Gabapentin, a non-benzodiazapine GABA analog, was modestly effective in a 14-week controlled trial in SAD. Most patients were titrated to a maximal dose of 3600 mg/day.58 Pregabalin 600 mg/day was effective for social anxiety, fear, and avoidance behavior in a 10-week controlled trial.63 Pregabalin was well tolerated, and the most common side effects were somnolence and dizziness.

Gabapentin acts by increasing GABA activity, although its exact mechanism of action is unclear. It causes dose-related sedation and dizziness. It has been shown in randomised controlled trials to be effective in social anxiety disorder (Pande et al. 1999) and to benefit some patients with panic disorder (Pande et al. 2000). Pregabalin is a related compovmd that has recently demonstrated efficacy in GAD in a phase III study (Pande et al. 2003).

Gabapentin is generally well tolerated in adult patients, and adverse effects of the drug are usually mild to moderate in severity (AHFS, 2000). The most frequent adverse effects of gabapentin as adjunctive therapy are somnolence, dizziness, and asthenia (Bruni, 1998).

BZs should be reserved for patients at low risk of substance abuse, those who require rapid relief, or those who have not responded to other therapies. Clonazepam is the most extensively studied BZ for treatment of generalized SAD. It improved fear and phobic avoidance, interpersonal sensitivity, fears of negative evaluation, and disability measures. Adverse effects include sexual dysfunction, unsteadiness, dizziness, and poor concentration. Clonazepam should be tapered at a rate not to exceed 0.25 mg every 2 weeks. Gabapentin was effective for SAD, and onset of effect was 2 to 4 weeks. j8-Blockers blunt the peripheral autonomic symptoms of arousal (e.g., rapid heart rate, sweating, blushing, and tremor) and are often used to decrease anxiety in performance-related situations. For specific SAD, 10 to 80 mg of propranolol or 25 to 100 mg of atenolol can be taken 1 hour before the performance. A test dose should be taken at home on a day before the performance to be sure adverse effects wUl not be problematic. Incomplete response to a first-line agent may benefit from augmentation with buspirone or clonazepam. 

Gabapentin is effective only for partial seizures and secondary generalised epilepsy (not absence or myoclonic epilepsy), in combination with established agents. It is also used for neuropathic pain. Gabapentin may cause somnolence, imsteadiness, dizziness and fatigue. 

The use of gabapentin has been reviewed (2). Its adverse effects are limited to neuropsychological disorders, namely dizzy spells, drowsiness, fatigue, and headache. The risk of interactions is also limited. 

The efficacy of gabapentin in dosages up to 3600 mg/day as adjunctive therapy has been studied in 2016 patients with partial seizures (3). The four most commonly reported adverse events were somnolence (15%), dizziness (10%), weakness (5.8%), and headache (4.5%). 

In an uncontrolled trial using dosages up to 6000 mg/day in 50 patients with refractory partial epilepsy, tiredness, dizziness, headache, and diplopia were the most common adverse effects (4). At dosages above 3600 mg/day three patients developed flatulence and diarrhea and two had myoclonic jerks. At least in some patients, gabapentin gastrointestinal absorption did not become saturated within the explored dosage range. 

Drowsiness, dizziness, fatigue, or ataxia are seen in 10-20% of patients who use gabapentin (SEDA-19, 70) (SEDA-20, 62) (10). Of 240 adults followed for about 1 year, only 4% discontinued treatment because of adverse events (SEDA-19, 70). Adverse effects... 

The efficacy and safety of gabapentin in relieving the symptoms of panic disorder have been studied in 103 patients in a randomized, placebo-controlled, doubleblind study for 8 weeks (14). Adverse events included somnolence, headache, and dizziness. One patient had a serious adverse event, a car accident, while taking gabapentin. 

The role of gabapentin in patients with neuropathic pain has been evaluated in a systematic review (16). The most common adverse events were dizziness and somnolence, which occurred in about 25% of patients ataxia occurred in about 8%. Adverse effects were dose-related. 

Two different regimens of add-on gabapentin have been compared in a double-blind, randomized trial (42). In 574 patients randomized to either slow initiation (300 mg on day 1, 600 mg on day 2, then 900 mg/day) or rapid initiation (900 mg/day immediately after the placebo lead-in), the four most common adverse events, which occurred equally in the two groups, were somnolence, dizziness, ataxia, and fatigue. The frequency of adverse events in a subgroup of elderly patients was similar to that in younger adults.

Gabapentin, a nonbenzodiazepine GABA analog, was effective for SAD in a 14-week placebo-controlled trial. The onset of effect occurred within 2 to 4 weeks. Patients reported dizziness and dry mouth. The effective dose of gabapentin ranged from 900 to 3600 mg daily given in three divided doses. ... 

Gabapentin has been of particular interest because it possesses a wide therapeutic index and a relatively benign side-effect profile. Side-effects reported with gabapentin are transient and minor, the most common being sortmolence, dizziness, ataxia and fatigue. It is not associated with hepatic or haematological problems. 

Overall, gabapentin is well tolerated with the most common adverse effects of somnolence, dizziness, ataxia, and fatigue. These effects usually are mild to moderate in severity but resolve within 2 weeks of onset during continued treatment. 

Adverse effects of gabapentin are uncommon and not serious. The CNS effects include mild to moderate sedation, fatigue, ataxia, headache, dizziness, and diplopia. Gabapentin may exacerbate myoclonus, but the effect is mild and does not require discontinuance of the drug (53,74). It has been associated with the development of neuropsychiatric adverse events in children. 

Pregabalin is another second-generation anticonvulsant that has recently obtained FDA approval for treatment of neurogenic pain, and several randomized placebo controlled studies have shown that this compound is efficacious in the treatment of painful diabetic neuropathy [32]. Doses between 300 and 600 mg/day have shown effect already apparent after 1 week of treatment. There are few clinically important drug interactions as there is no interference with the cytochrome 450 system. This compound requires minimal dose titration and seems easy to use. Side effects to gabapentin and pregabalin include drowsiness, dizziness and peripheral edema.
