This drug can increase the risk of suicidal thoughts and behavior. This risk is higher in children, teenagers, and young adults. Tell your doctor if you have a history of suicidal thoughts or behaviors.

People with glaucoma

This drug may dilate your pupils (make them wider), which may trigger a glaucoma attack. Tell your doctor if you have glaucoma before taking this drug.

  1. Research in animals has shown adverse effects to the fetus when the mother takes the drug.
  2. There haven’t been enough studies done in humans to be certain how the drug might affect the fetus. 

Talk to your doctor if you’re pregnant or planning to become pregnant. This drug should be used only if the potential benefit justifies the potential risk to the fetus. 

Women who are breast-feeding

Escitalopram may pass into breast milk and may cause side effects in a child who is breast-fed. 

Talk to your doctor if you breast-feed your child. You may need to decide whether to stop breast-feeding or stop taking this medication.
