• Monitor for signs and symptoms of infection, which drug may mask.
• Advise patient to take with milk, antacids, or food to minimize GI upset.
• Tell patient drug may mask signs and symptoms of infection. Instruct him to contact prescriber if he suspects he has an infection.
☞ Teach patient to recognize and immediately report signs and symptoms of allergic reaction or GI bleeding.
• Inform patient that many herbs increase the risk of GI bleeding. Caution him not to use herbs without prescriber's approval.
