... (i.e. a drop twice daily). Tonight, after a first drop landed on his eye lashes, he kicked my hand as I fought to get him still. So, when I tried to apply the drop, he shook the bottle and 2 drops went into his eye in quick succession. I've read about the warnings on Cosopt overdose in the patient leaflet and read online a bit. I remain worried. Should I watch over his sleep all night? Should he be fine? Quick replies would be much appreciated. Worried Mum. 25 August 2011, 23:52
