Hypersensitivity to lidocaine hydrochloride and/or cetylpyridinium chloride or to any of the excipients listed in section 6.1.

4.4 Special warnings and precautions for use

Do not use more than one product containing lidocaine at the same time.

The recommended dose should not be exceeded. Keep out of the sight and reach of children.

This medicine contains 29.4mg sorbitol in each 0.2g (pea sized blob). The additive effect of concomitantly administered products containing sorbitol (or fructose) and dietary intake of sorbitol (or fructose) should be taken into account. The content of sorbitol in medicinal products for oral use may affect the bioavailability of other medicinal products for oral use administered concomitantly. Patients with hereditary fructose intolerance (HFI) should not take/be given this medicinal product. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

The castor oil may cause stomach upsets, diarrhoea, and skin reactions.

This medicine contains 19.42mg of alcohol (ethanol) in each 0.2g. The amount in 0.2g of this medicine is equivalent to less than 1 ml beer or 1 ml wine.

The small amount of alcohol in this medicine will not have any noticeable effects.

This medicine contains less than 1 mmol sodium (23 mg) per 0.2g, that is to say essentially 'sodium-free'.

This medicine contains 0.00019mg benzyl alcohol in each 0.2g. Benzyl alcohol may cause allergic reactions and/or mild local irritation. Advise patients to not use for more than a week in young children (less than 3 years old). There is increased risk due to accumulation in young children. High volumes should be used with caution and only if necessary, especially in subjects with liver or kidney impairment because of the risk of accumulation and toxicity (metabolic acidosis). Benzyl alcohol has been associated with serious adverse events and death in neonates (“gasping syndrome”). The minimum amount of benzyl alcohol at which toxicity may occur is not known.

This medicine contains 0.00077mg benzoic acid (E210) in each 0.2g. Benzoic acid may cause local irritation. May cause non-immunologic immediate contact reactions by a possible cholinergic mechanism. Benzoic acid may increase jaundice (yellowing of the skin and eyes) in newborn babies (up to 4 weeks old).

4.5 Interaction with other medicinal products and other forms of interaction

No drug interactions with CALGEL TEETHING GEL are known.

Drug interactions between intravenously administered lidocaine and oral procainamide, oral phenytoin alone or in combination with phenobarbital, primidone or carbamazepine, oral propanolol and non-potassium sparing diuretics including bumetanide, furosemide and thiazide have been reported. These drug effects are unlikely to be relevant to the use of CALGEL TEETHING GEL.

4.6 Fertility, pregnancy and lactation

The medicinal product is indicated for use in toddlers and infants, therefore use during pregnancy and lactation is not applicable.

4.7 Effects on ability to drive and use machines

Calgel Teething Gel has no influence on the ability to drive and use machines.

4.8 Undesirable effects

When used according to instructions side effects would not be expected. However, isolated cases of hypersensitivity to lidocaine hydrochloride have been reported in adults and in a child over 12 years following local injection. Hypersensitivity presented in these cases as localised oedema with slight difficulty in breathing or as generalised rash.

Chamomile, a minor ingredient in the herbal flavouring agent, has been documented as causing allergic reactions. Hypersensitivity to chamomile normally manifests as breathing difficulties in atopic individuals. Anaphylactic reactions have been reported in individuals drinking herbal tea infusions containing chamomile (herbal tea asthma). Sensitised individuals may demonstrate positive skin reactions to preparations containing chamomile.

In the event of any unwanted side effects, use should be discontinued and a doctor consulted.
