Proper Inhaler Technique

Proper Inhaler Technique - Brooklyn Allergy Dr.

Studies show that many patients are using their inhalers incorrectly, resulting in only 7%-40% of the medication being delivered to the lungs. Improper technique can result in poor asthma control resulting in stronger medications prescribed. Below are the steps for proper technique when using your metered-dose inhaler (i.e. ProAir, Proventil, Ventolin, Flovent …)

Take off cap. Shake the inhaler. Prime (spray or pump) the inhaler as needed according to manufacturer’s instructions (each brand is different).If you use a spacer or valved holding chamber (VHC), remove the cap and look into the mouthpiece to make sure nothing is in it. Place the inhaler in the rubber ring on the end of the spacer/VHC.Stand up or sit up straight.Take a deep breath in. Tilt head back slightly and blow out completely to empty your lungs.Place the mouthpiece of the inhaler or spacer/VHC in your mouth and close your lips around it to form a tight seal.As you start to breathe in, press down firmly on the top of the medicine canister to release one “puff” of medicine. Breathe in slowly (gently) and as deeply as you can for 3 to 5 seconds.Hold your breath and count to 10.Take the inhaler or spacer/VHC out of your mouth. Breathe out slowly.If you are supposed to take 2 puffs of medicine per dose, wait 1 minute and repeat steps 3 through 8.If using an inhaled corticosteroid, rinse out your mouth with water and spit it out. Rinsing will help to prevent an infection in the mouth.

Managing Asthma in the Winter

For many patients with asthma, cold weather can worsen their symptoms. This is due to the cold dry air outdoors and increased exposure to indoor allergens, such as mold, dust, and pet dander. Below are some tips to limit the effects of the cold weather on your asthma:

·Get your flu shot!

o   The effects of the flu can be more serious in asthmatic patients. Protect yourself by receiving the flu vaccine.

·Limit your risk of getting a cold

o   Wash your hands regularly and stay away from people that are sick.

·Add warmth and moisture to the air you breathe

o   Cold air is dry. Breathing dry air depletes the natural fluid that is found in the body’s airways. Dry airways become swollen and irritated which can worsen asthma symptoms. Breathe through your nose so that your nasal passages may warm and humidify the air before it gets to your lungs. Another way to do this is to wrap your scarf around your nose and mouth.

·Minimize your exposure to indoor allergens

o   Dust and vacuum your home regularly, eradicate all traces of mold, and place a HEPA air filter in common areas and bedrooms.

Managing Eczema in the Winter


During the winter months, the cold dry air outdoors and heating indoors deplete the skin of its moisture, which for many, worsens their eczema. Here are some tips on how to control eczema flares and reduce the need for topical steroids:

Use fragrance-free and additive-free products for all aspects of skin care. These can irritate the skin and worsen eczema.Frequently apply thick lotions or emollient moisturizers throughout the day. Emollient moisturizers are preferred because they create a barrier on the surface of the skin and prevent moisture loss. Moisturizers should be applied within 3 minutes of exiting the bath to seal in the moisture that was gained.Bath in lukewarm (NOT hot water) to prevent drying out the skinPlace humidifiers in the home to restore moisture to the air. Remember to regularly clean humidifiers to prevent bacteria and mold growth. Aim to keep the humidity at 45-55%, anything above will aid in the growth of dust mites. If you are unable to afford a humidifier, a cheaper alternative is to place a bowl of water in each room which will increase humidity in the air.Avoid contact with fabrics that irritate the skin. Wool is a common fabric that causes people to scratch which increases itching. Check labels of clothing, hats, scarves, and gloves to ensure they are not made of wool.Avoid allergy triggers. Allergy testing in our office can help you identify your eczema trigger.

For more information about eczema management and to identify you allergy triggers please contact Allergy and Asthma Care of Brooklyn (347) 564-3211 to schedule your appointment.

Am I Allergic To Penicillin?

Am I allergic to Penicillin? 

Dr. Cascya Charlot of Allergy & Asthma Care of  Brooklyn explains that the answer is "Probably Not".

Penicillin allergies are the most documented drug allergy in the United States, reported to affect over 10 percent of the population.  However, recent reports have found that 9 out of 10 patients (90%) who report as penicillin allergic are incorrectly diagnosed.

Symptoms of rash and stomach problems are commonly mistaken as allergic reactions to antibiotics, though the majority are unrelated.

Why get tested?

Incorrect labeling of patients as "Penicillin allergic" is a leading cause for the overuse of broad-spectrum antibiotics which are more expensive and increased side effects.  This overuse of broad-spectrum antibiotics has directly resulted in the growing antibiotic resistance.

Overuse of broad-spectrum antibiotics for penicillin allergies has led to an increase in drug-resistant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA).  Broad-spectrum antibiotics also significantly increase the final cost of treatment for patients to use alternative medications.

Are tree nut allergies diagnosed too often?

