Objective

Background TN is characterized by severe, intermittent unilateral facial pain. Patients may experience exacerbations that require visits to the ED. Traditional pain medications are usually ineffective. IV AEDs often provide immediate pain relief. Yet knowledge of their effectiveness is not well appreciated. We describe our experience with IV AEDs in the ED.

Design/Methods 21 TN patients from the outpatient practice were seen in the ED for pain exacerbation (retrospective). Demographics and details about their TN from the outpatient and ED charts were recorded. Data were analyzed descriptively.

Results 15 women and 6 men (Median age = 69 (33-88)). TN duration: 11 years (3-20). Median current pain medications: 1 (0-3). 12 had R; 6 had L sided pain (3 unknown). TN exacerbation duration before ED visit: 10 days (2-90). 19 received IV fosphenytoin (FOS) (mdn dose = 1 gm; range: 500 - 1500 mg); 2 received IV levetiracetam (LEV) (mdn dose = 1 gm; range 1gm - 1 gm). Pretreatment median pain score was: FOS- 10 (0-10); LEV: 8 (5-10). Post treatment pain scores: FOS: 0 (0-10) and LEV: 0 (0-0). Adverse events for FOS : diplopia, dizziness, sleepiness, and itchiness (21%); none for LEV. Median time in the ED: 6 hours, 25 minutes. One patient required hospitalization.

Conclusions IV FOS is effective for acute pain in TN, and was well tolerated. Preliminary data suggest that IV LEV may be an alternate therapy, especially when FOS allergy is present. IV AEDs provide an option in the acute management of TN while definitive therapies are planned. Further investigation is required to better understand the role of these medications.
