Your doctor may prescribe medicines, e. g tranquillizers, that may help to relieve some short-term stress-related anxieties. However, they shouldn't be taken for long periods because of the risk of addiction. For this reason they aren't usually prescribed. Antidepressants can treat certain anxiety disorders such as GAD, social phobia, OCD and anxiety associated with depression. Beta-blockers relieve many of the physical symptoms of anxiety such as palpitations and shaking, and may be helpful for some people. They don't affect psychological symptoms, but some people find they can relax more if their physical symptoms are relieved. Always ask your doctor for advice and read the patient information leaflet that comes with your medicine.