Study finds 50 percent of those who think they’re allergic pass an oral food challenge.Many patients with a history of a single tree nut allergy are told to avoid all other tree nuts.  But is that necessary? If you have a tree nut allergy and were advised to avoid other tree nuts based only on a positive blood or skin prick test, you may not be allergic to the other nuts. New research strongly suggests you should consider having an oral food challenge to properly diagnose additional nut allergies, especially if you’ve never had a reaction to eating those tree nuts before.A new study in Annals of Allergy, Asthma and Immunology, the scientific publication of the American College of Allergy, Asthma and Immunology (ACAAI) showed that among people allergic to one nut who have a positive test to other tree nuts, more than half passed an oral food challenge to other tree nuts without a reaction. Passing an oral food challenge means you aren’t allergic to that nut. Tree nuts include almonds, cashews, walnuts and hazelnuts, but not peanuts. The study noted that nearly none of the people allergic to peanut, but sensitized to tree nut, were clinically allergic to tree nut. This is the first study indicating that peanut allergic people may not need to avoid all nuts.“Too often, people are told they’re allergic to tree nuts based on a blood or skin prick test,” says allergist Christopher Couch, MD, ACAAI member and lead author of the study. “They take the results at face value and stop eating all tree nuts when they might not actually be allergic. We examined records of 109 people with a known tree nut allergy to an individual nut. They were tested for other tree nuts they had never eaten before using blood or skin prick tests. Despite showing a sensitivity to the additional tree nuts, more than 50 percent of those tested had no reaction in an oral food challenge.”  An oral food challenge is considered the most accurate way to diagnose food allergy. During an oral food challenge, the patient eats tiny amounts of the food in increasing doses over a period of time, followed by a few hours of observation to see if they have a reaction. An oral food challenge should only be conducted under the care of a trained, board-certified allergist. You should never do one on your own since if you are allergic, you could have a severe, life-threatening reaction.“Previous studies suggested people with a tree nut allergy, as well as those with a peanut allergy, were at risk of being allergic to multiple tree nuts,” said allergist Matthew Greenhawt, MD, chair of the ACAAI Food Allergy Committee and study co-author. “We found even a large-sized skin test or elevated blood allergy test is not enough by itself to accurately diagnose a tree nut allergy if the person has never eaten that nut. Tree nut allergy should only be diagnosed if there is both a positive test and a history of developing symptoms after eating that tree nut.”Dr. Greenhawt stressed the study did not include challenges to nuts that the individual had a documented history of having a reaction to when eaten.  “The practice of avoiding all peanut and tree nuts because of a single-nut allergy may not be necessary,” says Dr. Greenhawt. “After an oral food challenge, people allergic to a single tree nut may be able to include other nuts in their diet."

Advances in Allergen Immunotherapy at NYM

Dr Charlot cropped

To call allergen immunotherapy time-tested is an understatement. Commonly known as "allergy shots," the introduction of allergen immunotherapy predates Prohibition, and has been an effective treatment for patients living with severe allergies since Herbert Hoover sat in the White House.

Almost a century later, there is an ever-expanding array of effective, once-a-day medication available to treat allergy symptoms. But immunotherapy remains the only treatment that can alter the natural course of an allergic Cascya Charlot, M.D., was recently appointed director of NYM's Division of Pediatric Allergy and Immunology. disease like chronic rhinitis (hay fever) or allergic asthma, and permanently reduce the frequency and severity of allergy symptoms such as severe congestion, sinus pressure, grogginess and sleeplessness. Furthermore, ongoing research and refinement of immunotherapy guidelines have made immunotherapy treatments for outdoor and indoor allergies more effective than ever before. Perhaps this is why, more and more, Brooklynites are requesting allergen immunotherapy for their children, says Cascya Charlot, M.D., who was recently appointed director of NYM's Division of Pediatric Allergy and Immunology.

"Children can start immunotherapy as early as age five, and many children living in Brooklyn are just reaching that age," says Dr. Charlot. "A full course of allergen immunotherapy takes time—usually three to five years, starting with weekly visits for injections for the first six months, and then monthly visits for the remainder. However the benefits of immunotherapy can last a lifetime, particularly for children living in New York City, where pollen, mold spores and dust mites can be found around every corner. In addition, the first FDA-approved oral, injection-free immunotherapy (specifically, for grass pollen allergies) became available in 2014. More are sure to come."

For those with milder allergy symptoms that occur seasonally, over-the-counter treatments and lifestyle adjustments may be all that is necessary. Dr. Charlot is quick to point out that a common problem is that many of these patients do not even know that their springtime cold or upper respiratory infections have, in fact, been caused by a seasonal allergy.

"A simple 'scratch test,' performed by an immunologist, would likely have been able to identify that allergy in less than 30 minutes, and get the patient on the road to effective relief of symptoms," says Dr. Charlot. "What matters most is getting started, and finding the right treatment for each individual patient. Many parents of my patients tell me that they wish they had known about allergen immunotherapy when they were growing up, or that they had found out that they were allergic to pollen when they were younger. I tell them that there is no time like the present!"
