Tagging some other members who have mentioned loratadine (Claritin) to find out if any of them may have experienced weight gain while taking it @gift440 @gigipatula @janemc @msele @debbieguk @scottbeammeup. @jenniferhunter @lilybell @1fancydancer also may have some thoughts on this.

Hmm, if that was the case, I think I would be twice the size I am. I took Claritin for years, switching to Xyzal a few years ago after it became ineffective.

I have taken oral allergy meds year-round since Allerest was released around 1960 and never experienced weight gain from any, though some caused other issues like dry mouth, dry eyes and drowsiness. I have probably taken every prescription and over-the-counter antihistamine that has even been released. I am so pleased with the nasal versions that reduce my need for double doses of the pills. We hit a "pollen-patch" in our travels last week - even our car was covered with bright yellow tree pollen - my poor husband was miserable in spite of using Azalastine nasal spray, Benadryl and Claritin. Hoping that being in Minnesota, with less stuff blooming, will give him some relief.

Hi, @radinski - were you and your doctor able to come to a conclusion about the allergy medications you were taking and weight gain?
