Yes, Xanax withdrawal can cause dizziness. Dizziness is a common symptom of Xanax withdrawal and is often due to the effects that Xanax has on the central nervous system. When a person takes Xanax for an extended period of time, their body becomes accustomed to the presence of the drug and may start to rely on it to function normally. If a person suddenly stops taking Xanax or reduces their dose too quickly, it can cause withdrawal symptoms, including dizziness. It is important to seek medical help when discontinuing Xanax, as the withdrawal symptoms can be severe and dangerous if not managed properly.
