A) CNS depression
B) Hypotension
C) Recurrence of seizures
D) Nystagmus
Ans: C
Feedback:
Recurrence of seizure activity may result from abrupt discontinuation of the drug, even when the anticonvulsant is being administered in small daily doses. Abrupt discontinuation of the drug does not cause CNS depression, hypotension, or nystagmus. CNS depression, hypotension, and nystagmus are adverse reactions of phenytoin.
