Dis-Chem stock a range of deworming tablets and syrups, with options suitable for deworming children and adults. Visit your nearest store or shop online to see the range of medicines available over-the-counter. Deworming is possible with an over-the-counter treatment. Dewormers come in a liquid form for children. Adults and pets are usually given tablets to take. The medication kills off the adult worms in the digestive system but not the eggs, so it’s recommended that you repeat deworming after 6 months.
