What is the best medicine for a spastic colon?
Unfortunately, there is no “best” medicine. Generally, we focus on anti-cholinergics to slow the colon since spasm tends to be the symptom that bothers patients the most. Drugs like Bentyl. Some patients, however, have more constipation, and these drugs merely increase this symptom. Generally, patients need to slow down the colon with Bentyl or equivalent drugs when the colon is spasming and speed it up with fiber, etc. when it is slow. Attention to your own colon and its rhythm is the best advice.
