No....... you cannot get this OTC for this medicine requires a doctors Rx in order to obtain it.

My daughter (God rest Her Soul) - took Pentobarbital in liquid form for her seizures.... this medicine is often used to depress brain activity when seizures are out of control. My daughter was even given this as an IV Drip to induce a coma to stop multiple seizures that were still going strong after 72 hours (3 days) - the induced coma lasted 3 weeks.
