Sucralfate Medication: What It Is, How to Use It, and Safety Tips

If you’ve been prescribed sucralfate, you probably want to know how it helps and how to take it without hassle. In plain language, sucralfate is a medicine that coats ulcers in your stomach or intestines, forming a protective barrier so they can heal faster.

Doctors often recommend it for people with peptic ulcers, gastritis, or after certain surgeries that irritate the lining of the gut. It isn’t an acid reducer like omeprazole; instead, it works like a shield that sticks to the ulcer site.

How Sucralfate Works

When sucralfate reaches the acidic environment of your stomach, it turns into a gel‑like paste. This paste binds to the ulcer’s surface and stays there for hours, keeping stomach acid and digestive enzymes away. Because the ulcer is protected, the body can repair the tissue more efficiently.

The coating effect also reduces pain because the exposed nerve endings are less irritated. That’s why many patients notice less burning and discomfort within a few days of starting the drug.

How to Take Sucralfate Safely

Here’s a step‑by‑step routine that works for most adults:

• Take sucralfate on an empty stomach, usually one hour before meals or two hours after eating.
• Swallow the tablets whole with a full glass of water. Do not crush or chew them; the gel needs to form inside your stomach.
• Typical adult dose is 1 g (four 250 mg tablets) four times a day. Your doctor may adjust the amount based on the ulcer’s size and your response.
• If you miss a dose, take it as soon as you remember unless it’s almost time for the next dose. Skip the missed one – don’t double up.

Because sucralfate can bind to other medicines, separate it by at least two hours from drugs like antibiotics, thyroid meds, or iron supplements. This prevents it from interfering with absorption.

Common side effects are mild: constipation, dry mouth, or a chalky taste. If you experience severe nausea, vomiting, or an allergic rash, call your doctor right away.

People with kidney problems should let their doctor know, as sucralfate contains aluminum and can build up in the body. Also, if you’re pregnant or breastfeeding, discuss the risks and benefits with your healthcare provider.

Overall, sucralfate is a useful tool for healing ulcers when used correctly. Stick to the dosing schedule, keep a gap from other meds, and watch for any unusual reactions.
