Digoxin has a similar ring structure to estrogen. I have been taking this dosage for more than 5 years. I believe that I also have mild gynecomastia and have recently discovered that this is a Lanoxin side effect. I am a teenager and usally this condition would just be attributed to fluctating hormone levels, but it has been present for 5 years. What I am wondering is whether or not this will disappear after treatment with Lanoxin is discontinued.
Digoxin is a known cause of gynecomastia .
Stopping the lanoxin may help. However, sometimes this is irreversible. I am also a weight lifter. I have noticed a major decrease in my strength level since coming off of the drug. I was curious if Lanoxicap would have had an anabolic effect on me while I was taking it.
