After my heart attack 6 years ago, I was on digitek for a few months only. The known side effects of digitek: "Apathy, blurred vision, breast development in males, change in heartbeat, confusion, diarrhea, dizziness, headache, loss of appetite, lower stomach pain, nausea, psychosis, rash, vomiting, weakness, yellow vision" I was concerned with the prescription when there was a recall. As it turned out it was the generic "digitek" for digoxin.
