THEOPHYLLINE EXTENDED RELEASE.
THEOPHYLLINE is a bronchodilator, or medicine that helps to make breathing easier. It relaxes the bronchial airways, improving the flow of air through the lungs. Theophylline helps to reduce coughing, wheezing, shortness of breath, or difficulty breathing in patients with chronic (long-term) lung disorders such as asthma, bronchitis, or emphysema. Theophylline occurs naturally in teas and is chemically similar to caffeine or theobromine (found in cocoa).
THEOPHYLLINE works best when taken on an empty stomach one hour before or two hours after meals. If stomach upset occurs, it may be taken with food. Long acting capsules and tablets must be swallowed whole. Crushing or chewing them may destroy the long action and increase the possibility of side effects. If capsules are too large to swallow, open the capsule and mix the contents with jelly or applesauce and swallow without chewing. This medication works best if a constant level is maintained in the body. Do this by taking doses at evenly spaced intervals.
MISSED DOSE: If you miss a dose, take as soon as remembered do not take if it is almost time for the next dose, instead, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up.
