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.

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.
