... Mysoline only. Just over three years ago I started having minor seizures (partial) and 'absence attacks', which I hadn't had for 6 years. I had always received Mysoline in their branded box, but was given them in a 'brown' bottle and told by the pharmacist 'they are the same' to which I replied they weren't. My doctor said the drug was the Mysoline brand, but I was convinced they weren't due to the attacks receiving. He suggested changing to LAMOTROGINE to control the absence attacks, which I did. However, the side effects were really bad - insomnia and blood poisoning being the worst, which caused a grand mal attack when I was hospitalised. My neurologist told me I had been given generic medication and after MRI scans said I was to go back onto Mysoline 50mg increasing to 250mg 3 times a day. This I did and feel much better and will never stop taking Mysoline as they are the only medication I can rely on to stop my attacks. I do not know why the generic Primidone is the same name as SERB Mysoline, but I have read a report (internet), which states when SERB (in France) would buy the UK business, which made Mysoline, and make it using the correct compound if they could change the name to Primidone. As both branded and generic mysoline look the same how can I tell the difference ? I would be most grateful to anyone who could shed light on this.
