<bot>: Hello, Well, it can overdose. It is generally recommended to be given no more than 4 times a day total dose of 300 mg per 24 hrs.; and 2 ml is on the large size of dosing.  Funny story: my mother had an overdose of it when she 1) started taking her recommended dose 2) took erythromycin which causes it to accumulate 3) stopped cigarettes which lower its metabolism when you stop 4) had the flu which lowers the metabolism of it but 5) won a casino jackpot and hyperventilated which triggered the seizure. So, a lot of factors can influence this Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further. Take care
