Take before meals or with milk.
If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses. Contact your pharmacist if you are not sure what to do.

Theophylline 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. This permits a greater volume of air to enter the lungs and reduces the effort required to breathe.

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 theophylline 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 theophylline 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 theophylline's stimulatory effects on the central nervous system (enhanced sleeplessness, agitation, uncomfortable heart beat).
Drug Interactions: Due to potentially serious interactions, it is important to inform your doctor and pharmacist of all the other medications (prescription and over-the-counter) you are taking, no matter how insignificant they may seem.
