R and C topical
R & C topical ointment is a medication that is used to treat lice infestations. This medical formula has ingredients that are known as pyrethrins which are toxic to lice that are living on a person’s body, on their pubic hairs, or upon their scalp. Lice can spread quickly from one person to another and they need to be destroyed as soon as you discover them.
The medicine known as R and C is one of a number of formulas that are designed to kill the lice on contact. Although one treatment should kill any living lice that it comes in contact with but may not kill all of the nits (lice eggs) that are present. A second application is recommended by medical professionals. It be re-applied in 7-10 days so that any newly hatched nits are also killed.
According to medical experts this drug is more correctly categorized as a pediculicide. The two active ingredients that the formula contains are Piperonyl Butoxide and pyrethrins. The addition of the Piperonyl Butoxide intensifies the actions of the pyrethrins. This makes them the pyrethrins more effective at eliminating even long standing lice infestations.
The pyrethrins that the R & C ointment contains are absorbed by the lice. The formula is able to kill them because it systematically targets their internal nervous systems. Pyrethrins can be safely used on humans without producing similar effects.
R& C topical ointment is the brand name that is generally sold in Canada. The formula is a combination of Piperonlyl Butoxide and Pyrethrins. There are many other names for this external medicine that are available in the US.
