Theolair Liquid (Theophylline Anhydrous) is a prescription medication used to treat lung diseases, including asthma and chronic obstructive pulmonary disease (bronchitis, emphysema). It must be used regularly to prevent wheezing and shortness of breath. The active ingredient in Theolair Liquid is anhydrous Theophylline. Theophylline belongs to a class of drugs known as xanthine. It works by relaxing the muscles around the airways so that they open and allow for easy breathing. It also decreases the lungs' response to irritants such as dust or pollens. Controlling symptoms of breathing problems can prevent school absenteeism.

The common side effects of Theolair Liquid are nausea, vomiting, headache, trouble sleeping, nervousness, and increased urination.

• Allergic reactions such as shortness of breath, swelling of face, lips, and joints;
• Seizure;
• Severe dizziness;

• Worsening of your breathing pattern;
• Worsening restlessness and lack of coordination

Warnings and Interactions

Before using anhydrous Theophylline, inform your doctor if you are allergic to it or other xanthine drugs, including aminophylline, oxtriphylline, caffeine, or other allergies. Theophylline is a liquid and should be taken orally, usually once or twice daily, as your doctor prescribes. Follow your doctor's prescription label carefully and use it as directed. Theolair liquid does not work immediately and should not be used to relieve sudden breathing problems. If sudden shortness of breath occurs, use your quick-relief inhaler as prescribed. Measure the required dose carefully using a special measuring spoon. Do not use a household spoon because you may not get the correct dose.
