Understanding Asthma Medications

Do you struggle with asthma symptoms that hold you back? Living with frequent breathing problems can make you feel tired and scared. It is hard to enjoy your day when you worry about flare-ups. 

You may find that each day feels like a challenge with tight airways and constant discomfort. This is the problem many face. 

There are medications that offer a solution to help you breathe easier and feel more secure. In this article, you will learn how these medicines fit into your asthma care plan and greatly improve your quality of life.

🔑 Key Takeaways ➤ Inhaled corticosteroids stand as a main treatment for your asthma. They reduce swelling and help you avoid attacks. ➤ LABAs relax your airway muscles and work well with inhaled corticosteroids. They ease your breathing for many hours. ➤ Leukotriene modifiers and LAMAs block chemicals and muscle contractions. They add extra help when your usual treatment falls short. ➤ Quick-relief medications act fast during an attack. They work in minutes to open your airways. Some treatments, like theophylline and oral corticosteroids, need careful monitoring. Your doctor keeps a close watch on their risks. ➤ Proper inhaler and nebulizer use matters. You get more medicine in your lungs and fewer side effects when you use them correctly. ➤ Allergy medications and biologics treat triggers and severe asthma. They target specific cells and proteins to reduce flare-ups.

Long-Term Control Medications

Long-term control medications help you manage asthma over time. They work to reduce inflammation and keep your airways open so you breathe easier. Some drugs, like inhaled corticosteroids, target the swelling in your lungs, while others, such as leukotriene modifiers and LABAs, work by relaxing your muscles or blocking certain chemicals. A few options, like LAMAs and theophylline, add extra help when your usual treatment isn’t enough. 

Read on to learn how each medication fits into your overall asthma care plan.

1. Inhaled Corticosteroids (ICS)

Inhaled Corticosteroids (ICS) are a cornerstone of long-term asthma control. They reduce inflammation and swelling in your airways, so you breathe easier over time. They directly target airway inflammation, but you may need several months to see the full benefit. Daily use helps keep asthma attacks and complications at bay.

The medications in this class include:

• Fluticasone Propionate (Flovent HFA, Flovent Diskus)
• Fluticasone Furoate (Arnuity Ellipta)
• Budesonide (Pulmicort Flexhaler, Pulmicort Respules)
• Mometasone Furoate (Asmanex Twisthaler, Asmanex HFA)
• Beclomethasone Dipropionate (Qvar RediHaler)
• Ciclesonide (Alvesco)
• Flunisolide (Aerospan)

However, research shows that long-term ICS use may have some systemic risks. According to a systematic review, some studies reported a 5% increase in the odds of developing cataracts. Four observational studies found that ICS users had a higher risk of pneumonia. Some data even suggest a 50% rise in the odds of tuberculosis or other mycobacterial infections. Three out of six studies noted a decrease in bone mineral density, which could raise the risk of fractures.

An overview in the Open Respiratory Medicine Journal adds that fluticasone is more likely to cause these systemic effects compared to budesonide. It also points out that newer molecules like ciclesonide may lower this risk. Clinicians aim to use the lowest effective dose to reduce side effects, and you should talk to your doctor if you have concerns about these risks.

These findings do not change the fact that ICS are a key treatment for asthma. They help manage your symptoms and prevent flare-ups. At the same time, knowing the risks helps you and your doctor make the best choices for your care.

🩺 Doctor’s Note If you use a metered-dose inhaler (MDI), remember to rinse your mouth after each use. This step cuts down on leftover medicine and side effects like throat irritation or oral yeast infections. Although you might not see an immediate change, these drugs remain the most effective long-term option for controlling chronic asthma symptoms.

2. Leukotriene Modifiers

Leukotriene Modifiers block leukotrienes. These chemicals come from your immune system and cause inflammation and airway tightening. In other words, these medications keep your airways open. They interrupt the chain reaction that causes tightening. The drugs in this category include:

• Montelukast (Singulair)
• Zafirlukast (Accolate)
• Zileuton (Zyflo, Zyflo CR)
• Pranlukast (Onon)

These drugs help prevent breathing problems from allergies, asthma and even chronic obstructive pulmonary disease. They work when you take them as a tablet once a day.

