I just bought some Gravol for my kids. It's even called "Gravol for Children". It was dosage information for children 2 to under 6 years, and for children 6 to under 12 years. There is no dosage information for anybody older than 12 years old. But there is the following: CAUTION: Do not exceed the recommended dosage. MAY CAUSE DROWSINESS. AVOID DRIVING A MOTOR VEHICLE OR PERFORMING TASKS REQUIRING MENTAL ALERTNESS. Avoid alcoholic beverages. Do not take if you have: glaucoma, chronic lung disease, difficulty in urination due to an enlargment of the prostate gland, or if you are pregnant or breast-feeding unless directed by a physician. [and some other cautions not quite so inappropriate] I had to take it back - my chain smoking, alcoholic, pregnant, car driving 6 year old daughter couldn't take them.
