Chickenpox - Wikipedia, the free encyclopedia
"If oral acyclovir is started within 24 hours of rash onset it decreases symptoms by one day but has no effect on complication rates. Use of acyclovir therefore is not currently recommended for immunocompetent individuals (i.e. otherwise healthy persons without known immunodeficiency or on immunosuppressive medication). Children younger than 12 years old and older than one month are not meant to receive antiviral medication if they are not suffering from another medical condition which would put them at risk of developing complications.[36]
Treatment of chickenpox in children is aimed at symptoms while the immune system deals with the virus. With children younger than 12 years cutting nails and keeping them clean is an important part of treatment as they are more likely to scratch their blisters more deeply than adults.[37]
Aspirin is highly contraindicated in children younger than 16 years as it has been related with a potentially fatal condition known as Reye's syndrome.[38]
Some parents believe that it is better for children to contract chickenpox than to get the vaccine. They even go to the extent of exposing their children to others who have the disease – even by taking them to "chickenpox parties." Doctors counter that children are safer getting the vaccine, which is a weakened form of the virus, than by getting the disease, which can be fatal."
