CLADRIBINE (KLA dri been) treats multiple sclerosis (MS). It is often prescribed when other treatment options have not worked well enough or cannot be tolerated. It works by slowing down an overactive immune system, which prevents or delays worsening symptoms. It also decreases the number of flare-ups.
