Does Carafate (sucralfate) cause side effects?
Carafate (sucralfate) is an anti-ulcer medication used to treat peptic ulcer disease and to prevent recurrent ulcers after healing of the ulcer has been achieved; to relieve or prevent ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs), but is less effective than misoprostol; and to treat patients with gastroesophageal reflux disease (GERD).
Off-label uses of Carafate are to prevent stress ulcers, which are ulcers associated with high degrees of physical stress (for example, extensive burns, surgery, and overwhelming infection) in hospitalized patients.
Common side effects of Carafate include
- spinning sensation (vertigo),
- dry mouth,
- vomiting, and
- gas (flatulence).
Drug interactions of Carafate include other drugs taken orally at the same time, because Carafate may bind to the drugs in the stomach and reduce absorption of the drugs.
- Carafate reduces the absorption of dolutegravir, cimetidine, digoxin, ketoconazole, levothyroxine, phenytoin, quinidine, ranitidine, tetracycline, theophylline, and fluoroquinolone antibiotics.
- All these medications should be taken at least two hours prior to Carafate.
- It is possible, if not likely, that many other drugs will interact similarly with Carafate.
- Therefore, it probably is prudent to take all medications at least 2 hours prior to Carafate.
All human data show no ill-effect of Carafate on the fetus. Carafate is considered safe during pregnancy.
Minimal if any Carafate penetrates into breast milk because so little is absorbed from the gastrointestinal tract. Although there are no data, Carafate is considered safe in breastfeeding mothers. Consult your doctor before breastfeeding.
Carafate (sucralfate) side effects list for healthcare professionals
Adverse reactions to sucralfate tablets in clinical trials were minor and only rarely led to discontinuation of the drug. In studies involving over 2,700 patients treated with sucralfate, adverse effects were reported in 129 (4.7%).
Constipation was the most frequent complaint (2%). Other adverse effects reported in less than 0.5% of the patients are listed below by body system:
- Gastrointestinal: diarrhea, dry mouth, flatulence, gastric discomfort, indigestion, nausea, vomiting
- Dermatological: pruritus, rash
- Nervous System: dizziness, insomnia, sleepiness, vertigo
- Other: back pain, headache
- Post-marketing cases of hypersensitivity have been reported with the use of sucralfate oral suspension, including anaphylactic reactions, dyspnea, lip swelling, edema of the mouth, pharyngeal edema, pruritus, rash, swelling of the face and urticaria.
- Cases of bronchospasm, laryngeal edema and respiratory tract edema have been reported with an unknown oral formulation of sucralfate.
- Cases of hyperglycemia have been reported with sucralfate. Bezoars have been reported in patients treated with sucralfate. The majority of patients had underlying medical conditions that may predispose to bezoar formation (such as delayed gastric emptying) or were receiving concomitant enteral tube feedings.
What drugs interact with Carafate (sucralfate)?
Some studies have shown that simultaneous sucralfate administration in healthy volunteers reduced the extent of absorption (bioavailability) of single doses of the following:
- fluoroquinolone antibiotics,
- tetracycline, and
Subtherapeutic prothrombin times with concomitant warfarin and sucralfate therapy have been reported in spontaneous and published case reports. However, two clinical studies have demonstrated no change in either serum warfarin concentration or prothrombin time with the addition of sucralfate to chronic warfarin therapy.
The mechanism of these interactions appears to be nonsystemic in nature, presumably resulting from sucralfate binding to the concomitant agent in the gastrointestinal tract. In all cases studied to date (cimetidine, ciprofloxacin, digoxin, norfloxacin, ofloxacin, and ranitidine), dosing the concomitant medication 2 hours before sucralfate eliminated the interaction.
Due to Carafate Oral Suspension's potential to alter the absorption of some drugs, Carafate Oral Suspension should be administered separately from other drugs when alterations in bioavailability are felt to be critical. In these cases, patients should be monitored appropriately.

Related Disease Conditions
Peptic Ulcer (Stomach Ulcer)
Peptic or stomach ulcers are ulcers are an ulcer in the lining of the stomach, duodenum, or esophagus. Ulcer formation is related to H. pylori bacteria in the stomach, use of anti-inflammatory medications, and cigarette smoking. Symptoms of peptic or stomach ulcers include abdominal burning or hunger pain, indigestion, and abdominal discomfort after meals. Treatment for stomach ulcers depends upon the cause.
