Combigan - How long does it take for this to leave the system?

With this one busymom,,, It in most cases won't take as long as other eyedrops and the doctor should give you clear directions on this if it is needed at all depends if they are switching to another drop or.if they have done the surgery etc if it were me i would call the doctor and get it right from the horses mouth but this drop is a combination medication which has not caused near the withdrawal problems as some of the others one of the two ingred.may have to be tapered but not near as long as the old drop so when they start talking about that be very clear with the doctor..I do hope this helps any questions just call the doctors office with any questions... your should be just fine with this
