What causes dizziness despite taking Amlodipine Besylate for high BP?
Patient: I have been taking amlodipine besylate 2.5 grams for a year for high blood pressure.I am a healthy weight women with no other problems.In June of this year I had an epoxied of feeling faint and unsteady on my feet.It lasted for 4 days.I thought I was dehydrated.Now I am in Arizona for the winter and had this same thing happen 2 more times.Could my dosage be wrong or the blood pressure? I went to the doctor and have no infections so I am wondering if this could be the problem.I Have had problems with being dehydrated in the past so I drink tons of water.Being in Arizona I sweat more so that doesn t help my dehydrating problem.I am confused and my husband thinks is my thyroid.I had blood test before leaving home and all was well.