GERD (Acid Reflux, Heartburn)
GERD (gastroesophageal reflux disease) is a condition in which the acidified liquid contents of the stomach backs up into the esophagus. The symptoms of uncomplicated GERD are: heartburn, regurgitation, and nausea. Effective treatment is available for most patients with GERD.
Ulcerative Colitis Diet Plan
An ulcerative colitis diet plan can help a person with the disease avoid foods and drinks that trigger flares. There also are foods that can soothe ulcerative colitis symptoms during a flare. Types of ulcerative colitis plans include a high-calorie diet, a lactose-free diet, a low-fat diet, a low-fiber diet (low-residue diet), or a low-salt diet. Self-management of ulcerative colitis using healthy lifestyle habits and a nutrient rich diet can be effective in management of the disease. Learn what foods to avoid that aggravate, and what foods help symptoms of the disease and increase bowel inflammation.
Ways to Relieve Acid Reflux (GERD, Heartburn)
Most people have experienced some sort of pain or discomfort following a large meal or a particular food that didn’t quite agree with their stomach. Acid reflux symptoms can happen without a specific underlying condition.
Ulcerative colitis is a chronic inflammation of the colon. Symptoms include abdominal pain, diarrhea, and rectal bleeding. Ulcerative colitis is closely related to Crohn's disease, and together they are referred to as inflammatory bowel disease. Treatment depends upon the type of ulcerative colitis diagnosed.
Crohn's Disease vs. Ulcerative Colitis (UC)
Crohn's disease and ulcerative colitis are diseases that cause inflammation of part of or the entire digestive tract (GI). Crohn's affects the entire GI tract (from the mouth to the anus), while ulcerative colitis or ulcerative colitis only affects the large and small intestine and ilium. Researchers do not know the exact cause of either disease. About 20% of people with Crohn's disease also have a family member with the disease. Researchers believe that certain factors may play a role in causing UC. Both Crohn's disease and ulcerative colitis are a type of inflammatory bowel disease, or IBD. Crohn's disease and ulcerative colitis both have similar symptoms and signs, for example, nausea, loss of appetite, fatigue, weight loss, episodic and/or persistent diarrhea, fever, abdominal pain and cramping, rectal bleeding, bloody stools, joint pain and soreness, eye redness, or pain. Symptoms unique to Crohn’s disease include anemia and skin changes. Symptoms of unique to ulcerative colitis include, certain rashes, an urgency to defecate (have a bowel movement). Doctors diagnose both diseases with similar tests and procedures. While there is no cure for either disease, doctors and other health care professionals can help you treat disease flares, and manage your Crohn's or ulcerative colitis with medication, diet, nutritional supplements, and/or surgery.
Nonsteroidal Anti-inflammatory Drugs and Ulcers
Nonsteroidal anti-inflammatory drugs (NSAIDs) are prescribed medications for the treatment of inflammatory conditions. Examples of NSAIDs include aspirin, ibuprofen, naproxen, and more. One common side effect of NSAIDs is peptic ulcer (ulcers of the esophagus, stomach, or duodenum). Side effects, drug interactions, warnings and precautions, and patient safety information should be reviewed prior to taking NSAIDs.
Beyond Food: What Triggers Heartburn and GERD?

GERD (Acid Reflux) in Infants and Children
GERD (gastroesophageal reflux disease) is the upward movement of stomach content, including acid, into the esophagus and sometimes into or out of the mouth. Common symptoms of GERD in children include colic, feeding problems, poor growth, frequent vomiting or coughing, heartburn, regurgitation, recurrent wheezing, pneumonia, choking, or gagging. Treatment may involve elevating the child's bed, keeping the child upright after eating, limiting foods that seem to make the reflux worse, encouraging your child to exercise, and serving several small meals a day.
Is Ulcerative Colitis Curable?
Ulcerative colitis is an inflammatory bowel disease (IBD) that affects the inner lining of the large intestine (large bowel or colon) leading to erosion and ulcers. It is also associated with various manifestations outside of the colon, such as inflammation of the eyes, joints, skin, and lungs. Ulcerative colitis is a lifelong illness with no specific cause or cure. Patients have repeated cycles of flare-ups and disappearance of the disease.
How Serious Is Ulcerative Colitis?
Ulcerative colitis (UC) is a lifelong disease with constant periods of flare-ups and remissions (periods without symptoms, which may last for weeks or years). Presently, there is no permanent medical cure for it, but there are various medications that can provide symptomatic relief, reduce inflammation and manage flare-ups.
