Pharmacists are urging the government to heed international warnings banning children from using Bonjela - a remedy for mouth ulcers and infant teething - after fears were raised that it could lead to a deadly brain and liver condition. British health watchdogs have banned distribution of the gel after an ingredient was found to increase the risk of Reye's syndrome. William Chui Chun-ming, education director of the Society of Hospital Pharmacists, said: 'We noticed this problem two years ago, but had no evidence or international backing to support it.' A Health Department spokesman said no urgent action would be taken. Iris Chang, president of the Practising Pharmacists Association, said: 'We have advised all community pharmacists that products containing salicylate salts should not be recommended to individuals below 16.' Bonjela Teething Gel is safe as it does not contain the salts.
