Safe to take antibiotics and antivirals?

I have chickenpox and on day 4/7 of valcyclovir 3times a day(3gm total) and drinking a lot of water. Thankfully there has not been any side effects. I am urinating normally and always keeping my urine clear coloured. However recently i saw i got bacterial infection on my face, for which doctor said it might be staph so he gave cefpodoxime for 3 days 2x a day along with mupirocin ointment. My question is, as i am a little concerned about kidney and heard antivirals can put a lot of pressure on kidneys, i am scared if taking antibiotics will cause AKI or kidney issues. But at the same time i am afraid what if this infection increases, as its newr my eyebrows. Please guide me doctors. Thank you Attaching the infection image. Please guide me if i can take them alongside.
