Teva-5 ASA, also called 5-aminosalicylic acid or 5-ASA, is a brand-name medication for mesalamine. It is an anti-inflammatory medicine that is used to treat inflammatory bowel disease (IBD), especially for people dealing with conditions like ulcerative colitis or Crohn’s disease.
Its delayed-release formulation works directly on the lining of the bowel to ease symptoms such as stomach pain, diarrhea, and bleeding. It is supplied as 400 mg enteric-coated oral tablets designed to pass through the stomach and release medicine in the intestine, where it is needed. A prescription is required to order Teva-5 ASA online from Canada.
It’s usually safe for adults and teens, but children should only use it under medical supervision. While most people tolerate it well, mild side effects like nausea or headaches can happen, and serious reactions should be reported right away. Take this medicine exactly as prescribed, store it properly, and rely on your health care provider’s guidance for safe and effective use.

Teva-5 ASA is used to treat mild to moderate:
Some patients do well on 800 mg two or three times daily after remission is achieved, but your provider tailors this based on your disease pattern.
To take your Teva-5 ASA 400 mg tablets correctly, follow these instructions:
Mesalamine in Teva-5 ASA reduces inflammation in the lining of the bowel, rather than affecting the whole immune system like steroids do. This medicine works locally inside the colon.
In ulcerative colitis and some types of Crohn’s colitis, the gut lining produces too many inflammatory chemicals called prostaglandins and leukotrienes (substances that trigger swelling and irritation). These are made through the COX (cyclo-oxygenase) and LOX (lipoxygenase) pathways.
Mesalamine is thought to modulate these pathways, which further reduces the production of these substances and calms inflammation in the bowel wall. Teva-5 ASA tablets are enteric-coated, meaning they stay intact through the stomach and dissolve only when they reach the terminal ileum and colon, where inflammation usually occurs.
Note: How this medication works is not fully understood. This working procedure is based on some literature suggestions.
Common Teva-5 ASA side effects may include:
Serious side effects: These are rare, yet if they occur, call your health care provider or your local emergency care services right away:
