Yellow Xanax bar R039 2mg

Yellow Xanax bar R039 2mg also informally known as “zanies” or “planks.” As mentioned earlier, Xanax bars are used to treat anxiety disorders like generalized anxiety disorder and social anxiety. A single Xanax bar contains 2mg of alprazolam, but they are often broken in half for a controlled and more manageable dosing.

People who’ve been taking alprazolam medication for a long time and have developed a tolerance to regular dosing are often prescribed two-quarter-size Xanax bars. So taking the entire Xanax bar is not always ideal as it could lead to unwanted side effects like irritability, drowsiness, and chest pain.

What Does Xanax Look Like?

Xanax medications exist in several forms and colors, which indicates the drug’s concentration.

We’ve listed the most common type of Xanax pills and bars you might encounter:

White Xanax Bar

This is the most common type of Xanax bar you’ll see commercially. White Xanax pills or bars contain 2mg, which is standard for most treatment plans.

Purple Xanax Bar

Purple Xanax pills or bars contain 2mg of the product. The only difference here is that Pfizer manufactures purple Xanax.

Green Xanax Bar

Green Xanax bars contain 3mg of alprazolam, making them more potent than the 2mg white or purple pills. This is often prescribed for those with a tolerance to the standard dose.

Yellow Xanax Bar

Yellow Xanax bars, also known as “school bus” or generic alprazolam bars, contain 2mg of alprazolam. The color difference is due to the drug’s manufacturer, not its potency or concentration.

Peach Xanax Bar

A peach Xanax bar contains the lowest concentration at 0.5mg. Peach Xanax bars also come in 2 mg variations.

Blue Xanax Bar

The most common concentration of a blue Xanax bar is 1 mg, but you can also find higher concentrations.

Pink Xanax Bar

Also known as the “strongest mg Xanax bar,” a pink Xanax bar is often available at a 3mg concentration. This is rarely used and requires medical supervision.
