"Mylan now owns Denavir and they have jacked up the price to US$1000 a tube.  Not worth it.  The patent will expire in 2020.  I have stop using it even though my insurance covers this for an $30 co-pay.

I have tried taking L-lysine and vitamin C during an outbreak. They worked almost as well,

In the US,the over-counter Abreva works as well for me.  It cost at most $15 a tube.

If you are outside of the US, you can easily get generic Acyclovir 5%  for less than $10 a tube.


Try to reduce stress in your life, exercise and eat well.  You will probably get less occurences."
