Mezavant/Mesalazine
Mezavant is a prescription anti-inflammatory and is used for gastrointestinal disorders. Thanks to the sustained-release formulation, the active ingredient in this medication, mesalazine (from the aminosalicylate group), is released in a controlled manner. Excipients: acetylated monoglycerides, castor oil, colloidal silicon dioxide, ethylcellulose, hydroxypropyl methylcellulose, starch, stearic acid, sugar, talc, and Chinese wax. The active substance is mesalazine from the group of aminosalicylates. Mesalazine is believed to alleviate inflammation in the intestine by blocking the enzyme cyclooxygenase and inhibiting the production of prostaglandins in the intestinal wall.

Mezavant Tablets | Mesalazine Modified-Release for Ulcerative Colitis
When gut inflammation becomes persistent, it can affect everything from your energy levels to your daily routine. Mezavant tablets are designed to treat inflammation in the colon, offering targeted ulcerative colitis relief and supporting long-term digestive health.
Containing Mesalazine, this prescription IBS drug (used where inflammation is involved) works directly in the bowel lining to reduce irritation and restore balance in the gut.
What Are Mezavant Tablets Used For?
Mezavant tablets are used to treat ulcerative colitis and other inflammatory bowel conditions affecting the colon. They are commonly prescribed for:
- Active ulcerative colitis flare-ups.
- Preventing recurrence of inflammation.
- Long-term bowel inflammation treatment.
- Managing symptoms linked to gut inflammation.
This medicine focuses on reducing inflammation rather than muscle spasms, making it suitable for inflammatory conditions rather than standard IBS alone.
How Mezavant Tablets Work in the Gut
Mezavant tablets work by reducing inflammation throughout the colon and rectum. The active ingredient Mesalazine acts as an anti-inflammatory gut therapy, targeting the lining of the bowel where irritation occurs. It works by:
- Reducing swelling and redness in the colon.
- Supporting healing of the gut lining.
- Improving symptoms such as diarrhoea and abdominal discomfort.
- Maintaining stable colon care when taken regularly.
Its modified-release design ensures the medicine works across the entire colon for consistent effect.
How to Take Mezavant Tablets
Mezavant tablets should be taken once daily with food, exactly as prescribed during your consultation with Pharmacy Planet.
General guidance:
- Swallow the tablets whole with water.
- Do not crush or chew the tablets.
- Take at the same time each day.
Typical dosage: During flare-ups: A higher daily dose (usually 2.4g to 4.8g) may be prescribed. Maintenance phase: A lower daily dose (commonly 2.4g) is used to prevent symptoms from returning.
Important tips: Take the tablets with food to support proper absorption. Drink plenty of fluids, especially during episodes of diarrhoea, vomiting, or fever. Continue taking the medicine regularly, even if you feel better, unless advised otherwise.
Consistent use supports effective bowel inflammation treatment and reduces flare-up risk.

Mezavant tablets are suitable for adults with ulcerative colitis or inflammatory bowel conditions. They may be appropriate for:
