I have finally been diagnosed with IBS after dealing with it for years. I was instructed to follow the FODMAP elimination diet for 6 weeks and slowly add foods back in, and prescribed nortriptyline (25 mg for 10 days, increase to 50 thereafter). I have Ocular Hypertension (borderline glaucoma) and would love to know that others with Ocular Hypertension have been able to take this medication without negative consequences.
