I recently started getting actavis 2 mg alprazolam and it had no effect. The pharmacy used to carry sandoz and that worked well. Recently noticed that the factory sealed bottles that I get every month had alprazolam 2mg on the front but on the back it had alprazolam 2 mg . Has anyone else seen this? How could quality control miss this? It comes from a reputable pharmacy so could a huge pharmacy chain get a counterfeit prescription or is it just a mistake? If not a mistake then it’s just not effective at all. Does anyone know how this could happen and any way to contact the manufacturer and find out?
