circus. the crowd cheering until a stunt goes wrong. how exactly this happened. our "instant index" is next. he said humira is for adults like me who have tried other medications but still experience the symptoms of moderate to severe crohn's disease. and that in clinical studies the majority of patients on humira saw significant symptom relief. and many achieved remission. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where certain fungal infections are common and if you've had tb hepatitis b, are prone to infections or have flu-like symptoms or sores. don't start humira if you have an infection. ask your gastroenterologist about humira. with humira, remission is possible. i accept that i'm not 21. i accept i'm not the sprinter i was back in college. i even accept that i live with a higher risk of stroke due to afib, a type of irregular heartbeat, not caused by a heart valve problem. but i won't accept giving it less than my best. so if i can go for something better than warfarin ...i will. eliquis. eliquis... reduced the risk of stroke better than warfarin plus it had less major bleeding than warfarin... eliquis had both. that really mattered to me. don't stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. while taking eliquis you may bruise more easily and it may take longer than usual for any bleeding to stop. seek immediate medical care for sudden signs of bleeding like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. i accept that i'm not as fast, but i'm still going for my personal best... and for eliquis. reduced risk of stroke... plus less major bleeding. ask your doctor... if eliquis is right for you. i love making sunday dinners. but when my back hurt, cooking all day... forget about it. tylenol was ok, but it was 6 pills a day. but aleve
