Clonidine
"Used Clonidine Transdermal for 3 months, brought BP of 169/114 down to average of 135/90. Had swelling of face, redness/swelling/itching of eyes and blurred vision. Made it extremely hard to function with tiredness and inability to think, and worsened feelings of depression. After 3rd month, developed painful itchy rashes at patch site even with application of Benedryl spray before application. Became allergic to jewelry, deodorants and some foods. Trial of Lisinopril was a nightmare, so had to go back on the patch with worsened symptoms. Have been off for two days and pressure is spiking. I am to try another med, but am experiencing prolonged allergic reaction at patch sites and am nervous about the consequences."
