It can be given orally orally, with or without food, and can be prescribed alone or in combination with other medicines. The medication may cause mild side effects like nausea, vomiting, dry mouth, dizziness, sleepiness, and headache. It is important to inform the doctor of any medical history, including heart, liver, kidney, or birth problems, to avoid complications and better plan the child's treatment.
