Free Narcan Resources

I was wondering if anyone knew of places that will give out free Narcan. I have a father with the beginning stages of dementia, and he has on several occasions forgotten that he has already taken his opioid medication, and accidentally took a second/third/fourth dose. We've started pre-labeling/sorting his medications to try to prevent it moving forward, but I'd like to have it on hand in case something like this happens again.

Any resources would be appreciated.
