Phentin 300 SR Tablet used to treat epilepsy/seizures, and prevent seizures during/after brain surgery or after traumatic brain injury. Besides this, Phentin 300 SR Tablet may also be used to treat trigeminal neuralgia (facial nerve pain). Epilepsy is a central nervous system disorder characterized by a sudden rush of electrical activity in the brain, leading to seizures, unusual behaviour, and loss of awareness.

Phentin 300 SR Tablet contains 'Phenytoin', which helps prevent neurons from working at a very fast speed, thereby preventing the brain cells from firing together rapidly in an uncontrolled way. As a result, Phentin 300 SR Tablet controls the overactivity of the brain cells that cause seizures. Phentin 300 SR Tablet slows down the electrical impulses in the nerves and reduces their ability to transmit pain. Thereby treating trigeminal neuralgia.

Take Phentin 300 SR Tablet with or without food. You are advised to take Phentin 300 SR Tablet for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, Phentin 300 SR Tablet may cause certain common side effects such as weakness, drowsiness, dizziness, restlessness, and constipation.

Phentin 300 SR Tablet is also used to control and prevent fits during or after a severe head injury or brain surgery. Phentin 300 SR Tablet works by controlling the overactivity of the brain cells that cause seizures (fits). Thereby, Phentin 300 SR Tablet helps in controlling epileptic fits involving spasms of the muscles and jerking. Phentin 300 SR Tablet may also be used to treat trigeminal neuralgia (facial nerve pain). Phentin 300 SR Tablet slows down the electrical impulses in the nerves and reduces their ability to transmit pain. Thereby treating trigeminal neuralgia.

Epilepsy/Seizures: Seizures, also known as fits or convulsions, are a single occurrence of abnormal electrical activity in the brain, whereas epilepsy is a chronic neurological disorder characterised by recurrent seizures. The possible causes of epilepsy include traumatic brain injury, scarring on the brain after a brain injury, high fever, stroke, vascular diseases, lack of oxygen to the brain, brain tumours, and genetic disorders. Symptoms include mood changes, anxiousness, nausea, dizziness, weakness, headache, muscle jerking, spasms, loss of balance, teeth clenching, rapid blinking or eye movements, biting the tongue, confusion, and loss of consciousness.

Trigeminal neuralgia: It is a condition affecting the trigeminal nerve in the face that causes painful sensations similar to electric shock on one side of the face. Symptoms include mild to severe facial pain often triggered by speaking, chewing, or brushing the teeth.
