Hydefrizene

Hydefrizene (high-deaf-ruh-zeen) is a red pill that is used to alleviate pain. In smaller cases, such as headaches, the pain goes away in a maximum of 30 minutes; in greater cases, such as broken bones, it essentially acts as an anesthetic, removing lesser pains and dulling the larger ones.

It, along with Zepehydrine, was used by the Doctor in Azumanga Who and was in a Pill Box with eighteen other kinds of pills. They also appeared during the conception of A Poor Man's Christmas.
