Parents should exercise caution when choosing eye drops for their children. Never allow a child to use any medication without first consulting a physician.

Artificial tears are very safe and can be used at any age. Over-the-counter and prescription eye drops usually come in children’s formulations. Though most physicians are reluctant to prescribe anti-inflammatories for children, cromolyn sodium preparations are considered safe for children as young as 4. Antihistamines and antihistamines/mast cell stabilizers may be used for children ages 3 and older.

Most physicians discourage children from using decongestant eye drops that contain the ingredient naphazoline. This ingredient is known to make children jittery and overactive.

Side effects of eye drop use that are more likely to occur in children include:

• Restlessness
• Insomnia
  
• Nervousness
  
• Euphoria
  
• Tremors
  
• Seizures

Elderly patients may be more susceptible to side effects than younger patients. Side effects that are more likely to occur in elderly patients include:

• Dizziness (vertigo)
  
• Sedation
  
• Decreased blood pressure (hypotension)
  
• Urine retention
