What is Ulserral?
Ulserral is in a group of drugs called histamine receptor antagonists. Ulserral works by decreasing the amount of acid your stomach produces.
Ulserral is used to treat and prevent certain types of ulcer, and to treat conditions that cause the stomach to produce too much acid. Ulserral is also used to treat gastroesophageal reflux disease (GERD), when stomach acid backs up into the esophagus and causes heartburn.
Ulserral may also be used for other purposes not listed in this medication guide.
Ulserral indications
Ulserral Tablets USP are indicated in:
- 1.
- Short-term treatment of active duodenal ulcer. Most patients heal within 4 weeks and there is rarely reason to use Ulserral at full dosage for longer than 6 to 8 weeks. Concomitant antacids should be given as needed for relief of pain. However, simultaneous administration of oral Ulserral and antacids is not recommended, since antacids have been reported to interfere with the absorption of oral Ulserral.
- 2.
- Maintenance therapy for duodenal ulcer patients at reduced dosage after healing of active ulcer. Patients have been maintained on continued treatment with Ulserral 400 mg at bedtime for periods of up to five years.
- 3.
- Short-term treatment of active benign gastric ulcer. There is no information concerning usefulness of treatment periods of longer than 8 weeks.
- 4.
- Erosive gastroesophageal reflux disease (GERD). Erosive esophagitis diagnosed by endoscopy. Treatment is indicated for 12 weeks for healing of lesions and control of symptoms. The use of Ulserral beyond 12 weeks has not been established.
- 5.
- The treatment of pathological hypersecretory conditions (i.e., Zollinger-Ellison Syndrome, systemic mastocytosis, multiple endocrine adenomas).
How should I use Ulserral?
Use Ulserral suspension as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Ulserral suspension by mouth with or without food.
- Shake well before each use.
- Take Ulserral suspension with a full glass of water (8oz/240 mL).
- Use a measuring device marked for medicine dosing. Ask your pharmacist for help if you are unsure of how to measure this dose.
- If you also take cephalosporin (eg, cephalexin), itraconazole, or ketoconazole, take it at least 2 hours before taking Ulserral suspension. Check with your doctor if you have questions.
- If you miss a dose of Ulserral suspension and you are taking it regularly, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Ulserral suspension.
Uses of Ulserral in details
Ulserral is used to treat ulcers of the stomach and intestines and prevent them from coming back after they have healed. This medication is also used to treat certain stomach and throat (esophagus) problems caused by too much stomach acid (e.g., Zollinger-Ellison syndrome, erosive esophagitis) or a backward flow of stomach acid into the esophagus (acid reflux disease/GERD). Decreasing extra stomach acid can help relieve symptoms such as stomach pain, heartburn, difficulty swallowing, persistent cough, and trouble sleeping. It can also prevent serious acid damage to your digestive system (e.g., ulcers, cancer of the esophagus).
Ulserral belongs to a class of drugs commonly called H2 blockers. It works by reducing the amount of acid in your stomach.
This medication is also available without a prescription. It is used to treat occasional heartburn caused by too much acid in the stomach (also called acid indigestion or sour stomach). It is also used to prevent heartburn and acid indigestion caused by certain foods and beverages. If you are taking this medication for self-treatment, it is important to read the manufacturer's package instructions carefully so you know when to consult your doctor or pharmacist.
How to use Ulserral
Take this medication by mouth with or without food as directed by your doctor.
The dosage and length of treatment are based on your medical condition and response to therapy. Follow your doctor's instructions carefully. If you are also taking antacids to relieve stomach pain as recommended by your doctor, separate them from this medication by at least 1 hour.
Take this medication regularly as prescribed in order to get the most benefit from it. To help you remember, take it at the same time(s) each day. Do not increase your dose or take it more often than directed. Continue to take this medication for the prescribed length of treatment even if you are feeling better. Stopping treatment too early may delay the healing process.
If you are using nonprescription Ulserral for self-treatment of acid indigestion or heartburn, take 1 tablet by mouth with a glass of water as needed. To prevent heartburn, take 1 tablet by mouth with a glass of water right before or up to 30 minutes before eating food or drinking beverages that cause heartburn. Do not take more than 2 tablets in 24 hours unless directed by your doctor. Do not take for more than 14 days in a row without talking with your doctor.
Inform your doctor if your symptoms do not improve or if they worsen.
