Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain and reduce fever. It is available in different forms and strengths, including tablets, capsules, and liquid suspension. According to the sources provided, the safe dosage of Advil or ibuprofen for children depends on their age, weight, and medical condition.

Children's ibuprofen is available over-the-counter and by prescription, and it is important to follow the recommended dosage instructions carefully. The maximum daily dose of ibuprofen for children is generally 40 mg/kg of body weight, divided into several doses throughout the day [2]. The recommended dose for infants and children under 12 years of age is based on their weight, with a maximum of 10 mg/kg per dose and 4 doses per day [3]. It is important to use a measuring device to ensure accurate dosing and avoid overdosing [3].

However, ibuprofen should not be given to infants younger than 6 months old, except under the guidance of a healthcare provider [3]. Children with certain medical conditions, such as kidney disease, asthma, or bleeding disorders, may require a lower dose or should avoid ibuprofen altogether [2].

In summary, the safe dosage of Advil or ibuprofen for children depends on their age, weight, and medical condition. Parents and caregivers should follow the recommended dosage instructions carefully, use a measuring device, and consult a healthcare provider if they have any concerns or questions about giving ibuprofen to their child.
