But here's something important you need to understand. This medicine cannot completely cure a herpes infection. What it can do is control the spread of the virus within the body, reduce symptoms (pain, blisters), and help the infection heal faster.
Doctors may sometimes prescribe this medicine for other viral infections, so if you have any further questions about this, ask your doctor.
