Theophylline

About Theophylline

This belongs to the group of medicines known as xanthine-derivative bronchodilators.

Theophylline can be used to treat asthma, bronchitis, emphysema and other lung and airway related problems.

Bronchodilators work by opening up the air passages in the lungs so that air can flow into the lungs more freely. In doing so they help to relieve symptoms such as coughing, wheezing and shortness of breath.

Theophylline is available in in modified release tablet or capsule form, which means Theophylline is released slowly over the day to give an even effect.

It is also sometimes known as: Nuelin SA; Slo-Phyllin; Uniphyllin Continus. You may notice the use of any of these names on the packaging of your medicine.

Before Taking Theophylline

Before taking Theophylline make sure your doctor or pharmacist knows:

• if you are pregnant, trying for a baby or breast-feeding
• if you suffer from liver or heart problems
• if you suffer from epilepsy or high blood pressure
• if you have a stomach ulcer
• if you are a smoker or drink a lot of alcohol
• if you have hyperthyroidism (an over active thyroid gland)
• if you suffer from porphyria (a blood disorder)
• if you have ever had an allergic reaction to this or any other medicine
• if you are taking any other medicines, including those available to buy without a prescription, herbal and complementary medicines

How to Take Theophylline

• Take your medication exactly as directed by your doctor.
• Always read the manufacturer's information leaflet, if possible, before beginning treatment.
• Try to take each dose at the same times each day to avoid missing any doses. If you do miss a dose take it as soon as you remember, unless it is time for the next dose in which case leave out the missed dose. Never take two doses at the same time to make up.
• Take Theophylline with or immediately after food.
• Swallow the modified release form of Theophylline whole (not chewed or crushed).
• Taking your last dose of Theophylline just before bedtime should help with night time asthma and early morning wheezing.
• Never take more than the prescribed dose. If you suspect that you or someone else has taken an overdose of Theophylline contact your doctor or go to the accident and emergency department of your local hospital at once. Always take the container with you, if possible, even if empty.
• This medicine is for you. Never give it to others even if their condition appears to be the same as yours.

Getting the most from your treatment

• Before taking any 'over-the-counter' medicines, check with your pharmacist which medicines are safe for you to take alongside Theophylline.
• Do not stop taking Theophylline without speaking to your doctor first.
• Make sure that you receive the same brand of theophylline each time you collect your medicine. If the packaging looks different from before check with your pharmacist.
• Keep your regular doctors appointments so your progress can be monitored
• Do not smoke. Smoking causes severe irritation and damage to the lungs. It will make your condition worse and will reduce the beneficial effects of your medication.
• If you have diabetes: Check your blood glucose levels regularly as this preparation can affect the levels of sugar in your blood.

Can Theophylline cause problems?

Along with their useful effects, all medicines can cause unwanted side effects, which usually improve as your body adjusts to the new medicine. Speak to your doctor or pharmacist if any of the following side effects continue or become troublesome:

If you experience any other worrying symptoms, which you think may be due to this medicine, discuss them with your pharmacist.
