You have to dose your antibiotic, they should never be interrupted. There probably won't be an interaction, but an LSD session can cause a diminished immune response so that in the days after whatever you take the antibiotic for can gain on you.
Good question since it's a fungus, and the anti-biotics would "kill or slow down the growth of bacteria/fungus" -http://en.wikipedia.org/wiki/Antibacterial
I would not take anti-biotics with anything other than food and water.
Gotta love the internet.
Constantly updated outdated information. lol
Ah well,

I was on DMT, LSD, MXE, THC, antibiotics from the dentist and Ibuprofin 800mg from the dentist a week or two ago all at the same time with no issues. for being so high, it all went rather smooth I should say.
