[|Human|] My 9 year old daughter is saying she sometimes feels like she cannot take a deep breath. She is not wheezing, that I can tell, and this passes, usually after resting or sleeping. She is on daily zyrtec and has no history of asthma before. She does not complain of any other symptoms with this.
[|AI|]  Hello. Thank you for asking at Chat Doctor. If your daughter is not wheezing, not having fast breathing and not coughing, you should not worry about asthma at present. Feeling of not able to take deep breath can be due to nasal obstruction. Common causes can be allergic rhinitis, chronic sinusitis, or adenoids. I guess she is taking daily Zyrtec for allergic rhinitis. If she is feeling nasal obstruction I would suggest her to take montelukast along with Zyrtec for 2 weeks. If this does not improve, I would suggest consulting a pediatrician who will examine her in detail and may suggest her some investigations to identify the cause. Hope this will be helpful to you. Wish your daughter the best of the health. Regards.
