The needles come with the pen with a prescription. If you need more you can get them at the pharmacy. I got a prescription but they are on Amazon. To be honest I don't bother with the disposal container but that comes with your first pen.

The needle disposal container should come with the pen. However, each state has different rules about disposal. Here in Illinois I have to take my full container to the police station for disposal and they also have the empty red container available
