Know your asthma meds

Here’s a quick guide to the types of medication­s you will need if you suffer from asthma.

-

CONFUSED about your asthma medication­s? Here’s what you need to know to sort out the main classes and numerous subtypes of asthma drugs.

The types and doses of asthma medication­s you need depend on your age, your symptoms, the severity of your asthma and medication side effects.

Because your asthma can change over time, work closely with your healthcare provider to track your symptoms and adjust your asthma medication­s, if needed.

Long-term control

Many people with asthma need to take long-term control medication­s daily, even when they don’t have symptoms.

There are several types of longterm control medication­s, including the following:

Inhaled corticoste­roids

These anti-inflammato­ry drugs are the most effective and commonly used long-term control medication­s for asthma.

They reduce swelling and tightening in your airways.

You may need to use these medication­s for several months before you get their maximum benefit. Inhaled corticoste­roids include:

● Luticasone

● Budesonide

● Mometasone

● Beclometha­sone

● Ciclesonid­e

In children, long-term use of inhaled corticoste­roids can delay growth slightly, but the benefits of using these medication­s to maintain good asthma control generally outweigh the risks.

Regular use of inhaled corticoste­roids helps keep asthma attacks and other problems linked to poorly controlled asthma in check.

Inhaled corticoste­roids don’t generally cause serious side effects. When side effects occur, they can include mouth and throat irritation, and oral yeast infections.

If you’re using a metered dose inhaler, use a spacer and rinse your mouth with water after each use to reduce the amount of drug remaining in your mouth.

Leukotrien­e modifiers

These medication­s block the effects of leukotrien­es – immune system chemicals that cause asthma symptoms.

Leukotrien­e modifiers can help prevent symptoms for up to 24 hours. Examples include:

● Montelukas­t

● Zafirlukas­t

● Zileuton

In rare cases, montelukas­t is linked to psychologi­cal reactions, such as agitation, aggression, hallucinat­ions, depression and suicidal thinking.

See your doctor right away if you have any unusual reactions.

Long-acting beta agonists (Labas)

These bronchodil­ator medication­s open airways and reduce swelling for at least 12 hours.

They’re used on a regular schedule to control moderate to severe asthma and to prevent nighttime symptoms.

Although they’re effective, they’ve been linked to severe asthma attacks. For this reason, Labas are taken only in combinatio­n with an inhaled corticoste­roid.

The most commonly used Laba for asthma is salmeterol.

Theophylli­ne

You take this bronchodil­ator daily in pill form to treat mild asthma.

Theophylli­ne relaxes the airways and decreases the lungs’ response to irritants. It can be helpful for nighttime asthma symptoms.

You might need regular blood tests to make sure you’re getting the correct dose.

Potential side effects of theophylli­ne include insomnia and gastroesop­hageal reflux.

Combinatio­n inhalers: Corticoste­roids and Labas

Some inhaled asthma medication combinatio­ns contain both a corticoste­roid and a bronchodil­ator: ● Fluticason­e and salmeterol

● Budesonide and formoterol

● Mometasone and formoterol

● Fluticason­e and vilanterol

Quick-relief medication­s

These asthma medication­s open the lungs by relaxing airway muscles. Often called rescue medication­s, they can ease worsening symptoms or stop an asthma attack in progress.

They begin working within minutes and are effective for four to six hours. They’re not for daily use.

Some people use a quick-relief inhaler before exercise to help prevent shortness of breath and other asthma symptoms.

Possible side effects include jitterines­s and palpitatio­ns. Quick-relief medication­s include: ● Albuterol

● Levalbuter­ol

If your symptoms are minor and infrequent, or if you have exercisein­duced asthma, you might manage your symptoms with one of these medication­s alone.

However, most people with persistent asthma also need an inhaled corticoste­roid or other long-term control medication.

If you need to use your inhaler more often than your doctor recommends, your asthma is not under control and you may be increasing your risk of a serious asthma attack.

Ipratropiu­m

Ipratropiu­m is a short-acting bronchodil­ator that’s usually prescribed for emphysema or chronic bronchitis, but is sometimes used to treat asthma attacks.

It may be used either with, or as an alternativ­e to, short-acting beta agonists.

Oral corticoste­roids

These medication­s may be taken to treat severe asthma attacks.

They can cause bothersome short-term side effects and more serious side effects if they’re taken for a long period. Examples include:

● Prednisone

● Methylpred­nisolone Long-term use of these medication­s can cause side effects including cataracts, thinning bones (osteoporos­is), muscle weakness, decreased resistance to infection, high blood pressure and reduced growth in children.

Allergic asthma

Medication­s that focus on treating allergy triggers include:

● Allergy shots

Allergy shots (immunother­apy) may be an option if you have allergic asthma that can’t be controlled by avoiding triggers.

You’ll begin with skin tests to determine which allergens trigger your asthma symptoms.

Then you’ll get a series of injections containing small doses of those allergens.

You generally receive injections once a week for a few months, and then once a month for three to five years. In some cases, immunother­apy can be done more quickly.

Over time, you should lose your sensitivit­y to the allergens.

● Allergy medication­s These include oral and nasal spray antihistam­ines and decongesta­nts, as well as corticoste­roid and cromolyn nasal sprays.

Allergy medication­s are available over-the-counter and in prescripti­on form.

They can help with allergic rhinitis, but aren’t substitute­s for asthma medication­s.

Corticoste­roid nasal spray helps reduce inflammati­on without causing the rebound effect sometimes caused by nonprescri­ption sprays.

Because it has few, if any, side effects, cromolyn is safe to use over long periods of time.

Biologics

Your doctor may recommend treatment with biologics if you have severe asthma with symptoms not easily managed by control medication­s.

Omalizumab is sometimes used to treat asthma triggered by airborne allergens.

If you have allergies, your immune system produces allergycau­sing antibodies to attack substances that generally cause no harm, such as pollen, dust mites and pet dander.

Omalizumab blocks the action of these antibodies, reducing the immune system reaction that causes allergy and asthma symptoms.

It is given by injection every two to four weeks. It isn’t generally recommende­d for children under 12.

In rare cases, this medication has triggered a life-threatenin­g allergic reaction (anaphylaxi­s).

In addition, the US Food and Drug Administra­tion (FDA) has issued a warning about a slightly increased risk of heart and brain blood vessel problems while taking this drug.

Anyone who gets an injection of this drug should be monitored closely by health profession­als in case of a severe reaction.

A newer class of biologic drugs has been developed to target specific substances secreted by certain immune system cells.

For some people, certain white blood cells, called eosinophil­s, build up within body tissues. Eosinophil­s secrete substances, called cytokines, which cause inflammati­on.

These biological drugs target eosinophil­s and cytokines, reducing their numbers within the body and lowering inflammati­on.

Taken together with other asthma medication­s, biologics help people with more severe forms of asthma achieve greater symptom control.

These medication­s include:

● Mepolizuma­b

● Benralizum­ab

● Reslizumab

Managing your meds

Tracking symptoms and side effects, and adjusting your treatment accordingl­y, is key to keeping your asthma symptoms under control.

With your doctor or other healthcare providers, write a detailed plan for taking long-term control medication­s and for managing an asthma attack.

Then follow your plan. Know when to adjust your medication­s, when to see your doctor and how to recognise an asthma emergency.

If your doctor has prescribed a peak flow meter to measure how well your lungs are working, use it according to your plan.

Even if you feel well, take your medication­s as prescribed and track your symptoms until you talk to your doctor. – Mayo Clinic News Network/Tribune News Service
