Rivotril 2mg is a brand name for the medication clonazepam. Clonazepam is a benzodiazepine that is commonly used to treat anxiety disorders, panic attacks, and seizures. It works by enhancing the effects of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA), which helps to calm the nerves and reduce anxiety. Rivotril 2mg is available in tablet form and should only be taken under the supervision of a healthcare professional, as it can be habit-forming and may cause drowsiness or other side effects.
