More Information

What is Carbamazepine?

Carbamazepine is a pharmaceutical medication primarily used as an anticonvulsant (which prevents seizures) and mood stabilizer. Meds for Less offers three strengths of Carbamazepine:

i) Carbamazepine 100mg

ii) Carbamazepine 200mg

iii) Carbamazepine 400mg

It is commonly prescribed to treat epilepsy, trigeminal neuralgia, and bipolar disorder. Carbamazepine works by regulating electrical activity in the brain, reducing the frequency and severity of seizures in individuals with epilepsy.

It is important to note that carbamazepine may have side effects and interactions with other medications, so it should be taken under the guidance and supervision of a healthcare professional. Furthermore, you can also use a carbamazepine drug interaction checker as an additional resource.


 How does Carbamazepine work

i) Carbamazepine & Seizures:  It works by stabilizing the electrical activity in the brain, specifically by blocking sodium channels. By doing so, carbamazepine prevents excessive electrical signals from spreading rapidly in the brain, thus reducing the occurrence of seizures.

ii) Carbamazepine as a mood stabilizer: Carbamazepine is also utilized as a mood stabilizer in the treatment of bipolar disorder. Its precise mechanism of action in this context is not fully understood, but it is believed to involve the modulation of neurotransmitters such as dopamine and serotonin.

iii) Carbamazepine & Nerve Pain: In the case of nerve pain such as trigeminal neuralgia, carbamazepine stabilizes the electrical signals within the nerves, effectively interrupting the transmission of pain signals to the brain. This mechanism of action disrupts the pathway in which pain signals are relayed, resulting in pain relief.
