Yep. When it’s really bad and I need to be at the barn for more than just a quick ride, I take Zyrtec-D or Claritin-D. The D is critical. It’s a little, ah, intense for me to take every day, but it’s reliably effective when I need it.
I keep up with Flonase or similar every day during prime season. The other symptoms, I suffer through and whine until I can get home and shower. Moving closer to the coast drastically improved my springtime quality of life, but I still have some difficult days. There are prescription eye drops and inhalers and the works should you want to go that route with your doctor.
