Colazal has worked for me better than any of the older 5-ASA meds; it really gave me my life back!
Be sure to take it with food + drink plenty of water throughout the day-- so that it travels to your colon optimally. I started taking it during Phase 2 of NIH clinical trials, when the recommended daily dose was 9 capsules. This has since been lowered to 6 capsules daily, but there are members writing to this site who take the higher dose & seem to do well on it. Hopefully, you'll experience real improvement with fewer bms & more formed ones within a couple weeks, but it can take longer depending on the extent of your inflammation & symptoms. Good luck & take care. / Old Hat (nearly 30 yrs with left-sided UC; currently on 3 Colazal daily; seem to be back in remission)
