About Fensant-100 Injection 2ml

Fensant-100 Injection 2ml is a prescription medication given by injection to control and prevent severe, continuous seizures. It is also used to prevent or treat seizures that may occur during or after brain surgery. This medicine belongs to a class of drugs known as anticonvulsants, which help stabilise abnormal electrical activity in the brain.

Because this medicine is given as an injection, a healthcare professional will give it to you in a hospital or clinic setting. The frequency of your doses will depend on your specific medical condition and how you respond to the treatment. Maintaining a regular sleep schedule and avoiding stressful triggers can support your recovery during therapy.

While using Fensant-100 Injection 2ml, you may experience common side effects like dizziness, sleepiness, or mild coordination issues. However, you must seek immediate medical attention if you notice serious signs such as severe skin rashes, yellowing of the eyes or skin, or unusual bruising. Your healthcare team will closely monitor you during and after the injection to catch any adverse reactions early.

Before starting treatment, tell your doctor if you have a history of liver damage, heart rhythm problems, or diabetes. Do not receive this medicine if you have had a severe allergic reaction to it or similar seizure medicines in the past, or if you have certain slow heart rate conditions.

This medication can interact with alcohol, which may increase drowsiness, and with other medicines that affect liver enzymes, potentially altering the drug's levels in your blood. If you are pregnant, breastfeeding, or an elderly individual, consult your doctor as this treatment requires careful monitoring and dose adjustments to ensure safety.

How Fensant-100 Injection 2ml Works

Fensant-100 Injection 2ml contains phenytoin. Phenytoin belongs to a group of medicines called antiepileptics (medicines used to prevent and control seizures). It works by blocking voltage-gated sodium channels (proteins in nerve cells that help generate and transmit electrical signals). This reduces the rapid, repetitive electrical activity that causes seizures and prevents abnormal nerve signals from spreading through the brain. As a result, brain activity becomes more stable, helping to control and prevent seizures.
