About chlordiazepoxide
Art des Medikaments | A benzodiazepine |
Verwendet für | Anxiety; alcohol withdrawal |
Auch genannt | Librium® |
Verfügbar als | Kapseln |
Chlordiazepoxide works by affecting the way certain substances in your brain (called neurotransmitters) pass messages to your brain cells. It has a calming effect on various functions of your brain. The calming effect is helpful in people with anxiety, so chlordiazepoxide is sometimes prescribed to ease anxiety. If you have been prescribed it for this reason, you will be prescribed it for a very short period of time.
Chlordiazepoxide also has a muscle-relaxing effect. It is used to help relieve the symptoms of alcohol withdrawal. When you are alcohol-dependent, your body becomes used to lots of alcohol. This means that your body starts to develop withdrawal symptoms 3-8 hours after your last drink, as the effect of the alcohol wears off. So, even if you want to stop drinking, it is often difficult because of the withdrawal symptoms. Detoxification, or 'detox', involves taking a short course of a medicine which helps to prevent withdrawal symptoms when you stop drinking alcohol. The most commonly used medicine for this is chlordiazepoxide.
Before taking chlordiazepoxide
Zurück zum InhaltSome medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking chlordiazepoxide it is important that your doctor knows:
Wenn Sie schwanger sind oder stillen.
If you have any breathing problems - for example, if you have a problem where you stop breathing for short periods at night (a condition called sleep apnoea).
Wenn Sie Probleme mit der Funktion Ihrer Leber haben oder wenn Sie Probleme mit der Funktion Ihrer Nieren haben.
If you have a mental health problem. This includes conditions such as psychosis, depression, obsessive conditions, phobias and personality disorders.
If you have ever had a drug or alcohol addiction and you are not being prescribed chlordiazepoxide for this reason.
If you have a condition causing muscle weakness, such as myasthenia gravis.
If you have any problems that affect your balance or co-ordination, or affect your ability to walk.
Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.
Wenn Sie andere Medikamente einnehmen. Dazu gehören auch Medikamente, die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

How to take chlordiazepoxide
Zurück zum InhaltBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about chlordiazepoxide, and it will also provide you with a full list of the side-effects which you could experience from taking it.
Your doctor will tell you what dose of chlordiazepoxide to take, and how often to take it. The directions will also be printed on the label of the pack to remind you about what was said to you. Take your doses exactly as your doctor tells you to. As a guide:
If you are taking chlordiazepoxide for anxiety, you will probably be prescribed one capsule to take three times a day.
If you are taking it to prevent alcohol withdrawal symptoms, it is usual to take four doses a day. You will be prescribed a high dose on the first day you stop drinking, then your dose will gradually reduce over the next 5-10 days.
You can take chlordiazepoxide either with or without food.
If you forget to take a dose, take it when you remember. If when you remember, it is almost time to take your next dose, leave out the missed dose and take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.
Das Beste aus Ihrer Behandlung herausholen
Zurück zum InhaltRemember to keep any regular appointments with your doctor or clinic. This is so your doctor can check on your progress.
Chlordiazepoxide is likely to affect your reactions and ability to drive. It is an offence to drive while your reactions are impaired. Do not drive until you know how you react, especially when you first start treatment. Please also be aware that the effects of chlordiazepoxide can last into the following day. Even if your driving ability is not impaired, should you drive, you are advised to carry with you some evidence that the medicine has been prescribed for you - a repeat prescription form or a patient information leaflet from the pack is generally considered suitable.
Chlordiazepoxide is taken for short periods of time only, often for just a few days. This is because taking it for longer can lead to you feeling dependent on it. Also, your body gets used to it quickly, and after this time it is unlikely to have the same effect.
If you are going through detox, you will have agreed not to drink any alcohol. Even if you are not taking chlordiazepoxide for this reason, you should still not drink alcohol. It will increase the risk of you experiencing unwanted effects.
Your doctor could recommend that you reduce your dose of chlordiazepoxide gradually when it is time to stop taking it. This is to reduce the risk of you experiencing withdrawal effects. Follow carefully any instructions your doctor gives to you.
Chlordiazepoxide can harm an unborn child so you must avoid getting pregnant or fathering a child while you are taking it. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. You must use effective contraception during treatment and for seven months afterwards for women or four months afterwards for men. If you want to have a family, discuss this with your doctor so that you can be given advice from a specialist.
If you are due to have an operation or any dental treatment, please tell the person carrying out the treatment that you are taking chlordiazepoxide. This is because chlordiazepoxide increases the effects of some anaesthetics.
After detox, it is thought that you are less likely to go back to drinking heavily if you have counselling to help you to stay off alcohol. Your doctor, practice nurse, or local drug and alcohol unit can provide ongoing support when you are trying to stay off alcohol. Self-help groups such as Alcoholics Anonymous have also helped many people.
