Symptoms intensify as the dose increases. Feelings of jitteriness and excitability often become evident as the effects of large doses wear off. Overdose Very high doses of benzodiazepines can cause unconsciousness or coma. Death rarely occurs from overdose of benzodiazepines alone, but some deaths have occurred when large doses were combined with alcohol or other drugs. Deaths have occurred from the inhalation of mucus or vomit when a person has been unconscious.
Benzodiazepines can help to relieve anxiety in the short term.
But they do not solve the problem that caused the anxiety in the first place. They treat the symptoms but not the cause. Very high doses of benzodiazepines over a long period of time may cause confusion, lack of coordination, depression and slurred speech and may lead to increased aggressiveness. It is ironic that the long-term effects include anxiety and sleeplessness when these are the very problems that benzodiazepines are supposed to relieve. Bingeing In the case of benzodiazopines a 'binge' is where benzodiazepines are not taken on a daily basis but a whole pack is taken in one session.
