Theophylline: decreased sedative effect of oxazepam
Drug-diagnostic tests.Alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, lactate dehydrogenase: increased levels
Hematocrit, thyroid uptake of sodium iodide 123I and131I, white blood cells: decreased values
Drug-food.Cabbage: decreased drug blood level
Drug-herbs.Chamomile, hops, kava, valerian, skullcap: increased CNS depression
Drug-behaviors.Alcohol use: increased CNS depression
☞ Monitor liver function tests and watch for signs and symptoms of hepatitis.
• Check vital signs. Stay alert for respiratory depression, orthostatic hypotension, and tachycardia.
• Monitor neurologic status. As needed, take measures to prevent injury.
• Watch for signs and symptoms of psychological or physical dependence.
• When tapering, watch for withdrawal symptoms.
• Tell patient he may take with or without meals, but should avoid cabbage.
• Advise patient to take exactly as prescribed. Tell him drug can cause dependence, and emphasize importance of following tapering instructions to avoid withdrawal symptoms.
☞ Urge patient to immediately report unusual tiredness, nausea, appetite loss, or yellowing of skin or eyes.
• Tell patient to change position slowly to avoid blood pressure decrease.
• Instruct patient to report severe dizziness, weakness, persistent drowsiness, palpitations, or visual changes.
• Advise patient not to drink alcohol.
