Other signs and symptoms may include miosis (pinpoint pupils), blurred/dim vision, headache, nausea, vomiting, diarrhea, copious secretions/sweating, muscle twitching/fasciculations, dyspnea, seizures, and unconsciousness. If a person survives twitching, there may be long-term neurological problems.
