Quibron-T/SR (Theophylline) must be used regularly to prevent wheezing and shortness of breath. This drug belongs to a class of drugs known as xanthines. It works by relaxing the muscles in the airways so that they open up and you can breathe more easily. It also reduces the lungs' response to stimuli. Eliminating the symptoms of breathing problems can reduce the time lost at work or school. This medication must be used regularly for it to be effective. It does not work right away and should not be used to relieve sudden breathing problems. If sudden shortness of breath occurs, use a fast-acting inhaler as directed.
Quibron-T (Theophylline) is usually prescribed by a specialist for adults and children whose asthma is poorly treated with other medications. Theophylline is not suitable for everyone, including people with certain medical conditions or those taking certain medications. It is very important that the person prescribing your asthma medications knows your entire medical history and understands what other medications you are taking. Some people with asthma are prescribed theophylline as an adjunct treatment, as well as their usual inhalers to relieve and prevent asthma. Theophylline relaxes the smooth muscles of the airways so that they open up and allow air to pass through more easily.
When you take Quibron-T, it is usually in a pill or capsule that lasts all day. It helps manage the day-to-day symptoms of asthma by opening up the airways and making breathing easier. It works in conjunction with your preemptive inhaler to lower your risk of an asthma attack. Theophylline is also used in hospital emergencies. It is injected directly into a vein (intravenously) to relieve asthma symptoms if an attack of shortness of breath or an asthma attack occurs. You will only be given theophylline intravenously if you are in the hospital. The doctor or nurse who will give it to you will make sure you get the correct dose and answer any questions you may have.

I'm happy with the result. And now I feel like I can live a normal life. Quibron-T Great product. Thank. I'm sure it saved my life because when I started I could hardly breathe. The only problem I have with the drug is that I have to be careful with drug interactions as it does not stack well with many other drugs.
This is the only medicine I take for acute asthma. I have been taking Theophylline for 10 years. This is the best. This has really helped me with asthma and I recommend others to try. This drug provides me with an excellent quality of life and almost completely controls my chronic asthma.
