Package Leaflet: Information for the User
Foster 100micrograms/6micrograms/puff Inhalation Solution in a pressurized container
beclometasone dipropionate/formoterol fumarate dihydrate
For use in adults.
Read this entire leaflet carefully before you start using this medicine because it contains important information for you.
Contents of the pack
Foster is an inhalation solution in a pressurized container that contains two active substances that are inhaled through the mouth and released directly into the lungs.
The two active substances are beclometasone dipropionate and formoterol fumarate dihydrate. Beclometasone dipropionate belongs to a group of medicines called corticosteroids that have an anti-inflammatory action that reduces inflammation and irritation of your lungs.
Formoterol fumarate dihydrate belongs to a group of medicines called long-acting bronchodilators that relax the muscles of the airways, making it easier for you to breathe.
These two active substances combined facilitate breathing, as they provide relief from symptoms such as difficulty breathing, wheezing, and coughing in asthmatic patients or those with COPD, and also help prevent asthma symptoms.
Asthma
Foster is indicated for the regular treatment of asthma in adult patients in whom:
Or:
COPD
Foster may also be used to treat symptoms of severe chronic obstructive pulmonary disease (COPD) in adult patients. COPD is a chronic disease of the lung airways caused mainly by smoking cigarettes.
Do not use Foster:
Warnings and precautions
Consult your doctor, pharmacist, or nurse before using Foster:
If any of the above applies to you, always inform your doctor before using Foster.
If you have or have had medical problems or allergies, or if you are not sure if you can use Foster, consult your doctor, nurse, or pharmacist before using the inhaler.
Treatment with a β2 agonist like the formoterol contained in Foster may cause a sudden drop in serum potassium levels (hypokalemia).
Be particularly careful if you have severe asthma.The reason is that a lack of oxygen in the blood and other treatments you may be receiving along with Foster, such as medications to treat heart disease or high blood pressure (known as diuretics) or other medications used to treat asthma, can worsen the drop in potassium levels. Therefore, your doctor will want to check your potassium level in the blood from time to time.
If you take higher doses of inhaled corticosteroids for prolonged periods, you may need corticosteroids in stressful situations. These situations include hospitalization after an accident, the existence of a severe injury, or before surgery. In such cases, the doctor treating you will decide if it is necessary to increase the dose of corticosteroids and may prescribe steroid tablets or injections.
In case you go to the hospital, remember to bring all your medications and inhalers, including Foster and other medications or tablets purchased without a prescription, preferably in their original packaging.
Contact your doctor if you experience blurred vision or other visual disturbances.
Children and adolescents
Foster should not be used in children and adolescents under 18 years of age until more data is available.
Other medicines and Foster
Tell your doctor if you are using or have recently used other medicines, including those purchased without a prescription.
Some medicines may increase the effects of Foster, so your doctor will monitor you closely if you are taking these medicines (including some for HIV: ritonavir, cobicistat).
Do not use beta-blockers with this medicine. If you need to use beta-blockers (including eye drops), the effect of formoterol may decrease or even be null. On the other hand, the use of other beta-adrenergic drugs (drugs that work in the same way as formoterol) may enhance the effects of formoterol.
The combined use of Foster with:
Pregnancy, breastfeeding, and fertility
There are no clinical data on the use of Foster during pregnancy.
Do not use Foster if you are pregnant or think you may be pregnant, if you plan to become pregnant, or if you are breastfeeding, unless your doctor advises you to do so.
Driving and using machines
The influence of Foster on the ability to drive and use machines is negligible.
Foster contains alcohol
Foster contains 7 mg of alcohol (ethanol) per puff, which is equivalent to 0.20 mg/kg per dose of two puffs. The amount in two puffs of this medicine is equivalent to less than 1 ml of wine or beer. The small amount of alcohol in this medicine does not produce any noticeable effect.
Foster is for inhalation use only.
Follow the administration instructions for this medication exactly as indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.
Asthma
Your doctor will periodically review you to ensure that you are taking the optimal dose of Foster. Your doctor will always adjust the treatment to the minimum dose that best controls your symptoms.
Foster may be prescribed by your doctor in two different ways:
Adults and elderly patients:
The recommended dose of this medication is one to two puffs twice a day.
The maximum daily dose is 4 puffs.
Remember: You should always carry a rapid-acting "rescue" inhaler with you to treat worsening asthma symptoms or a sudden asthma attack.
Adults and elderly patients:
The recommended dose of this medication is one puff in the morning and one puff in the evening.
