How many times can i use plan b?

Not sure: As you know this drug is designed for "emergency use" not routine birth control. In addition, it does not protect you from sexually transmitted diseases. If you feel you are using it too often, consider other forms of birth control.

There is no: maximum number of times that Plan B can be used. But there is something wrong if it needs to be used repeatedly. It is only designed for emergency use after failure of the normal form of birth control.
