Yes, a child aged 3 can take a Gravol suppository, but the dosage depends on their weight. Typically, a child under 20kg would take half of a 25mg suppository, while a child between 20 and 28kg would take a full 25mg suppository. It is important to cut the suppository lengthwise if needed. If you only have 100mg suppositories, cutting them into the correct dosage may be challenging.
