What Should I Do If I Miss a Dose?

If you do not take your theophylline as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose. Try to take your theophylline dosage on schedule, as even small variations in how you take the drug can cause serious side effects.
