Benzodiazepine dependence and tolerance
Taking benzodiazepines regularly may not only lead to physical dependence (addiction), but can also lead to psychological dependence where people may feel they need the drug to cope with daily life.
After only a short amount of time, a person can develop a tolerance, which means they need to take larger and larger doses to achieve the same effect. Some people may begin to experience tolerance after only a few days. Over time, the body comes to depend on benzodiazepines to function.
Withdrawal from benzodiazepines
Withdrawal symptoms vary from person to person and are different depending on the type of benzodiazepine being taken.
Always withdraw from benzodiazepines slowly, over a period of time, under medical supervision.
Someone who suddenly stops taking benzodiazepines after a prolonged period of use can put themselves at risk of serious withdrawal symptoms, such as seizures.
Symptoms can last from a few weeks to a year and may include:
- aching or twitching muscles
- dizziness and tremors
- nausea, vomiting and stomach pains
- bizarre dreams, difficulty sleeping and fatigue
- poor concentration
- anxiety and irritability
- altered perception and heightening of senses
