2. What you need to know before you start using Serevent

Do not use Serevent

Warnings and precautions

Talk to your doctor or pharmacist before you start using Serevent:

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

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

  • Your asthma gets worse.
  • You have more difficulty breathing.
  • You wheeze more.
  • You feel short of breath more often.
  • You need to use your rescue medication more often.

If you experience any of the above situations, do not increase the number of applications of Serevent (your respiratory condition may worsen and you may become seriously ill). Go to your doctor as you may need to have your medication for your asthma changed.

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

The active ingredient of CFC-free Serevent is exactly the same as that of Serevent that contained CFCs. The only differences you may notice are the taste and the feeling of the spray in your mouth, as well as the sound of the inhaler during use. This is due to the change in propellant to eliminate CFCs. This modification does not affect the mechanism of action of the drug. CFC-free Serevent can be used in the same way as before.

3. How to use Serevent

Follow your doctor's instructions for using this medicine exactly. If you are in doubt, consult your doctor or pharmacist again.

Remember to use your medicine. IT IS VERY IMPORTANT TO USE IT REGULARLY EVERY DAY. This will help you stay symptom-free throughout the day and night.

Your doctor will tell you how long to use Serevent. Do not stop 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 of age.

If you have been prescribed Serevent for your asthma, you should continue to use any other medicine you are taking to control your asthma. These should include an inhaled corticosteroid or tablets. Continue to take 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 about how many times and how often you should use Serevent. The instructions for use 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 to, you can increase this dose up to four inhalations (100 micrograms) twice a day.

Use in children and adolescents

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

If you think the effect of Serevent is too strong or too weak, tell your doctor or pharmacist.

Instructions for use:

Before using the inhaler for the first time or if it has not been used for a week or more, remove the mouthpiece cover by squeezing gently on the sides, shake the inhaler well, and release two applications into the air to ensure the inhaler is working.

Using the inhaler:

  1. Remove the mouthpiece cover by squeezing gently on the sides.

Hand holding a device applicator with a needle and a gray transparent cartridge with a white arrow indicating the direction

  1. Check that there are no foreign particles inside and outside the inhaler, including the mouthpiece.
  1. Shake the inhaler well to ensure that any foreign particles are eliminated and that the contents of the inhaler are mixed properly.

Hand holding an auto-injector with a curved white arrow indicating the rotation movement of the device

  1. Hold the inhaler upright between your index and thumb fingers, placing your thumb on the base, below the mouthpiece.

Medicine questions

Started taking the medicine and have questions?

Discuss your symptoms and treatment with a doctor online.

IMPORTANT

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

Practice in front of a mirror during the first few times. If you see a "mist" coming out of the top of the inhaler or the sides of your mouth, start again from step 2.

Patients who have difficulty coordinating the use of the inhaler with inhalation may use a suitable spacer device (BABYHALER, spacer device for children up to 5 years).

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

  2. Do not remove the cartridge from the plastic casing.
