Types of Xanax Bars
Xanax pills come in diverse formulations, identifying their strength, manufacturer, and release mechanism. The standard 'Xanax Bar' is a rectangular pill containing 2 mg of alprazolam. The most common color variants include: White bars (generic alprazolam, scored into 4 sections); Yellow bars (often nicknamed 'schoolbuses', containing 2 mg, manufactured by Actavis); Green bars (nicknamed 'hulks', 2 mg, manufactured by Dava Pharmaceuticals); and Blue bars (oval shape or scored 2 mg tablets, manufactured by Breckenridge). Understanding these distinctions ensures patients receive accurate dosages and avoid uncertified counterfeits.

Frequently Asked Clinical Questions
Do different colored Xanax bars have different strengths?
Most rectangular Xanax bars (white, yellow, and green) contain exactly 2mg of alprazolam. The color differences are due to pharmaceutical dyes used by different FDA-approved generic manufacturers (Actavis, Dava, Pfizer).
How can I tell if a Xanax pill is authentic?
Authentic tablets have clean edges, crisp imprint stamps (e.g., '039', 'S 90 3', 'XANAX 2'), consistent color saturation, and are sealed in official blister or pharmacy containers with batch lot tracking.
