Product Details

Description

Buy Teva-5 ASA Online from Licensed Canadian Pharmacies

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.

Uses and Benefits

What Are the Uses of Teva-5 ASA?

Teva-5 ASA is used to treat mild to moderate:

  1. Ulcerative colitis (primary use)
  2. Crohn’s colitis (off-label use)

What Are the Benefits of Teva-5 ASA?

  • Improve energy levels, appetite, and overall daily functioning by controlling gut inflammation.
  • This medicine may help delay or reduce the need for steroids, which often have more long-term side effects.
  • Regular use can decrease flare-up frequency.
  • In some settings, it is also used for mild to moderate Crohn’s disease involving the colon, particularly Crohn’s colitis.
Dosage
Teva-5 ASA Dosage for Active Ulcerative Colitis in Adults
  • Total daily dose: Take 2.4 g to 4.8 g per day, which equals 6 to 12 tablets of 400 mg. It is divided into multiple doses throughout the day.
  • Common regimen: It is 800 mg to 1600 mg, three times daily (for example, 2 to 4 tablets, 3 times per day). The correct dose will depend on severity and tolerability.
Teva-5 ASA Dosage for Remission in Adults
  • Maintenance dose: The total daily dose is often 1.6 g to 2.4 g per day, which equals 4 to 6 tablets of 400 mg. It is taken once per day or in divided doses.

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.

Usage Guide

How to Take Teva-5 ASA?

To take your Teva-5 ASA 400 mg tablets correctly, follow these instructions:

  • Follow the exact schedule your specialist gives you.
  • Swallow each tablet whole with a full glass of water.
  • You don’t need to crush or break these tablets, as the coating present on the tablets makes sure the medicine dissolves later in the gut, where inflammation is located.
  • You should take your doses at the same time every day.
  • You may take the tablets with food or without it. Some people prefer a small snack if they experience mild stomach discomfort.
  • Continue regular follow-up appointments so your care team can assess symptom control and adjust treatment if needed.
How It Works

How Teva-5 ASA Works

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.

Warnings

Teva-5 ASA Warnings

Black Box Warning: Teva-5 ASA (mesalamine) does not carry a black box warning, but official labeling highlights serious risks like kidney injury, hypersensitivity, and intolerance syndrome.

Below are other warnings that will help identify who should use Teva-5 ASA (mesalamine) cautiously or avoid it completely:

  • People who have allergies to salicylates (such as aspirin), aminosalicylates, or any ingredient in the tablet should not take this medication.
  • You will need regular kidney blood tests if you have existing kidney disease or are taking other medicines that affect your kidneys.
  • A small number of patients develop a reaction that looks very similar to a colitis flare known as Acute intolerance syndrome. Seek medical help if you suddenly develop:
  • Severe stomach cramps
  • Bloody diarrhea
  • Fever
  • Rash
  • People with moderate or severe liver problems may not process mesalamine well. In these cases, monitoring is required.
  • When you take Teva-5 ASA 400 mg tablet with azathioprine or 6-MP, the risk of bone marrow suppression (low blood cells) increases. Blood count should be monitored if these medicines are combined.
Safety Guide

Teva-5 ASA Precautions

Take these precautions while using Teva-5 ASA:

  • Never share this medicine with anyone else.
  • Do share your full medical history with your health care prescriber.
  • Blood and urine tests are usually done before starting mesalamine and repeated during long-term treatment.
  • Protect your skin from the sun. For that, use sunscreen, hats, or protective clothing when you go outdoors.
  • Do not stop taking Teva-5 ASA (mesalamine) on your own. If you do so, it can allow inflammation to return quickly. This also increases the risk of complications or hospitalization.
Missed Dose

Teva-5 ASA Missed Dose

Take your dose as soon as you recall on the same day, if you forget to take one dose. If the time is close to your next dose, skip the missed tablet and return to your regular dosing routine.

Do not take two doses at once or “double up,” since this can increase the chances of side effects like:

  • Stomach upset
  • Headache
  • Kidney strain

Speak with your health care professional about ways to simplify your routine or set reminders if you have a habit of missing or forgetting doses.

Overdose

Teva-5 ASA Overdose

Do not take too much of this medicine, as it may cause severe overdose symptoms, including:

  • Abdominal pain
  • Persistent vomiting
  • Diarrhea
  • Dizziness
  • Headache
  • Ringing in the ears
  • Shortness of breath
  • Confusion
  • Symptoms of kidney injury like:
  • Reduced urination
  • Swelling

In extreme cases, it may even contribute to serious kidney damage or other organ toxicity.

So if you notice an overdose, whether it is accidental or intentional, directly dial 911 or call the Poison Control Center at their toll-free number 1-800-222-1222.
