Benzodiazepines: Purposes, Classifications, Consequences, and Perils
================================================================================
Benzodiazepines are a class of drugs commonly used to treat conditions such as anxiety, insomnia, seizure disorders, and panic disorder. Examples of benzodiazepines and their uses include alprazolam (Xanax) for panic and anxiety disorders, clonazepam (Klonopin) for panic disorder and seizure disorders, diazepam (Valium) for panic attacks, seizures, insomnia, and alcohol withdrawal, lorazepam (Ativan) for anxiety, seizures, and anesthesia, and temazepam (Restoril) for insomnia [1].
However, misuse of these drugs can lead to potentially life-threatening problems. To ensure safe use, people should only take benzodiazepines if a doctor prescribes them, tell the doctor about any medications or other substances, including supplements, that they are taking, follow the doctor's instructions precisely, avoid using the drugs for longer than the doctor prescribes, ask the doctor before changing the dosage, refrain from using them alongside alcohol or opioids, refrain from using another person's drugs, keep all drugs out of the reach of children, and consider asking the doctor about alternative options [2].
The side effects of benzodiazepine use may include drowsiness, confusion, dizziness, impaired coordination, depression, increased anxiety, memory problems, behavioral changes, delirium (especially in older people), risk of dependence (especially with long-term use), and possibly an increased risk of dementia (although this is not certain) [1].
When a person decides to stop using benzodiazepines, withdrawal symptoms may occur. Common withdrawal symptoms include both physical and psychological effects. Physically, people often experience muscle pain and stiffness, headaches, nausea, vomiting, digestive problems, tremors, sleep disturbances (such as insomnia and vivid dreams), fatigue, dizziness, appetite changes, increased heart rate, sweating, and chills. Psychologically, withdrawal can cause heightened anxiety, panic attacks, irritability, mood swings, depression, intrusive thoughts, difficulty concentrating, memory problems, depersonalization, and derealization (feeling detached from self or surroundings) [1][3].
Withdrawal symptoms typically begin within 24 hours of cessation and may last from a few days to several months, depending on factors like the specific benzodiazepine used and duration of use. Short-acting benzodiazepines tend to cause more intense and rapid-onset withdrawal symptoms compared to long-acting ones, which have a slower withdrawal profile [2].
More severe withdrawal symptoms can include hallucinations, seizures, restless legs syndrome, and suicidal ideation, although these are less common and require medical attention [3][4].
Effective management of benzodiazepine withdrawal generally involves gradual tapering, medical support, symptomatic treatment, psychological support, close monitoring, and a carefully tailored plan developed with healthcare professionals to ensure safety and improve comfort during detoxification [3][4].
Before starting treatment with benzodiazepines, a person must tell their doctor about every other medication that they are using, as some drugs may intensify the effects of benzodiazepines, while others may make them less effective. It is essential to follow the doctor's instructions for stopping the use of benzodiazepines to prevent unwanted effects. It is not recommended to use benzodiazepines for more than 2 weeks [2].
A benzodiazepine overdose can lead to extreme sedation or drowsiness, a very low breathing rate, confusion and difficulty thinking, slurred speech, loss of muscle control, a coma, and can be fatal if a person uses the drugs with alcohol or opioids, is older and takes too much of the drug, or is taking other drugs and the effects build up in their body [2].
Benzodiazepines can help treat some mental health and neurological conditions, but it is essential to use them with care. A person should always tell their doctor about any other drugs that they are using and seek medical help at once if any unexpected reactions occur.
- In some cases, prolonged use of benzodiazepines can lead to an increased risk of developing dementia, though this is not definitive.
- Alongside anxiety and insomnia, benzodiazepines may also be used to manage conditions like psoriatic arthritis and multiple sclerosis.
- A predictive study showed a correlation between HIV and an increased risk of hepatitis B and C co-infections among people living with HIV.
- Obesity and type 2 diabetes can significantly increase a person's risk of developing atopic dermatitis, a type of eczema.
- In the context of health-and-wellness and mental-health, the misuse of opioids has been linked to anxiety and depression.
- Recent research has suggested a potential role for biologic treatments in the management of both psoriatic arthritis and ankylosing spondylitis.
- A q-tip should never be inserted into the ear, as it can lead to infections like swimmer's ear (otitis externa) or even more serious complications like infectious anthrax or mastoiditis.
- Ulcerative colitis, a type of inflammatory bowel disease, can sometimes increase the risk of colorectal cancer.
- Cancer can contribute to depression, anxiety, and a decrease in overall health-and-wellness.
- Breast cancer is one of the most commonly diagnosed types of cancer in women, and it is crucial to maintain regular screenings to increase early detection and survival rates.
- Management of withdrawal symptoms from benzodiazepines may involve treatments for depression, anxiety, and sleep disorders that arise during the detoxification process.
- Effective health-and-wellness and mental-health management often involves a balanced approach, taking into account factors like diet, exercise, stress management, and preventative care for various conditions.
- Science continues to explore the potential connections between certain conditions, such as the link between obesity and atopic dermatitis, and the underlying mechanisms involved in developing these diseases.
