Has anyone tried taking guaifenesin for symptom relief? I don't suffer from IBS, but my wife does. She's had very little help from her doctors - primary to GI specialists. Since she was in pain most of the time, we (she & I) brainstormed as to what we can do to relieve symptoms. One the ideas we discussed was trying to increase the mucous layer protecting the GI tract by taking guaifenesin since it is used in cold medications for mucous production & relieve nasal & chest congestion.
Within a 4-5 days of taking 1200 mg of guaifenesin, her GI pain levels went from 6/7 to 2. She stayed on it a several more days and then stopped. Her pain level went back to 6. After about week restarted guaifenesin at 2x1200 a day (max dose). The pain subsided significantly.
We tried this A/B test a couple of more times with the same result. We shared it her primary physician. We're wondering if there are others with similar experiences using guaifenesin for IBS symptom relief.
