Xanax is approved by The Food and Drug Administration to treat certain kinds of anxiety, including generalized anxiety disorder (GAD). It can treat various symptoms of GAD, including high levels of anxiety, restlessness, and muscle tension. Xanax is a central nervous system (CNS) depressant. It is in the benzodiazepine class of medications, which comprises drugs that slow down the CNS.
Xanax works by increasing the effects of a brain chemical called gamma-aminobutyric acid (GABA), which promotes calmness and produces a relaxed feeling. The drug decreases the level of excitement in the brain to treat anxiety and panic disorders. The United States government has classified benzodiazepines, including alprazolam, as Schedule IV controlled substances in the Controlled Substances Act because of their abuse potential. This classification makes it easier for the government to track the prescription and distribution of Xanax.
People may experience the following effects from Xanax, as well as from other depressant drugs:
- anxiety relief
- easing of muscle tension
- relief from insomnia
People may notice that Xanax affects the mind. It can cause a temporary loss of memory, feelings of hostility and irritability, and disturbing or vivid dreams.
If someone takes too much Xanax, they may experience:
- shallow breathing
- clammy skin
- dilated pupils
- a weak and rapid heartbeat
- coma or death, in cases of overdose
White Xanax vs Green Xanax
Green Xanax : Green pills are similar in strength to White and Yellow Xanax bars and typically contain 2 mg of the drug. The effects of the green pills are, therefore, the same as those seen with yellow and white Xanax bars. Green pills are available in rectangular, oval, triangular, and round shapes, usually in doses of 2 mg to 3 mg. In the oval shape, they are known as green football Xanax with a strength of 1 mg. Other street names include green oval Xanax and green monster Xanax. Hulk Xanax is a slow-release form with lower sedation effects. The triangular green pills have a strength of 3 mg and this is the strongest dose available. In general, the green pills are considered stronger than the white ones. The price of green Xanax bars on the street varies according to demand and supply, but typically one bar costs about $6. The company called Par Pharmaceuticals distributes pale green Xanax bars. These 2-mg rectangular pills are different in that they have the imprint “S 90 3” and have two scores (instead of three)
White Xanax : these are Rectangular Bars that contain 2 mg of active alprazolam. It is important to note that the maximum dose of alprazolam is 4 mg per day, so white Xanax bars of 2 mg is a very high dose of the drug. This form of the drug produces strong sedation within minutes of being consumed. The bar is typically marked with scores or grooves to make it easy for the user to split into smaller portions. The bar shape of alprazolam in any color (white, yellow, or green) usually contains a 2-mg dose. Because white Xanax bars have such a high strength, it is not advisable to quit them cold turkey because this can produce severe and dangerous withdrawal symptoms. Each manufacturer puts their own unique imprint on the bars (for example, G 372 2 or X ANA X 2). White pills are also available in round, rectangular, oval, and triangular shapes with strength varying from 0.25 mg to 2 mg.
How long does 2mg Xanax last?
In comparison with other benzodiazepines, the body absorbs Xanax quickly, so its effects come on rapidly. Within about 1–2 hours, the concentration of Xanax in the blood reaches its peak. The effects of the drug usually appear within 1 hour, with one small scale study finding an average onset time of 49 minutes with oral administration. Xanax also leaves the body quickly. Its half-life is 11.2 hours in healthy adults, meaning that the body removes about half of the Xanax that it has absorbed in just over 11 hours. Doctors often prescribe Xanax to take three times per day, spread out over the course of the day. SEE: Difference Between White and Green Xanax
