It is a regimen of a week or so and can prevent the infection in many cases if started soon after exposure to the infecting agent. You should consult your doctor for the same and start it if he advises. Please be careful in the future, you have a long life ahead. Make it healthy. Feel free to contact me directly on Ask a Specialist section of the website. Chat Doctor.  </s>
