Started Asacol 800 mg three times a day Side Effects

I started Asacol almost two weeks ago, and it worked very well after a couple of days, but after almost two weeks, I got very weak, dizzy spells, fatigue, like the flu. It's been five days, and most of the time I need to lay down. I couldn't go to work today. When does it stop? I stopped the medication four days ago. It was for colitis.

Hi,
Asacol interferes with absorption of the vitamin folic acid and this causes anemia.
Weakness, dizziness and  fatigue that you experience could be due to anemia.
Check your hemoglobin levels and take folate supplements.
