Don't sleep with them on either. I mean you can..but it's best to just sleep with a pad on instead.
I think it depends on your flow. If you have a heavy flow, 4 hours would be best to change it. If it's light, then you can wear it a little longer. [ lightoftruth's advice column | Ask lightoftruth A Question ]
Dragonflymagic answered Friday July 19 2013, 3:24 am: A medical site said change it every four to six hours. Leaving one in too long, like all day or all night, can cause TSS Toxic Shock Syndrome.
With pads, you can see when you are no longer flowing, but with tampons you can't. I think 4-6 hrs might be a bit exaggerated but certainly if you put one on in the morning, I would change it by afternoon like by dinner. One put in at bedtime could be changed by morning. If you are closer to the end of a period where the tampon isn't soaked and starting to work its way out due to weight, its better to use panty shields to take care of the spotting. I have forgotton tampons before too, but only during the last day or two of cycle when i was barely spotting. Some use one on heavy days with a pad because the flow is that heavy.
