For High Blood Pressure "Chlorthalidone helped me with my blood pressure to go down but the side effects were just too much. I felt high and drunk on this medicine and I had only taken it for 3 days. The feeling would come in waves. I was prescribed 25mg once daily. My vision was very blurry and I became very confused and disoriented. It became difficult to walk. My legs cramped. I had heart flutters and irregular heartbeat for a few minutes. I had horrible anxiety and panic attacks on this med. I also had sharp pains in my toenails and my fingernails. My voice became hoarse and my eyes became bloodshot red with lots of pressure in my eyes. The room was spinning and I kept getting dizzy spells when I walked. I could not function on this. I could not concentrate or complete my daily tasks. I slept most of the day because of it. I stopped taking it and I feel better more and more every day. It was extremely scary to be on! I will never take this medicine again! It is definitely not for me!"

For High Blood Pressure "I have been on a lot of this type of medication. Benicar almost did me in, and I was traveling far from home. Different doctors have prescribed a lot of different meds. I cannot take this type of pill. I almost become crippled with chlorthalidone. It weakens my knees, legs, and ankles. I am a type II diabetic on insulin. My morning glucose tests run between 230 and 246."

For High Blood Pressure "I was started on chlorthalidone because losartan didn't lower my blood pressure, and I was having too many side effects with lisinopril. It lowered my blood pressure well for a few months and then seemed to stop working. During these three months, I was also dealing with heart palpitations. I completely stopped caffeine and alcohol. I had a Holter monitor test and was told I was experiencing harmless PVCs and PACs. My doctor doubled my chlorthalidone to try to get my BP back under control, and then I started to feel really terrible. Headaches, muscle cramping all over my body, weakness, fatigue, frequent heart palpitations. I thought it was just a little bit of dehydration since this medication is a diuretic, but my labs showed that my potassium dropped to severely low. I was taken off the medication and had my potassium replaced. Once my potassium was back to normal, I started to feel better, and after a few weeks, I also noticed that my heart palpitations had completely stopped."

For High Blood Pressure "It worked well at decreasing my systolic BP but gave me horrible migraines. I also had pins and needles in my feet, and some days I felt really weak and out of it, like I had an electrolyte problem."
