Hi welcome to HCM.Valproic acid can be effective against many types of seizures common in children.Children under 2 or 3 years of age who take valproic acid have a much higher risk of liver failure than adults or older children. The first signs of it are vomiting, loss of appetite, sluggishness, and perhaps loss of seizure control, yellow skin and eyes, or swelling.To reduce side effects, the doctor probably will prescribe a low dose of valproic acid to start and will increase it slowly. Children usually start with a dose of 5 to 10 milligrams (mg) for each kilogram of their body weight per day. This is usually given in one to three equal doses per day.Valproic acid syrup is an easy way to give a valproate medicine to small children who cannot swallow capsules. The medicine is absorbed by the body a bit more quickly than when capsules are used, but the amount absorbed is the same. Your child should not stop taking valproic acid without talking to his/her healthcare provider, especially if your child has taken it for a long time. call your child doctor if child experiencing weakness facial swelling skin rash easy bruising or tiny purple-colored spots unusual bleeding unexplained fever severe abdominal pain loss of seizure control severe vomiting dark urine, or jaundice (yellowing of skin or eyes).
