Hello, When did you give it ? How 's he acting now? This medicine's for adults!!
You gave 4-fold the adult dose of a cough suppressant called dextromathorphan that can have sedating (making sleepy) side effects. You must take your son to ER if he is too sleepy or acts "out of it". PLEASE keep medicines out of his reach.
It is for children an adults according to my family docotor who reccomended it for my son. It also says this on the bottle. I mistakenly read the dose table for children incorrectly.
I gave him the dose of 10 mL about 9:15 PM and he was asleep around 10:30 PM. He was already tired before I gave it to him and he seemed normal when he feel asleep. I called posion control and they infrormed me that the dose is not lethel for his weight ( 36 pounds ) but to watch for the following signs. .
Vomting, Acting out of the normal or in a daze. They also informed me not to let him sleep on his back in case he vomits. The also informed my that If I didn't feel comfortable to take him to the er. I don't feel comfortable but I don't want to scare him by waking him up and taking him to the er. Posion control also suggested that I tickle his feet and see if he wakes up over the next couple of hours.
You could counter drowsiness with weak sweet coffee or black tea with sugar and lemon etc given every now and then, by rousing him and making him sit up.
The effect of this type is variable from person to person. He needs observation by an adult constantly for a day after the high dose.
