What Instillagel does

Instillagel is used when putting a tube or instrument into a body cavity. It contains a local anaesthetic to prevent pain and antiseptics to reduce the risk of infection. It also provides lubrication to ease this process.

Before Instillagel is used

Tell the person preparing to use the gel if any of the following applies to you:

Do not use Instillagel:-

  • If you are allergic (hypersensitive) to lidocaine, chlorhexidine, methyl hydroxybenzoate, propyl hydrobenzonate or any of other ingredients of Instillagel
  • If the moist lining of the application site is damaged or bleeding

Care should be taken when using Instillagel:-

  • If you have heart problems 
  • If you have liver problems
  • If you are epileptic

Pregnancy and breast feeding

Tell the person preparing to use the gel if you are pregnant or think you might be pregnant. You can continue to breast-feed.

After using the gel

You may feel drowsy after using InstilIagel, if so do not drive or use machinery.
If the gel has been used orally (inserted into your mouth), care should be taken when chewing or swallowing as you may bite yourself without realising.

How Instillagel is used

The gel is available in two sizes - 6ml and 11ml. Usually the complete contents of the size suitable for the procedure will be used. The syringe is removed from its sterile package by tearing off the backing paper. Before removing the blue cap from the end of the syringe, free the plunger by gently pressing it. Remove the cap. Insert the nozzle into the opening of the area to be anaesthetised and press the plunger slowly to push out the gel. The anaesthetic takes about 5 minutes to work after the gel has been used.

Has the gel any side effects?

You might feel a slight stinging just after the gel is used, but this stops as soon as the anaesthetic starts to work. Most people find that there are no problems after the gel has been used but there may be a slight soreness when the effect of the local anaesthetic has worn off. If you feel that you have had any reaction to the gel, please tell your doctor as soon as possible.

Storage of the gel

The gel should not be used after the expiry date shown on the package. Instillagel does not require any special storage conditions.

The syringe is for single use only. If the complete contents are not used, the syringe and remaining gel must be thrown away.

As with all medicines, keep Instillagel away from children.