You should also use Foster as a "rescue" inhaler to treat sudden asthma symptoms.
If you have asthma symptoms, inhale one puff and wait a few minutes.
If you do not feel better, inhale another puff.
Do not inhale more than 6 rescue puffs per day.
The maximum daily dose of Foster is 8 puffs.
If you think you need more puffs per day to control your asthma symptoms, contact your doctor for advice. You may need to change your treatment.
Use in children and adolescents under 18 years:
Children and adolescents under 18 years of age SHOULD NOT take this medication.
COPD
Adults and elderly patients:
The recommended dose is two puffs in the morning and two puffs in the evening.
Patients at risk:
Elderly patients do not need to have their dose adjusted. There is no information available on the use of Foster in patients with liver or kidney problems.
Foster is effective for the treatment of asthma at a dose of beclometasone dipropionate that may be lower than that of other inhalers containing the same component. If you have previously been using another inhaler that contained beclometasone dipropionate, your doctor will advise you on the exact dose of Foster you should take for asthma.
Do not increase the dose.
If you think the medication is not very effective, always consult your doctor before increasing the dose.
If you use more Foster than you should
Consult your doctor if you experience any of these symptoms.
If you forget to use Foster
Take it as soon as you remember. If it is almost time for your next dose, do not take the missed dose; just take the next dose. Do not double the dose.
If you stop treatment with Foster
Do not decrease the dose or stop using the medication.
Even if you feel better, do not stop using Foster or decrease the dose. If you want to do so, consult your doctor. It is very important to use Foster regularly even if you do not have symptoms.
If your breathing difficulties increase:
If, immediately after inhaling the medication, your difficulty breathing or wheezing (audible whistling sound) worsens, stop using Foster immediately and use your rapid-acting inhaler right away. Contact your doctor quickly. Your doctor will evaluate the symptoms and, if necessary, modify the treatment. See also section 4 "Possible side effects".
If your asthma worsens:
If your symptoms worsen or you have difficulty controlling them (for example, if you increase the frequency of use of the separate rapid-acting inhaler or Foster as a rescue inhaler), or if the rapid-acting inhaler or Foster does not help improve your symptoms, go to the doctor immediately. Your asthma may be worsening, and your doctor may need to modify the dose of Foster or prescribe an alternative treatment.
If you have any other questions about the use of this product, ask your doctor or pharmacist.
Method of administration:
This medication is in a pressurized container inside a plastic casing with a mouthpiece.
There is a counter on the back of the inhaler, which indicates how many doses are left. Each time you press the container, a puff of medication is released, and the counter decrements one dose. Avoid dropping the inhaler, as this could cause the counter to decrement a dose.
Inhaler check
Before using the inhaler for the first time, or if you have not used it for 14 days or more, you must check your inhaler to ensure it is working correctly.

How to use your inhaler
When possible, stand or sit upright to perform the inhalation.

In case you need to inhale a new dose, hold the inhaler upright for about half a minute and then repeat steps 2 to 5.
Important: Do not perform steps 2 to 5 too quickly.
After administration, close with the protective cap and check the dose counter.
You should have a replacement inhaler when the counter shows the number 20. Stop using the inhaler when the counter reads 0, as even if there are puffs left in the device, they may not be enough to take a full dose.
If some of the gas escapes from the top of the inhaler or from the corner of your lips, it means that Foster is not going to reach your lungs as it should. Take another dose following the instructions, starting again from step 2.
To reduce the risk of fungal infection in the mouth and throat, rinse your mouth or gargle with water or brush your teeth each time you use the inhaler.
If you think the effect of Foster is too strong or insufficient, consult your doctor or pharmacist.
If you find it difficult to press the inhaler while starting to breathe in, you can use the AeroChamber Plus device. Consult your doctor, pharmacist, or nurse about using this device.
It is essential that you read the leaflet that comes with the AeroChamber Plus device and follow the instructions carefully on how to use the AeroChamber Plus device and how to clean it.
Cleaning
You should clean the inhaler once a week. When you clean it, do not remove the pressurized container from the device, and do not use water or other liquids to clean the inhaler.
To clean the inhaler:
Like all medicines, this medicine can cause side effects, although not everybody gets them.
As with other inhaler treatments, there is a risk of worsening breathing difficulties and wheezing immediately after using Foster, which is known as paradoxical bronchospasm. If this happens, STOP using Fosterand use your rapid-acting inhaler right away to treat breathing difficulty and wheezing symptoms. Contact your doctor immediately.
