Which method involves ingestion of medication before exposure to disease?

Taking a drug ahead of time to prevent infection is chemoprophylaxis. It works by maintaining protective levels of medication in the body so that if exposure occurs, the pathogen is suppressed or eliminated before it can establish an infection. This differs from vaccines, which prime the immune system to recognize and fight pathogens, or from avoidance and barriers, which reduce risk by staying away from or blocking contact with the source. An example is taking antimalarial pills before traveling to a malaria-endemic area.
