Consumer:

Using liothyronine together with aminophylline may alter the effects of aminophylline. When liothyronine is started, stopped, or changed you should be monitored for an altered response to your aminophylline medication. Contact your doctor if you experience a worsening of breathing symptoms, or any signs of aminophylline toxicity including nausea, vomiting, diarrhea, headache, restlessness, insomnia, or irregular heartbeats. If your doctor does prescribe these medications together, you may need a dose adjustment or special tests to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

MONITOR: The metabolism of theophylline is directly related to thyroid function. Theophylline clearance is decreased in hypothyroid patients and increased in hyperthyroid patients. Toxicity or subtherapeutic levels may occur. Similar interactions may occur with other methylxanthines.

MANAGEMENT: When thyroid hormone dosage is instituted, discontinued, or changed, close observation for altered theophylline effect and serum concentrations is recommended. Patients should be advised to notify their physician if they experience a worsening of their respiratory symptoms, or any signs of theophylline toxicity including nausea, vomiting, diarrhea, headache, restlessness, insomnia, or irregular heartbeats.
