Temazepam is a benzodiazepine used for the short-term treatment of insomnia- a sleep disorder. Temazepam can help insomnia but may cause sedation, falls, dependence and other adverse effects even when taken as prescribed. Physical dependence is different from addiction.
Temazepam is known as Restoril which is the brand name of the drug and it is classified as a Schedule-IV drug in the United States which means that the sales of Temazepam are monitored and it is available through a legitimate prescription and one cannot get hold of Temazepam over-the-counter due to risk of abuse that can lead to addiction and life-threatening overdose.
Temazepam starts its action within 30 minutes of its administration and it takes 45 minutes to an hour to achieve peak plasma concentration. The effect of Temazepam lasts for 7 to 8 hours therefore it is advised to take the drug right before going to bed and only when you can take a good 7 to 8 hours of sleep because of inability to take a night of proper sleep and working under the influence of Temazepam can cause amnesia of the performed task.
Temazepam can cause activities such as cooking, making phone calls or driving while not fully awake, with no memory afterward. These complex sleep behaviors can occur at prescribed doses. Contact the prescriber immediately if this happens. Do not drive or operate dangerous machinery while drowsy or impaired.
Yes, one can overdose on Temazepam as this drug has a high potential for overdose when used inappropriately. Temazepam abuse imposes the risk of dependence, addiction, and overdose. Since Temazepam (Restoril) is a central nervous system depressant it slows and depresses the activity of the central nervous system by acting on the GABA receptors thus interfering with the action of GABA- inhibitory neurotransmitter which blocks the conduction of nerve impulses and reduces neuronal excitability. This brings about the sedative and relaxing effect attributed to Temazepam which is the reason it is classified as a hypnotic medicine and is used for the treatment of insomnia.
Prescribed Restoril can still cause sedation, falls, memory problems, complex sleep behaviors and physical dependence, so benefits and risks need monitoring. However, once individuals start using the drug in increased doses or for a duration longer than prescribed, they are at risk of developing an overdose. Moreover, individuals who use Restoril for recreational purposes to achieve a high associated with its use are at a greater risk to develop the life-threatening complication of Restoril overdose.
Temazepam overdose is likely higher when this drug is used concomitantly with other central nervous system depressants such as other benzodiazepines, alcohol, and opioids to enhance the euphoric effect of Temazepam. This combination synergizes the depressive effect of the different CNS depressants and results in detrimental consequences since the respiratory system, the cardiovascular system is all negatively influenced after such a combination takes place and causes breathing problems, oversedation, coma, and even death. According to the National Institute on Drug Health, every 1 in 3 opioid overdose cases involves benzodiazepine which reflects the surge in the combined use of Temazepam a benzodiazepine with an opioid.
Some individuals also frequently use stimulants like methamphetamine and cocaine to stimulate their central nervous system along with a depressant such as Temazepam so that both the drugs can counter the unpleasant effects of one another since they work through opposite mechanisms. However, such a combination proves to be deadly and not beneficial as the individuals presume because the body masks the intoxicating effects of both these drugs, and the individual keeps on taking increased doses of Temazepam which inevitably results in an overdose.
Temazepam overdose is a medical emergency and prompt medical care should be provided to the individual affected. This condition should not be overlooked and ignored since most signs of Temazepam overdose resemble alcohol intoxication even though alcohol overdose can be life-threatening as well.
Overdose symptoms can develop at different times. Seek poison-service or urgent medical advice immediately after a possible overdose, even without symptoms; call emergency services for breathing problems, seizure, collapse or inability to wake. It is vital to know about the symptoms of Temazepam overdose. Some of the signs associated with Temazepam overdose include physical as well as psychological symptoms. These include:
- Confusion
- Dizziness
- Drowsiness
- Difficulty breathing
- Loss of consciousness
- Poor reflexes
- Hypotension- Low blood pressure
- Lightheadedness
- Fainting
- Seizures
- Panic Attacks
- Extreme sleepiness
When an overdose involves increased doses of Restoril only, the symptoms of the overdose are those of central nervous system depression presenting as impaired balance and coordination, impaired short-term memory, and slurring of speech. Some individuals experiencing Temazepam overdose might face extreme anxiety, depression, agitation, hallucination, delirium, and fluctuation in their mood.
Individuals may experience hypothermia, bradycardia, hypotension, cardiac arrest, and coma in case of severe Restoril overdose since high levels of Restoril significantly depresses the central nervous system and can cause death. However, when Restoril overdose is a result of the concomitant use of Restoril and other central nervous system depressants such as opioid analgesics then the results are very deadly. Findings in such a case of Restoril overdose include slowed heart rate and labored breathing, loss of consciousness, vomiting, bluish discoloration of fingernails and lips.
A suspected temazepam overdose requires urgent medical assessment, especially with marked drowsiness, confusion, breathing problems, loss of consciousness or co-ingestion of alcohol, opioids or other sedatives. Treatment is mainly supportive. Flumazenil may be considered by clinicians in selected situations, but it is not routinely appropriate for every overdose because it can precipitate seizures or withdrawal in some patients; it does not “remove” temazepam from the body.
There is no human “fatal dose” that can be used to decide whether an ingestion is safe. Animal LD50 values are not appropriate for estimating a lethal human dose and should not guide self-triage. Risk depends on the amount and formulation, age and health, tolerance, and especially other substances such as opioids or alcohol. If an overdose is possible, contact emergency or poison services rather than waiting for a particular dose or symptom threshold.
