Serevent belongs to a group of medicines called bronchodilators.

Serevent is indicated for the regular long-term treatment of reversible airway obstruction caused by asthma and chronic bronchitis (COPD). In asthma, it will be administered in combination with a long-term anti-inflammatory therapy with inhaled or oral glucocorticoids.

Do not use Serevent

• if you are allergic to salmeterol or any of the other ingredients in this medication (listed in section 6).

Warnings and precautions

Consult your doctor or pharmacist before starting to use Serevent:

• If you have ever had to stop taking any other medication for your condition due to allergy or other reasons.
• If you are being treated for any thyroid disorder.
• If you are being treated for high blood pressure.
• If you are being treated for heart problems.
• If you have diabetes mellitus.
• If you are prone to low levels of potassium in the blood.
• If you are being treated with ketoconazole (a medication used to treat fungal infections).

If you are using Serevent for asthma treatment, your doctor will want to see you regularly to check your symptoms. Go to your doctor immediately if:

• Your asthma worsens.
• You have greater difficulty breathing.
• You notice more wheezing.
• You feel more choking sensations.
• You need to use your rescue medication more frequently.

If any of the above situations occur, do not increase the number of Serevent applications (your respiratory condition may worsen and you may become seriously ill). Go to your doctor as it may be necessary to change your asthma medication.

Patients who have been previously treated with Serevent should know that it no longer contains chlorofluorocarbon (CFC) propellants for aerosols. It should be used exactly as instructed by your doctor. Your doctor may change your dosage regimen.

The active ingredient in Serevent without CFCs is exactly the same as the one in the Serevent that contained CFCs. The only differences you may notice are the taste and the sensation of the spray in your mouth, as well as the sound of the inhaler during use. This is due to the change of propellant to eliminate the CFCs. This modification does not affect the mechanism of action of the medication. Serevent without CFCs can be used in the same way as the previous one.

Other medications and Serevent

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

Important information about some of the components of Serevent

Use in athletes: this medication contains salmeterol, which may produce a positive result in doping control tests.

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

Remember to use your medication. IT IS VERY IMPORTANT THAT IT IS USED REGULARLY EVERY DAY. This will help you stay free of symptoms throughout the day and at night.

Your doctor will indicate the duration of your treatment with Serevent. Do not suspend treatment before, even if you feel better, unless your doctor tells you to.

Serevent should only be used by inhalation and should not be used in children under 4 years old.

If you have been prescribed Serevent for your asthma, you must continue using any other medication you are taking to control your asthma. These should include an inhaled corticosteroid or tablets. Continue taking the same doses as before, unless your doctor tells you otherwise. Do this even if you feel better. Do not stop taking your inhaled corticosteroid (or tablets) when you start using Serevent.

It is very important that you follow your doctor's instructions on how many times and how often you should use Serevent. The usage instructions are given below. If you have difficulties or do not understand the instructions, ask your doctor or pharmacist.

The recommended dose is:

Adults

• Two inhalations (50 micrograms) twice a day. If your doctor advises you, you can increase this dose to four inhalations (100 micrograms) twice a day.

Use in children and adolescents

• Children over 4 years old: two inhalations (50 micrograms) twice a day.

If you estimate that the action of Serevent is too strong or too weak, inform your doctor or pharmacist.

Usage instructions:

Before using for the first time the inhaler or if it has not been used for a week or more, remove the mouthpiece protector by pressing it gently on both sides, shake the inhaler well, and release two puffs into the air to ensure the inhaler's proper functioning.

Using the inhaler:

1. Remove the mouthpiece protector, pressing it gently on both sides.

1. Check that there are no foreign particles inside and outside the inhaler, including the mouthpiece.

1. Shake the inhaler well to ensure the elimination of any foreign particles and that the inhaler's content is properly mixed.

1. Hold the inhaler in a vertical position between the index and middle fingers, placing the thumb on the base, below the mouthpiece.

1. Breathe in as much air as possible and then introduce the mouthpiece into the mouth, between the teeth, closing the lips over the device, but not biting it.

1. Immediately after starting to breathe in through the mouth, press the top of the inhaler to release the medication and continue breathing in deeply and constantly.

1. Hold your breath and remove the inhaler from the mouth, taking your finger off the top of the inhaler. Continue holding your breath as long as possible.

1. If you are going to administer another inhalation, hold the inhaler in a vertical position and wait for approximately half a minute before repeating steps 3 to 7.

1. Replace the mouthpiece protector by pushing it firmly and adjusting it until you hear a click.

IMPORTANT

Do not perform steps 5, 6, and 7 quickly. It is essential to start breathing as slowly as possible, just before pressing the inhaler.

Practice in front of a mirror during the first times. If you notice a "kind of fog" coming out of the top of the inhaler or from the sides of the mouth, start again from step 2.

Patients who find difficulty in coordinating the inhaler's handling with the inhalation may use an appropriate inhalation chamber (BABYHALER, inhalation chamber for children up to 5 years old).

Small children may need help, with their parents handling the inhaler for them. Encourage the child to breathe in and handle the inhaler just after the child starts breathing in. Practice together the technique. Older children or people with fragile hands should hold the inhaler with both hands; for this, they will place the two index fingers on the top of the inhaler and the two thumbs on the base, below the mouthpiece.

If your doctor has given you different instructions for using the inhaler, follow them carefully. Inform your doctor if you have any difficulties.

Cleaning:

Clean the inhaler at least once a week.

1. Remove the mouthpiece protector.
2. Do not remove the cartridge from the plastic casing.
3. Clean the mouthpiece and the plastic casing from the inside and outside with a dry cloth, a paper handkerchief, or a small piece of cotton.
4. Replace the mouthpiece protector.

DO NOT SUBMERGE THE METAL CONTAINER IN WATER.
