Potential side effects of cold medications

Children who take over-the-counter cold medications may experience dried-out respiratory passages and thickened nasal secretions. Overuse of nasal decongestants can lead to a “rebound effect” in which the drug becomes less potent and nasal congestion begins to worsen. Other potential side effects associated with cold medications include: Agitation Anxiousness Dizziness Drowsiness Fast heartbeat (tachycardia) or slow heartbeat (bradycardia) Fatigue High blood pressure (hypertension) High blood sugar levels Hyperactivity Insomnia Irritability Loss of appetite (anorexia) Nervousness Nightmares Racing heart Restlessness Retention of urine Unusual excitement Upset stomach

Drug or other interactions with cold medications

Parents should consult their child’s pediatrician before giving the child any additional prescriptions, over-the-counter medications, nutritional supplements or herbal medications. Substances that may preclude the use of decongestants or antihistamines include:

• Anticholinergic drugs (used for abdominal or stomach spasms or cramps)
  
  
• Antidepressants
  
  
• Central nervous system (CNS) depressants, including alcohol
