Asthma Allergies And Covid
Throughout the pandemic, having asthma was considered a risk factor for severe COVID-19. But new data show that people with asthma are relatively protected from severe COVID-19, said Geoffrey Chupp, MD, professor of medicine in the Section of Pulmonary, Critical Care & Sleep Medicine at Yale School of Medicine .
We looked at 8,000 hospital admissions of patients with COVID-19, and we found that the patients who were diagnosed with asthma – about 10% of the patients – were more likely to survive compared to those people who didnt have asthma, Chupp said. He emphasized that the patients had asthma, not smoking-related lung diseases such as emphysema and COPD.
Its possible that some of the medications used for asthma helped to reduce the inflammation that COVID-19 causes, Chupp said. Its also likely that the type of immune response most asthmatics have, the allergic response, protected them from severe lung damage, he added.
However, after these patients recovered from COVID-19, their asthma became reactivated. As they healed, their natural immune response came back with more activity, explained Chupp. Were seeing a fair amount of post-COVID uncontrolled asthma. Most people do well but some have this persistence, a kind of long-hauler problem, although most of them will get better with time.

What Are The Potential Risks And Side Effects Of Drugs Used To Treat Asthma
Common side effects of short-acting asthma medications are a feeling of jitteriness, tremors, and/or heart palpitations. Hyperactivity can also occur, particularly in children.
The two most common side effects of inhaled corticosteroids are hoarseness or thrush, which is an overgrowth of yeast in the mouth. It is therefore recommended that patients using inhaled corticosteroids rinse their mouth after use. These side effects can also be minimized with proper inhaler technique. There is often concern about potential long-term side effects for inhaled corticosteroids. Numerous studies have repeatedly shown that even long-term use of inhaled corticosteroids has very few, if any, sustained significant side effects, including changes in bone health, decreased growth, or weight gain. However, the goal always remains to treat all individuals with the least amount of medication that is effective. Patients with asthma should be routinely reassessed for any appropriate changes to their medical regimen. Although uncommon, the combination asthma medications may also cause palpitations or a sense of jitteriness due to the long-acting beta-agonists.
Montelukast, the leukotriene modifier medication, may cause mood changes or sleep disturbance, particularly in children. Zileuton may cause liver inflammation, so health-care professionals should periodically monitor liver blood tests.
Risks Of Nebulizer Treatment
There are some side effects that may occur in certain individuals who use nebulizers. The most common side effects of nebulizer treatment are rapid heartbeat, jitteriness and anxiety. Less frequent side effects may include headache, nausea, vomiting or throat irritation. Serious reactions to nebulizer treatment are also possible and should be immediately reported to the prescribing physician. These dangerous symptoms may include chest pain, rash, hives, swelling or difficulty swallowing.

What Are Rescue Medications For Asthma
A rescue medication for asthma is a medication that works within minutes to open the airways and provides quick relief from asthma symptoms, such as chest tightness, shortness of breath, cough, or wheezing. The rescue medications for asthma include albuterol, levalbuterol , and ipratropium . Of these, albuterol is by far the most commonly prescribed rescue medication for asthma. Levalbuterol is the chemical mirror image of albuterol and may have less potential to make patients restless or jittery. Ipratropium has shown to be helpful when used along with albuterol in patients requiring emergency treatment for asthma. It also may be used in patients who are unable to tolerate albuterol or levalbuterol.
Many first-line controller and rescue medications are administered through asthma inhalers. Some of these inhalers are called metered-dose inhalers in which the inhaler itself propels the medication into the lungs. Other inhalers are activated by patients taking a breath, and these are called dry powder inhalers or breath-actuated inhalers. Different types of inhalers may work better for different individuals, but both types of inhalers are effective for asthma symptom control if used correctly.
Relievers For Adults And Children
Everyone who has asthma needs a reliever to use when they have asthma symptoms.
In Australia, most relievers are available from pharmacies without a prescription. Relievers should only be used when you or your child has symptoms and should not be over-used.
In preschool children, wheezing may not be asthma. Wheezing does not need to be treated if your child is still happy and active while wheezing and does not seem to be having any problem breathing. If it is hard for your child to breathe while wheezing , you must seek medical help immediately.

