I use to go through a box of rennies a day, finaly decied to see a doctor. After Gastroscopy I got prescribed Lansoloc 30mg, later realised there is a 15mg asked doctor to prescribe that. I then switched to the generic version Lancap 15mg which is a lot cheaper and same ingredient, Lansapropyl. I take 1 a day and have not had any problems since.Get Lansolac 30MG. Contains Lansapropyl.
