i have trouble sleeping at times and once took a mogadon which seemed to work much better than the apo-nitrazepam I got from the pharmacy ## Hello, Mike! How are you? They are the same medication, Mogadon is just a brand name for it. Side effects may include nausea, dizziness, headache and irritability, this medication also carries the risk of being habit forming. How long have you been taking it? Are they both the same formulation?
