Leaflet: information for the user

Seretide 25 micrograms/50 micrograms/inhalation, suspension for inhalation in a pressurised container

salmeterol/fluticasone propionate

Read this leaflet carefully before you start using this medicine, because it contains important information for you.

• Keep this leaflet, as you may need to read it again.
• If you have any questions, ask your doctor or pharmacist.
• This medicine has been prescribed for you only, and you must not give it to others even if they have the same symptoms as you, as it may harm them.
• If you experience any side effects, consult your doctor or pharmacist, even if they are not listed in this leaflet. See section 4.

Seretide contains two active ingredients, salmeterol and fluticasone propionate:

• Salmeterol is a long-acting bronchodilator. Bronchodilators help keep the airways in the lungs open, making it easier for air to enter and leave. The effects last for at least 12 hours.
• Fluticasone propionate is a corticosteroid that reduces inflammation and irritation in the lungs.

Your doctor has prescribed this medication to help prevent respiratory problems such as asthma.

You must use Seretide every day as recommended by your doctor. This will ensure the medication works correctly in controlling your asthma.

Seretide helps prevent shortness of breath and wheezing. However, Seretide should not be used to relieve a sudden attack of shortness of breath or wheezing. In such a case, you should use your quick-relief medication, such as salbutamol. You must carry your quick-relief medication with you at all times.

Do not use Seretide

• if you are allergic to salmeterol, fluticasone propionate or to any of the other ingredients, norflurane (HFA 134a).

Warnings and precautions

Consult your doctor before starting to use Seretide if you have:

• Cardiac abnormalities, including rapid or irregular heartbeat.
• Hyperthyroidism.
• High blood pressure.
• Diabetes mellitus (Seretide may increase blood sugar levels).
• Low levels of potassium in the blood.
• Tuberculosis (TB) today or in the past, or other lung infections.

Contact your doctor if you experience blurred vision or other visual disturbances.

Other medications and Seretide

Inform your doctor or pharmacist if you are using, have used recently or may need to use any other medication, including those for asthma or those obtained without a prescription. This is because, in some cases, Seretide should not be administered with other medications.

Inform your doctor if you take any of the following medications before starting to use Seretide:

• β-blockers (such as atenolol, propranolol and sotalol). β-blockers are used mainly to treat hypertension or other cardiac conditions.
• Medications to treat infections (such as ketoconazole, itraconazole and erythromycin), including some HIV medications (such as ritonavir, cobicistat). Some of these medications may increase the amount of fluticasone propionate or salmeterol in your body. This may increase your risk of experiencing adverse effects with Seretide, including irregular heartbeats, or may worsen the adverse effects. Your doctor may perform close monitoring if you are taking these medications.
• Corticosteroids (oral or injectable). If you have taken these medications recently, you may increase the risk of this medication affecting your adrenal gland.
• Diuretics, also known as medications to urinate, used to treat high blood pressure.
• Other bronchodilators (such as salbutamol).
• Medications containing xanthine. They are often used to treat asthma.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or if you think you may be pregnant or intend to become pregnant, consult your doctor or pharmacist before using this medication.

Driving and operating machinery

Seretide is unlikely to affect your ability to drive or operate machinery.

Follow exactly the administration instructions of this medication as indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

• Use Seretide every day, until your doctor tells you to stop. Do not take more than the recommended dose. If in doubt, consult your doctor or pharmacist.
• Do not stop taking Seretide or reduce your dose without talking to your doctor first.
• Seretide must be inhaled through the mouth into the lungs.

Seretide is not recommended for use in children under 4 years of age.

Your symptoms may be well controlled using Seretide twice a day. If so, your doctor may decide to reduce your dose to once a day. The dose may change to:

• once at night if you have nocturnal symptomssymptoms,
• once in the morning if you have diurnal symptomssymptoms.

It is very important that you follow your doctor's instructions on how many applications and how often you should administer them.

If you are using Seretide to treat asthma, your doctor will want to monitor your symptoms regularly.If your asthma worsens or you have greater difficulty breathing, see your doctor immediately. You may notice more wheezing, or a feeling of choking more often, or that you have to use your rescue medication more frequently. If any of these things happen, you should continue using Seretide, but do not increase the number of applications. Your respiratory disease may worsen and seriously ill. See your doctor, as you may need additional treatment.

Instructions for use

• Your doctor, nurse, or pharmacist should teach you how to use your inhaler. Periodically, they should check how you use it. Not using Seretide inhaler properly or as prescribed, may result in your asthma not improving as it should.
• The medication is located in a pressurized cartridge within a plastic casing with a mouthpiece.
• The inhaler has a counter on the back that informs you of how many applications are left. Each time you activate the inhaler, one application will be released and the counter will decrease by one unit.
• Be careful not to drop the inhaler, as this may cause the counter to decrease some units.

Checking the inhaler

1. If you are using the inhaler for the first time, check that it works properly. Remove the mouthpiece protector by pressing it gently on both sides with your thumb and index finger and pulling it off.

1. To ensure it works, shake the inhaler well,point the mouthpiece away from youand pressthe cartridge downto release one application into the air.Repeat these steps, shaking the inhaler before releasing each application, until the counter marks 120. If you have not used your inhaler for a week or more, release two applications of the medication into the air.

