Theophylline is a breathing medicine used to manage obstructive airway diseases. Opening narrow passages, Theophylline decreases airflow resistance to assist in regular, comfortable lung function.
Theophylline belongs to a group of drugs called methylxanthines, chemically related to caffeine. It acts as the active compound in products such as Uniphyl Cr and is used to help keep the airways open.
Theophylline works mainly as a bronchodilator, relaxing the muscles around the breathing tubes to make it easier for air to move in and out of the lungs, easing tightness and wheezing.
Theophylline is commonly used to manage asthma symptoms that are not fully controlled by other inhaled medicines. It also helps people with chronic obstructive pulmonary disease (COPD) breathe more comfortably during everyday tasks. In some cases, theophylline reduces breathing problems after certain surgeries. Older adults who have trouble using inhalers may benefit from a tablet form. It can also be part of a plan to prevent nighttime breathing difficulties for certain lung conditions.
After a tablet is swallowed, theophylline is absorbed into the bloodstream and travels to the lungs. It relaxes the smooth muscle surrounding the airways, allowing more air to flow through.
The drug also mildly stimulates the breathing center in the brain, supporting deeper breaths. This dual action improves overall airflow and reduces the effort needed to breathe.
Pregnant, planning a pregnancy, or breastfeeding individuals should discuss theophylline with a healthcare professional, as it can cross the placenta and enter breast milk. People with heart rhythm problems, uncontrolled seizures, or liver disease should use this medicine with caution. Individuals sensitive to caffeine may notice stronger side effects, as theophylline belongs to the same chemical family.
Theophylline can interact with alcohol, certain antibiotics, and medicines that affect heart rhythm. It may also be influenced by foods high in caffeine, such as coffee, tea, or chocolate. Always check the label of the specific product you receive for a complete list of possible interactions.
Older adults and people with liver impairment often process theophylline more slowly, so side effects may appear more frequently. Those who consume large amounts of caffeine or take interacting medications are also at higher risk for experiencing unwanted effects.
Keep your theophylline tablets in a dry place away from direct sunlight and out of reach of children. Store them at room temperature unless the label advises refrigeration. Most theophylline products are taken for many months, but the exact length of treatment depends on the individual medication and your health needs.
For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
