INDICATIONS AND USAGE
Dalfampridine is a potassium channel blocker indicated to improve
walking in adult patients with multiple
sclerosis (MS). This was demonstrated by an increase in walking speed
(1, 14).
DOSAGE AND ADMINISTRATION
The maximum recommended dosage is 10 mg twice daily (approximately 12
hours apart). There is no
evidence of additional benefit with doses greater than 10 mg twice
daily. Adverse reactions, including
seizures, were more frequent at higher doses. (2.1)
Take with or without food. Administer tablets whole; do not divide,