Using the inhaler

It is essential to start inhaling as slowly as possible just before using your inhaler.

1.It is recommended that you stand or sit upright while using the inhaler.

2.Remove the mouthpiece protector (as shown in the figure). Check inside and out that the mouthpiece is clean and there are no foreign particles.

3.Shake the inhaler 4 or 5 times to ensure the removal of any foreign particles and that the contents of the inhaler are mixed properly.

4.Hold the inhaler in a vertical position with your thumb on the base of the inhaler, below the mouthpiece. Exhale as much air as possible.

5.Place the mouthpiece in your mouth, between your teeth. Close your lips around the mouthpiece. Do not bite it.

6.Take a deep breath in through your mouth slowly and deeply. Immediately after starting to breathe in, press firmly on the top of the inhaler to release the medication. Do this while continuing to breathe in deeply and constantly.

7.Hold your breath, remove the inhaler from your mouth by releasing your thumb from the top of the inhaler. Continue holding your breath for a few seconds, as long as possible.

8.Wait approximately half a minute between each application of the medication and then repeat steps 3 to 7.

1. Afterwards, rinse your mouth with water and spit it out and/or brush your teeth. This will help prevent mouth ulcers and sore throat.

1. After using it,always put the mouthpiece protector back on immediately, to preserve it from dust. When the mouthpiece protector is put back on correctly, it will make a “click”. If it does not make a “click”, turn the mouthpiece protector, put it the other way around and try again. Do not use excessive force.

Take your time in steps 4, 5, 6, and 7. It is essential that you breathe out as slowly as possible just before using the inhaler. The first time you use the inhaler, you should use it in front of a mirror. If you see “fog” coming out of the top of the inhaler or from the sides of your mouth, you should start again from step 3.

Just like with all inhalers, caregivers should ensure that children using Seretide Inhaler use the inhalation technique described above correctly.

If you or your child find it difficult to use the inhaler, your doctor, nurse, or other healthcare professional may recommend using the inhaler with the Volumatic inhalation chamber. Your doctor, nurse, pharmacist, or other healthcare professional should show you how to use the inhalation chamber with your inhaler, how to store your inhalation chamber, and answer any questions you may have. If you are using the inhalation chamber with your inhaler, it is essential that you do not stop using it without consulting your doctor or nurse first. Also, it is essential that you do not change the type of inhalation chamber you are using without consulting your doctor. If you stop using the inhalation chamber or change the type of inhalation chamber, your doctor may need to change the dose of medication needed to control your asthma. Always consult your doctor before making any changes to your asthma treatment.

Some children or people with little hand strength may find it easier to hold the inhaler with both hands. Place both index fingers on the top of the inhaler and both thumbs on the base, below the mouthpiece.

You should get a replacement inhaler when the marker indicates 020. Stop using the inhaler when the marker indicates 000, as the remaining applications in the cartridge may not be enough to complete a dose. Never try to modify the marker number or remove the marker from the metal cartridge.

Cleaning the inhaler

To prevent your inhaler from blocking, it is essential to clean it at least once a week.

To clean your inhaler:

• Remove the mouthpiece protector.
• Do not remove the metal cartridge from the plastic casing at any time.
• Clean the inside and outside of the mouthpiece and plastic casing with a dry cloth.
• Put the mouthpiece protector back on. It will make a “click” when it is put back on correctly. If it does not make a “click”, turn the mouthpiece protector, put it the other way around and try again. Do not use excessive force.

Do not immerse the metal cartridge in water.

If you use more Seretide than you should

It is very important to use the inhaler as instructed. If you accidentally take a higher dose than recommended, consult your doctor or pharmacist. You may notice that your heart beats faster than normal and you feel tremors. You may also have headaches, dizziness, muscle weakness, and joint pain.

If you have used high doses for a long time, you should ask your doctor or pharmacist for advice. This is because high concentrations of Seretide can reduce the amount of steroid hormones produced by the adrenal gland.

In case of overdose, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medication and the amount administered.

If you forget to use Seretide

Do not take a double dose to compensate for the missed doses. Take the next dose at the usual time.

If you interrupt treatment with Seretide

It is very important to use Seretide every day as instructed.Continue taking it until your doctor tells you to stop. Do not stop using Seretide abruptly.This may worsen your breathing.

Additionally, if you stop taking Seretide suddenly or reduce your dose, you may (very rarely) cause problems with your adrenal gland (adrenal insufficiency), which sometimes causes adverse effects.

These adverse effects may include any of the following:

• Stomach pain.
• Fatigue and loss of appetite, feeling unwell.
• Discomfort and diarrhea.
• Weight loss.
• Headaches or drowsiness.
• Low blood sugar levels.
• Hypotension and convulsions (seizures).

When your body is under stress, such as fever, trauma (e.g., car accident), infection, or surgery, adrenal insufficiency may worsen and you may experience any of the adverse effects listed above.

If you have any adverse effects, consult your doctor or pharmacist. To prevent these symptoms, your doctor may prescribe an additional dose of corticosteroids in tablets during that time (such as prednisolone).

If you have any other questions about using this medication, ask your doctor, nurse, or pharmacist.

Like all medicines, this medicine can cause side effects, although not everyone will experience them. To reduce the occurrence of side effects, your doctor will prescribe the lowest dose of Seretide that controls your asthma.
