If you’ve fallen and you have a cut, you’ll want to have an antiseptic or disinfectant handy to clean and sterilize the area, before any cream or ointment is applied or prior to a bandage sealing the wound. Generally speaking, antiseptics and disinfectants are one and the same, in that the job of antiseptics is to disinfect. They are chemical agents that slow or stop the growth of microorganisms (germs) on external surfaces of the body and help prevent infections. They include hydrogen peroxide, chlorexhidine and alcohol wipes. Calamine lotion is incredibly versatile and can be used to treat anything from nasty sunburn to poison ivy to itchy bug bites.
