Re: Tammy (# 29)
I just started researching different manufacturers of Alprazolam and am really worried about anything other than Greenstone. Do you know the best source of information about the differences in each manufacturer's pill -- possible side effects, etc? I've taken .5 mg for decades and a year ago cut back from 3 pills over a 24-hour period to one (and sometimes none). I'd like to get off it completely, but...

Greenstone will be on the same level as original Xanax, however I found greenstone to be more potent. Try it

Re: Mike (# 26)
I took Xanax like 20 years ago with no problems and have been on ativan for like 18 years and the only mfr that works for me is Watson and now Watson is gone. Thus, I recently switched to Xanax and I took a 1/4 of a (.5) and had a 3 hour panic attack. Isn’t this the polar opposite of what Xanax is supposed to do? Anyone else have a similar experience with Xanax?

Re: Airsk8hed (# 5)
The FDA + / - tolerances are meaningless as they are not always practiced by industry due to the poor quality control at some generic manufacturers. Some pharmaceutical companies even intentionally manufacture to the low end of the allowed active ingredient range to make more money. Patients suffer. Several of my physician friends have shown me peer reviewed studies proving that most generics have poorer quality control. Aurobindo was caught hiding defective batches from FDC where the bad batches were distributed and could not be traced for recall. Buyer beware.

So you feel like the Green Dava/Par 2mg generic “S 90 3” tablets aren’t that sedating either?

Re: Joseph (# 17)
You are incorrect as Jay says. There ABSOLUTELY is a difference between regular generics and an Authorized Generic. As a matter of fact, speaking of the FDA, they have two different books to distinguish between Authorized Generics (Drugs with IDENTICAL chemical formula to its brand-named counter-part), and “The Orange Book,” for: Approved Drug Products with Therapeutic Equivalence Evaluations. #KnowledgeIsPower #KnowYourDrugs

UpJohn Pharmaceutics merged with Pharmacia AB to form: “Pharmacia & Upjohn”, which was owned by Pfizer between 2015-2020, and was known for producing the Brand Name Xanax 2mg Tablets. They now go by Viatris; still a subsidiary of Pfizer.

Re: Joseph (# 17)
They absolutely are not the same. An authorized generic is classified under the same NDA of it’s brand name. It has a totally different distinction than a generic drug. A generic drug has to prove bio equivalence whereas an authorized generic does not. Also, generic drugs have the same active ingredient but different manufacturers all have different fillers. Lastly, in order for a generic drug to meet bio equivalent requirements of the brand drug, the FDA allows for up to a 20% variation in the active ingredient from that of the original formula. Stop spreading misinformation. Do your research.

Re: Joseph (# 16)
If you do your research, you’ll find that upjohn’s Xanax formula was ultimately obtained by Pfizer - which is Greenstone. Greenstone alprazolam is the exact same chemical formulation as Upjohn.

Re: Davemp88 (# 13)
All generics are identical, all have the same active ingredient. I really don't understand the public's fear of generics. There's no such thing as an "authorized". They are all authorized by the FDA.

Re: Davemp88 (# 13)
Correct, Greenstone is Pfizer's generics division. Upjohn was the pharmaceutical company that developed Alprazolam and gave it the brand name of Xanax. All generics are the same, that 10% Waxman thing is an urban legend, nothing more. The Waxman act is mainly about pricing and guarantees that the US will always have cheap generics available. They're cheap for a reason. The brand name is the developer of the medication and has invested millions of dollars into it, clinical trials, double blind trials, it usually takes about 7 years for a new medication to reach the market. The pharmaceutical company has to recoup all the money they put into it, that is why they get a patent of 8 years. No other company can make it for them 8 years. Upon the expiration of the patent any pharmaceutical company can manufacture and market it. Since they didn't put millions of dollars into research and developing the medication generics can be sold much cheaper than the brand name.

Re: Xan (# 12)
What is it about the Dava ones you prefer? One of the main reasons I take my Xanax is for insomnia and sleep anxiety; NEITHER of which the Dava brand really used to help me with. As a matter of fact, when I was given the opportunity to side-by-side compare the drowsiness between the Dava and the Sandoz, and the Sandoz were EXPONENTIALLY more sedating ??. That being said, Greenstone is still the best, and always will be as the only Authorized Generic.

Re: Verwon (# 1)
False, the 10% thing is an urban myth. Many lifesaving medications are made generically too, chemo meds, antibiotics, aids meds, etc.... if that was true people would be dieing. Waxman act is about pricing. What you hear is not always true. Thank you

Re: Dawn (# 2)
The Greenstone Generic is what's known as an "Authorized Generic", meaning it's formula is IDENTICAL to the brand name drug, it just comes in a generic bottle. This is because Greenstone Llc. is the subsidiary of Pfizer, the producers of Xanax, and as such are "Authorized" by Pfizer to make their Generic Identical to the Brand-Named drug at SIGNIFICANTLY LESS COST.
