Lanoxin has similar structural characteristics to steroid hormones. This can produce estrogen effects in people taking the drug. Gynecomastia is only noted in men. Breast enlargement is less noted in women, but soreness often occurs. I have not noticed any side-effects, but I was recently told that lanoxin can contribute to memory loss.
Digoxin usually has nothing to do with memory loss unless the drug is given in high or toxic levels.
Then the memory problem is usually reversible. See what your level is and stay on the lower side unless you continue to have arrhythmias. My mother is taking a number of different medications and I am concerned about interactions and side-effects. Also, she has recently been sleeping more and seems depressed since starting a new drug, Lanoxin. She also takes Coumadin and Diabeta and Premarin.
