Are laxatives bad for you?

I have trouble moving my bowls, I go about every 3 or 4 days, and when I do go it's only little drops. I went on vacation & ate a lot of food, my family has been running to the bathroom & for me, only once. I don't usually take laxatives so I was thinking that may help, but I was just reading some terrible things about them. So, my question is, is it bad to take 3 laxatives at once just one time to give myself a clean out? I don't want to continue taking them, just this one time. Btw, the brand I has says children and adults can take 1-3 laxatives at once.
