Theophylline Pharmacological Information

Medication Information: Theophylline is an airway dilator that is prescribed for people with respiratory problems such as asthma and obstructive pulmonary disease (COPD). This medicine can be taken in the form of tablets or capsules.

Theophylline relaxes the muscles around the airways and allows air to flow freely through them. This makes breathing easier and reduces symptoms such as coughing, wheezing and shortness of breath. It is important to always take a brand of theophylline. This is because the amount of theophylline absorbed by the body varies in different brands. If you use another brand, you will most likely get either a lot more or a lot less theophylline.


Contraindications to theophylline

Note the expiration date of theophylline and do not take it if it has expired.

Never give theophylline to anyone else, even if you have the same symptoms.

Do not take more than the dose prescribed by your doctor.

Check for drug interactions and be sure to tell your doctor what other medications you are taking.


Drug interaction of theophylline

Drug interactions may alter drug performance and increase the risk of serious side effects. Make a list of all the medicines (including prescription / over-the-counter and herbal medicines) you use and share them with your doctor and pharmacist.

Theophylline may interact with rheosygate.

Caffeine and alcohol can increase the side effects of theophylline. Avoid drinking large amounts of alcohol or caffeinated beverages (coffee, tea, black soda) or eating large amounts of chocolate or caffeinated foods.

Smoking lowers blood levels of theophylline. Tell your doctor if you smoke or have recently stopped smoking.

Theophylline is very similar to aminophylline and oxtriphylline. Do not take drugs containing aminophylline or xetriphillin while using theophylline.

Theophylline may interfere with certain medical tests (such as blood sugar, cholesterol, uric acid, dipyridamole-thallium imaging tests) and cause erroneous results. Inform laboratory personnel that you have used theophylline before the test.
