Lonazep 1 MG Description

Lonazep 1mg injection is an anticonvulsant/anti-epileptic injection used to control seizures (fits) and relieve symptoms of anxiety and panic disorders. It belongs to the Benzodiazepine group of medi

cines and is chemically composed of Clonazepam. It is a prescription medicine. Clonazepam acts on GABA-A receptors (gamma-aminobutyric acid) in the brain and inhibits the excessive activity of the brain, suppressing seizures. It produces sedation and drowsiness and relieves anxiety. Epilepsy or seizure is a sudden uncontrollable excessive nerve activity in the brain associated with movements and changes in your consciousness. A panic disorder is a sudden intense fear of something when there is no cause or real danger. Your doctor can only start Lonazep 1mg injection after he has confirmed your illness. Your doctor will recommend the dose and duration of the injection. The common side effects of Lonazep 1mg injection are sedation, drowsiness, loss of coordination, fatigue, memory problems, tremors, visual disturbances, confusion, urinary problems, palpitations, dehydration, chest discomfort and running nose. Do not stop the medicine abruptly or skip the dose, or overdose. Sudden stoppage of the injection can result in seizures and withdrawal symptoms like pain in the abdomen, tremors, hallucinations and behavioral disorders. If you develop any severe allergic reaction following the injection or persistent symptoms, please report to the emergency immediately. The doctor might advise you to undergo regular blood count evaluation and liver function tests if you take the injection for a longer duration.
