What Colazide® is for

Colazide® capsules are used to treat active ulcerative colitis and for maintenance of remission in patients who are intolerant to sulfasalazine. Ulcerative colitis is when the lining of the lower bowel becomes inflamed (swollen and irritated). Colazide® reduces the swelling and irritation.

Your doctor will have explained why you are being treated with Colazide® and told you what dose to take.

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

Your doctor may prescribe this medicine for another use. Ask your doctor if you want more information.

Colazide® capsules are not addictive.

The usual dose is 2 capsules taken twice daily. Your doctor may adjust this dose up or down depending on how you respond.

If you forget to take it

If you forget to take a dose, take it as soon as you remember as long as it is 4 hours before it is due, and then go back to taking it as normal.

If it is less than 4 hours until your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
