Irbesartan
"I started using Ibersatan about 2 years ago, after I developed severe side effects on Perindopril.  My blood pressure is well controlled and I thought the medicine was okay.  About 2 months ago, I went for holidays and missed out on treatment for a month%u2019s but I felt much stronger contrary to the expected.  On resuming treatment, I became very ill. I have been experiencing, hot flushes, cramps in my thighs, night mares, severe hot flushes and extreme weakness.  At first I thought it was malaria, but the tests were all negative. I took anti-malarial medication just to be on the safe side. The symptoms have just intensified. I also wondered (still are) for a while whether it is early menopause.  I have had several gout attacks while taking irbesartan."
