Cough as side effect for amoxicillin?

[Anonymous]

Our toddler has had a neverending string of colds this fall, finally escalating in an ear infection. We got prescribed amoxicillin and of course it could be coincidence but I swear his coughing increases substantially after taking it for a few hours (2x a day). Of course it could also just be all the mucus built up overnight and then he gets it first thing in the morning and would be coughing up a storm regardless. But that wouldn’t explain the after dinner dose and the hacking before bedtime? He’s not wheezing or anything but it’s like he just cannot turn off the cough reflex for an hour or two.

Now I’m wondering if it’s possibly causing a mild allergic reaction and making his throat itch or something? And that’s causing the increased coughing? It could also just be pure coincidence with the timing of his latest cold. I know I should just call the nurse line, but wondering if anyone else has experienced this. For what it’s worth, there’s a family history of penicillin allergy so I’m on heightened alert. He’s not had any typical hives/skin rash outbreaks.
