Sucralfate Guide: Uses, Dosage, Side Effects & Safe Use

Sucralfate is a medicine that protects the stomach and duodenal lining. Doctors prescribe it for active duodenal ulcers and to prevent ulcers in people at risk. Unlike antacids or acid blockers, sucralfate forms a sticky barrier over the damaged area so acid and enzymes cannot make the injury worse.

How to take sucralfate

You usually take sucralfate as a tablet or liquid suspension. The common adult dose for active duodenal ulcers is one gram four times a day, taken on an empty stomach about one hour before meals and at bedtime. Follow your doctor's instructions because doses vary by condition, age, and other medicines. If you miss a dose, take it as soon as you remember unless it is almost time for the next dose. Do not double up.

Side effects and interactions

Sucralfate has low absorption into the bloodstream, which lowers the chance of systemic side effects. Some people notice constipation, dry mouth, nausea, or stomach cramps. Serious allergic reactions are rare but seek help if you get hives, swelling, or trouble breathing. If you have kidney problems, talk to your doctor because aluminum from the medication can build up.

Sucralfate can interfere with absorption of other drugs. Take it at least two hours apart from fluoroquinolones like ciprofloxacin and levofloxacin, from tetracyclines, from digoxin, from phenytoin, from levothyroxine, and from some iron supplements. Ask your pharmacist how to space your medicines.

To use sucralfate correctly, swallow tablets whole with a glass of water. Shake the liquid well and measure with a proper device. Do not chew tablets unless your doctor says so. Stick to the schedule because continuous coverage helps the barrier stay in place while tissue heals.

If you buy sucralfate online, choose pharmacies that require a prescription and show licensing and contact details. Look for secure checkout and clear shipping info. Avoid sites that sell prescription drugs without a prescription or that hide their location. When you get your order, check the name, strength, and expiry date.

See your healthcare provider if symptoms do not improve in two to four weeks or if you have worsening pain, black stools, vomiting blood, or unexplained weight loss. These signs may need tests or a different treatment. If you are pregnant or breastfeeding, discuss risks and benefits before starting sucralfate.

Older adults and children may need dose changes. Doctors usually adjust use for children based on weight and for older adults based on kidney function. If you care for an older person, watch for constipation and check kidney labs if treatment continues. Do not give sucralfate to infants without clear medical advice.

Store sucralfate at room temperature away from moisture and heat. Dispose of expired medicine safely and ask your pharmacist about medication take back programs nearby options.

Simple habits make sucralfate safer and more effective. Take it on the right schedule, watch for interactions, report side effects, and keep follow up visits. Ask questions so your treatment goes smoothly.
