Hi. I have gone through your question and understand your concerns. Lisinopril is ACE I group of medicine and hyperkalemia is known side effect of Ace. It depends on that when did you leave taking lisinopril, if It's yesterday than It's very early to say that its due to some other cause, but having hyperkalemia is very dangerous thing to have so I suggest you to consult your physician to get potassium levels under normal range. There are many causes of hyperkalemia so I suggest you to consult your physician so he/she should look for any treatable cause. Depending on the clinical findings and the results of the laboratory work, the following may be indicated:Glucose level - In patients with known or suspected diabetes mellitusDigoxin level - If the patient is on a digitalis medicationArterial or venous blood gas - If acidosis is suspectedUrinalysis - If signs of renal insufficiency without an already known cause are present (to look for evidence of glomerulonephritis)Serum cortisol and aldosterone levels - To check for mineralocorticoid deficiency when other causes are eliminatedSerum uric acid and phosphorus tests - For tumor lysis syn Chat Doctor. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate to ask. I will be happy to answer your questions. Wishing you good health.
