Treatments

Treatment

Talk with your child's doctor about the best plan for your child. You child may need:

Medications

Medicine can be used to treat PP depending on the type. They may stop or slow sexual growth. They also halt the rapid bone growth and encourage normal growth.

Psychological Support

PP may cause social problems in some children. Psychological support may be helpful. Talk to your child's doctor about what options are available.

Treatment of Underlying Conditions

If a health problem is the cause of PP, it will be treated.

Surgery

Surgery may be needed if PP is caused by a tumor or other lesions. The procedure will depend on the site and size of the tumor.

Ongoing Monitoring

The doctor will check your child’s height, weight, and sexual growth. This will help to note any changes or show if treatment is working.

Prevention

PP can't be prevented.