They reduce asthma symptoms over 24 hours. But you should know about potential side effects. For instance, Montelukast may rarely cause psychological reactions such as agitation, depression, or suicidal thoughts. On March 4, 2020, the FDA strengthened warnings about Montelukast. The FDA now requires a Boxed Warning on Montelukast because reports show it may lead to:

• Aggressive behavior
• Bad or vivid dreams
• Memory problem
• Suicidal thoughts

Notify your doctor if you notice any changes.

3. Long-Acting Beta Agonists (LABAs)

Long-Acting Beta Agonists (LABAs) relax your airway muscles for at least 12 hours. They help keep your airways open and ease your breathing over a long period. This makes them a key part of long-term asthma management. LABAs work by relaxing the smooth muscles around your airways, which reduces your symptoms. These medications include:

• Salmeterol (Serevent Diskus)
• Formoterol (Foradil, Oxeze, Perforomist)
• Arformoterol (Brovana)
• Indacaterol (Arcapta Neohaler, Onbrez Breezhaler)
• Olodaterol (Striverdi Respimat)
• Vilanterol (available only in combination products)

You should always use LABAs with an inhaled corticosteroid. Using LABAs alone has been linked to severe asthma attacks. According to a study, combining a LABA with an inhaled corticosteroid is a logical choice. Corticosteroids reduce inflammation and lower airway hyperresponsiveness. LABAs also help by stopping the release of chemicals from mast cells. 

This means that the two medicines support each other to control your asthma better without extra side effects.

4. Long-Acting Muscarinic Antagonists (LAMAs)

Long-Acting Muscarinic Antagonists (LAMAs) work by opening your airways. They block muscarinic receptors that normally cause your airways to tighten, so you can breathe easier. These medication include:

• Tiotropium (Spiriva Respimat, Spiriva HandiHaler)
• Umeclidinium (Incruse Ellipta)
• Aclidinium (Tudorza Pressair)
• Glycopyrrolate (Seebri Neohaler, Lonhala Magnair)
• Revefenacin (Yupelri)

A LAMA may be used when LABAs alone are not enough to control your asthma. LABAs work by relaxing the airway muscles, but sometimes that isn’t sufficient for full symptom control. 

In these cases, adding a LAMA like tiotropium can further open your airways by blocking acetylcholine receptors that cause muscle contraction. This extra effect helps reduce bronchoconstriction and lowers the risk of asthma exacerbations.

One study showed that tiotropium, when added to inhaled corticosteroids and LABA therapy, improved lung function and reduced asthma worsening. The study supports the use of LAMAs as an effective add-on treatment, especially for patients who still experience symptoms despite using LABAs and ICS. The Global Initiative for Asthma now includes tiotropium as an option for patients at higher treatment steps who have a history of exacerbations.

✂️ In Simple Terms if your current long-acting treatment isn’t enough, a LAMA can provide extra help to keep your airways open and improve your breathing.

5. Theophylline

Theophylline acts as a bronchodilator in pill form to relax your airway muscles. It opens your airways through muscle relaxation so you can breathe easier. Theophylline is available under several brand names, including:

• Theo-24
• Theochron
• Elixophyllin
• Uniphyl
• Quibron-T
• Slo-Bid
• Theolair

However, its use has declined. Theophylline has a narrow therapeutic window and requires regular blood tests to monitor your dose. 

Doctors aim for a serum concentration of 10 to 20 mcg/mL in adults, and levels above 20 mg/L can lead to side effects like nausea, headache, or even seizures. Doctors often choose other treatments that have more predictable dosing and fewer monitoring needs. Regular blood tests help keep your dose safe and prevent side effects from improper dosing.

6. Oral Corticosteroids

Oral corticosteroids reduce systemic inflammation during severe asthma attacks or when other medications aren’t enough. They work by calming widespread inflammation that inhaled therapies alone cannot manage, which is why you rely on them during acute episodes. Common examples include:

• Prednisone (Deltasone, Rayos)
• Prednisolone (Orapred, Millipred)
• Methylprednisolone (Medrol, Solu-Medrol)
• Dexamethasone (Decadron, DexPak)

These drugs work by suppressing your immune system and easing inflammation. They help relieve symptoms, but they also affect your entire system. That is why you might notice side effects such as swelling in your lower legs, high blood pressure, or mood swings even after a short course. With long-term use, risks increase. 

