This medication contains 2 drugs (oxtriphylline and guaifenesin) and is used to treat and prevent wheezing and trouble breathing caused by ongoing lung disease (such as asthma, chronic bronchitis, emphysema). Oxtriphylline belongs to a class of drugs known as xanthines and is changed in the body to theophylline. Theophylline works by relaxing the muscles around the airways so that they open up and you can breathe more easily. It also decreases the lungs' response to irritants. Guaifenesin is an expectorant that helps thin and loosen mucus in the lungs, making it easier to cough up the mucus. Controlling symptoms of breathing problems can decrease time lost from work or school.
This medication does not work right away and should not be used to relieve sudden attacks of breathing trouble. If an attack occurs, use your quick-relief inhaler (such as albuterol) as prescribed by your doctor.
How to use Brophylline Elixir
Take this medication by mouth, usually every 6 hours, with a full glass of water (8 ounces or 240 milliliters) or as directed by your doctor. If stomach upset occurs, take it with food. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.
The dosage is based on your age, medical condition, response to treatment, and other drugs you may be taking. (See also Drug Interactions section.)
Alcohol and caffeine can increase the side effects of this medication. Avoid drinking large amounts of beverages containing alcohol or caffeine (coffee, tea, colas), eating large amounts of chocolate, or taking nonprescription products that contain caffeine.
This medicine works best when the amount in your body is kept at a constant level. Therefore, use this drug at evenly spaced intervals. To help you remember, take it at the same times each day. Do not increase your dose unless your doctor directs you to do so. Taking too much of this medication may cause serious side effects.
Be sure you understand which medications to use on a regular basis (controller drugs such as this medication) and which to use as needed for sudden attacks of breathing trouble (quick-relief medications). Consult your doctor about what you should do if your breathing worsens (for example, if you have increased coughing or shortness of breath, or if you wake up at night with breathing trouble).
Also discuss what to do if this medication stops working well. Watch for signs of worsening breathing problems and report them to your doctor promptly. Your doctor may need to change your dose of controller medications or may prescribe other drugs that may work better for you. Signs of worsening breathing problems include needing to use your quick-relief inhaler more often (more than 2 days a week, more than 1 canister a month), or having peak flow meter readings in the yellow/red range. Get instructions from your doctor about when you can treat breathing problems by yourself and when you must seek immediate medical attention.
Stomach pain/cramping, pounding heartbeat, nausea, vomiting, headache, trouble sleeping, diarrhea, irritability, restlessness, shaking, and increased urination may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
