In what activities can children who are taking anti-clotting medications participate, and what precautions should be taken?

Parents should talk to their child’s doctor about specific activity limits and precautions while their child is on an anti-clotting medication regimen. In general, children who are taking anti-clotting medications should:

• Always wear seat belts in motor vehicles
• Always wear helmets on bikes, skateboards, scooters, etc.
• Avoid activities that are high-risk for injury, especially head injury
• Avoid high-impact sports like American football, ice hockey, etc.

Parents should discuss with the doctor whether their child with recent DVT/PE or who is taking anti-clotting medications needs other activity limits. Things to consider include the child’s:

• Age, development and degree of judgment
• History of injuries and falls
• Skill with a particular activity
• Degree of supervision (supervision of activities by a responsible adult may decrease the risks of injury and bleeding)

Because staying active, rather than sedentary, helps to reduce the risk of new DVT/PE, doctors often advise parents to permit and encourage participation in regular but safe exercise. While every child is unique, activities that are age-appropriate, supervised, and low-risk for injury may be encouraged, such as walking on a well-paved path or a treadmill, and biking on a well-paved path while wearing a helmet, or riding a stationary bike.
