Zrytex side effects -- joint pain

Hi Judy,

Thank you for your question! The known side effects of Zyrtec are dry mouth, headache, and fatigue. However, it's important to keep in mind that every medication can affect every person differently.  So even though it's not the likely cause of your joint pain, it is possible that Zyrtec is the culprit. If you really think it's the Zyrtec that may be causing the pain, I would recommend speaking with your doctor about it, and possibly stopping the medication for a few days to see if it goes away.

Best of luck,

Casey

well, I can tell you that within 24 hours of taking Zyrtec again for seasonal allergies; i started with quite annoying knee joint pain. after the third day, i couldn't take it anymore. i woke up the 4th morning (after NOT taking a pill on the 3rd nite) and low and behold, joint pain was gone! Coincidence? I think not. Now, my nose is running and I'm congested too boot; but I'll research yet another allergy relief method to try again. Also, I had this same reaction to Singulair.
