Constipation because of meds?

I have to take some meds for the rest of my life but after about a year now they have finally affected me in going to the bathroom. Actually down to only 2 times in a week. So I need to start taking a laxative with a softner every day to get things going again. Any suggestions? Alot of stuff I have tried does not work ie.. bran, fruit, so I guess I better go the laxative medicine route. Thanks.
