» Technetium Tc 99m Succimer Injection is a sterile, clear, colorless, aqueous solution of succimer complexed with ^99mTc. It is suitable for intravenous administration. It contains not less than 85.0 percent of the labeled amount of ^99mTc as the succimer complex expressed in megabecquerels (microcuries or millicuries) per mL at the time indicated in the labeling. It may contain reducing agents. Other chemical forms of radioactivity do not exceed 15.0 percent of the total radioactivity.
