I went to an ENT doc for my cough (dry) and he prescribed 100 mg Gabapentin three times/day to help with the cough. I’ve had little or no reduction and it drives me crazy (hard to talk very long with anyone and had to drop out of church choir and barbershop chorus). From the responses above it seems like it might be good to try increasing the dose to 600-900 mg/day to get a real effect. I’m definitely going to call the doc and see what he thinks. I guess Gabapentin affects a brain center that among other things can often be effective in interfering with a chronic cough. Thanks to everyone who responded–gives me hope.
