When children and adults are sick and suffering from nausea, sucking slowly on the frozen Ice Blocks makes it easier to rehydrate. One advantage of Hydralyte IceBlocks is that children think of them more as a frozen treat rather than a medicine. Hydralyte Electrolyte Ice Blocks are suitable for the entire family, including babies, pregnant and breastfeeding mothers. TIP: Offer Hydralyte frozen electrolyte ice blocks to children when they are sweaty on hot days (rather than a sugary icy pole). Hydralyte may be taken on the first signs of fluid loss due to vomiting and diarrhoea. Hydralyte may also be taken to help manage dehydration due to the loss of fluids through heavy sweating. This can be caused by a hot or dry environment, fever or strenuous exercise. Hydralyte is suitable for the whole family and is available in all leading pharmacies in Australia and New Zealand.
