What medicine should I take for IBS?

[Truth0]

I have had IBS for over 20 years.  I currently take bentyl, dexilant and a probiotic.   It doesn’t help that much.  My stomach will hurt at least 4 or 5 days per week.   I go to the bathroom a lot and have bloating and gas.  Then some weeks I don’t go at all.  Any help on what medicines I should be taking so I can recommend to my doctor?

Hi.  The thing about IBS is that there are different types.  So, more details would help. This is a general list of available treating medicines for IBS.   https://www.mayoclinic.org/diseases-conditions/irritable-bowel-syndrome/diagnosis-treatment/drc-20360064  
Here are some non medication things you can try:
    Avoid foods that trigger your symptoms
    Eat high-fiber foods
    Drink plenty of fluids
    Exercise regularly
    Get enough sleep

They usually recommend redoing your diet as well.  

As to medication, there are general things that they offer that aren't specifically for IBS but used.  Most often for symptom management.  Then there are at least 5 fully approved for IBS meds also.