For example, you could develop cataracts, weight gain, osteoporosis, or muscle weakness. Doctors use these drugs sparingly and usually for a limited time to keep those risks low.

To minimize side effects, your doctor may adjust the dose or switch to other forms, like inhaled corticosteroids. They also monitor you closely if you need them for a longer period. This careful approach helps balance the benefits of controlling severe asthma with the potential risks.

7. Inhaled Mast Cell Stabilizers

Inhaled Mast Cell Stabilizers offer an extra option for asthma management and help keep your airways clear. They work by stabilizing mast cells so that when you face allergens, the cells do not release inflammatory chemicals like histamine and leukotrienes. A key example is Cromolyn. 

Cromolyn sodium comes from a natural herb called Ammi visnaga and prevents these chemicals from causing airway swelling. Its effect lasts about 6 hours after each dose, so you get extra protection throughout the day. 

These medications work well with your other long-term treatments, and they lower your risk of an asthma attack.

Quick-Relief (Rescue) Medications

Quick-relief medications for asthma help you breathe easier when asthma symptoms strike. They work fast to open your airways so you can catch your breath. These drugs are meant for those moments when you need help right away.

1. Short-Acting Beta Agonists (SABAs)

Short-Acting Beta Agonists (SABAs) work fast to relax your airway muscles, giving you quick relief during an asthma attack. SABAs are your “rescue” inhalers. 

Here are the common SABAs along with their brand names and usual dosages:

Generic Name	Brand Name(s)	Usual Dosage
Albuterol/Budesonide	Airsupra	2 puffs as needed for asthma symptoms, not to exceed 12 puffs in a 24-hour period.
Albuterol Sulfate	ProAir RespiClick	2 puffs every 4–6 hours as needed.
	ProAir HFA	1 or 2 inhalations every 4–6 hours for quick relief; 2 puffs 15 minutes before exercise.
	Proventil HFA	1 or 2 inhalations every 4–6 hours as needed.
	Ventolin HFA	1 or 2 inhalations every 4–6 hours as needed.
Albuterol Sulfate HFA	Generic Albuterol HFA	1 or 2 inhalations every 4–6 hours as needed.
Albuterol Sulfate	Generic (0.083% solution)	One unit dose vial every 4–6 hours via nebulizer.
	AccuNeb	0.63 mg or 1.25 mg in 3 mL unit-dose vials every 4–6 hours via nebulizer for ages 2–12.
Levalbuterol HCl	Xopenex Inhalation Solution	One vial (0.31 mg, 0.63 mg, or 1.25 mg) every 6–8 hours via nebulizer for ages 6 and above.
	Xopenex HFA	2 inhalations repeated every 4–6 hours for ages 4 and above.

If you use your SABA more than two days a week, it means your asthma may not be well controlled. So, keep track of your inhaler use and talk with your doctor about adjusting your treatment plan if needed.

2. Anticholinergics

Anticholinergics work to reduce mucus production and help open your airways. They ease your breathing by keeping your airways clear. 

Here are the common anticholinergic medications, their brand names, and usual dosages:

Generic Name	Brand Name(s)	Usual Dosage
Aclidinium Bromide (400 mcg)	Tudorza Pressair	For COPD in adults: 1 puff twice daily.
Glycopyrrolate	Seebri Neohaler	Maintenance treatment of COPD: 1 dose twice daily.
Ipratropium Bromide/Albuterol	Combivent Respimat	For relief of bronchospasm in COPD: 1 puff four times daily.
Ipratropium Bromide HFA	Atrovent HFA	For relief of bronchospasm in COPD (age 12 and above): 2 inhalations every 6 hours.
Revefenacin	Yupelri	Maintenance treatment of COPD in adults (18 and above): 1 vial per day via nebulizer.
Tiotropium (1.25 mcg)	Spiriva Respimat	Maintenance treatment of asthma (age 6 and above): 2 puffs (2.5 mcg) daily.
Tiotropium Bromide Inhalation Powder	Spiriva HandiHaler	For long-term relief of bronchospasm in COPD (adults): One capsule once daily with HandiHaler.
Umeclidinium	Incruse Ellipta	COPD maintenance treatment in adults: 1 puff daily.

