Contents of the pack and other information
1. What Sialanar is and what it is used for
Sialanar is a medicine that contains the active substance glycopyrronium. Glycopyrronium belongs to a group of medicines known as quaternary ammonium anticholinergics, which are agents that block or reduce the transmission between nerve cells. This reduced transmission can de-activate the cells that produce saliva.
Sialanar is used to treat excessive production of saliva (sialorrhoea) in children and adolescents aged 3 years and older.
Sialorrhoea (drooling or excessive salivation) is a common symptom of many diseases of the nerves and muscles. It is mostly caused by poor control of muscles in the face. Acute sialorrhoea may be associated with inflammation, dental infections or infections of the mouth.
Sialanar acts on the salivary glands to reduce production of saliva.
2. What you need to know before you give Sialanar

is allergic to glycopyrronium or any of the other ingredients of this medicine (listed in section 6)
is pregnant or breast feeding − has glaucoma (raised pressure in the eye)
is unable to completely empty the bladder (urinary retention) − has severe kidney disease
has an obstruction of the stomach (pyloric stenosis) or bowel causing vomiting

abnormal blood brain barrier (the layer of cells surrounding the brain)
If you are not sure if any of the above applies to your child, talk to a doctor or pharmacist before giving Sialanar.
Avoid exposing the child to hot or very warm temperature (hot weather, high room temperature) to avoid over heating and the possibility of heat stroke. Check with the child’s doctor during hot weather to see if the dose of Sialanar should be reduced.
Reduced salivation can increase the risk of dental disease therefore the child’s teeth should be brushed daily and they should have regular dental health checks.
Children with kidney problems may be given a lower dose.
Check the child’s pulse if they seem unwell. Report a very slow or very fast heart rate to their doctor.
