Bongela overdose 🙈

Is it possible to overdose on bongela? My little ones teething and is suffering really bad, today has been the worst. On a normal day he has half an ashton parsons powder in the morn, bongela throughout the day and then the other half of the powder at night. Sometimes if hes unsettled he will have calpol before bed aswellm however it states not to use bongela continuously and not to give before 3 hour doses. Is it possible to give too much bongela as today he had it before the 3 hours???
