What is the most important information I should know about 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.
