Thanks for contacting HCM. Dear patient the tablet you were taking Adalat has side effect of causing swelling in ankles and legs so could have been responsible for that, thats why probably your doctor changed it to candesartan. Subsequently he added a diuretic and still you have not been benefited. I would suggest that you should be evaluated for cardiac and renal functions as long standing hypertension can cause complications like left heart failure and kidney damage which can also cause swelling in dependent parts of body(usually ankles and feet). in both such situations the usual drugs to control Blood pressure are not very effective and some special drugs are required. As you have waited for 2 weeks and not much benefited please go to your doctor and ask him to get you evaluated for cardiac and renal functions. regards
