If you suspect that you are experiencing unwanted effects with your oxtriphylline, report them to your pharmacist.
Oxtriphylline is a bronchodilator that works by relaxing smooth muscles in the bronchial tubes (air passages to the lungs) to allow air to move in and out of the lungs more easily.
When starting this medication, it may take a few weeks for your physician to find the dose that is right for you. The doctor may draw some blood to help him/her determine how much oxtriphylline is in your body and then adjust your dose if there is too much or too little. The dose can vary quite significantly from person to person, even if they are the same sex, height and weight. It is very important that the correct oxtriphylline blood level be reached as inappropriate levels may result in serious unwanted effects.
Eating or drinking large quantities of products that are high in caffeine (chocolate, tea, coffee, soft drinks) can further increase oxtriphylline's stimulatory effects on the central nervous system (e.g. enhanced sleeplessness, agitation, uncomfortable heart beat).
