What are symptoms of an overdose on Aleve?

Symptoms of naproxen sodium overdose include:

  • Agitation
  • Blurred vision
  • Coma
  • Confusion
  • Convulsions (seizures)
  • Diarrhea
  • Dizziness
  • Drowsiness
  • Headache – severe
  • Heartburn
  • Incoherence (the person is not understandable)
  • Movement problems
  • Nausea
  • Rash
  • Ringing in the ears
  • Slow, labored breathing
  • Stomach pain (possible bleeding in the stomach and intestines)
  • Unsteadiness
  • Vomiting
  • Wheezing

Another symptom that wasn’t mentioned is death. I think that’s always a possibility worth noting. With the symptoms listed though, it’s never a good thing.
