Not only that anastrozole 1mg amex womens health group, they can be taken merely on an as-needed basis, when having to deal with an especially anxiety-arousing situation, such as confronting a phobia, giving a speech, or going to a job interview. The side effects tend to be less disturbing than those associated with antidepressants as well. And for 20 years or so after their introduction, they were seen as safer than barbiturates with a lower risk of overdose. They appear to work by reinforcing a substance in the brain that blocks the excitability of nerve cells. As with many addictions, withdrawal from benzodiazepines can be difficult and even danger- ous. Rebound anxiety that’s more severe than that experienced before taking the drug is possible upon withdrawal. Benzodiazepines are also associated with increasing the risk of falling among the elderly. In addition, a recent report suggested that benzodiazepines may double the risk of getting into a motor vehicle accident. That risk rapidly escalates when benzodiazepines are taken in combination with alcohol. In fact, benzodiazepines are particularly problematic for those who have a history of substance abuse. Those who are addicted to recre- ational drugs or alcohol readily become addicted to these medications and are at greater risk for combining alcohol with their medication. Prescribing benzodiazepines to those who have suffered a recent trauma seems logical and humane. And indeed, these medications have the potential to improve sleep and reduce both arousal and anxiety. Michael Otto at Massachusetts General Hospital have found that the risk of relapse is increased when these medications are com- bined with changes in thinking and behaving. In the long run, it appears that for most people, learning coping strategies to deal with their anxiety seems better than merely seeking pharmacological solutions — especially with respect to the benzodiazepines. Nevertheless, the benzodiazepines remain one of the most popular approaches to the treatment of anxiety disorders, especially among general practitioners who have no special training in psychiatry. And these medications can sometimes play an important role, especially for short-term, acute stress and anxiety, as well as for those for whom other medications haven’t helped. Following are some of the most commonly prescribed benzodiazepines listed by trade name, with generic names in parentheses: ✓ Ativan (lorazepam) ✓ Centrax (prazepam) ✓ Klonopin (clonazepam) ✓ Librium (chlordiazepoxide) ✓ Serax (oxazepam) ✓ Valium (diazepam) ✓ Xanax (alprazolam) Miscellaneous tranquilizers A few miscellaneous tranquilizers are chemically unrelated to the benzodiaz- epines and thus appear to work rather differently.
