I have been taking gabapentin solution (liquid) for just over three years for postherptic neuralgia. I had terrible coughing, phlegm and even fluid in my ear from the prescription from one manufacturer but not from a different manufacturer.
I have severe all over body pain. I asked my doctor for Lyrica, but my insurance wouldn’t cover it so doctor substituted gabapentin. I have only taken it for 3 days 300mg a day. It has certainly helped the pain, but I have a terrible cough so bad that my sides are sore and I have a restless feeling. I will continue on it because anything is better than the pain.
