•    Iglu Gel is a treatment for fast, effective relief of pain from common mouth ulcers, sore gums and denture rubbing.

•    The product, which at first looks like a pale yellow paste, forms a smooth, flexible and adhesive protective gel coating when it becomes wet on contact with saliva inside the mouth.

•    Iglu Gel is suitable for use by adults, the elderly and children over 7 years of age.

•    The product works in three ways:

•    by forming a gel coating to protect the sensitive and delicate area of the mouth lining as it heals, and

•    by the actions of its two active ingredients, lidocaine hydrochloride and aminoacridine hydrochloride, which work by:

•    stopping pain (lidocaine hydrochloride is a local anaesthetic), and

•    preventing infection (aminoacridine hydrochloride is an antiseptic).


Do not use Iglu Gel if you are allergic (hypersensitive) to lidocaine hydrochloride, aminoacridine hydrochloride or any of the other ingredients of Iglu Gel listed in Section 6.

Take special care when using this product:

•    Apply it sparingly.

•    Keep the product away from your eyes.

Using other medicines

Iglu Gel is not known to affect, or to be affected by, any other medicines.

Pregnancy and breast-feeding

It is unclear whether this product is safe for use during pregnancy and breast-feeding. The potential risks are unknown. If in doubt, ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machinery

Using this product is not known to affect your ability to drive or use machinery.


Only use Iglu Gel for localised application inside the mouth for the conditions it is recommended for.

For adults, the elderly and children over 7 years of age:

•    Wash your hands before and after use.

•    If you are treating several ulcers, repeat

steps 1 to 3 below for each one:

1.    Use a clean tissue to gently remove excess moisture/saliva from the ulcer area.

2.    Squeeze a small quantity of Iglu onto a clean, dry finger tip or cotton bud, and then apply it directly to the ulcer using a single, gentle wiping action (avoid dabbing).

3.    At first, the product may seem quite pasty and sticky, but after contact with saliva, the product will form a flexible and adhesive gel coating over and around the ulcer area.

•    Re-apply the gel, following steps 1 to 3 above, as necessary for each ulcer. The aim is to keep the ulcer area(s) protected with a coating of gel. As a guide, each application should normally last for an hour or more, although, on occasions, eating or drinking may make it necessary to re-apply the gel. In some cases, Iglu may remain in place for several hours, as it has strong adhesive properties.

•    Do not apply excessive amounts of the gel, and avoid applying gel to the back of the tongue and throat area.

•    If you are treating sores caused by rubbing from false teeth/dentures etc, avoid using Iglu at the same time (e.g. use the gel at night or when not wearing dentures).

If the gel accidentally gets into the eyes

it may cause irritation. If it gets into the eyes, rinse immediately with plenty of water and continue rinsing for 10 to 15 minutes, holding the eyelids well apart. If rinsing one eye, take care to avoid washing product into the other eye.

If irritation persists, contact a doctor.

If you use too much Iglu Gel overdosage of the active ingredients is unlikely to occur because of the low concentrations used and the small pack size. Overdose may make swallowing difficult due to the loss of feeling. This may increase the risk of food or drink going down the wrong way. Generalised numbness of the mouth may also lead to biting the inside of your mouth when eating.

Excessive overdose may also lead to generalised side effects. If you experience any of the following, seek urgent medical attention; nervousness, drowsiness, breathing problems or low blood pressure.

If you occasionally forget to use Iglu Gel

do not worry, just carry on using it when you remember.

If you have any further questions on the use of this product, ask your doctor, dentist or pharmacist.


Like all medicines, Iglu Gel can cause side effects, although not everybody gets them.

On rare occasions, hypersensitivity reactions to lidocaine hydrochloride and aminoacridine hydrochloride can occur, involving wheezing or shortness of breath. Seek urgent medical attention if you experience these symptoms.

If you experience any other symptoms not mentioned in this leaflet, stop using the product and tell your doctor, dentist or pharmacist.

Overdose can also lead to other side effects (see section above: If you use too much Iglu Gel).

If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet.

You can also report side effects directly via the Yellow Card Scheme at: uk/yellowcard. By reporting side effects you can help provide more information on the safety of this medicine.
