Mercaptopurine
crohn's disease, maintenance
"This drug is a nightmare!!! Total fatigue with breathlessness, Arm weakness and numbness, nausea, light headedness. Now have developed tinnitus which is a constant pulsation through ears and head. My white blood cells have dropped dangerously low and my red blood cells are really poor. I am naturally now off the drug but don't know how long till I get back to health. ONLY GO ON THIS DRUG AS A LAST RESORT>"
