Xanax from Pfeizer - I take for years because it only helps me, 1.5 mg to 2 mg By the fact that there is another manufacturer namely Upjohn EESV Xanax does not work. I can take 3 tablets at once and I won't even yawn. THIS is some kind of scandal! I immediately ask Mrs. Magister to do something about it, I can not sleep without this drug.

Sometimes it is so that after changing the composition of excipients, the drug acts differently on the body. However, I analyzed the composition of the excipients of both Xanax drugs - the previous Pfizer and the current one from Upjohn and they are identical. So, I don't know, there may be a difference from that. Perhaps the body has developed a tolerance to the drug and it will be necessary to increase the dose or change the method of treatment - here you should consult a doctor. If, after all, you connect the lack of effect of therapy with a change of manufacturer - you should report it to the appropriate institutions. I am afraid that the situation should be reported directly to the manufacturer. You can report such cases here: https://www.viatris.pl/pl-pl/o-nas/zglaszanie-dzialan-niepozadanych
I have the same thing. And it's not any greater tolerance. This drug is different after changing the manufacturer!
