Entrophen® 81 mg has a special enteric coating to help prevent stomach irritation.

The special enteric coating of Entrophen 81 mg tablets allows them to pass intact through the stomach and on into the intestine before they dissolve which may reduce the risk of stomach irritation.


Adults: 1 to 4 tablets daily as directed by a physician. Tablets must be swallowed whole, not crushed, broken or chewed, in order to protect the enteric coating. Do not exceed the dosage recommended by your doctor.
