3. How to take Chloral Hydrate Oral Solution

Always take Chloral Hydrate Oral Solution exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

For Chloral Hydrate Oral Solution to work successfully, your doctor will need to identify the most appropriate dose for treating your sleeplessness. Chloral Hydrate Oral Solution is available in two strengths (500mg/5ml and 143mg/5ml). Your doctor will help you to select the most appropriate strength and dose.

Chloral Hydrate Oral Solution should be administered as a single daily dose, 15-30 minutes before bedtime, with water or milk.

The usual recommended doses for Chloral Hydrate 143mg/5ml Oral Solution are:

Adults and Children aged 12 years and over and the Elderly:

The usual starting dose in 430-860 mg (15-30 ml of the 143mg/5ml strength).

In the frail elderly or patients with liver problems, a smaller dose may be required.

Not more than 70 ml of the 143mg/5ml strength Chloral Hydrate Oral Solution (equivalent to 2 g of Chloral Hydrate) should be taken in any one day.

Children 2 - 11 years:

The use of Chloral Hydrate Oral Solution in children and adolescents is not generally recommended and if used should be under the supervision of a medical specialist. The dose will be calculated by your doctor or pharmacist based on the weight of the child. You should follow their instructions. Not more than 35 ml of the 143mg/5ml strength Chloral Hydrate Oral Solution (equivalent to 1 g of Chloral Hydrate) should be taken in any one day.

If you are unsure about how to take your medicine, ask your doctor or pharmacist.

Duration of treatment and stopping treatment

Chloral Hydrate Oral Solution is usually prescribed for the short-term treatment of sleeping problems when other non-medication treatments (e.g. behavioural therapy and sleep hygiene) have failed, for a maximum treatment period of 2 weeks.

Repeat courses of Chloral Hydrate Oral Solution are not recommended and can only be administered following medical specialist re-assessment, because there is a risk of abuse and dependence.

If you take Chloral Hydrate Oral Solution over a long period of time, you may find that the medicine takes longer to work and the effect does not last for as long. This is called “tolerance” to the chloral hydrate ingredient. If you find you are becoming “tolerant” to Chloral Hydrate Oral Solution, do not increase the amount you take. Speak to your doctor.

Following prolonged treatment with Chloral Hydrate Oral Solution the dose should be slowly reduced before discontinuation, because there is a risk of withdrawal symptoms. Suddenly stopping Chloral Hydrate Oral Solution may cause delirium (severe confusion). Contact your doctor before you stop taking the medicine, as they will advise you how to stop.

If you take more Chloral Hydrate Oral Solution than you should

In the event of an accidental overdose, contact your nearest hospital casualty department or tell your doctor immediately. It is advisable to have the medicine in its original packaging available for the doctor or hospital. Signs of an overdose include, vomiting, breathing problems, abnormal heartbeat, abnormally low body temperature, pin point pupils, low blood pressure or coma.

If you forget to take Chloral Hydrate Oral Solution

If you have missed one dose, this dose should be omitted, and the next dose should be taken at the usual time. Do not take a double dose to make up for a forgotten dose.
