I have developed a weird pus-cum-blackhead type of pimple on my nose. Please tell me what can I do to get rid of it overnight. It's really urgent.

No miracles . . . Go see your Family Doc or Dermatologist. On rare occasions, s/he can lance boil & perhaps inject corticosteroid to minimize inflammation (although this isn't w/o risk). Bottom line, there's no pill to magically make it disappear overnight. Sorry!
