Antianxiety Medications for Sleep

Anti-anxiety drugs, sometimes known as tranquilizers, work by slowing down the central nervous system, creating a sense of relaxation and calmness. The most common class of these medications are the benzodiazepines. Included, among others, are Xanax, Valium, and Ativan, any of which might be prescribed for anxiety, a muscle relaxant, or as sleeping pills.

Xanax

• Xanax works by binding to receptors in the brain, causing a feeling of relaxation and drowsiness, which is why physicians often prescribe it to patients having trouble sleeping. If you take more than 4 mg of Xanax daily, you are at risk of becoming physically or mentally dependent, and might experience severe withdrawal symptoms if you stop or lower the dosage.

Valium

• While Valium has long been associated with treating anxiety disorders and seizures, its symptoms of sleepiness and tiredness have made it a go-to prescription for sleeping disorders also. Valium is a strong drug that should not be stopped suddenly. Watch for interactions with other medications -- tell your doctor everything else you are taking. Also be wary of driving while under the influence of Valium, and take care to limit alcohol consumption.

Ativan

• This is another benzodiasepine normally prescribed for anxiety relief but can be used as a sleep aid as well. As with the previous two drugs mentioned, Ativan should be used with care, following your doctor's exact instructions. Ativan can be habit forming and absolutely should not be taken with alcohol, as it increases the effect. Take special care to inform your doctor if you are pregnant or if you become pregnant while taking Ativan. Classified as a pregnancy category D drug, Ativan can cause birth defects.

Additional Side Effects

• Keep a sharp eye peeled for side effects. Your doctor should review the possibilities of adverse reactions with you but, if that has not happened, read the entire warning label that comes with the prescription. According to the Physician's Desk Reference, some side effects to be wary of are excessive sedation, dizziness, weakness, unsteadiness, fatigue, amnesia, and dose-dependent respiratory dependency. This is not an exhaustive list. Other side effects might not be anticipated. If you notice a symptom that increases in intensity or duration, it would be a good idea to contact your doctor. With strong drugs like these, erring on the side of caution is preferred.
