Babies under 2 years of age generally do not need to take worming medication, and babies over 2 years of age can take worming medication if they have roundworms, because after all, babies are not as hygienic as adults, and they are usually exposed to more things, so they can easily come into contact with worm eggs. The intestinal wormer tablets sold in pharmacies can be given to babies over 2 years old. So how often should babies take worming medication? Parents who suspect that their babies over 2 years old need to be dewormed should first go to the hospital for a stool test to find out whether there are parasites in the body and which kind of parasites are present, and it is necessary to use the medicine under the guidance of the doctor. In general, deworming is sufficient once a year. Deworming medicine is best taken on an empty stomach or at night before going to bed, because at this time, the concentration of deworming medicine in the intestine will be higher, which can improve the effect of killing worms. Nowadays, the medicine for roundworm is usually broken up the adult worms, so you usually won’t see the whole worm pulled out, so there is no need to be nervous. If there are whole worms, it means that there are more roundworms in the child’s stomach. You can have another shot after six months. It should be noted that parents should not blindly deworm themselves, not only can the parasites increase drug resistance, making it more difficult to deworm in the future, but also may cause acute biliary roundworm disease due to improper deworming of roundworms into the bile duct. Moreover, the commonly used deworming drugs have certain toxic side effects and should not be used casually.
