sdn1977 is correct -if this is indeed an advice question, it needs to go to the patient's personal physician.
I had a nurse come by once asking for something OTC besides simethicone for her husband's painful gas. Apparently he was on an all fruit fad diet and refused to give it up. She got so mad when I told her there was nothing else and the only way to get rid of the gas was to back off on the fruit. Too, bad, so sad. She's a nurse. She ought to be able to accept reality.
