My husband is on the taf/mek combo and on his second month with a reduction in dosage last week. My question is regarding side effects. My husband has a sensitive stomach to begin with, but has been having all day diarrhea and sharp pains in his large intestine area. It's so hard to see him suffer for days on end. Has anyone had stomach issues with this combo and found some relief? The dosage has been reduced to try and help but the pain and mass exodus of his stomach started again this morning.
