I Had A Reaction To Primidone When My Pharmacy Changed

I had a reaction to Primidone when my Pharmacy changed generics . My neurologist told them this might happen if they switched companies and generics on my Primidone . I have terrible feelings of withdrawal from from this Company's Primidone . My Pharmacist states this would not happen as all generics are alike no matter what Company. What are your feelings on this.I have told my neurologist . I was told your company would not be making this generic Primidone . Is this true? I have been on this drug for multiple years. I am being worked off. Will I have more problems using another company's Primidone generic.
