Safety Information

Pay attention to two agents manufactured by AstraZeneca: Dexlansoprazole (Kapidex), a new formulation of the proton-pump inhibitor lansoprazole, and bicalutamide (Casodex), which is used in combination with a hormone treatment for prostate cancer, have had medication mixups. The agent names look alike and sound alike when written and verbalized. Both written and verbal prescriptions have been dispensed in error. Bicalutamide is available as 50-mg tablets; dexlansoprazole is available as 30-mg and 60-mg capsules. TH
