Why must treatment for an STD be prescribed by a healthcare professional?

Most likely to be able to have control. What we see with antibiotics when it's free is that people take it when they don t have to and do not ask a doctor first which they are supposed to. And we now have a epidemic of people being immune to one antibiotic after another.

Some STD's there is also a law on that you have to report everyone you have had sex with and let them know you have it. Everything goes into the journals. Sadly when it comes to this part not all can be trusted.

Many STD's also have the same symptoms so as a patient you will not know which one you have and risk taking the wrong one.
