The two Types
 There are a number of different types
of antibiotics that work in two ways.
 One type is bactericidal and the other
type is bacteriostatic.
What the Two types do
 Bactericidal is an antibiotic that kills
bacteria.
A type of bactericidal is penicillin.
These particular types of antibiotics
usually interfere with the formation of
the bacteria’s cell wall or the cell
contents.
 Bacteriostatic stops the bacteria from
multiplying.
Side Effects
 Common Side Effects Include:
Diarrhea, feeling and being sick (of
course), and fungal infections of the
mouth and digestive tract.
 Rare Side Effects Include:
Kidney stone formation, abnormal blood
clotting, sensitivity to the sun, and
deafness.
Additional information
 Some people have allergic reactions to
antibiotics; especially to penicillin.
 Allergic reactions include:
 Rashes, tongue swelling, and trouble breathing.
 Use antibiotics with caution and inform your
doctor if you are pregnant or have a reduced
liver or kidney functions.
 Antibiotics may clash with other medications.
 Antibiotics can be taken orally, by injection, or
applied directly to the affected area.
