🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by blocking sodium channels in nerve cells, which reduces the repeated firing of brain cells that can lead to seizures. It also increases the activity of the calming neurotransmitter GABA and reduces the activity of the excitatory neurotransmitter glutamate. In addition, it inhibits carbonic anhydrase enzymes, which may contribute to some of its effects and side effects. These actions together help stabilize electrical activity in the brain and reduce the frequency of seizures and migraine attacks.

Dosage Information
| Adult Dosage | The dose of this medicine is individualized by a qualified clinician based on the condition being treated, age, weight, kidney and liver function, and other medicines being taken. For epilepsy, treatment is usually started at a low dose, such as 25 mg to 50 mg once or twice daily, and increased gradually over several weeks to the lowest effective dose. For migraine prevention, the usual starting dose is 25 mg once daily at night, increased slowly to a maximum of 100 mg per day in divided doses. The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not change the dose without medical advice. |

Consult a pediatrician for appropriate dosing. |
| Elderly Dosage | Elderly patients may be more sensitive to the side effects of this medicine, especially drowsiness, dizziness, and difficulty with concentration. The dose is usually started low and increased slowly. Kidney function should be checked before and during treatment, as reduced kidney function is common in older adults and may require a lower dose. Dose must be individualized by a qualified clinician. |

Your doctor will check your kidney function and adjust the dose accordingly. Dose must be individualized by a qualified clinician based on renal function. |
| Hepatic Impairment | This medicine is not extensively metabolized by the liver, but people with liver disease may be more sensitive to its effects. The dose may need to be adjusted and liver function monitored. Dose must be individualized by a qualified clinician based on hepatic function. |

If you become pregnant while taking this medicine, contact your doctor immediately. Do not stop the medicine suddenly, as seizures can be harmful to both you and your baby.
