Sucralfate Uses


Sucralfate (Carafate) Uses

Sucralfate helps ulcers heal. It is used to prevent and treat duodenal ulcers (sores in the duodenum which is the first part of the small intestine). 

There may be other uses of sucralfate. Your doctor or health system pharmacists can give you further information on sucralfate drugs.

Sucralfate (Carafate) Mechanism of Action

Sucralfate covers the ulcer sites and protects the area from acid, enzymes, and bile salts, thus preventing further injury and allowing the ulcer to heal.

Sucralfate (Carafate) Doses

Sucralfate forms include a 1-gram tablet and a 1 gram/10 mL suspension. The usual dose is 1 gram four times a day to treat an active duodenal ulcer and 1 gram twice a day for maintenance therapy to prevent the recurrence of a healed ulcer.

Sucralfate Directions


How To Use Sucralfate (Carafate)

Sucralfate comes in the form of a tablet and oral suspension to be taken by mouth 4 times a day for an active ulcer and 2 times a day to prevent the recurrence of a healed ulcer. Take the medicine on an empty stomach (either 2 hours after or 1 hour before meals). Try to take it around the same time every day.

Read the prescription label carefully and take sucralfate exactly as prescribed. Do not change the dose, dosing frequency, or treatment duration without your doctor’s approval. 

Shake the liquid medicine well before use. Measure sucralfate oral suspension with a medicine dose measuring device such as the dosing syringe provided and not a kitchen spoon. 

While healing of the duodenal ulcer may occur in 1-2 weeks, your health care professional may prescribe sucralfate for up to 8 weeks to make sure the ulcer heals completely. You should continue taking the medicine regularly for the full prescribed length of treatment for it to be effective.

Ulcers in the duodenum are a chronic and recurrent problem. Short-term treatment with sucralfate can help to completely heal an ulcer. However, successful treatment with sucralfate does not change the post-healing frequency of ulcer formation, meaning it does not prevent future ulcers from forming.

Missed dose: If you miss a dose of sucralfate, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take the next dose according to your regular dosing schedule. Never take a double dose or extra medicine to make up for a missed dose.

Storage: Store at room temperature (between 15-30° C or 59-86° F) away from moisture, heat, and direct light in the original container, tightly closed. Do not freeze the liquid sucralfate. Do not store medications in the bathroom where they can be exposed to moisture and heat. Keep all medications safely out of reach of children and pets.

Unused medicine: Unused sucralfate should be disposed of in a way that other people, children, and pets cannot get to them. Do not throw sucralfate in the trash or flush it down the toilet. The best way to dispose of expired or unneeded sucralfate is through a drug take-back program or your local waste disposal company. Learn more about proper medication disposal

Sucralfate Warnings


Sucralfate (Carafate) Risks, Warnings, and Complications


Sucralfate can cause or worsen health problems in some people. Talk to your doctor or pharmacist about other medications for duodenal ulcers if you are at an increased risk of adverse reactions from this drug.

  • RISK IN PATIENTS WITH RENAL IMPAIRMENT: When you take sucralfate orally, small amounts of aluminum are absorbed from the gastrointestinal tract. People with normal kidney function taking the recommended doses of sucralfate and other aluminum-containing medications are able to excrete (get rid of) aluminum in urine. However, people with reduced kidney function, such as those with chronic renal failure or those on dialysis, are at risk of developing high aluminum levels. Signs and symptoms of aluminum toxicity can include muscle weakness, bone pain, confusion, and seizures. Older adults and people with kidney problems should consult their doctor for medical advice about whether sucralfate is safe for them.


Precautions Before Starting Sucralfate (Carafate)

Tell your doctor if you have ever had an allergic reaction to sucralfate, any of the active or inactive ingredients in sucralfate tablets or oral suspension, or any other drugs. Your pharmacy can give you a list of ingredients.

Give your doctor and pharmacist a complete list of your medications, including prescription drugs, over-the-counter medicines, vitamins, dietary supplements, and herbal products. This can help avoid possible interactions between sucralfate and your other medications.

Give your doctor a complete medical history. Sucralfate may not be right for people with certain medical conditions such as swallowing problems, diabetes, kidney disease, delayed gastric emptying, gastrointestinal disorders, and those receiving enteral feeding.

Tell your doctor if you are pregnant, could be pregnant, plan to get pregnant, or are breast feeding.

Precautions During Use of Sucralfate (Carafate)

Keep all your medical and lab appointments while on sucralfate. Tell your doctor if you have worsening symptoms. Follow your doctor’s dosing instructions carefully. Do not increase or decrease the dose, dosage frequency, or treatment duration without your doctor’s approval. 

If you want to take antacids when you feel ulcer pain, make sure you take them at least one-half hour away from your sucralfate dose.

Tell your doctor if you become pregnant while on sucralfate.

Concomitant use of certain medicines with sucralfate can affect how the medicines work or cause serious adverse effects.
