• Monitor for desired effect.
• Watch for GI upset, adverse CNS effects (such as headache and drowsiness), and hypersensitivity reaction.
• Stay alert for GI bleeding and ulcers, especially in long-term therapy.
• In long-term therapy, assess renal and hepatic function regularly.
• Monitor blood pressure closely during treatment.
• Tell patient to take oral drug with full glass of water, with food, or after meals to minimize GI upset.
• To help prevent esophageal irritation, instruct patient to avoid lying down for 30 to 60 minutes after taking dose.
☞ Instruct patient to immediately report irregular heartbeats, black tarry stools, vision changes, unusual tiredness, yellowing of skin or eyes, change in urination pattern, difficulty breathing, finger or ankle swelling, weight gain, itching, rash, fever, or sore throat.
• Caution patient to avoid driving and other hazardous activities until he knows how drug affects concentration, alertness, and balance.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, herbs, and behaviors mentioned above.
