For children under 12 years, consult your healthcare professional for advice. Always read and follow the directions for use. If symptoms persist, consult your health professional. Before using laxatives, drink plenty of water and increase your fibre intake. If you are pregnant or breastfeeding, consult your healthcare professional before taking laxatives.
