Is clonazepam available in the US?

Could you please clarify for me, is clonazepam, also known as Klonopin, readily available for purchase and use in the United States? I understand it's a medication used to treat certain conditions like anxiety and seizures, but I'm curious about its accessibility within the country's borders. Additionally, would there be any restrictions or special considerations that one needs to be aware of before attempting to obtain or use this medication?
