Dalfampridine extended-release tablets are indicated as a treatment to improve walking in adult patients with multiple sclerosis (MS). This was demonstrated by an increase in walking speed [see Clinical Studies (14) ]. 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 ).

The use of dalfampridine extended-release tablets are contraindicated in the following conditions: History of seizure [see Warnings and Precautions (5.1)] Moderate or severe renal impairment (CrCl≤50 mL/min) [see Warnings and Precautions (5.2)] History of hypersensitivity to dalfampridine extended-release tablets or 4-aminopyridine; reactions have included anaphylaxis [see Warnings and Precautions (5.4)] History of seizure (4) Moderate or severe renal impairment (CrCl≤50 mL/min) (4) History of hypersensitivity to dalfampridine extended-release tablets or 4-aminopyridine (4)

Dalfampridine extended-release tablets can cause seizures; the risk of seizures increases with increasing dalfampridine extended-release tablets doses; discontinue dalfampridine extended-release tablets and do not restart if a seizure occurs (5.1) Avoid concomitant use with other forms of 4-aminopyridine (4-AP, fampridine), since the active ingredient is the same ( 5.3 ) Dalfampridine extended-release tablets can cause anaphylaxis. Discontinue and do not restart dalfampridine extended-release tablets if this occurs (5.4) 5.1 Seizures Dalfampridine extended-release tablets can cause seizures. Increased incidence of seizures has been observed at 20 mg twice daily (2 times the maximum recommended dosage) in controlled clinical studies of 9 to 14 weeks duration with dalfampridine in patients with MS. In open-label extension trials in MS patients, the incidence of seizures during treatment with dalfampridine 15 mg twice daily (1.7/100PY) was over 4 times higher than the incidence during treatment with 10 mg twice daily (0.4/100PY). In the post-marketing period seizures have been reported. The majority of seizures occurred at the recommended dose and in patients without a history of seizures, and generally within days to weeks of starting therapy. Dalfampridine extended-release tablets has not been evaluated in patients with a history of seizures or with evidence of epileptiform activity on an EEG, as these patients were excluded from clinical trials. The risk of seizures in …

8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with use of dalfampridine extended-release tablets in pregnant women. Administration of dalfampridine to animals during pregnancy and lactation resulted in decreased offspring viability and growth at clinically relevant doses [see Data]. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data Oral administration of dalfampridine to pregnant rats and rabbits …
