FM 40MG TABLET belongs to a group of medicines called ‘H2-receptor antagonists that reduce acid production in the stomach. It treats stomach ulcers (gastric and duodenal ulcers), reflux oesophagitis, and Zollinger-Ellison syndrome. Stomach ulcers are painful sores present on the inner lining of the stomach. Reflux esophagitis is the inflammation of the oesophagus (food pipe) that causes the backward flow of stomach contents into the oesophagus. Zollinger-Ellison syndrome is a condition in which the tumours formed in the pancreas (produces enzymes for digestion) and duodenum (part of the small intestine) increase stomach acids.

FM 40MG TABLET contains ‘Famotidine’, which acts as an antacid. It inhibits the H2-receptors present in stomach cells. It reduces the production of acid and the volume of gastric secretions. As excess acid can cause the inflammation of the oesophagus, stomach, and intestine, a reduction in the production leads to improvement in the symptoms and condition.

FM 40MG TABLET must be taken in the dose and duration advised by the doctor. Sometimes, you may experience headaches, dizziness, constipation, and diarrhoea. Most of these side effects of FM 40MG TABLET do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

FM 40MG TABLET is not recommended for use in children and breastfeeding mothers. Do not take FM 40MG TABLET if you are allergic to famotidine, other H2 receptor antagonists, or any other ingredients present in it. Before taking FM 40MG TABLET, inform your doctor if you are taking prescription or non-prescription medications, including antacids, any nutritional supplements, or herbal products. Inform your doctor if you have any gastrointestinal problems, Helicobacter pylori (H. pylori) infection, lactose intolerance, or kidney diseases. Inform your doctor if you are pregnant or planning to become pregnant.

FM 40MG TABLET belongs to a class of medications called H2 receptor antagonists. Histamine binds to the H2 receptors present in parietal cells of the stomach and stimulates the production of acid. FM 40MG TABLET bind to these receptors and blocks the histamine action. It also decreases the gastric secretion content. It also reduces the gastric secretion stimulated by food, caffeine, insulin, and pentagastrin. Caffeine, insulin (used in the treatment of diabetes), and pentagastrin (a synthetic drug that aid in diagnosing thyroid malignancy) stimulate gastric acid secretion.

FM 40MG TABLET should not be used in children and breastfeeding mothers. Do not take FM 40MG TABLET if you are allergic to famotidine, other H2 receptor antagonists, or any other ingredients present in it. Before taking FM 40MG TABLET, inform your doctor if you have any gastrointestinal problems, Helicobacter pylori infection, lactose intolerance, or kidney diseases. Inform your doctor if you are pregnant or planning to become pregnant.

Drug-drug interactions: FM 40MG TABLET may interact with other antacids, antifungal drugs (ketoconazole and itraconazole), medications used to treat hepatitis C (Ledipasvir / Sofosbuvir), medications used to treat leukaemia (nilotinib, dasatinib), antibiotic medications (cefditoren), and HIV medications (rilpivirine, fosamprenavir).

Drug-food interactions: FM 40MG TABLET may interact with alcohol and increase the risk of side effects.

Drug-disease interactions: FM 40MG TABLET should be used with caution in patients with gastrointestinal bleeding, lactose intolerance, H. pylori infection, and renal dysfunction.

Stomach ulcer: Stomach ulcers, also called gastric ulcers, are sores present in the inner lining of the digestive tract (oesophagus, stomach, or small intestine). It occurs when acid (produced during digestion) in the stomach damages the inner lining. Frequent use of pain killers such as aspirin and an underlying H. pylori infection may cause stomach ulcers. Symptoms include nausea, changes in appetite, bloody or dark stools, unexplained weight loss, vomiting, and indigestion.

Reflux esophagitis: Reflux esophagitis is also referred to as gastroesophageal reflux disease (GERD). It occurs when stomach acid frequently flows back to the oesophagus (food pipe). This backflow (acid reflux) irritates the food pipe and causes heartburn. Symptoms include heartburn, sour or bitter taste in the mouth, and difficulty swallowing.

Zollinger-Ellison syndrome: Zollinger-Ellison syndrome is a rare condition in which tumours form in the pancreas (organ present near the abdomen and produces enzymes for digestion) or duodenum (first section of the small intestine) leads to an increase in the production of stomach acid. Symptoms include nausea, vomiting, abdominal pain, diarrhoea, and weight loss.
