More information would be exceptionally helpful to be able to answer your
question...such as reason(diagnosis/what the treatment is for), how long
you've been prescribed, if your Dr. has gradually increased your dose and is prescribing it this way, as directed. Again, more info. would be greatly helpful to better answer. If you're not prescribed to take it that way, yes it can most certainly be dangerous. Very dangerous to take more than what is prescribed for you.
