I have not taken Loratadine for about 6 months, and my low back/sciatica problems are still there. I did try acupuncture for about two months; did not have much effect on my back, but I have little or not sinus/allergy problems anymore (if that is what you were taking Loratadine for). Also, I did not have the migraine problems. Thanks for the response.
Rich,
I was taking Loratadine nightly. I recently also developed lower back spasms and sciatica, as well as bad migraines every day. I stopped taking the Loratadine. The migraines stopped. It will be a few days before I can tell about the back pain, because it ebbed and flowed. I had never heard of these side effects, because I didn't do research before I took it. I see that headache is a known side effect of Loratadine, but not back pain.
