Anxiety Disorders Medicine Medications can ease anxiety symptoms. SSRIs (including celexa lexapro, paxil and lexapro), SNRRIs (including Cymbalta and fluoxetine) and antihistamines, such as Vistaril are usually prescribed. Diazepam for instance is a benzodiazepine, for instance. These medications are prescribed only for a short time because they can be addictive.
