If potassium accumulates in your blood it can lead to a condition called hyperkalemia.
This can cause possibly life-threatening changes in heart rhythm.
It can be triggered by certain medications that make it harder for the kidneys to remove potassium, such as antibiotics, herbal supplements, beta-blockers and non-steroidal anti-inflammatory medications.
Symptoms include abnormal heart rhythm, slow heart rate and weakness.
