How dangerous is loratadine to dogs?

My 45 lbs. dog found a 10 mg loratadine pill still in a blister pack that someone dropped in our apartment parking lot. I managed to get it away from her before she swallowed it. However, she managed to chew through to the pill and it looks like a tiny part of the pill is missing (it could also have been crushed. She managed to mangle the package so it's hard to tell if anything is actually missing). The internet searches I did are giving me conflicting information. So far, an hour later, she's acting normal. First time pet mom is just worried.
