Specific withdrawal symptoms that may appear in an individual addicted to or dependent on sedatives include:
- Restlessness
- An anxious mental state
- Diarrhea
- Abdominal cramping
- Nausea
- Vomiting
- Convulsions (i.e., seizures)
- Appetite loss
- Disturbed sleep
- Sleeplessness
- Sensory hallucinations
- Muscle tremors or weakness
- Body temperature elevation
- Blood pressure elevation
- Heart rate elevation
Additional problems found in cases where addiction is also present include an inability to set limits on the amount of barbiturate or benzodiazepine consumed on a given day, and an inability to set limits on how often medication consumption occurs on a given day.
Whether related to barbiturate use or benzodiazepine use, sedative addiction forms part of a larger condition known as sedative, hypnotic, or anxiolytic use disorder. This condition, as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), also includes symptoms of non-addicted sedative abuse that are prominent enough to interfere with the ability to lead a functional life. These symptoms can include such things as:
- Establishment of sedative use as a top priority in daily life
- An unwillingness to stop taking sedatives even when intake leads to obvious problems in close, personal interactions
- Recurring use of a barbiturate or benzodiazepine in situations where this use poses a significant physical risk to self or others
In any given person, sedative, hypnotic, or anxiolytic use disorder may exclusively include symptoms of addiction or exclusively include symptoms of abuse. However, the condition’s inclusive definition was established because many affected individuals experience combined symptoms of abuse and addiction.
