I have been taking i bear tan for 2 years or so, and have been complaining about tiredness pains in my leg and back and recently my Doctor wrote my annual prescription for Avropo, but the pharmacist said it was the same as irbesartan, and that there is no difference, and that she would only give irbesartan to me. I have been worried that my travel insurance would not be happy with this change. And looking on the Webb site I see people complaining about tiredness and leg pain, and I wonder if irbesartan is the cause?
