About this NDC listing & data coverage
This is a bulk ingredient listing — not a retail prescription package
Theophylline 1 g/g POWDER is listed with FDA as a bulk ingredient (a drug substance supplied for further manufacturing or licensed pharmacy compounding). It is not a finished product a patient would receive at a retail pharmacy, so consumer-style information — a patient label, retail pricing, package photos — generally does not exist for this NDC. The listing identifies the substance and package for supply-chain and regulatory purposes.
