DIN (Drug Identification Number)


How does this medication work? What will it do for me?

Beclomethasone inhaler belongs to the group of medications called inhaled corticosteroids, which help prevent asthma attacks by decreasing inflammation in the lungs and thereby opening the airways. When used regularly every day, inhaled beclomethasone decreases the number and severity of asthma attacks. However, it will not relieve an asthma attack that has already started.

After starting the medication, you should see improvement in asthma symptoms in about 1 to 2 weeks. It may take 3 to 4 weeks to see the full benefits. If you do not notice any improvement in your asthma symptoms after 1 week, contact your doctor.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

How should I use this medication?

The dose of beclomethasone inhaler should be individualized. The dose used should be the lowest one required to control asthma symptoms.

For adults and children over 12 years of age, the usual dose ranges from 50 µg to 400 µg twice daily (the number of inhalations varies depending on strength of medication used).

For children 5 to 11 years of age, the usual dose is 50 µg to 100 µg twice daily.

Once your asthma symptoms are controlled, your doctor may suggest that you reduce the dose gradually to ensure you are using the lowest dose needed.

Inhaled beclomethasone is used to prevent asthma attacks. It is not used to relieve an attack that has already started. For relief of an asthma attack that has already started, you should use a "reliever" medication. If you do not have another medication to use for an attack or if you have any questions about this, check with your health care professional.

If your doctor has asked you to use a "reliever" inhaler such as salbutamol or terbutaline with your beclomethasone inhaler, you should use the reliever inhaler first, wait several minutes, and then use the beclomethasone inhaler. The reliever medication will provide immediate relief of symptoms of the asthma attack, while the beclomethasone inhalation works to treat and control asthma regularly.

See the package insert or speak with your pharmacist for instructions on using the inhaler properly.

Rinsing your mouth and gargling with water after each dose can help prevent hoarseness, throat irritation, and infection in the mouth caused by candidiasis (a type of yeast infection of the mouth, also known as "thrush"). If you have dentures, they should be cleaned after each dose.

Use this medication only as directed. Do not use more of it and do not use it more often than what your doctor recommended. Doing so may increase the chance of side effects.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

It is important to use this medication exactly as prescribed by your doctor. If you miss a dose, administer it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not administer a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice. Also do not stop using beclomethasone inhaler suddenly without talking to your doctor.

Store this medication at room temperature and keep it out of the reach of children. Do not puncture the canister and do not store the medication near heat or an open flame. The canister may burst if it is exposed to high temperatures.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
