About Oxcarbazepine 300 mg
Oxcarbazepine 300 mg tablet is a Selective serotonin reuptake inhibitor (SSRI) antidepressant used for depression, anxiety, and sometimes panic attacks, obsessive-compulsive disorder (OCD), or social anxiety. It works by stopping the brain from quickly reabsorbing the lost serotonin from its nerve ending to make an individual stay happy, improve mood, and reduce anxiety. Common side effects include nausea, headache, sleep changes, dry mouth, and sexual difficulties. It can be taken with or without food, but alcohol may increase drowsiness, and grapefruit juice is best avoided. Store at room temperature, away from heat, moisture, and children.

How Oxcarbazepine 300 mg works
Oxcarbazepine 300 mg tablet works by calming overexcited brain cells in epilepsy. Normally, these cells can become overloaded with electrical charge, like balloons filled with too much water—making them prone to bursting into seizures when triggered. Oxcarbazepine 300 mg blocks sodium channels, preventing excessive entry of charged ions into the brain cells. This stabilizes their activity, reduces the risk of sudden electrical surges, and helps prevent seizures and tremors.
