"Feeling grateful today 💐
My amazing team surprised me for Boss's Day.
Two years in, and I couldn't be more proud of what we're building together at TexasAllergyMD.
These are the moments that remind you why you do what you do.

As an allergist, I never recommend Benadryl.👀....
Benadryl (active ingredient: diphenhydramine) is a first-generation antihistamine that crosses the Blood Brain Barrier, causing significant sedation and cognitive effects.
Most are already exhausted due to their allergic symptoms of nasal congestion and stuffiness, itching and sneezing.
Why compound this effect with a first generation antihistamine?
All of our food allergy kiddos and adults receive a food allergy action plan which is a step by step emergency guide for handling food allergic reactions.
After epinephrine administration for a food allergic reaction, one needs to remain alert for proper ongoing medical assessment – not groggy and sedated from outdated medication, so I typically always recommend a non-sedating antihistamine such as (cetirizine, loratidine, fexofenadine) instead of a sedating antihistamine.
The global medical community is already taking action....
Countries like Germany and Sweden have begun restricting access to first-generation antihistamines entirely.
Meanwhile, in the US we have numerous second-generation options (cetirizine, loratadine, fexofenadine) that provide effective symptom relief with minimal side effects.
Consider this and discuss it with your trusted doctor and allergist.

Hi there.... from the American Academy of Allergy, Asthma & Immunology conference in San Diego!
While I miss seeing all my wonderful patients and staff, I'm busy learning about the latest treatments and research in food allergy care and general allergy care.
I'm excited to return to the office soon and put these new insights to work!