One review on anticholinergics in acute asthma found that giving multiple doses of ipratropium bromide in the emergency department reduced hospital admissions by 30% to 60%. In other words, in cases of severe asthma, adding ipratropium to a beta2-agonist can boost lung function and lower the chance of needing hospitalization.

Anticholinergics can be a strong part of your asthma treatment plan. Your doctor might choose one method or the other to help keep your airways open for easier breathing.

3. Combination Quick-Relief Medications

Combination Quick-Relief Medications combine a SABA and an anticholinergic for enhanced rapid relief. They work quickly when you need fast help during an asthma attack. 

For example, Ipratropium and Albuterol (Combivent) merge the immediate bronchodilation from a SABA with the extra benefit of an anticholinergic that cuts down on mucus production and opens your airways even more. With both medicines working together, you get a more complete response when symptoms hit.

One study found that adding ipratropium to albuterol and corticosteroid therapy lowered hospitalization rates in children with asthma. In children with severe asthma, the hospitalization rate dropped from 52.6% to 37.5% when ipratropium was added. This means that about 7 children (or more precisely, 6.6) with severe asthma need to be treated with the combination to prevent one hospitalization. 

Medications for Allergy-Induced Asthma

Medications for allergy-induced asthma help you manage allergies that can make your asthma worse. They work by lowering your immune system’s overreaction and easing allergy symptoms. 

Some treatments gradually change how your body responds to allergens, while others directly control symptoms like a runny nose or congestion.

1. Immunotherapy

Immunotherapy offers a long-term way to reduce your allergic reactions and help control asthma. 

Allergy Shots

With allergy shots (subcutaneous immunotherapy), you start with skin tests to pinpoint which allergens trigger your symptoms. Then, you receive regular injections—weekly at first, then monthly—over 3 to 5 years. This gradual process makes your immune system less reactive over time. 

According to a systematic review, these shots can reduce the use of long-term control medications and may even improve your lung function and quality of life. Local and systemic allergic reactions are common but rarely force a change in treatment.

Sublingual Immunotherapy Tablets

Another option is sublingual immunotherapy tablets (SLIT). These tablets dissolve under your tongue and deliver tiny doses of allergens daily. They work well for patients triggered by specific allergens such as:

• Grass
• Ragweed
• Dust mites

In fact, one large trial showed that children taking a daily grass tablet had fewer asthma symptoms and needed less asthma medication over time. This treatment helps lower your allergic responses and can reduce the frequency and severity of asthma attacks.

Here are the common SLIT allergy tablets, their brand names, uses, and usual dosages:

Generic Name	Brand Name	Use	Usual Dosage
Dust mite oral extract	Odactra	Dust mite allergy (ages 18-65)	One tablet daily, year-round. The first dose should be taken in a doctor’s office to monitor for any adverse reactions.
Timothy grass pollen sublingual extract	Grastek	Allergy to timothy and related grasses	One tablet daily, starting 12 weeks before the grass pollen season. The first dose should be taken in a doctor’s office.
Grass pollen sublingual extract	Oralair	Allergic rhinitis with or without conjunctivitis (ages 10-65)	One tablet daily, starting at least 4 months before the grass pollen season. The first dose should be taken in a doctor’s office.
Short ragweed pollen sublingual extract	Ragwitek	Allergy to ragweed	One tablet daily, starting 12 weeks before the ragweed pollen season. The first dose should be taken in a doctor’s office.

2. Allergy Medications

Allergy Medications help control symptoms that can trigger asthma attacks. They manage signs like a runny nose, itching, and congestion, which can worsen your asthma by causing airway inflammation. These drugs work to stop the cascade of reactions that might lead to an attack.

They include:

• Oral and nasal antihistamines
• Decongestants
• Nasal corticosteroid sprays and cromolyn nasal sprays

These medications keep your allergy symptoms in check. This, in turn, helps prevent asthma attacks. 