Alcohol is a central nervous system depressant and a commonly abused drug. Temazepam (Restoril) is a prescription drug used to treat insomnia and is also a central nervous system depressant. Often people mix the two substances to achieve increased sedation and euphoria for recreational purposes. Some may do so unintentionally when they take a sleeping pill and take a drink over it, oblivious to the potential of abuse and the serious side effects that may ensue.
Since both Temazepam and Alcohol act by depressing the central nervous system it is not wise to mix the two due to increased chances of a fatal overdose. Both substances act on the GABA neurotransmitter which is the main inhibitory neurotransmitter in the brain and is known to produce a calming and sedative effect by slowing down the activity of the central nervous system.
When Restoril and Alcohol are used together the amount of the drug required to cause an overdose for both the substance decreases such that an overdose can occur at a lower dose and often result in deleterious consequences. In a seven-year study conducted by the Drug Abuse Warning Network (DAWN), 27,000 emergency room visits were attributed to using alcohol and benzodiazepines together. It was also revealed that when an overdose involved alcohol and benzodiazepine as in the case of mixing Temazepam and Alcohol, 38% of cases had unfavorable outcomes.
Hence, it is advised to not mix Temazepam and alcohol since they both act on the GABA receptors in the brain, depressing the central nervous system, and a combined effect of the two leads to heightened impairment of the CNS along with depression of the respiratory centers.
There are great dangers associated with the concomitant use of Temazepam and Alcohol. Most of the side effects that result after mixing the two substances are due to central nervous system impairment. Individuals who use both substances together will have hampered memory, poor decision-making ability, impaired judgment, and loss of coordination.
Individuals who mix alcohol and Temazepam are at the greatest risk of abusing these drugs a condition referred to as ‘polydrug abuse. Consequently, they become subjected to the unpleasant side effects that result after mixing Temazepam and Alcohol.
Alcohol increases the risk of complex sleep behaviors with Restoril, including driving, cooking or making phone calls while not fully awake and later having no memory of them. Avoid alcohol during treatment and contact the prescriber immediately if such behavior occurs.
Moreover, drinking Alcohol and Restoril can increase drowsiness, and can lead to extreme sedation, and lightheadedness. Using alcohol and Temazepam increases the risk of falls and injuries, and the risk is maximum while operating heavy machinery or driving. In addition, alcohol, and Temazepam cause nausea and vomiting. This combination is also known to worsen depression in individuals with preexisting mental health issues.
Temazepam is prescribed for short-term insomnia, usually 7 to 10 days under the US Restoril label. Follow the individual prescribed dose and schedule. Older adults need particular caution; do not extend treatment or stop suddenly without prescriber advice.
Temazepam is a benzodiazepine hypnotic that enhances the effect of GABA-A receptor signaling and can reduce the time needed to fall asleep in the short term. Insomnia is not diagnosed as a simple “chemical imbalance,” and persistent sleep problems can have multiple medical, psychological, behavioral and medication-related causes that may need assessment.
Tolerance and physical dependence may develop with repeated temazepam use, including prescribed use. Their timing and severity vary. A reduced effect should prompt prescriber review, not self-directed dose increases.
Tolerance means a reduced response after repeated use. Physical dependence means adaptation that can cause withdrawal after a rapid reduction or stopping; neither alone establishes addiction.
Temazepam Addiction Treatment and Therapies
Withdrawal symptoms can indicate physical dependence, which can occur even when a benzodiazepine has been taken exactly as prescribed. Physical dependence does not automatically mean addiction. Addiction is assessed from a broader pattern such as impaired control, compulsive use and continued use despite harm.
Withdrawal reflects the nervous system adapting after dose reduction or stopping. It should not be explained as a proven drop in an individual’s GABA level.
Withdrawal symptoms vary in onset and duration; some persist beyond six weeks. They can occur without misuse or addiction and require an individualized clinical plan.
There is no reliable universal temazepam-withdrawal timeline. Abrupt discontinuation or overly rapid dose reduction can cause serious withdrawal reactions, including seizures. The FDA advises an individualized gradual taper with ongoing monitoring; symptoms can begin at different times and may last longer in some people.
- Symptoms may include anxiety, insomnia, tremor, sweating, nausea, irritability and perceptual changes.
- Seizures, severe confusion, psychosis, marked agitation or suicidal thoughts require urgent assessment.
- The onset, peak and duration vary with dose, duration of use, other medicines and substances, health conditions and the rate of dose reduction.
- A taper should be adjusted if withdrawal symptoms become difficult to tolerate rather than forced to follow fixed calendar dates.
Temazepam withdrawal symptoms are similar to benzodiazepine withdrawal. These withdrawal episodes are very painful for the individual physically as well as psychologically and it becomes very difficult to continue normal routine tasks without taking the drug.
The symptoms of Temazepam withdrawal include:
- Headaches
- Confusion
- Irritability
- Sleeping problems
- Convulsion
- Trembling
- Abdominal pain
- Muscle cramps
- Panic attacks
- Palpitations
- Psychosis
- Nausea
- Vomiting
- Anxiety
- Nightmares
- Depression
- Hallucinations
- Crying spells
- Suicidal ideations
- Extreme fatigue
- Rebound Insomnia
The appropriate level of care depends on clinical risk. Many people can reduce a prescribed benzodiazepine with outpatient prescriber support, while hospital or residential care may be appropriate for severe withdrawal risk, repeated complications, unstable mental health or complex substance use. Treatment is about safely reducing the dose and addressing the underlying sleep or mental-health problem, not simply “clearing” the medicine from the body.
