Freddyj, There are two basic approaches to treating uc. The first is the meslamine-based drugs (asacol, lailda, apriso, rowasa, meslamine suppository, etc) are anti-inflammatory medications. The second approach is everything else, which targets the immune system in some way: biologics (remicade, humira, simponi, entyvio/vedolizumab), immunosurpressive meds (6mp, imuran, aza), and steroids (prednisone, endocort, uceris, etc.).
Immunosuppressive drugs (6mp, imuran, aza) reduce your white blood cell count. White blood cells are the attack-dog of the immune system. Less white blood cells in your system, less uc inflammation can be caused. The side effects of these drugs are pretty statically rare. The scariest is lymphoma which as 4 in 10,000 (or 0.004%) odds of effecting you. More common is an increased odds of contracting an infection, and it becoming severe if not treated. These are things like UTI's, bronchitis, etc. Basically, see your dr sooner rather than later if you are suspect you might have one (you don't have to be a germaphobe or anything).
Biologics interfere with the immune systems natural process of signalling the need for an attack on body tissue, responding to attack signal, and the attack itself. The TNF-alpha medications are pretty similar: remicade, simponi, and humira. Of those remicade has been around the longest, and is often considered to be the most effective of the group (60% of uc patients see improvements after taking remicade). Second most effective is simponi. Humira is last. All of these tnf-alpha blocking meds carry a lymphoma and increased risk of infection warning on them. Odds of lymphoma 6 in 10,000 (or 0.006%) when used at the same time as an Immunosuppressive drug which is often the case/recommendation.
Entyvio/vedolizumab is the newest of the biologics, and presumably has the safest profile of them. Entyvio targets gut-specific tissue, and leaves the rest of your body alone. As such, it does not carry the lymphoma risk that the above meds do. It does not include the increased risk of infections as the above meds do. It's new to the market, not all insurances cover it yet, not all GI's prescribe it yet. It is certainly something that looks promising. You likely, need to have failed another biologic medication before you can get it. Price unknown at this point.
