Syncope in Children
Medically reviewed by Drugs.com. Last updated on May 4, 2025.
Syncope is also called fainting or passing out. Syncope is a sudden, temporary loss of consciousness, followed by a fall from a standing or sitting position. Syncope is usually not a serious problem, and children usually recover quickly after an episode. Syncope can sometimes be a sign of a medical condition that needs to be treated.
DISCHARGE INSTRUCTIONS:
Call your local emergency department (911 in the US) if:
- Your child loses consciousness and does not wake up.
- Your child has chest pain and trouble breathing.
- Your child has a seizure.
Return to the emergency department if:
- Your child faints, hits his or her head, and is bleeding.
- Your child faints when he or she exercises.
- Your child faints more than 1 time.
Call your child's doctor if:
- Your child has a headache, a fast heartbeat, or feels too dizzy to stand up.
- You have questions or concerns about your child's condition or care.
Medicines:
Your child may need any of the following:
- Blood pressure medicine can help your child's heart pump strongly and regularly.
- Steroid medicine can help your child's body balance fluids and salts. This will help prevent his or her blood pressure from dropping too low and causing syncope.
- Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell the provider if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.
Manage your child's syncope:
- Keep a record of your child's syncope episodes. Include your child's symptoms and his or her activity before and after the episode. The record can help your child's healthcare provider find the cause of his or her syncope and help manage episodes.
- Tell your child to sit or lie down when needed. This includes when your child feels dizzy, his or her throat is getting tight, and vision changes.
- Teach your child to take slow, deep breaths if he or she starts to breathe faster with anxiety or fear. This can help decrease dizziness and the feeling that he or she might faint.
Prevent your child's syncope episodes:
- Help your child know and avoid triggers. Certain events may bring on syncope. These events may cause your child to feel under pressure, upset, or fearful. When your child feels the symptoms, he or she can make movements to prevent a syncope episode. For example, have your child make a fist, cross his or her legs, or tighten arm muscles. Your child should not lock his or her legs while standing.
- Tell your child to move slowly from one position to another. This is very important when your child changes from a lying or sitting position to a standing position. Before your child stands up, have him or her sit on the side of the bed or couch for a few minutes. Then have your child take some deep breaths before he or she stands. Your child needs to stand slowly to prevent an episode. If your child is on bedrest, try to help him or her be upright for about 2 hours each day, or as directed.
- Follow recommendations from your child's healthcare provider. Your child may need to drink more liquids to prevent dehydration. Your child may need to have more sodium (salt) to keep his or her blood pressure from dropping too low. Your child's provider will tell you how much liquid and sodium your child should have each day. The provider will also tell you how much physical activity is safe for your child. Your child may not be able to play certain sports or do some activities, depending on the cause of the episodes.
- Watch for signs of low blood sugar. These include hunger, nervousness, sweating, and fast or fluttery heartbeats. Talk with your child's provider about ways to keep your child's blood sugar level steady.
- Be careful in hot weather. Heat can cause a syncope episode. Limit your child's outdoor activity on hot days. Physical activity in hot weather can lead to dehydration that triggers an episode.
Follow up with your child's doctor as directed:
Write down your questions so you remember to ask them during your child's visits.
