Hi. My four year old son was prescribed 1.5 tspn augmentin, 2x/day for a swollen lymphnode in his throat. I gave him his first dose this morning as he was eating his breakfast, and an hour later he became nauseous and 2 hours later he vomited. Did the med absorb? Is the dose too high? I'm afraid to give it to him tonight before bed if he's going to vomit again while asleep? Is this common? Thank you.
