Things To Know

  • Spring allergies will be here soon. Symptoms include sneezing, stuffy or runny nose, itchy nose, eyes or roof of the mouth. Many people with untreated allergy symptoms are not aware of how much better they can feel once their symptoms are properly diagnosed and managed. Our board certified allergists would be happy to help you come up with the treatment regimen that works for you this spring.

    Dr. Dania Wierzbicki


  • There are some allergy medications that you can take to control your symptoms so that you can still go out and enjoy the weather in the spring. Remember to use your saline nasal spray after your outdoor bike rides or runs to wash all of the pollens out of your nose.

    Dr. Gary Gross

Things to know this Spring Season

With spring in the air, tree and later grass pollens will be flying everywhere. Aside from taking your allergy medications, reducing your exposure to these pollens is also very effective at reducing your symptoms. Keeping your house and car windows closed, and limiting your outdoor activities on high pollen count days will help to reduce your exposure. If you are participating in outdoor activities, try to change your clothes and/or shower immediately after the activity to wash the pollens away. Saline nasal sprays can also be helpful to wash away the pollens that you breathed in through your nose.
