4.2 Posology and method of administration

Unless prescribed otherwise, for urological use: a) Catheterisation:
Instill 6 ml or 11 ml. After the usual cleansing of the glans and external urethral orifice Instillagel is slowly instilled into the urethra and the glans is compressed until the local anaesthetic and disinfectant effect has occurred.
b) Cystoscopy and endoscopy:
Instill 11 ml, and an additional 6 ml or 11 ml if necessary. The entire urethra including the external sphincter must be coated with a lubricant film and anaesthetised for germ‐free and painless introduction of instruments. A penis clamp is applied at the coronal sulcus.
c) Urethral strictures (stricture division, bouginage):
Instill 11 ml Instillagel, and an additional 6 ml or 11 ml if necessary, and apply a penis clamp.
The required urethral anaesthesia is obtained after 5 ‐ 10 minutes.
For gynaecological investigations:
Slowly instill 6 ml, and where necessary another 6 ml, into the vagina. The quantity depends on the patient's anatomic conditions and/or on the procedure to be performed. Alternatively, the gel can be dispensed and distributed as evenly as possible on the instrument to be inserted.
The full local anaesthetic and disinfectant (antiseptic) effect of Instillagel occurs after 5 to 10 minutes.

Instillagel must not be used in children under 2 years.
The maximum dose in children aged between 2 and 12 years should usually not exceed 2.9 mg lidocaine hydrochloride per kg body weight. This is equivalent to 1.5 ml Instillagel per 10 kg body weight.
The systemic absorption of lidocaine can be increased in children, so caution is warranted accordingly.
