Hematocrit, hemoglobin, potassium, white blood cells: decreased values

Patient monitoring

• Monitor kidney and liver function test results and serum lipid levels.
☞ Watch for signs and symptoms of adverse reactions, especially bleeding tendency and hypersensitivity reaction.
• Monitor periodic blood counts during first year of therapy.
• Check CK level if myopathy occurs.

Patient teaching

• Tell patient to take drug 30 minutes before breakfast and dinner.
☞ Advise patient to immediately report signs or symptoms of anaphylaxis (such as difficulty breathing or rash) or other allergic reactions.
☞ Instruct patient to immediately report unusual bleeding or bruising or muscle pain.
• Caution patient to avoid driving and other hazardous activities until he knows how drug affects concentration and alertness.
• Stress importance of diet and exercise in lowering lipid levels.
• Inform patient that he'll undergo regular blood testing during therapy.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs and tests mentioned above.
