A reader asks:

I take Neurontin for chemical sensitivity. Do I need to adjust my light therapy use?


Neurontin (gabapentin) is an interesting drug. It was approved by the FDA for prevention of seizures. Although gabapentin is widely used to treat bipolar disorder (manic depression), the most carefully collected data fail to provide good evidence that it actually works as an anti-manic medication or mood stabilizer. Fortunately, in your example, there is no known reason that the use of light therapy and Neurontin would affect one another, so adjustment of your light dose is probably not needed unless you are experiencing light-related side effects.
