How Long Does Benzo Withdrawal Last?
What is the Withdrawal Time for Benzos?
Most benzo withdrawal symptoms start within 24 hours and can last from a few days to several months, depending on the length of the abuse and the strength of the benzo used. Prolonged withdrawal isn’t uncommon, however. About 10 percent of people who abuse benzos still feel withdrawal symptoms years after they have stopped taking the drugs.
There is no specific timeline dictating exactly how long withdrawal from a benzo, or benzodiazepine, medication will last.
While each individual may experience withdrawal differently, certain estimations can be made. Benzodiazepine withdrawal duration and intensity depend on several factors, including:
- Length of time taking benzodiazepines
- Dosage amount
- Type of drug used/abused
- Method used to take or abuse benzodiazepines
- Underlying medical or mental health issues
- Abuse of other drugs or alcohol concurrently
- Family history and/or previous drug or alcohol dependency
Benzodiazepines are Schedule IV controlled substances per the Drug Enforcement Administration (DEA). They are sedatives and tranquilizers prescribed to treat symptoms of insomnia, anxiety, panic, seizure disorders, and muscle tensions or spasms. Common benzodiazepines include Xanax (alprazolam), Klonopin (clonazepam), Restoril (temazepam), Ativan (lorazepam), and Valium (diazepam). Alprazolam, the generic name for Xanax, was the 13th most prescribed medication in the country in 2012, according to a survey done by IMS Health.
These medications are regularly taken recreationally, or abused for nonmedical purposes, in addition to being taken as legitimate prescriptions.
Onset of Withdrawal
Benzodiazepines are not intended to be taken long-term, as prolonged use or abuse can cause the brain to become both physically and psychologically dependent on them.
Withdrawal symptoms, ranging from a return of uncomfortable psychological symptoms to physical manifestations such as nausea and diarrhea, may occur when the drugs are removed from the bloodstream. Family history of drug dependency or previous issues with substance abuse and/or dependency may increase the likelihood of developing a dependency on a benzodiazepine and may potentially add to the withdrawal timeline duration as well.
Some short-acting benzodiazepines, like Xanax, are thought to be more potent than some of the longer-acting ones, such as Valium, as well. While withdrawal will be similar for both, users of short-acting benzos may experience withdrawal symptoms sooner and with more intensity, as benzos with longer half-lives will stay in the body longer, therefore slowing the onset of withdrawal.Benzodiazepines are all designed as central nervous system depressants; however, they each may work slightly differently at targeting certain symptoms. For example, Restoril, Dalmane (flurazepam), and Halcion (triazolam) are considered primarily hypnotic benzodiazepines prescribed for insomnia, while Xanax, Ativan, Librium (chlordiazepoxide), and Valium are classified as anxiolytics used to treat anxiety symptoms. Klonopin is considered primarily an anticonvulsant. Different metabolites of these medications make them slightly different, which may also affect how quickly they leave the bloodstream. Withdrawal from different benzodiazepines is generally thought to bring the same general symptoms; however, it is possible that an individual withdrawing from a hypnotic may have more disrupted sleep patterns while withdrawal from an anxiolytic may include higher levels of anxiety.
The method of ingestion is also related to the onset of withdrawal. For instance, snorting or injecting benzos sends the drugs straight into the bloodstream to take almost instant effect. Ingesting a pill requires that it be digested through the digestive tract, which can potentially extend the withdrawal period.
Benzodiazepines are also regularly abused in conjunction with other drugs and/or alcohol. This is called poly-drug abuse and can influence the withdrawal severity and timeline. The Treatment Episode Data Set (TEDS) report of 2011 published that 95 percent of those admitted to a drug treatment center for benzodiazepine abuse or dependency also abused another drug or alcohol simultaneously. Abuse of other illicit substances may also increase the type and number of withdrawal symptoms that occur.
Stopping a benzo “cold turkey” without medical assistance is not recommended. Instead, medical detox is required for all benzodiazepine addictions. Medical detox generally involves tapering off the drugs with professional care and support. In addition to ensuring that patients remain safe throughout the detox process, medical personnel can also help to alleviate uncomfortable withdrawal symptoms. In some cases, medical detox will involve substitute a longer-acting benzodiazepine for a shorter-acting one during the tapering process, to make withdrawal smoother and reduce withdrawal symptoms. Other medications may be prescribed during medical detox to treat specific symptoms as well. The British Journal of Clinical Pharmacology published that medications such as flumazenil may be effective during medical detox, for example. Research is ongoing to find new and improved treatment methods to ease benzodiazepine withdrawal.
Benzodiazepine withdrawal may occur in three main phases: early withdrawal, acute withdrawal, and protracted withdrawal.
The early withdrawal phase usually starts within a few hours to a few days of stopping the medication and may last a few days. During early withdrawal, an individual may experience a return of anxiety and insomnia symptoms as the brain rebounds without the drugs. Symptoms the benzos worked to suppress may come flooding back. The tapering process frequently used in medical detox may help dampen this rebound effect.
After a few days of stopping a benzodiazepine, acute withdrawal may begin. This phase constitutes the bulk of withdrawal. Symptoms may include anxiety, panic, insomnia, muscle spasms or tension, nausea and/or vomiting, diarrhea, blurred vision, seizures, hallucinations, short-term memory impairment, trouble concentrating, clouded thinking, mood swings, agitation, drug cravings, twitching and weight loss due to a decreased appetite. It is during this phase that specific medications may be most beneficial at targeting some of the certain symptoms. Suicidal thoughts and actions may occur during acute withdrawal from a benzodiazepine as well, and therapy and support groups may help diffuse these complicated emotions. Acute withdrawal may last between two weeks and several months.
Some people, around 10 percent according to a study published by ABC News, may experience protracted withdrawal syndrome that can extend several months or even years after stopping use of a benzodiazepine.