Ulserral description
A histamine congener, it competitively inhibits histamine binding to histamine H2 receptors. Ulserral has a range of pharmacological actions. It inhibits gastric acid secretion, as well as pepsin and gastrins output. It also blocks the activity of cytochrome P-450 which might explain proposals for use in neoadjuvant therapy. [PubChem]
Ulserral dosage
Duodenal Ulcer
Active Duodenal UlcerClinical studies have indicated that suppression of nocturnal acid is the most important factor in duodenal ulcer healing. This is supported by recent clinical trials. Therefore, there is no apparent rationale, except for familiarity with use, for treating with anything other than a once-daily at bedtime oral dosage regimen.
In a U.S. oral dose-ranging study of 400 mg at bedtime, 800 mg at bedtime and 1600 mg at bedtime, a continuous dose response relationship for ulcer healing was demonstrated.
However, 800 mg at bedtime is the dose of choice for most patients, as it provides a high healing rate (the difference between 800 mg at bedtime and 1600 mg at bedtime being small), maximal pain relief, a decreased potential for drug interactions and maximal patient convenience. Patients unhealed at four weeks, or those with persistent symptoms, have been shown to benefit from two to four weeks of continued therapy.
It has been shown that patients who both have an endoscopically demonstrated ulcer larger than 1 cm and are also heavy smokers (i.e., smoke one pack of cigarettes or more per day) are more difficult to heal. There is some evidence which suggests that more rapid healing can be achieved in this subpopulation with Ulserral 1600 mg at bedtime. While early pain relief with either 800 mg at bedtime or 1600 mg at bedtime is equivalent in all patients, 1600 mg at bedtime provides an appropriate alternative when it is important to ensure healing within four weeks for this subpopulation. Alternatively, approximately 94% of all patients will also heal in eight weeks with Ulserral 800 mg at bedtime.
Other Ulserral oral regimens in the U.S. which have been shown to be effective are: 300 mg four times daily, with meals and at bedtime, the original regimen with which U.S. physicians have the most experience, and 400 mg twice daily, in the morning and at bedtime.
Concomitant antacids should be given as needed for relief of pain. However, simultaneous administration of oral Ulserral and antacids is not recommended, since antacids have been reported to interfere with the absorption of Ulserral.
While healing with Ulserral often occurs during the first week or two, treatment should be continued for 4 to 6 weeks unless healing has been demonstrated by endoscopic examination.
Maintenance Therapy for Duodenal Ulcer
In those patients requiring maintenance therapy, the recommended adult oral dose is 400 mg at bedtime.
Active Benign Gastric Ulcer
The recommended adult oral dosage for short-term treatment of active benign gastric ulcer is 800 mg at bedtime, or 300 mg four times a day with meals and at bedtime. Controlled clinical studies were limited to six weeks of treatment. 800 mg at bedtime is the preferred regimen for most patients based upon convenience and reduced potential for drug interactions. Symptomatic response to Ulserral does not preclude the presence of a gastric malignancy. It is important to follow gastric ulcer patients to assure rapid progress to complete healing.
Erosive Gastroesophageal Reflux Disease (GERD)
The recommended adult oral dosage for the treatment of erosive esophagitis that has been diagnosed by endoscopy is 1600 mg daily in divided doses (800 mg twice daily or 400 mg four times daily) for 12 weeks. The use of Ulserral beyond 12 weeks has not been established.
Pathological Hypersecretory Conditions (such as Zollinger-Ellison Syndrome)
Recommended adult oral
Dosage: 300 mg four times a day with meals at bedtime. In some patients it may be necessary to administer higher doses more frequently. Doses should be adjusted to individual patient needs, but should not usually exceed 2400 mg per day and should continue as long as clinically needed.
Dosage Adjustments for Patients with Impaired Renal Function
Patients with severely impaired renal function have been treated with Ulserral. However, such dosage has been very limited. On the basis of this experience the recommended dosage is 300 mg every 12 hours orally. Should the patient’s condition require, the frequency of dosing may be increased to every 8 hours or even further with caution. In severe renal failure, accumulation may occur and the lower frequency of dosing comparable with an adequate patient response should be used. When liver impairment is also present, further reductions in dosage may be necessary. Hemodialysis reduces the level of circulating Ulserral. Ideally, the dosage schedule should be adjusted so that the timing of a scheduled dose coincides with the end of hemodialysis.

Ulserral side effects
See also:
What are the possible side effects of Ulserral?
Adverse effects reported in patients taking Ulserral are described below by body system. Incidence figures of 1 in 100 and greater are generally derived from controlled clinical studies.
Gastrointestinal
Diarrhea (usually mild) has been reported in approximately 1 in 100 patients.
