Asacol (mesalamine) is a prescription medication specifically designed to treat mild to moderate ulcerative colitis, a form of inflammatory bowel disease. It works directly at the site of inflammation in the colon to reduce symptoms such as diarrhea, rectal bleeding, and abdominal pain. By delivering mesalamine to the affected area, Asacol helps induce and maintain remission, allowing patients to achieve better control over their condition and improve their quality of life. This medication is available in delayed-release tablet form, ensuring the active ingredient is released where it is most needed.
Features
- Active ingredient: Mesalamine (5-aminosalicylic acid or 5-ASA)
- Formulation: Delayed-release tablets designed for targeted colonic delivery
- Available strengths: 400 mg and 800 mg tablets
- Coating: pH-dependent release to prevent premature dissolution in the upper GI tract
- Prescription-only status, ensuring supervised medical use
Benefits
- Reduces inflammation directly in the colon, providing localized treatment with minimal systemic absorption.
- Helps achieve and sustain remission in patients with ulcerative colitis, decreasing the frequency of flare-ups.
- Alleviates key symptoms such as abdominal cramping, urgency, and bloody diarrhea, improving daily comfort.
- Supports mucosal healing, which is critical for long-term disease management and complication prevention.
- Generally well-tolerated with a favorable safety profile when used as directed under medical supervision.
- Enables many patients to reduce reliance on corticosteroids, minimizing associated side effects.
Common use
Asacol is primarily indicated for the treatment of mildly to moderately active ulcerative colitis in adults. It is used both to induce remission during acute episodes and to maintain remission once achieved. It may be prescribed as monotherapy or as part of a combination treatment plan, depending on disease severity and individual patient response.
Dosage and direction
The dosage of Asacol must be individualized based on the patient’s condition, response to therapy, and clinical guidance. For active ulcerative colitis, the typical adult dosage is 2.4 to 4.8 grams per day, administered in divided doses. For maintenance of remission, the usual dose is 1.6 to 2.4 grams per day, also in divided doses. Tablets should be swallowed whole with water; they must not be crushed, chewed, or broken, as this can compromise the delayed-release mechanism. Dosage adjustments may be necessary for patients with renal impairment.
Precautions
Patients should inform their healthcare provider of any history of kidney disease, as mesalamine has been associated with renal toxicity. Liver function should also be monitored during treatment. Use with caution in patients with pyloric stenosis or those taking other medications that affect gastric pH. Patients should report any signs of allergic reaction, such as rash, fever, or difficulty breathing. Regular follow-up and laboratory tests may be recommended to monitor safety and efficacy.
Contraindications
Asacol is contraindicated in patients with known hypersensitivity to mesalamine, salicylates, or any component of the formulation. It should not be used in patients with severe renal impairment (glomerular filtration rate less than 30 mL/min/1.73m²). Use is also contraindicated in patients with active peptic ulcer disease.
Possible side effect
Common side effects may include headache, nausea, abdominal pain, diarrhea, and flatulence. Less frequently, rash, dizziness, or mild hair loss may occur. Serious but rare side effects include acute interstitial nephritis, pancreatitis, pericarditis, blood dyscrasias, and severe hypersensitivity reactions. Patients should seek immediate medical attention for symptoms such as unexplained fever, sore throat, easy bruising, chest pain, or worsening abdominal pain.
Drug interaction
Asacol may interact with certain medications, including azathioprine and 6-mercaptopurine, potentially increasing the risk of blood disorders. Nonsteroidal anti-inflammatory drugs (NSAIDs) may enhance the risk of renal toxicity. Antacids and acid-reducing agents may alter the release profile of the delayed-released formulation. Always inform your healthcare provider of all medications, including over-the-counter drugs and supplements.
Missed dose
If a dose is missed, it should be taken as soon as remembered, unless it is almost time for the next dose. In that case, skip the missed dose and resume the regular schedule. Do not double the dose to make up for a missed one.
Overdose
Symptoms of overdose may include severe nausea, vomiting, diarrhea, sweating, tinnitus, and confusion. In severe cases, metabolic acidosis or renal failure may occur. There is no specific antidote; treatment is supportive and symptomatic. Immediate medical attention is required in case of suspected overdose.
Storage
Store Asacol tablets at room temperature (15–30°C or 59–86°F) in a dry place, protected from light and moisture. Keep out of reach of children and pets. Do not use beyond the expiration date printed on the packaging.

Reviews
Clinical studies and patient reports indicate that Asacol is effective for many individuals in managing ulcerative colitis symptoms and maintaining remission. Users often note improvements in bowel frequency, reduced bleeding, and overall quality of life. However, responses can vary, and some patients may experience side effects or require adjunct therapies. Adherence to prescribed dosing and regular medical follow-up are emphasized for optimal outcomes.
