How it works

Gabapentin enhances the release GABA, a neurotransmitter involved in anxiety. Its effects are similar to the anticonvulsants pregabalin (lyrica) and tiagabine (gabitril).

How should I take it?

Gabapentin can be divided two to three times per day or taken all at once, with or without food. The levels start to drop in your blood stream 5-8 hours after taking it. Most people prefer to take it at night, as it can cause drowsiness, but it is fine to take in the morning if that works better for you. Some people take gabapentin on an as-needed basis, such as for anxiety or sleep. Most studies of anxiety used 2000-3000 mg/day. Lower doses may be used for sleep.

Maalox reduces gabapentin by 20%, so take gabapentin at least 2 hours after Maalox. Gabapentin decreases Vicodin (hydrocodone) levels by up to 20%. Other medications: Gabapentin has few significant interactions because it is not metabolized through the liver. The web sites below help you check for drug interactions.

How long do I need to take it?
