In some cases, taking Xanax can increase anxiety, especially if it is taken in large doses or for an extended period. Xanax works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA), which can have a calming effect on the brain and nervous system.
However, if Xanax is taken too frequently or for too long, the body can become dependent on it. In this case, when the drug is stopped or reduced, withdrawal symptoms, including anxiety, can occur. Additionally, taking Xanax can also cause paradoxical reactions, which are the opposite of the intended effect and include increased anxiety, irritability, or agitation.
