What is Elixophyllin (theophylline)?
Theophylline is a bronchodilator. It works by relaxing muscles in the lungs and chest, and makes the lungs less sensitive to allergens and other causes of bronchospasm.
Theophylline is used to treat the symptoms of asthma, bronchitis and emphysema.
Theophylline may also be used for other purposes not listed in this medication guide.
What is the most important information I should know about Elixophyllin (theophylline)?
If there are any changes in the brand, strength, or type of theophylline you use, your dosage needs may change. Always check your medicine when it is refilled to make sure you have received the correct brand and type as prescribed by your doctor. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.
Do not start or stop smoking without first talking to your doctor. Smoking changes the way your body uses theophylline, and you may need to use a different dose. Avoid drinks or foods that contain caffeine, such as coffee, tea, cola, and chocolate. Caffeine may increase some of the side effects of theophylline.
There are many other medicines that can interact with theophylline. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor. Keep a list with you of all the medicines you use and show this list to any doctor or other healthcare provider who treats you.
What should I discuss with my healthcare provider before taking Elixophyllin (theophylline)?
Do not use this medication if you are allergic to theophylline.
Before taking theophylline, tell your doctor if you are allergic to any drugs, or if you have:

How should I take Elixophyllin (theophylline)?
Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results from this medication.
Take this medicine with a full glass of water.
You may take theophylline with or without food, but take it the same way every time.
Do not crush, chew, break, or open an extended-release tablet or capsule unless your doctor tells you to. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill would cause too much of the drug to be released at one time.
Your doctor may tell you to break a regular theophylline tablet before you take it. Some tablets have special scored marks on them to make breaking the tablet easier. Follow your doctor's instructions.
Measure the liquid form of theophylline with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
If there are any changes in the brand, strength, or type of theophylline you use, your dosage needs may change. Always check your medicine when it is refilled to make sure you have received the correct brand and type as prescribed by your doctor. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.
Do not start or stop smoking without first talking to your doctor. Smoking changes the way your body uses theophylline, and you may need to use a different dose. Store theophylline at room temperature, away from moisture, heat, and light.
What happens if I miss a dose?
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine. Overdose symptoms may include nausea, vomiting, insomnia, tremors, restlessness, uneven heartbeats, and seizure (convulsions). Seizures caused by a theophylline overdose can cause death or permanent brain damage.
What should I avoid while taking Elixophyllin (theophylline)?
Theophylline can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
