Aminophylline

About aminophylline

Aminophylline is an oral bronchodilator medicine which is prescribed for people with breathing problems, such as asthma and chronic obstructive pulmonary disease (COPD). It is a medicine that you take by mouth as a tablet. It is also available as an injection, but this is usually given in a hospital environment. Aminophylline is actually a mixture of a medicine called theophylline, and ethylenediamine. The ethylenediamine is used to improve how well the active medicine, theophylline, dissolves.

This medicine works by opening up the air passages in your lungs so that air can flow into your lungs more freely. This makes breathing easier and helps relieve symptoms such as coughing, wheezing and shortness of breath.

Before taking aminophylline

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking aminophylline it is important that your doctor or pharmacist knows:

• Si vous êtes enceinte, si vous essayez d'avoir un enfant ou si vous allaitez.

• If you have a heart condition or liver problems.

• If you have an overactive thyroid gland gland (hyperthyroidism).

• Si vous souffrez d'hypertension artérielle.

• Si vous souffrez d'un ulcère de l'estomac.

• If you drink alcohol or smoke.

• Si vous êtes épileptique.

• If you are currently unwell with a high temperature.

• Si vous êtes atteint d'une maladie sanguine héréditaire rare appelée porphyrie.

• Si l'on vous a dit que vous aviez un faible taux de potassium dans le sang.

• Si vous prenez ou utilisez d'autres médicaments ou inhalateurs. Cela inclut tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

• Si vous avez déjà eu une réaction allergique à un médicament.

How to take aminophylline

• Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about aminophylline and a full list of side-effects which you may experience from taking it.

• Aminophylline is taken twice a day, in the morning and evening. Always try to take your doses 12 hours apart and at the same times each day. For example, at 8 am and 8 pm each day. You can take the tablets before or after meals.

• Swallow the tablets whole with a drink of water. Do not chew, break, or crush them.

• There are two different strengths of tablet available, and you will be asked to take either one or two tablets for each of your doses. Your dose may be adjusted over the first few weeks, depending on the results of some blood tests. The tests allow your doctor to make sure that you have the dose that helps your condition, but avoids any unwanted symptoms.

• Your doctor or pharmacist will tell you what strength of tablet is right for you and how many tablets to take for each dose. Your dose will also be on the label of the pack to remind you.

• If you forget to take a dose but it is still within four hours of the time you should have taken it, take a dose as soon as you remember. If it is more than four hours since you should have taken it, do not take the missed dose but do remember to take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

Tirer le meilleur parti de votre traitement

• Continue to take aminophylline unless your doctor tells you otherwise. Bronchodilators like aminophylline are usually prescribed long-term.

• Essayez de respecter vos rendez-vous réguliers avec votre médecin. Il pourra ainsi examiner régulièrement votre état de santé. Votre médecin voudra effectuer des analyses de sang de temps en temps pour s'assurer que vous recevez la bonne dose et pour vérifier les niveaux de potassium dans votre sang.

• The amount of aminophylline in your blood should be kept within a certain range. It can vary if you are unwell, or if you start or stop smoking, take other medicines, or if you drink more alcohol than usual. This is because these things interfere with the way aminophylline is handled by your body. Some of these things will increase the amount of medicine in your body, leading to side-effects. Others will reduce it, leading to your treatment not being as effective as it should be.

• Si, à tout moment, vous constatez que vos symptômes s'aggravent, contactez immédiatement un médecin ou une infirmière pour obtenir des conseils.

• If you want to buy any medicines, check with a pharmacist that they are safe for you to take. Some medicines (including the herbal remedy St John's wort) can affect the levels of aminophylline in your blood and should not be taken alongside it without your doctor knowing.

• Some vaccines, such as the flu vaccine, may also affect aminophylline levels. Make sure you tell your doctor about any vaccinations you have.

• If you are due to have an operation or any dental treatment, tell the person carrying out the treatment which medicines you are taking, as some anaesthetics can interfere with aminophylline.

• Aminophylline can be very toxic in overdose. If you suspect that someone has taken more than they should (and especially if it is a child), go to the accident and emergency department of your local hospital straightaway. Take the container with you, even if it is empty.
