3. How to use Citanest
[Always use this medicine exactly as your doctor or nurse has told you. Check with your doctor or nurse if you are not sure. Citanest will be given to you by a doctor.

|Use in children and adolescents
Citanest is not recommended for use in children under 6 months old.
If you use more Citanest than you should
[Serious side effects from getting too much Citanest need special treatment and the doctor treating you is trained to deal with these situations. The first signs of being given |too much Citanest are usually as follows:
• Feeling dizzy or light-headed.
I* Numbness of the lips and around the mouth.
'• Hearing problems.
I* Problems with your sight (vision). I
To reduce the risk of serious side effects, your doctor will stop giving you Citanest as [soon as these signs appear. This means that if any of these happen to you, or you
think you have received too much Citanest, tell your doctor immediately. l _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ j
