Abnormally low blood pressure may occur from peripheral actions. However, elevated blood pressure may also be seen secondary to the anxiety resulting from the effects on other organ systems. Likewise, bradyarrhythmias are common from the antimyasthenics, but rapid heart rate may occur secondary to the anxiety resulting from the effects on other organ systems. Respiratory rate may be increased in patients with airway compromise. seizures and coma have been described; profound weakness and muscle fasciculations may also occur. In less severe cases, headache, dizziness, and dysarthria may occur. Parkinsonian-like symptoms have been reported during therapeutic use of pyridostigmine.
Cramping, abdominal pain, hyperperistalsis, vomiting, and diarrhea have been described.
