Answer is 5%

Codeine is narcotic analgesic and is also the cough suppressant. It is available in the form of salts as either codeine sulfate or phosphate. It is naturally obtained from opium, and is also semi-synthetically synthesized for the pharmaceutical use.

The maximum dose of codeine sulfate that the adult can take safely is 120 mg per day.
