Dropped isopropyl alcohol pad into bottle of whiskey by mistake–still safe?

I was using a isopropyl alcohol 70% wipe to clean the inside of the neck of a bottle of Balcones Baby Blue and accidentally dropped the wipe in.

Within 15sec I poured the whole bottle into a spare empty cup and retrieved the wipe from the empty bottle and funneled it back into the bottle.

I’ve been told rubbing alcohol has methinol in it, and this can be super bad for you to consume. Is there any risk to me having the rest of the bottle? It was about 80% full and it was a single wipe.