Biologic Therapies

Biologic Therapies are advanced medications for severe asthma. They target specific cells or proteins to reduce lung inflammation. These treatments work at a cellular level and are used when standard options do not provide adequate control.

1. Anti-IgE Biologics

One key category is Anti-IgE Biologics. For example, Omalizumab (Xolair) blocks IgE antibodies that trigger allergic reactions. It works by binding to IgE at the C-epsilon-3 site, so it stops these antibodies from attaching to receptors on mast cells, basophils, and eosinophils. This action minimizes the allergic cascade that can worsen your asthma symptoms.

Omalizumab is a recombinant humanized IgG1 monoclonal antibody approved by the FDA in 2003 for moderate-to-severe asthma and later for chronic spontaneous urticaria. It lowers free IgE levels and reduces the need for other medications. 

✂️ In Simple Terms By blocking IgE, Omalizumab helps keep allergic reactions in check, so your airways stay less inflamed and you can breathe easier.

2. Eosinophil Reduction Biologics

Eosinophil Reduction Biologics lower the number of eosinophils, a type of white blood cell that causes inflammation. They work by targeting specific inflammatory pathways to reduce the frequency of asthma exacerbations. For example:

• Benralizumab (Fasenra)
• Dupilumab (Dupixent)
• Mepolizumab (Nucala)
• Reslizumab (Cinqair)

These drugs reduce the exacerbation rate in patients with high blood eosinophil counts. 

Mepolizumab and benralizumab also have steroid-sparing effects, which means they can lower the need for oral corticosteroids. Reslizumab is unique because it is given intravenously instead of by injection under the skin. Meanwhile, Dupilumab targets the IL-4 receptor and helps reduce both exacerbations and the use of oral corticosteroids, and it works for nasal polyposis and atopic dermatitis too.

Although many patients with severe asthma may qualify for more than one of these biologics, head-to-head trials are still lacking. 

Therefore, the choice of therapy depends on individual patient characteristics and preferences, such as dosing frequency and the presence of comorbidities. All of these biologics have shown excellent safety profiles so far, so you and your doctor can work together to find the best option for your needs.

3. TSLP Blockers

TSLP Blockers offer another approach to reducing lung inflammation. They work by targeting thymic stromal lymphopoietin (TSLP), a key cytokine that kicks off the inflammatory cascade. 

For example, Tezepelumab-ekko (Tezspire) binds to TSLP and prevents it from triggering cytokine release, which in turn reduces inflammation in your lungs.

A 2024 review explains that Tezepelumab was approved in Japan in September 2022 for severe or refractory asthma when other treatments fail. In the Phase 3 NAVIGATOR trial, patients with uncontrolled, severe asthma received Tezepelumab every 4 weeks over 52 weeks, and they experienced a significant reduction in annual asthma exacerbations. Their lung function improved, quality of life got better, and levels of inflammatory biomarkers decreased. These results were seen regardless of baseline biomarker levels.

These therapies are usually given as injections every 2 to 8 weeks, so your doctor will choose the best schedule for you. However, they require careful monitoring for side effects, and regular check-ups help ensure that the treatment remains effective while any adverse effects are managed promptly.

Delivery Methods and Devices

1. Inhalers

Inhalers deliver your asthma medication straight to your lungs. They are one of the most common and effective ways to manage your symptoms. There are several types, and each is designed for different needs.

1. Metered-Dose Inhalers (MDIs) use a pressurized canister to deliver a quick, concentrated burst of medication for fast relief. 
2. Dry Powder Inhalers (DPIs) release medicine as a fine powder when you take a deep breath. 
3. Breath-Actuated Inhalers release medicine automatically as you inhale, so you get the proper dose without much effort. Slow-Moving Mist Inhalers create a gentle mist that helps more medicine reach your lungs instead of sticking in your mouth.

You can also attach a spacer or holding chamber to an MDI. This device captures the medicine so you can breathe it in slowly and at your own pace. Doing so helps maximize the amount of medicine that reaches your airways and reduces side effects like throat irritation.

