My 26-month-old, 26-pound daughter was diagnosed as having an ear infection. Her doctor put her on amoxicillin -- 500 mg, twice a day. Everyone is telling me that 1000 mg per day is an awful lot. What do you think?
The best dose of amoxicillin has changed in recent years. The change to high-dose amoxicillin came because many bacteria were getting partially resistant to it. Rather than switching to antibiotics that are broader spectrum or with more side effects, high-dose amoxicillin is considered the most effective and safest of the first line treatments.
The recommended dosage used to be 10 to 30 mg per pound of body weight per day. But for ear infections, it is now better to give 60 to 80 mg per pound per day. For her, that would be somewhere between 750 and 1000 mg daily. The timing between doses does not need to be precise, but the farther apart the doses are, the lower the chances of diarrhea as a side effect.
Antibiotics do kill beneficial bacteria as well, and the more effective the antibiotic, the more likely this will happen. Eating yogurt with active cultures is a great way to replenish them. Some of the frozen varieties are the most affective.
