What is Pentasa and How Does It Work?
Pentasa is an anti-inflammatory medication for inflammatory bowel diseases (IBD) like ulcerative colitis and Crohn's disease. The active ingredient is mesalazine (5-aminosalicylic acid).
It works directly on the gut lining to reduce inflammation, swelling, and pain. This helps induce remission during flares and maintains long-term comfort.
Available as Pentasa 500 mg (100 modified release tablets) and Pentasa 1 g (60 modified release tablets) . The modified-release design releases mesalazine gradually throughout the intestinal tract.
This gives consistent relief where needed most. Pentasa is now available through online consultation with our EU-licensed doctors at Prescriptsy.
Benefits of Choosing Pentasa
Managing chronic digestive conditions needs a reliable treatment. Buying Pentasa online through Prescriptsy means genuine medication with qualified medical oversight.
- Targeted Relief: Works locally in the intestines, unlike systemic steroids. This often means fewer body-wide side effects.
- Maintains Remission: Regular use can greatly reduce flare-up frequency for a more symptom-free life.
- Convenience and Privacy: Complete a medical questionnaire from home. An EU-licensed doctor reviews your case and issues a prescription if suitable.
- Discreet Delivery: Orders ship in plain, discrete packaging for full privacy.
How to Take Pentasa Properly
Follow your doctor's dosage instructions for the best results.
Administration
Swallow tablets whole with water. Do not crush or chew them. This would destroy the modified-release mechanism. Some forms may be broken into pieces or mixed with water or yogurt. Check with your doctor or the patient leaflet first.
Consistency
Take Pentasa consistently, even when you feel well. This prevents flares. If you miss a dose, take it when you remember. Skip it if your next dose is near. Never double up.
Possible Side Effects
Pentasa is usually well tolerated but is prescription-only. Our doctors assess your suitability before prescribing.
Potential Side Effects
Most are mild:
- Mild headache
- Nausea or stomach discomfort
- Diarrhoea
- Rash or itching
Seek help at once for allergic reactions (breathing difficulty or facial swelling) or unusual bruising and bleeding.
Important Considerations
- Kidney Function: Mesalazine can sometimes affect kidneys. Your doctor may need regular blood tests.
- Aspirin Allergy: Do not take Pentasa if you are allergic to aspirin or other salicylates.
- Pregnancy and Breastfeeding: Tell your doctor so they can give the most appropriate advice.
Medical information
Pentasa contains mesalazine (5-aminosalicylic acid), an anti-inflammatory agent that acts topically on the intestinal mucosa to treat ulcerative colitis and Crohn's disease.
Its unique ethylcellulose-coated microgranule formulation provides continuous drug release from the duodenum to the rectum, ensuring anti-inflammatory coverage throughout the entire gastrointestinal tract.
Pentasa is used to induce and maintain remission in mild to moderate inflammatory bowel disease, reducing mucosal inflammation, ulceration, and symptom frequency.
IBD management requires regular monitoring of disease activity, renal function, and full blood count.
A prescriber must confirm your IBD diagnosis, assess current disease extent and activity, and ensure that mesalazine is the appropriate treatment — or determine whether immunomodulatory or biological therapy is needed instead.
- Compare pharmacies – Browse Pentasa formulations (tablets, sachets, suppositories, enema) from verified UK pharmacies on Prescriptsy.
- Complete the health questionnaire – Provide your IBD diagnosis, disease location and current activity, kidney function, and current medications.
- Medical assessment – A registered doctor reviews your disease profile and confirms that mesalazine therapy is appropriate for your current needs.
- Home delivery – Your IBD medication is delivered reliably to support consistent treatment.
Prescriptsy offers a convenient online consultation for inflammatory bowel disease prescriptions with registered medical professionals.