Before Taking This Medicine
You should not use Symbicort if you are allergic to budesonide or formoterol.
Budesonide can weaken your immune system. Tell your doctor about any illness or infection you’ve had within the past several weeks.
To make sure Symbicort is safe for you, tell your doctor if you have ever had:
-
a thyroid disorder; or
-
an electrolyte imbalance .
Tell your doctor if you are pregnant. It is not known whether budesonide or formoterol will harm an unborn baby. However, having untreated or uncontrolled asthma during pregnancy may cause complications such as low birth weight, premature birth, or eclampsia . The benefit of treating asthma may outweigh any risks to the baby.
It may not be safe to breastfeed while using Symbicort. Ask your doctor about any risk.
Symbicort is not approved for use by anyone younger than 6 years old.
Side Effects Of Steroids
Like all prescription drugs, there is a risk of side effects when you take steroids. But your GP will only ever prescribe them if the benefits outweigh the risks.
Its also worth remembering that youll be kept on the lowest possible dose of steroids to manage your asthma, which will help minimise the chances of having side effects.
Side effects from your steroid preventer inhaler
Inhaled steroids are usually in a very low dose and have few or no side effects. However, they can sometimes cause side effects like a sore throat or thrush.
Using your inhaler in the best way, with a spacer, and rinsing your mouth out, cuts your risk of side effects – the steroid medicine youre inhaling goes straight down into the airways and very little is absorbed into the rest of the body, says Dr Andy.;If youre taking a higher dose your GP or asthma nurse will keep a closer eye on you to monitor side effects.
Find out more about your preventer inhaler and possible side effects here.
Side effects from a short course of steroid tablets
Most people who take a short course of oral steroids wont experience significant side effects. Youre more likely to notice side effects if youre on a high dose.
Although the dose of steroid going into your body is higher if youre taking them in tablet form, any side effects like stomach upset, increased appetite, and mood swings are usually temporary and will stop once the course of tablets has finished.

Rescue Inhalers For Asthma Attacks
Rescue medicines do just what the name says: Work quickly enough to rescue you during an asthma attack. These drugs should be used for short periods of time for symptoms of asthma such as wheezing and cough. You may also hear these drugs called SABAs, which stands for short-acting beta-agonist.
Rescue inhalers work by relaxing the airway muscles. Used early, this can help keep an asthma attack from getting worse. These drugs begin to work in minutes, and the effects last for 4 to 6 hours. Examples of rescue inhalers include:1,2
- Accuneb, Digihaler , ProAir, Proventil, RespiClick, Ventolin HFA
- Xopenex HFA
How Should I Use Symbicort
Symbicort comes with a medication guide for safe and effective use, and directions for priming and cleaning the Symbicort inhaler device. Ask your doctor or pharmacist if you have any questions.
Follow all directions on your prescription label and read all medication guides. Use the medicine exactly as directed. Using too much of this medicine can cause life-threatening side effects.
If you also use an oral steroid medication, you should not stop using it suddenly. Follow your doctor’s instructions about tapering your dose.
Symbicort is not a rescue medicine for asthma or bronchospasm attacks. Use only fast-acting inhalation medicine for an attack. Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Do not allow a young child to use Symbicort without help from an adult.
Rinse your mouth with water after each use of your inhaler.
It may take up to 1 week before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.
Your dose needs may change if you have surgery, are ill, are under stress, or have recently had an asthma attack. Do not change your medication dose or schedule without your doctor’s advice.

