Some of the medications that treat and help anxiety include Xanax, klonopin, Valium and Ativan, as stated by Helpguide. All of these medications are known as tranquilizers and basically work to calm and relax a person who has anxiety.
Some doctors prefer to prescribe their patients beta blockers or antidepressants instead of the tranquilizers and some patients may end up needing all three of the medications to keep their anxiety under control. These medications pose several side effects, although so it can take a while to figure out which ones work for each patient. Some of the possible side effects of these medications include confusion, nausea, blurred vision, lightheadedness, slurred speech and fatigue, as stated by Helpguide.
