The shells are hard on disposal blades and the membranes can wrap around the grinding apparatus. Once ground, the tiny bits of shell can compound other blockages. Better to compost than toss out.

While there’s no real danger to your drain or pipes per se, the addition of pharmaceuticals into the water is no good for humans or animals. There are programs that let you dispose of unused medicine properly and safely, otherwise they’re best to go into the trash, sealed.
