I have been taking losartan for a long time and have lower back pain. I was given physical therapy exercises and they did not work. I am always taking tylenol. I wait as long as I can so that I am only taking tylenol twice a day. I just read that losartan can be a side affect.
Thanks for your question, No it is not side effect from losartan, You have to do x-ray lumbosacral spine to assess the cause well. You should receive muscle relaxant as tizanidine 4 mg once before sleep.
