How high can the fever go with roseola?
The fever can be quite high. The fever averages 103.5 F (39.7 C), but it can go up as high as 106 F (41.2 C).
What is the treatment for the fever of roseola?
If the fever is not causing the child to be uncomfortable, the fever need not be treated. It is not necessary to awaken the child to treat a fever unless instructed to do so by a health-care practitioner.
If you wish to treat the fever, acetaminophen (Tylenol and others) can be used to lower a fever. Aspirin should never be used for fever in children or adolescents.
A child with a fever should be kept comfortable and not be overdressed. Overdressing can cause the temperature to go higher. Bathing with tepid water (85 F or 29.5 C) may help bring down a fever. If a child develops shivering during the bath, the temperature of the bath water should be raised. Never sponge a child (or an adult) with alcohol; the alcohol fumes may be inhaled, causing many problems.
Can the fever cause a seizure?
Yes. The high fever of roseola may trigger a seizure (a convulsion). Febrile seizures (convulsions due to fever) are common in children between 18 months to 3 years of age. They occur in 5% to 35% of children with roseola.
Is a seizure due to fever dangerous?
The seizure may look very frightening, but it is usually quite harmless (benign). Febrile seizures are not associated with long-term nervous-system side effects or brain damage. Anticonvulsant medications are very rarely prescribed for the treatment or prevention of febrile seizures.