When Will Your Doctor Prescribe Steroids For Your Asthma
Your doctor will prescribe steroids for your asthma if you need extra help with symptoms. Theyll prescribe the lowest dose of steroid medicines you need to treat your asthma symptoms and keep you well.
For example, your GP will prescribe steroid medicine if: ;
- youre taking your reliever inhaler three or more times a week. Most people with asthma are prescribed a steroid preventer inhaler to use every day. It stops inflammation building up in your airways and cuts your risk of symptoms. So, if youve only been given a reliever inhaler, and youre using it three or more times a week, see your GP.
- youve had an asthma attack. You might be given a short course of steroid tablets to take until your symptoms are fully under control. These can quickly get the swelling in your airways back down again if you have an asthma attack.
- youre getting asthma symptoms even when youre taking your preventer inhaler as prescribed. This is when a course of steroid tablets may be what you need to get your asthma back under control.
- you have severe asthma. Some people with severe asthma are prescribed a longer course of steroid tablets at higher doses.;
If your asthma is still not well controlled in spite of high dose inhaled steroids, keep taking them until you can discuss your treatment with your GP. Use our severe asthma tool to find out if you need a referral to a severe asthma specialist.
Asthma Medications And Treatment
When it comes to understanding all of the asthma treatments available, its natural to feel a little bit confused.
The important thing to remember is that asthma is a variable disease. In other words, asthma symptoms, severity and treatment plans can vary from person to person, and even the same persons condition may fluctuate throughout the year.
The two most common types of asthma medications are controllers which treat the long-term, underlying inflammation in your airways and relieverswhich act as your rescue inhaler and provide fast but short-term relief of symptoms. You should speak with your healthcare professionalabout finding a treatment plan that is right for you.

How To Use A Nebulizer Without Medication
Water in a nebulizer for cough, stuffy nose, lung congestion, and bronchitis is many times recommended to use, especially for people who do not want to use medications for respiratory problems.
For operating your nebulizer without medicines you need to add salt water solution or saline water into the medicine cup.
Inhalation of sodium chloride solution actually helps in breaking down the deposited mucus and phlegm in the lungs which are then expelled out as cough easily.
Is Saline for Baby Asthma Cough Safe?
As the saline solution is just a sterile salt water solution and not an actual asthma medication, using it to nebulize the baby is completely safe and free of side effects.
However saline nebulizer for infants should be given after consulting with the pediatrician who can advice the best saline nebuliser dose that can be given for your baby safely without showing any side effects.
Care that if there are signs of acute wheezing and severe asthma seen, nebulizing just with hypertonic saline may not prove much effective.
In this case, you may need to use asthma medications for getting a faster cure.
Where Can I Buy Saline Solution For Nebulizer?
Saline for nebulizer is easily available over the counter at online shopping sites like Amazon.
Care that you buy sterile saline from these stores and not use the homemade saline solution in the nebulizer machine as this can be risky.

What Are Monoclonal Antibodies For Asthma
Omalizumab is one of the newer asthma medications. It may be considered for individuals with persistent, moderate to severe asthma due to seasonal allergies that is not controlled by inhaled corticosteroids. The cost of omalizumab is estimated at $12,000-$15,000 per year.
Mepolizumab is another monoclonal antibody that is also used for moderate to severe asthma not controlled with standard care, including inhaled steroids.
How monoclonal antibodies work
Omalizumab binds to human immunoglobulin E on the surface of mast cells and basophils . By binding to IgE, omalizumab reduces the release of the allergy-inciting chemicals.
Mepolizumab binds to interleukin 5, which results in a decrease certain inflammatory cells . These eosinophils contribute to the development of asthma attacks.
Who should not use these medications
Individuals who are allergic to omalizumab or mepolizumab or its contents should not use it.
Use
For omalizumab, the dose depends on the IgE levels in the blood.
Adults and children older than 12 years of age are given an injection every two to four weeks.
For mepolizumab, adults and children older than 12 years of age who have elevated eosinophils receive 100 mg by injection every four weeks.
