Herpes during Isotretinoin treatment

Ah, god. Its so painful. I got one herpes labialis yesterday on my upper lip and it is extremle painful I can tell you.
I also dont really know what to do. While you are on Isotretinoin(roaccutane) you dermatologist will advice you to moisturise your lips a lot. When you read about this herpes labialis everybody advice you to keep the area as dry as possible.
The standart date to this herpes to go away is 7-12 days. I got it yesterday and I am already trying the advices on the internet. I have Zinc here in both topical and pill way and I also took B vitamin. Those seemed to be the most frequent advices for lips on the internet to treat herpes labialis.
Some are advicing Zovirax as a treatment or Aloe Vera creams and some natural products. Zovirax is the official treatment that a doctor should give you if you come with a herpes like this.

When I googled what is the contraindication between Accutane/Isotretinoin I find out that it is this drug is even used for the herpes labialis treatment. It was a little bit shocking for me. On the other hand I also find out that herpeses lesion on lip is occuring in shorther intervals during Isotretinoin treatment. Therefore, I expect that this is not the last herpes I am getting, but I believe it will last soon.

If anybody has any idea other idea, please, let me know. I will be extremely greatful. Of course, I will also let you know how it ended and what I think helped me with it.
