Aspirin used to be considered safe to cure numerous disorders, and was widely used both in its soluble and insoluble form. Today, however, it is not so well thought to be useful for the relief of headache or other pains and it will reduce a fever for 2 or 3 hours and so make a patient feel more comfortable, but except in very rare cases it will cure nothing. Furthermore, there have been some very serious cases of poisoning as a result of taking aspirin. This is why children's aspirins are not recommended, for they are often nicely flavoured, so the children are tempted to eat them like sweets. For small children suitably small quantities of ordinary adult soluble aspirin should be used after having checked the dose with the physician.
