Can I use gabapentin if I have COPD?

Hi, spindler!
"People with chronic obstructive pulmonary disease (COPD) who take gabapentin (Neurontin, Gralise, Horizant) may experience serious breathing problems, including respiratory depression, which can be fatal. Other populations at risk include the elderly and people who take medications that depress the central nervous system, such as opioids, benzodiazepines, or antihistamines."
There is a potential risk so you'd take gabapentin only under your doctor's supervision. However, they may determine that the benefit would outweigh the risk.
Give your doctor a call.
