Introduction
Clonidine belongs to a family of medicines called alpha-2 agonists. It has many effects on the body and can be used for a range of conditions.
In adults, clonidine is commonly prescribed to manage high blood pressure. Available information generally refers to this use, and may be less relevant for your child.
In palliative care, clonidine is used to relieve pain, dystonia, irritability, agitation, anxiety as well as symptoms related to problems of the autonomic nervous system.
Medication instructions
How to give Clonidine
Clonidine is available in different formulations such as tablets, patches (applied to your child’s skin) and injections.
Unfortunately, clonidine is not readily available as a liquid formulation. Some hospital or compounding pharmacies may be able to prepare a liquid preparation to be given via mouth or feeding tube. Our team will discuss which clonidine formulation is best for your child.
Please note, if your child uses clonidine patches, the packaging contains clonidine patches and additional nonmedicated patches to place over the clonidine patch, to keep it in place if needed.
Your child may be started on regular doses of clonidine as a “background” dosing regimen. This may be given as oral/enteral doses, a patch on the skin or as injections (either intravenous or under the skin) two to four times per day.
Additional doses can be used if required. These are often called “breakthrough” doses.
Dosing information
The dose needed is very individual. Some children need more than others.
- The correct dose is the amount that eases your child's symptoms.
- Your doctor will work out a safe starting dose, which may need to be increased or decreased.
- So that your child achieves the best possible symptom control, with the least side effects, any changes will be monitored carefully by our team.
Medication safety and storage

Clonidine may cause the following unwanted side effects.
Not everybody experiences side effects and it is important to remember these are not an allergic reaction, and are often temporary and manageable. If your child experiences any of these, please inform us.