However, many people have trouble using MDIs correctly. One study found that about 87% of patients made at least one error when using their inhaler. Nearly 77% of patients did 20% or more of the steps incorrectly. The most common mistakes were not exhaling fully before inhaling (65.5%), not holding their breath for 5 to 10 seconds (41.9%), and not inhaling slowly and deeply (39.4%). Other errors include not exhaling after inhaling (35.9%) and not shaking the inhaler before use (34.2%). These errors can lower the amount of medicine that gets into your lungs.

Other research shows that how you feel about your inhaler also matters. Patients who find their device easy to use tend to stick with their treatment better. Your own preference and proper training can make a big difference in how well you manage your asthma.

If you have any trouble using your inhaler, ask your healthcare provider for a demonstration. Learning the correct technique will help you get the most benefit from your medicine and keep your symptoms under control.

2. Nebulizers

Nebulizers are devices that turn liquid medication into a fine mist you breathe in through a mask or mouthpiece. They help the medicine reach deep into your lungs so it works well. They are especially great for:

• Infants
• Small children
• Older adults
• Anyone who struggles with coordinating their breath using standard inhalers

By turning liquid into a mist, nebulizers help you get the right dose easily. 

A recent observational study called the CARE study looked at how children with asthma in China used home nebulizer therapy. It found that most children followed their treatment well—about 70% adherence by electronic monitoring—and their asthma control improved significantly over 12 weeks. This shows that when used correctly, nebulizers can be very effective in managing asthma in children.

Guidelines also recommend using efficient nebulizer systems because they deliver a better dose of medicine to your lungs. In other words, nebulizers can be a practical choice if you have difficulty using an inhaler, ensuring you get the medicine you need to keep your breathing steady.

3. Patient education on delivery

Patient education on delivery is key to managing asthma. You need to know the right technique for using your device—whether it’s an inhaler, spacer, or nebulizer—to ensure you get the correct dose and that the medication reaches your airways effectively. 

When you learn and use the proper method, you not only gain the maximum benefit from your medicine but also reduce side effects, leading to better overall asthma control.

A study published in the Jornal Brasileiro de Pneumologia (2016) evaluated the impact of educational interventions on inhaler technique in patients with asthma and COPD. 

In this trial, 44 patients were re-evaluated after receiving hands-on training on proper inhaler use. The results showed a significant decrease in the number of technique errors—by about 0.7 errors on average—with marked improvements specifically in exhalation before inhalation and in holding their breath after taking the dose. 

In asthma patients, these improvements were accompanied by significant gains in lung function parameters, as well as better scores on clinical control tests like the CARAT. This evidence suggests that when patients receive proper education on how to use their inhalation devices, they can achieve improved symptom control and lung function.

Final Words

Take control of your breathing today. Speak with your doctor and ask for a review of your treatment plan. Check your inhaler technique and know your medications well. 

Set clear health goals and track your progress. Ask questions and share your concerns with trusted experts.

FAQs on Medicine for Asthma Relief

What is the difference between long-term control and quick-relief medications?

Long-term control medications are taken daily to prevent symptoms. Quick-relief medications act fast during an attack but last only a few hours. If you need your rescue inhaler too often, talk with your doctor.

How do inhaled corticosteroids work?

They reduce inflammation and lessen airway swelling. You must use them daily for several months to see full benefits. They may cause a sore throat, so rinse your mouth after use.

What are quick-relief medications?

Quick-relief meds, like albuterol, relax your airway muscles fast, allowing your airway to open up. They help during sudden attacks but are not for daily use. Use them only when needed and consult your doctor if you use them too often.

What are leukotriene modifiers and when are they used?

They block chemicals called leukotrienes that cause inflammation. You take them as pills every day. They work well for mild asthma or exercise-induced symptoms, but watch for mood changes.

How do I know if my asthma is under control?

If you rarely use your rescue inhaler and have few symptoms at night, your asthma is likely under control. If you use your inhaler more than twice a week, you should check with your doctor.

Can asthma medications cause side effects?

Yes, they can. Inhaled corticosteroids might cause a sore throat, and quick-relief meds can cause jitteriness or a fast heartbeat. If side effects bother you, talk with your doctor.

What should I do if I need my rescue inhaler too often?

If you use your rescue inhaler more than twice a week, your asthma may not be well controlled. You should contact your doctor to review and adjust your treatment plan.
