Hi.  I live in lone tree colorado.  We have a linden tree in the back yard, I have tested being allergic to this tree.  The last week I have horrible allergies.  What is the blooming period, how long does it last?  Are there any over the counter medicines I can take?  I already take zrytec.  Mostly I am unable to swallow.
Hello, Welcome to Chat Doctor, As you are known allergic to tree pollen, you should be very, very careful during the blooming period it may be dangerous to the life. I would suggest you to undergo absolute eosinophil count (AEC) which will be raised in the allergic condition. For the present symptoms you can take Tab Zyrtec, which you are having which helps to control the symptoms, but it is temporary. You need to avoid these pollen allergens to protect yourself from getting these allergy symptoms.Otherwise, you have to prefer immunotherapy either with subcutaneous immunotherapy (SUIT) or sublingual immunotherapy (SLIT). Thank you.
