Lorazepam (Oral)

Lorazepam is used to treat anxiety caused by depression and for the short-term relief of anxiety.


Lorazepam is taken orally in the treatment of anxiety disorders. It can be used for the short-term relief of anxiety and can be used to relieve the symptoms of anxiety that are suffering from depression.

Lorazepam works on the brain to relieve these symptoms and is a part of the medicine group benzodiazepines. These medicines are central nervous system depressants that work to slow down the reception of the patient's nervous system. Central nervous system suppressants should never be used in conjunction with one another because the effects can be greatly increased.

Lorazepam is available only with a prescription from a doctor and is given as either a solution or a tablet.
