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.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. 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.
What form(s) does this medication come in?
Each pressurized, metered-dose inhaler actuation, intended for oral inhalation only, delivers beclomethasone dipropionate 50 µg from the valve, equivalent to beclomethasone dipropionate 40 µg from the actuator. Nonmedicinal ingredients: HFA-134a propellant (hydrofluoroalkane-134a or 1,1,1, 2 tetrafluoroethane) and ethanol. This medication does not contain chlorofluorocarbons (CFCs). Particle size of the emitted aerosol spray is 1 to 1.2 microns.
Each pressurized, metered-dose inhaler actuation, intended for oral inhalation only, delivers beclomethasone dipropionate 100 µg from the valve, equivalent to beclomethasone dipropionate 80 µg from the actuator. Nonmedicinal ingredients: HFA-134a propellant (hydrofluoroalkane-134a or 1,1,1, 2 tetrafluoroethane) and ethanol. This medication does not contain chlorofluorocarbons (CFCs). Particle size of the emitted aerosol spray is 1 to 1.2 microns.
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.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Asthma attacks: This medication is not a "reliever" medication. If you start developing asthma symptoms, be sure to use your "reliever" medication for rapid relief of your asthma symptoms. It is very important that you ha
he risk of fracture. Your doctor will monitor your bone health while you are taking this medication.
Eye problems: If you have glaucoma or cataracts or are at risk of developing them, have your eyes checked by your doctor before starting long-term treatment with this medication. Have your eyes monitored at regular intervals while using this medication.
Growth effects: Long-term use of corticosteroids, including inhaled forms such as this medication, may slow the growth of children and adolescents. It is important to use the lowest effective dose for managing asthma symptoms. Talk to your doctor if you have any concerns.
Infections: Corticosteroids such as beclomethasone may worsen existing infections, mask the signs of infection, and increase the risk of new infections, especially for people who are also taking medications that suppress the immune system (e.g., azathioprine, cancer medications, cyclosporine). If you use this medication for several months or longer, your doctor will monitor you periodically for signs of infection. If you have not had chicken pox or measles or have not been vaccinated against these infections, take special care to avoid exposure to them.
Medical conditions: If you have a thyroid disorder or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Oral hygiene: Adequate oral hygiene is very important in minimizing the overgrowth of microorganisms such as candidiasis (thrush). Proper oral hygiene includes rinsing your mouth with water after using the inhaler. Using a spacer device with the inhaler can greatly reduce how much medication stays in your mouth. Thrush infections, should they occur, may require treatment with appropriate antifungal therapy or the discontinuance of treatment with fluticasone, depending on the severity of the infections.
Steroid medication use: If you have taken or are still taking oral steroid medications over the last several months, consult with your doctor before using this medication. In times of stress or during a severe asthma attack, your doctor may want you to start your oral steroid medication again.
Stopping medication: Do not stop this medication abruptly, as this may cause your condition to get worse. When this medication is stopped, it should be stopped gradually as directed by your doctor.
Worsening of asthma: Increasing use of your bronchodilators (e.g., salbutamol) to control asthma symptoms is an indication that your asthma may be worsening. Sudden and progressive worsening in asthma control is potentially life-threatening, and consideration should be given to increasing the dose of fluticasone inhalation. Talk to your doctor or pharmacist to learn more about how to properly monitor for symptoms of worsening asthma.
Wheezing: This medication may cause the airways to spasm immediately after using the inhaler. If this happens, use your rescue inhaler as soon as possible to relieve the symptoms, then call your doctor as soon as possible.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking beclomethasone, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under 5 years or age. Side effects affecting behaviour and growth may be more likely to occur when this medication is used by children.
