such as trigeminal neuralgia and bipolar disorder in certain patients. In addition, the liquid formulation makes it easier for patients who have difficulty swallowing tablets.
The medicine is taken by mouth (orally) as prescribed by a healthcare professional.
Each 5 mL of oral suspension contains:
Carbamazepine – 100 mg
The formulation also contains inactive ingredients (excipients) that help maintain stability, improve taste, and ensure proper suspension consistency.
Carbamazepine belongs to a group of medicines known as anticonvulsants.
The medicine works by stabilizing overactive nerve signals in the brain. It blocks certain sodium channels in nerve cells. Consequently, abnormal electrical impulses decrease.
This action helps:
Control epileptic seizures
Reduce nerve pain
Stabilize mood fluctuations in some patients
Therefore, carbamazepine supports normal electrical activity in the brain and nervous system.
