What is dylar medication?

Dylar is not a medication that exists. It does not have any known uses, benefits, side effects, or interactions since it is a fictional drug. It was featured in the novel "White Noise" by Don DeLillo as an experimental pharmaceutical drug with unknown effects. Dylar's purpose and qualities are left intentionally vague in the novel, as it symbolizes the fear of death and our attempts to control and escape it through artificial means.
