Benefits of Lorazen Injection
Treatment of Status epilepticus
Status epilepticus is when a seizure lasts longer than 5 minutes or when seizures occur close together and the person doesn't recover between seizures. It is a medical emergency and needs immediate medical attention. Lorazen Injection slows down electrical signals in the brain which cause seizures (fits). It can also help reduce symptoms such as confusion, uncontrollable jerking movements, loss of awareness, and fear or anxiety. It is given as an injection by a doctor or nurse.

Treatment of Anxiety disorder
Lorazen Injection helps relieve symptoms of many anxiety disorders including obsessive-compulsive disorder and generalised anxiety disorder by increasing the level of a chemical called GABA in your brain. This prevents abnormal symptoms of anxiety such as restlessness, tiredness, difficulty concentrating, feeling irritable and sleep problems. It helps you feel calm with a better ability to deal with problems. Exercise and a healthy diet can also improve your mood. Keep taking the medicine until your doctor advises you to stop.
