Benzodiazepine Drugs: Risks and Safer Alternatives
Benzodiazepines, commonly known as benzos, are a class of psychoactive drugs that are prescribed to treat conditions like anxiety, insomnia, and depression. While they can provide relief for many, benzodiazepines also carry some serious risks that patients need to be aware of. In this article, we will take a closer look at benzodiazepines, analyze some of their risks, and discuss safer alternatives for treating common mental health conditions.
What are Benzodiazepines?
Benzodiazepines work by enhancing the effect of the neurotransmitter GABA, which has a calming effect in the brain. Some common benzodiazepines prescribed include diazepam (Valium), alprazolam (Xanax), clonazepam (Klonopin), and lorazepam (Ativan). They are often prescribed as "as needed" for acute symptoms but may also be taken daily for conditions like generalized anxiety disorder.
While benzodiazepines can provide quick relief from symptoms like severe anxiety or insomnia, regular use carries risks of both physical and psychological dependence. The brain can adapt to their constant presence, requiring higher doses to achieve the same effect over time. This makes it difficult and dangerous to discontinue use abruptly.
Risk of Dependence and Withdrawal
One of the biggest concerns with long-term benzodiazepine use is developing a physical and psychological dependence on the drug. According to the National Institute on Drug Abuse, up to one-third of patients prescribed benzodiazepines for longer than a month will experience some degree of misuse. The risk of dependence rises the longer someone takes them.
Stopping benzodiazepines after regular use can also produce severe and sometimes life-threatening withdrawal symptoms. These may include anxiety, panic attacks, insomnia, tremors, delusions, seizures, and in rare cases psychosis or death. Withdrawal symptoms are one of the main reasons it is unsafe to stop taking benzodiazepines cold turkey without a doctor's supervision and a slow taper plan. The likelihood of dependence and withdrawal are major factors patients need to consider before starting long-term benzodiazepine treatment.
Risk of Falls, Injuries and Car Accidents
Among the elderly patient population in particular, benzodiazepines carry an increased risk of falls, fractures, and injuries. According to a study in the British Medical Journal, seniors who use benzodiazepines have a 30-50% higher risk of hip fractures compared to non-users. They may cause side effects like dizziness, lack of coordination and impaired cognition that increase fall risk.
Benzodiazepines are also associated with a heightened risk of car accidents. A meta-analysis in the Traffic Injury Prevention journal found motor vehicle accidents double in risk for those who have recently filled a benzodiazepine prescription compared to non-users. Their sedating effects can impair driving ability, slow reaction times and increase risk-taking behaviors behind the wheel.
Interactions with Other Substances
Benzodiazepines can interact dangerously with other prescription medications, over-the-counter products, herbs and supplements as well as alcohol and illicit drugs. Combining benzodiazepines with opioids substantially increases the risk of potentially fatal respiratory depression. Mixing them with alcohol is especially risky and can be lethal in high doses due to additive sedating effects on the central nervous system. It is critical patients inform all of their healthcare providers about all substances they are consuming to minimize interaction risks.
Safer Alternatives for Managing Common Conditions
Given the very real risks of dependence, withdrawal and adverse effects, it is worth exploring alternative treatment options for conditions commonly treated with benzodiazepines like anxiety, insomnia and depression. Cognitive behavioral therapy (CBT) has been shown to be as or more effective than benzodiazepines for conditions like generalized anxiety disorder when used in the long-term without risk of addiction or side effects.
For insomnia, tried and true lifestyle modifications like establishing a regular sleep schedule, avoiding screens before bed, reducing caffeine and limiting daytime naps can help increase natural sleep drive. Under a doctor's guidance, herbal supplements like valerian root, chamomile or melatonin may provide relaxation and sleep support with fewer risks than prescription drugs.
Anti-depressants targeting serotonin and norepinephrine like SSRIs (Prozac, Lexapro) can effectively treat both depression and anxiety in many cases. Although they do carry some risks of side effects as well, the likelihood of developing dependence is much lower than benzodiazepines when taken as prescribed.
The Bottom Line
In summary, while benzodiazepines have their place in acute or short-term treatment of severe symptoms, their inherent risks of dependence, withdrawal and adverse effects make them less than ideal options for managing chronic mental health conditions like anxiety and insomnia long-term. Non-drug therapies and alternative medications should be considered first whenever possible to deliver relief in a safer manner. An individual risks-benefits discussion with a medical provider is crucial for any patient prescribed or relying on benzodiazepines long-term.
