What happens to a Mouse that eats 2 pills of Valtrex 250mg and 1 Viagra ? Should i waste money on a mouse trap?

I have a mouse in the house under my kitchen sink but i suppose he got through the drawer into the junk drawer we have here with random things in it like envelopes, Scissors, Pill box with some of the valtrex i stole from my dad. There was rat poop n pee everywhere he even gnawed on some candles we had in there. Well im wondering if i should even go buy a mouse trap for him.... Whats your input?
