This is a group of medications called minor tranquilizers that are used to treat anxiety, muscle spasm, insomnia, and in some cases pain. The most common and familiar names in this classification include Valium, Xanax, Tranxene, Ativan, and many others. These are potent medications and can be used very effectively in the appropriate setting, however, like all medications they are not without certain inherent risks and side effects. They can cause drowsiness and are known to cause depression or make existing depression worse. They are habit-forming, if not addicting, and therefore need to be used with caution. When used as a sleeping aid, it is said that the quality of sleep induced is not as restful as the sleep obtained without these medications. Long-term usage is to be avoided as much as possible.
