It is particularly important that you follow instructions in giving medicines like antibiotics, because they must work consistently over a set period of time to kill off germs such as bacteria. Often medicines like an antibiotic will be prescribed multiple times a day for about 10 days. Skipping doses or just stopping the medicine when a child's symptoms go away may do more harm than good. A child may have to start all over on the medicine or may build up an immunity to the antibiotics. Carefully listen to and read instructions about medicines because they may have special requirements, like taking them on an empty stomach or a full stomach or with water.
Some medicines even react to certain foods.
Side effects can even be a problem with children. Certain cough syrups can make them lethargic or even hyper. Consult your doctor or pharmacist if you have any questions or problems. And remember that your child's size and age are both important in giving doses of medicine. Your child's first visit to the doctor probably came before you even left the hospital.
