They're great for anxiety, yeah, but someone educate me (I don't have much experience with benzos beyond abusing them): what's the point of being prescribed multiple benzos? Is one (valium) something you take in the morning to last most of the day while the other (xanax) is used for emergencies or panic attacks? If that's not it, I can't see why any doctor would put you on two different benzos.
Not many doctors like the idea of prescribing two benzodiazepines...and especially not long term. The only times that I've been prescribed two benzodiazepines (hence, from the same doctor) were when I had already been on one for several years and another hypnotic was needed for my insomnia. I've heard of people with muscle pain being prescribed two but I find that foolish. There are many muscle relaxants that can be prescribed WITH a benzodiazepine just like many different sleeping aids can be prescribed WITH a benzodiazepine.
As for the differences, they are all just anti-anxiety agents with slightly varying effects. They are also prescribed as sleep aids, usually just the hypnotics. Some people find them recreational. I don't but I find them very effective drugs for anxiety
Xanax (Alprazolam): Great for panic attacks. Immediately kicks in but short acting which makes it very addicting as a result. People who suffer panic attacks know what situations cause them extreme stress so they will take it beforehand. Other people eventually just take it every 3-4 hours always expecting panic attacks. Also very effective for phobic disorders.
Klonopin (Clonazepam): Prescribed for people who suffer panic attacks. Unlike Xanax it can be taken just twice a day to prevent unanticipated panic because it lasts anywhere from 6-12 hours. Not as effective as Xanax for extreme emergencies. Klonopin also produces great muscle relaxation as it is one of only two benzodiazepines actually (labeled) prescribed for seizure disorders. Great for social phobia.
Restoril (Temazepam): Prescribed for insomnia. Produces hypnosis
Ativan (Lorazepam): Prescribed mostly for Generalized Anxiety Disorder. Also an effective muscle relaxant.
Valium (Diazepam): Prescribed for almost every anxiety disorder. Ineffective as an anti-panic medication though. Makes me very groggy, drowsy and irritated so my opinions on this benzo are biased.
Midazolam (Versed): For surgery it is used intravenously to knock you out and produces amnesia.
...those are the basics. There are so many more. All produce the following effects just to various degrees and prescribed as: Anxiolytics (anti-anxiety/anti-panic), hypnotics, anti-seizure, amnesiacs, muscle relaxants.
I could go into extreme detail about this subject but most don't understand and those who do will completely change the pace of this thread