CNS
Headaches, ranging from mild to severe, have been reported in 3.5% of 924 patients taking 1600 mg/kg, 2.1% of 2,225 patients taking 800 mg/day and 2.3% of 1,897 patients taking placebo. Dizziness and somnolence (usually mild) have been reported in approximately 1 in 100 patients on either 1600 mg/day or 800 mg/day.
Reversible confusional states, e.g., mental confusion, agitation, psychosis, depression, anxiety, hallucinations, disorientation, have been reported predominately but not exclusively, in severely ill patients. They have usually developed within 2–3 days of initiation of Ulserral therapy and have cleared within 3–4 days of discontinuation of the drug.
Endocrine
Gynecomastia has been reported in patients treated for one month or longer. In patients being treated for pathological hypersecretory states, this occurred in about 4% of cases while in all others the incidence was 0.3% to 1% in various studies. No evidence of induced endocrine dysfunction was found, and the condition remained unchanged or returned toward normal with continuing Ulserral treatment.
Reversible impotence has been reported in patients with pathological hypersecretory disorders, e.g., Zollinger-Ellison Syndrome, receiving Ulserral particularly in high doses, for at least 12 months (range 12–79 months, mean 38 months). However, in large-scale surveillance studies at regular dosage, the incidence has not exceeded that commonly reported in the general population.
Hematologic
Decreased white blood cell counts in Ulserral-treated patients (approximately 1 per 100,000 patients), including agranulocytosis (approximately 3 per million patients), have been reported, including a few reports of recurrence on rechallenge. Most of these reports were in patients who had serious concomitant illnesses and received drugs and/or treatment known to produce neutropenia. Thrombocytopenia (approximately 3 per million patients) and, very rarely, cases of pancytopenia or aplastic anemia have also been reported. As with some other H2-receptor antagonists, there have been extremely rare reports of immune hemolytic anemia.
Hepatobiliary
Dose-related increases in serum transaminase have been reported. In most cases they did not progress with continued therapy and returned to normal at the end of therapy. There have been rare reports of cholestatic or mixed cholestatic-hepatocellular effects. These were usually reversible. Because of the predominance of cholestatic features, severe parenchymal injury is considered highly unlikely. However, as in the occasional liver injury with other H2-receptor antagonists, in exceedingly rare circumstances fatal outcomes have been reported.
There has been reported a single case of biopsy-proven periportal hepatic fibrosis in a patient receiving Ulserral.
Rare cases of pancreatitis, which cleared on withdrawal of the drug, have been reported.
Hypersensitivity
Rare cases of fever and allergic reactions including anaphylaxis and hypersensitivity vasculitis, which cleared on withdrawal of the drug have been reported.
Renal
Small, possibly dose-related increases in plasma creatinine, presumably due to competition for renal tubular secretion, are not uncommon and do not signify deteriorating renal function. Rare cases of interstitial nephritis and urinary retention, which cleared on withdrawal of the drug, have been reported.
Cardiovascular
Rare cases of bradycardia, tachycardia and A-V heart block have been reported with H2-receptor antagonists.
Musculoskeletal
There have been rare reports of reversible arthralgia and myalgia; exacerbation of joint symptoms in patients with preexisting arthritis has also been reported. Such symptoms have usually been alleviated by a reduction in Ulserral dosage. Rare cases of polymyositis have been reported, but no causal relationship has been established.
Integumental
Mild rash and, very rarely, cases of severe generalized skin reactions including Stevens-Johnson syndrome, epidermal necrolysis, erythema multiforme, exfoliative dermatitis and generalized exfoliative erythroderma have been reported with H2-receptor antagonists. Reversible alopecia has been reported very rarely.
Immune Function
There have been extremely rare reports of strongyloidiasis hyperinfection in immunocompromised patients.

What is the most important information I should know about Ulserral?
Use this medication exactly as directed on the label, or as your doctor has prescribed it for you. Do not use more of the medication than recommended. Do not use the medication for longer than recommended.
Avoid taking antacids unless your doctor recommends them for heartburn pain. Follow your doctor's advice about the type of antacid to use and when to use it. You may not be able to take the antacid at the same time you take your dose of Ulserral.
Taking Ulserral may make you more susceptible to virus that can cause pneumonia. This has occurred most often in elderly people and in those with diabetes, a weak immune system, or chronic lung disease. Before using Ulserral, tell your doctor if you have any of these conditions.
There are many other drugs that can interact with Ulserral. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
Heartburn can be confused with early symptoms of heart attack. Seek emergency medical attention if you have chest pain or heavy feeling, dizziness, pain spreading to the arm or shoulder, sweating, nausea or vomiting, and a general ill feeling.
