mild-to-moderate persistent asthma. It is usually used
with an inhaled corticosteroid. It can be used by itself or with an inhaled
corticosteroid to control symptoms at night.
Theophylline is considered an
alternative medicine for persistent asthma in adults. Inhaled corticosteroids
are preferred. It is also considered an alternative addition to inhaled
corticosteroids in moderate persistent asthma in children and adults.

All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

medicines to calm people, heart medicines, and seizure medicines),
alcohol, and some medical conditions can affect the levels of theophylline in

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
