A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Using isoniazid together with oxtriphylline can increase the effects of oxtriphylline. You should contact your doctor if you experience nausea, vomiting, diarrhea, headache, restlessness, insomnia, seizures, or an irregular heartbeat. You may need a dose adjustment or special test 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: Theophylline serum concentrations may be gradually increased by concomitant isoniazid administration. The mechanism is thought to involve isoniazid-induced inhibition of the CYP450 3A4 and 1A2 hepatic metabolism of theophylline.

MANAGEMENT: Clinical monitoring of patient response and tolerance and serum theophylline levels is recommended when isoniazid is added. Patients should be advised to report any signs of theophylline toxicity to their caregiver, including nausea, vomiting, diarrhea, headache, restlessness, insomnia, or irregular heartbeat.
