Canasa is an FDA-approved rectal medication that is used to treat mild to moderate ulcerative proctitis. Proctitis is a condition characterized by inflammation of the inner lining of the rectum. It works by blocking certain chemicals in the body that cause inflammation. Canasa is an anti-inflammatory drug that helps reduce irritation and swelling in the colon. Canasa is not a cure for ulcerative proctitis, but it may decrease rectal bleeding and the amount of mucus in the stool, as well as the number of stools.
The generic version of Canasa, mesalamine, is also available in different brand names, such as Lialda. Lialda is approved to treat ulcerative colitis. Canasa is administered as a 1000 mg suppository in the rectum at bedtime for 3 to 6 weeks.
Canasa is only available as a 1,000 mg rectal suppository. Consult your doctor before using Canasa to ensure that you're using the correct dosage. If a rectal suppository does not fit your lifestyle or medical needs, ask your doctor about Lialda, which is an oral tablet with the same active ingredient as Canasa. He or she can determine which treatment is best for you depending on your condition.
Common side effects of Canasa include rectal pain, stomach pain, dizziness, fever, and rash. Some side effects that occur may not require immediate medical care and should eventually go away after a while. Consult a healthcare provider if side effects persist or worsen.
Canasa may also cause serious side effects including kidney problems, liver problems, sun sensitivity of the skin, kidney stones, and allergic reactions. Seek immediate medical attention if you experience signs or symptoms of an allergic reaction, including rash, swelling of the face or throat, and trouble breathing. Other side effects can also occur since this is not a complete list.
Call your doctor, pharmacist, or the manufacturer for medical advice on Canasa, its related side effects and drug interactions. Talk to a healthcare provider about other possible side effects, warnings, and precautions before using Canasa.
