Clonazepam and Chlordiazepoxide in Detox

Clonazepam (brand name Klonopin) and Chlordiazepoxide (also known as Limbitrol or Librium) both belong to a group of medicines called benzodiazepines.

Both drugs are commonly used to treat alcohol withdrawal in alcohol rehab centres as part of treatment programmes.

As the medicines act like sedatives, they help alleviate many of the symptoms associated with alcohol withdrawal. Clonazepam and Chlordiazepoxide help reduce anxiety and panic, assist with sleep, lessen muscle spasms and irritable bowel syndrome (IBS), and help control seizures—some being very common when people come off alcohol.

How Do The Drugs Work?  

Both drugs are part of a group of medicines called benzodiazepines, known as sedatives or, the outdated name, tranquilisers. Other medications in this group include Zanax and Valium.

When you drink alcohol, it increases the level of a neurotransmitter called GABA in your brain. When people stop drinking, GABA levels decrease, creating unpleasant withdrawal symptoms.

Benzodiazepines target your central nervous system, slowing down your body, calming your brain and lessening the impact of withdrawal. Benzodiazepines enhance GABA receptors, passing information to the body to make it feel relaxed.

Your doctor will usually start you on a low dose and adjust to find a level that works for you over the coming weeks. You’ll likely split the medication throughout the day or take it in one larger dose.

Help With Alcohol Withdrawal

Patients are often prescribed benzodiazepines (nicknamed ‘benzos’) when they have a supervised alcohol detox at a registered alcohol rehab clinic. If you choose to stay at a clinic as an inpatient, you’ll live there for a few weeks to three months. Benzodiazepines are usually prescribed for up to three days during detox. After your detox, they could be issued in a lower dose for anything up to six weeks.

As an outpatient, you can receive addiction treatment at home or at venues to suit you. Outpatient treatment serves those who have work or family commitments or a mild addiction. In cases of mild addiction, you can detox at home in combination with regular checks ins with your addiction specialist.

Alcohol withdrawal is a challenging process, and it can produce unpleasant mental and physical sensations.

Some alcoholics have been chronic drinkers for over 20 years, whilst others have had a short term but intense addiction. If the body consumes regular and excessive amounts of alcohol, it reacts when alcohol is taken away. Mental health tends to plummet during a detox, as the brain relies on alcohol to help lessen anxiety, depression, anger, or other mental health conditions. When you remove the prop of alcohol, many people need the temporary help of Clonazepam or Chlordiazepoxide.

You will experience side effects when you complete alcohol detox, and the severity depends on the level of your addiction. Possible impacts on your body and mind include feeling sick and vomiting, uncontrolled movements of the body, increased heart rate, convulsions, hallucinations, anxiety, depression and tiredness.

Are Clonazepam And Chlordiazepoxide Addictive?

Both these medications are addictive, so doctors usually prescribe them for a short amount of time, from two to four weeks, six weeks being the maximum. Your doctor will gradually reduce your dose so your body gets used to being without the medicines.

Tell your doctor right away if you feel that you’re becoming addicted to Clonazepam or Chlordiazepoxide. They may prescribe alternative medicines or a lower dose.

Call 111 or visit the NHS 111 website if you suspect you’ve taken too much. Your symptoms could include feeling overstimulated, weak muscles, irregular or slow heartbeat, unusual eye movement, difficulty speaking and feeling very sleepy.

Can Anyone Take Them?

Talk through your medical history with your doctor or alcohol before taking Clonazepam or Chlordiazepoxide, as they aren’t suitable for everyone. Your doctor will suggest alternative medications that will work for you. Make sure you inform your specialist if you:

-have a muscle weakness called myasthenia gravis

-experience sleep apnoea (breathing problem when you sleep)

-suffer from depression or suicidal thoughts

-have been diagnosed with a personality disorder

-have kidney, liver or lung conditions

-are pregnant, trying for a baby or breastfeeding

-have had allergic reactions to medicines in the past

Clonazepam And Chlordiazepoxide are only legally available through prescription.

Are There Any Side Effects?

Most people report feeling sleepy throughout the day. Don’t drive or operate heavy machinery if you’re taking these medicines. It’s important not to drink any alcohol when taking Clonazepam and Chlordiazepoxide, as you’ll likely go into a deep sleep and find it hard to rouse yourself. In some extreme cases, combining Benzodiazepines with alcohol can lead to death, so make it a priority to avoid alcohol.

  • How long are rehab programmes typically?

    This will largely depend on whether you opt for an outpatient or inpatient addiction treatment programme. Most of the inpatient treatment programmes that we may refer you to will likely be 28 day courses. However, there are some inpatient treatments that can last for a series of months. Largely, the length of time that you require actual therapy sessions to treat your addiction will be dependent upon how severe your addiction is, how committed you are to recovery, and how well you respond to treatment.
  • Can addiction be cured?

    This is a question which can bring up a lot of debate over the nature of chronic illnesses and what technically qualifies as being “cured.” What should be stressed is that an addiction can be treated and you can learn how to manage your addiction for the rest of your life. Addiction is a chronic illness, so the threat of relapse will always be present. However, that is not something to be concerned about as such, rather you will learn through intensive treatment how to avoid relapse and recognise the signs of a potential relapse earlier so as to better avoid it.
  • Is rehab expensive?

    There are many options when it comes to rehab and so the cost varies. If you are wanting to access a premium private inpatient rehab, then the cost will be a lot more than going on an outpatient basis. Outpatient rehab costs less as you are accessing fewer facilities (private room, food) and can be an option for those with a mild dependence on drugs and/or alcohol. The NHS provides free options but there is usually a long waiting list, and the quality of care might not match that of a private facility.
