30
Q

Drug of choice for status epilepticus

A

Lorazepam, but its effects last for a shorter period of time, so longer lasting epileptics (phenytoin) are also given

31
Q

Clobazam use

A

Adjuvant to treat Lennox-gastaut syndrome (very rare form of epilepsy)

32
Q

Antiepileptics side effects nature

A

Intolerable, 25% of people who experience them will stop taking their meds

33
Q

Antiepileptics CNS side effects

A

Drowsiness, headache, somnolence, nystagmus, ataxia, slurred speech

34
Q

Antiepileptics GI system reactions

A

Nausea, vomiting, diarrhea, anorexia, constipation, gingival hyperplasia

35
Q

Felbamate side effects

A

Acute liver failure

36

Antiepileptic

37
Q

A

Skin rashes, pruritus, urticaria, urinary frequency, suicidal ideation

38
Q

Lamotrigine side effects

A

Serious skin reactions, such as SJS

39
Q

Ezogabine side effects

A

Urinary retention, and pain

40
Q

Antiepileptics pregnancy considerations

A

Association between antiepileptics and birth defects, when on birth control, carbamazepine, felbamate, oxcarbazepine, phenobarbital, phenytoin, primidone, and topiramate increase chance of pregnancy

42
Q

Felbamate side effects

A

Hematologic changes such as pancytopenia, leukopenia, aplastic anemia, and thrombocytopenia

43
Q

Trimethadione side effects as an antiepileptic

A

Hematologic changes, such as pancytopenia, leukopenia, aplastic anemia, and thrombocytopenia

44

46
Q
