  • Inform your doctor if your child has any heart complications, bleeding disorders, or epilepsy.
  • Sertraline is metabolized by the liver; thus, blood concentration may increase in the cases of liver disease. So, ensure the dose of the medication is adjusted by the doctor every week.
  • The FDA suggests screening for bipolar illness or manic disorder and taking the family history for suicides, mood disorders such as depression and bipolar disorderiThe psychological condition that makes the person experience severe mood swings and behavioral changes and psychiatric disorders before administering Zoloft. Zoloft may cause manic or depressive episodes or suicidal tendencies.
  • At the start of treatment, Zoloft may slow down reactions and cause sleepiness. So, be cautious when the child is riding a bicycle or doing tasks that require alertness.
  • This medication should not be administered with drugs that reduce blood clotting as it increases the risk of bleeding. These drugs may include aspirin, warfarin, heparin, and non-steroidal anti-inflammatory drugs (NSAIDs such as diclofenac, ibuprofen).
  • Consult a healthcare provider before the child uses any over-the-counter medication, herbal preparation, or health supplement.
  • All medications should be kept out of children’s reach.
  • In case a dose is missed, do not give a double dose the next day. The symptoms of overdose can be severe.
  • The dropper dispenser of Zoloft oral concentrate is made of dry rubber. Make sure your child is not allergic to it.

Zoloft is an effective drug for OCD in pediatric patients. When coupled with mental health therapies like cognitive behavioral therapy, it helps improve the quality of life. However, it may take a few weeks before the full effects show; thus, do not stop the medication abruptly if no improvement is seen. Always consult with your doctor before making any dose changes.
