I have been taking Lisinopril for at least three years, since my pharmacy substituted it for Fosinopril. It never occurred to me that a particularly nasty side effect was coming from that medication until I ran out and didn't take it for a few days.
My lower legs had been swelling very badly for a few years, but I didn't associate the swelling with the drug, and I had been fighting it with compression hose and diuretics. Once I stopped the Lisinopril, 90% of the edema vanished.
