Do not take worming medication before the age of 2. Now we all pay attention to hygiene, there is generally no parasite, so before giving children worming medication, you can first take the baby’s stool to do a laboratory test, test results have worms and then give the baby worming medication. After all, deworming medication is toxic and can cause adverse reactions in children and can impair liver function. Deworming medicine is usually taken two hours after a meal, when the stomach and intestines are basically emptied of food, and the deworming medicine is more likely to come into contact with worms and thus be effective. An hour before taking the medicine, give the child an appropriate amount of sour vinegar, which will help to expel the worms.
