Hello,
Thank you for your query at DoctorSpring.com
Acne is known to occur with Valtrex, although less common than with other medications like Phenytoin. You need to consult your physician for a change of drug or consult a dermatologist for treatment of acne.
If you share the images of your acne, I can forward this consult to our dermatologist and get an opinion from her.
Regards,
InHouse Physician.

What about Famvir? Does it cause acne?

No, Famvir is not known to cause acne. It causes other side effects like weakness, loss of appetite, vomiting, diarrhea, weight gain, e.t.c
Feel free to discuss further,

Patient replied :
How does Valtrex cause acne?
Unfortunately, the Valtrex has more side effects compared to other anti-viral medicines.
Even though, the incidence is low, but still acne is one of the side effects.
