Hello,
If you don't have major health issues along with the chicken pox infection, then don't take any medicines as of now. Once you are over with the 21 days period, take Malandrinum 200, two doses only. That will help you with the after effects.
If you have symptoms like running nose or bodyaches, then consult for the same.
Regards
